Online shopping addiction has become a worsening problem in China for males and females. Based on 904 shoppers, this study examines the relationship between hedonic shopping motivations and compulsive online buying and investigates gender differences using gender theories. This study finds that different hedonic motivations contribute to compulsive online buying. Gratification seeking and idea shopping are key motivations for compulsive online buyers (females are mostly gratification seekers, while males are mostly information seekers). Conversely, value and role-play shopping reduce compulsive online buying, with a stronger effect on females; however, role-play shopping was unrelated to compulsive online buying for males.

  • Guillaume Bagnarosa, Mark Cummins, Michael Dowling, Fearghal Kearney (2022) Commodity risk in European dairy firms, European Review of Agricultural Economics, Volume 49, Issue 1, January 2022, Pages 151–181

We apply a multivariate mixed-data sampling (MIDAS) conditional quantile regression technique to understand the dairy commodity exposure of European dairy firms. Leveraging a theoretically sound hedonic dairy pricing framework, we show that our approach is able to identify both market and operational risk. Profit margins for butter and milk price are particularly important for operational performance. Additional tests are provided, including an application of MIDAS quantile on a period of amplified dairy market risk. Our approach thus allows dairy firms to gain new perspectives on the significant risks posed by the current structure of dairy production in Europe.

We construct a spatiotemporal frame for the study of spatial economic and ecological patterns generated by transboundary pollution. Space is continuous and polluting emissions originate in the intensity of use of the production input. Pollution flows across locations following a diffusion process. The objective functional of the economy is to set the optimal production policy over time and space to maximize welfare from consumption, taking into account a negative local pollution externality and the diffusive nature of pollution. Our framework allows for space and time dependent preferences and productivity, and does not restrict diffusion speed to be space-independent.  Accordingly, we develop a methodology to investigate the environmental and economic implications of spatiotemporal heterogeneity. We propose a method for an analytical characterization of the optimal paths. An application to technological spillovers is proposed for illustration. We focus on the determination of the optimal short-term spatiotemporal dynamics induced by the resulting non-autonomous problems

The purpose of this study is to investigate the development of brand hate based on the case of Italian luxury fashion house Dolce & Gabbana in China. The strategy adopted in this study is a single in-depth case study. Qualitative methods are applied in both the data collection and analysis. The findings identified six distinct stages through which brand hate can develop: awareness, anger, amplification, antagonism, action and apathy. The case is specific to a luxury brand and the Chinese cultural context. Practitioners need to consider how business strategies can be adapted to manage the six stages of the manifestation of brand hate. A “proactive” approach is needed to avoid arousing brand hate, while a “reactive” approach is needed to manage its potential ramifications. There has been a paucity of anti-consumption research within the business strategy literature. To the best of the authors’ knowledge, the focus on China makes this the first study to investigate brand hate within a Chinese cultural contex.

  • Thomas Conlon, John Cotter, Emmanuel Eyiah-Donkor (2022) The illusion of oil return predictability: The choice of data matters! Journal of Banking & Finance, Volume 134, 2022, 106331

Previous studies document statistically significant evidence of crude oil return predictability by several forecasting variables. We suggest that this evidence is misleading and follows from the common use of within-month averages of daily oil prices in calculating returns used in predictive regressions. Averaging introduces a bias in the estimates of the first-order autocorrelation coefficient and variance of returns. Consequently, estimates of regression coefficients are inefficient and associated t-statistics are overstated, leading to false inference about the true extent of in-sample and out-of-sample return predictability. On the contrary, using end-of-month data, we do not find convincing evidence for the predictability of oil returns. Our results highlight and provide a cautionary tale on how the choice of data could influence hypothesis testing for return predictability.

A two-stage decentralized supply chain operates in make-to-order under a stochastic environment. Each stage represents an independent firm that quotes a price and a delivery time to its downstream while satisfying a minimum service level. The mean demand depends on the final price and the overall delivery time quoted to the customers by the whole supply chain. We study three settings. First, the downstream, as a Stackelberg leader, decides its price and controls both delivery times, and the upstream, as a follower, reacts by deciding its own price. Second, the downstream decides its delivery time and controls prices, and the upstream reacts by quoting its own delivery time. Third, the upstream, as a leader, decides its price and controls both delivery times, and the downstream, as a follower, decides its own price. This is the first study to investigate the delivery time quotation and pricing in decentralized supply chains where each firm performs operations and has a delivery time, and the demand is function of both upstream and downstream delivery times in addition to final price. We characterize analytically the optimal strategy under each setting and derive insights into the interplay between local delivery times, overall delivery time, prices, demand, and profits. We investigate how delivery times can be used to coordinate the supply chain and the impact of firms’ capacities.

This paper examines and compares financial market reaction and recovery of four broad classes of financial assets – equity indexes, precious metals, 10-year benchmark bonds and cryptocurrencies, to the COVID-19 pandemic. The data set comprises daily observations of close prices in the selected markets from 17-04-2018 to 20-06-2021. Using the Yang and Zhao (2020) and Koenker and Xiao (2004) quantile unit-root tests for return persistence, we find heterogeneity in reactions and recovery patterns not only across asset classes, but also within them. Specifically, we find strong potential for mean reversion in equity markets even at high levels of shocks. While gold offers limited mean reversion, platinum shows very strong resistance to the COVID. Government bonds show small declines in value to the COVID in addition to high persistence. Cryptocurrencies, as a group, turn out to be the riskiest in the long-term, with more than a 50% decline in value coupled with high degrees of persistence. Our results raise questions as to the safe haven characteristics of the newly-popular Bitcoin. Our findings are useful for policy makers and investors through a better understanding of differences in the potential for mean reversion provided by different asset classes.

The sustainable consumption and integration of digital solutions with respect to sustainable consumption have been encouraged by the new European circular economy action plan. Digital adoption has been accelerated by the COVID-19 pandemic; companies have been challenged to rapidly adapt to the constant evolution of consumer needs and expectations, leading to valuable insights into the advancement of green business practices and a consequent rethinking of their business model. The purpose of this paper is to investigate the major shifts in sustainable consumer behavior on the Romanian retail market within the context of the Green European Deal, and retailers’ priorities in agilely adapting to these significant evolutions. Based on a comprehensive literature review on these major shifts and significant evolutions at the national and international levels, a quantitative study was carried out to evaluate the Romanian retail market and identify the major challenges faced by retailers in dealing with the new set of priorities. The data collection was conducted via a survey used in the retail environment, applied within a Romanian supermarket chain. The Romanian retail sector has a particular configuration, which may have an impact upon the study’s generalizability. Located in Central and Eastern Europe at the crossroads of the EU, the Commonwealth of Independent States (CIS), and the Middle East, Romania is a leading destination for foreign direct investment, and it is recognized for the similarities of its distribution and sales channels, the range of its retail outlets, and the local retail market dominance on the Big Box segment by reputed major retailers. A spectacular evolution is recorded in Romania’s e-commerce market, including from the point of view of the long-standing and memorable traditional relationship between Romania and China which was confirmed more recently by Romanian consumers who prefer to buy online from stores in China. Our consumer research provides retailers with deep consumer insights with regard to their priorities in their agile adaptation. According to our research, Romanian consumers are environmentally concerned consumers, displaying an increased awareness about the important role they play with respect to impacting sustainable production and consumption by adopting green purchase behavior. Our study also points to the fact that retailers, although faced with challenges in targeting consumers with customized messages to reinforce their brand perception on sustainability issues, do pay considerable attention to sustainability as a personal value embraced by consumers and are willing to focus on digitizing their business processes to enable new, sustainable business models

Negative customer engagement (NCE) has received little research attention. The effect of NCE on market-based assets (i.e. brand equity) and firm performance remains a particularly underexplored topic despite the increasing rates of NCE with brands across a multitude of service industries. This study develops a comprehensive and parsimonious model of the causes and consequences of NCE. In this study, time-series cross-sectional data from the US airline industry and a simultaneous equation modelling technique were used to provide evidence for why some firms experience more NCE than others. The results indicate that airlines with a higher relative marketing capability (RMC) experience fewer NCE incidents in the form of customer complaints. A firm’s relative marketing capability determines the extent to which its customers engage negatively with it. Furthermore, deviating from earlier studies which explored the direct and immediate relationships between the focal variables, this study theoretically argued and empirically demonstrated that brand equity mediates the nexus between NCE and financial performance. That is, the number of NCE incidents a firm experiences affects its brand equity, which in turn impacts its financial performance, as measured by Tobin’s q and market value added (MVA).

Should we teach in hybrid mode or fully online? We examine the teaching model’s role (hybrid versus fully online) in the service–profit chain in higher education institutions using survey data from 93 faculty members and 366 students from three American universities. We find that faculty members’ satisfaction and the MBA program expectations improve MBA word-of-mouth by enhancing the MBA quality, MBA value, class satisfaction, and MBA loyalty. Additionally, we discover that the hybrid teaching model more strongly reinforces this chain of effects than the fully online model. IT creates the integration of differential value into a hybrid teaching style.

Recent developments in the innovation literature suggest that even when an organization truthfully implements the adopted R&D policy, it may still fail to achieve its intended goals, a phenomenon called means-ends decoupling. We employ a systematic literature review to answer the question of “what is the current state of knowledge in the phenomenon of means-ends decoupling in the literature” and “where it can move in the future.” Our paper provides a framework that delineates means-ends decoupling from policy-practice decoupling and identifies the underlying mechanisms that explain when and how means-ends decoupling may occur within an organization’s activities.

This study investigates challenges and opportunities that regionally expanding emerging market banks face. We focus on four leading Middle Eastern banks’ internationalization trajectories and performances by employing a case study approach. We first examine the four banks’ choices of target markets, entry sequencing, and  entry modes over time and then analyze their entry strategies and post-entry financial performances in one of their key markets, Turkey. We show that the success of regional expansion strategies depends on parent bank characteristics such as scale and capital strength, strategic decisions regarding entry mode and timing, and host market structure and competitiveness.

This research identifies how windows of opportunity (WOP) emerge and influence the catching up process of the Chinese electric vehicle (EV) industry between 1995 and 2018 by analyzing technological, institutional, and market demand elements of the WOP. Our case study indicates that government policies play a vital role. Along with the development of Chinese EV industry, government policies evolve from initiation to consolidation and finally reposition. Meanwhile, WOP emerge but diverge in their patterns; from institutional to technological and finally to the market demand WOP. Our study further elaborates the interplay of the above-mentioned three kinds of WOP, which provide feedback to the government authorities and work jointly to facilitate the catching up of Chinese EV industry. Based on the evidence of the Chinese EV industry, we continue the discussion of the emergence and interplays of WOP during the industrial catching up in latecomer countries like China, who is eager to build an energy-saving industry. Our case study provides a fine-grained analysis of policy evolution and its role in opening the different kinds of WOP, which eventually contribute to the successful catching up of a latecomer industry. It also offers new insights for policymakers when building a sustainable system

Academic scientists are encouraged to pursue research that delivers both scientific and societal impact. This may involve a search for alternative mechanisms of social approval which lead to endorsement of scientists’ research goals. We explore how scientists mobilise and accumulate different forms of legitimacy, which might favour their participation in practices related to innovation and societal impact. We propose three specific sources of scientific legitimacy: i) scientists’ social networks (research-related legitimacy ties), ii) prominence in the relevant academic community (reputation-based legitimacy); and direct contact with the primary beneficiaries of the research (beneficiary-based legitimacy). To explain scientists’ participation in activities oriented towards innovation and societal impact, we test the significance of each of these sources of legitimacy and their potential interplay empirically, using a large sample of Spanish biomedical scientists

This article investigates the theoretical and empirical relationships between organisational punishment and productivity. We do so by highlighting the contributions of two academic fields to this topic: management and economics. We underscore the many common theoretical and empirical grounds across management and economics. We heighten, in particular, how motivation and learning theories have contributed to the development of both theoretical and empirical research on this topic. This article also argues that this debate could be significantly advanced if insights stemming from industrial relations and labour process theory were also considered, as these disciplines have traditionally focused on macro-issues such as how changes in the economic/institutional contexts may affect the likelihood that organisations will resort to unishment. In order to foster future research on this topic, three research themes were developed: (a) freedom of choice and the role of contract completeness; (b) perception of punishment, monitoring and productivity; and (c) punishment, productivity and exogenous variables.

Faroque, Lasse Torkkeli, Hafiza Sultana, Mahabubur Rahman (2022) Network exploration and exploitation capabilities and foreign market knowledge: The enabling and disenabling boundary conditions for international performance. Industrial Marketing Management, Volume 101, 2022, Pages 258-271

This empirical study analyzes how strategic orientations influence the relationships between exploration and exploitation-related networking capabilities, foreign market knowledge, and market performance of 198 internationally operating firms in Bangladesh. The results of hierarchical regression showed that a higher level of network exploration capability and network exploitation capability individually generate greater foreign market knowledge. In addition, our results show that international entrepreneurial orientation reinforces the positive effect of network exploration capability. The positive association between market knowledge and performance, in turn, is accentuated by a proactive export market orientation but attenuated by a responsive export market orientation. These findings suggest that, while both types of networking capabilities are beneficial to develop stocks of foreign market knowledge, firms can acquire and create greater knowledge if they strategically align entrepreneurial orientation with network exploration capability. Further, to use this market knowledge with the goal of improving their position in international markets, firms need to develop a proactive rather than a responsive export market orientation. The current study contributes to the literature on networking capabilities by analyzing firms’ networking capabilities with the lens of exploration-exploitation typologies and incorporating strategic orientations as the contextual factors of such capabilities

  • Amirhossein Sadoghi, Jan Vecer (2021) Optimal liquidation problem in illiquid markets. European Journal of Operational Research, Volume 296, Issue 3, 2022, pp 1050-1066

In this research, we develop a trading strategy for the optimal liquidation problem of large-order trading, with different market microstructures, in an illiquid market. We formulate the liquidation problem as a discrete-time Markov decision process. In this market, the flow of liquidity events can be viewed as a point process with stochastic intensity. Based on this fact, we model the price impact as a linear function of a self-exciting dynamic process. Our trading algorithm is designed in such a way that when no favourite orders arrive in the Limit Order Book (LOB), the optimal solution takes offers from the lower levels of the LOB. This solution might contradict conventional optimal execution methods, which only trade with the best available limit orders; however, our findings show that the proposed strategy may reduce final inventory costs by preventing orders not being filled at earlier trading times. Furthermore, the results indicate that an optimal trading strategy is dependent on characteristics of the market microstructure.

Applied Economics R&D investments: a quantile regression approach. Applied Economics, 54:17, 1974-1988

This study investigates the impact of financial flexibility and academic experience of a firm’s board on corporate R&D investments in China. It also explores the moderating role of directors’ academic experience on the relationship between financial flexibility and R&D investments. We apply ordinary least square, fixed effects and quantile regression analysis using panel data of 2,195 A-share firms listed on Shanghai and Shenzhen stock exchanges during the period from 2011 to 2018. We find that both financial flexibility and directors’ academic experience promote R&D investments of Chinese non-financial firms. We also observe that directors’ academic experience weakens the positive impact of financial flexibility on R&D investments for firms operating in underdeveloped financial regions, whereas it strengthens the positive impact of financial flexibility on R&D investments for firms operating in developed financial regions. Our quantile regression results suggest that academic experience has a highly significant positive moderating impact on the financial flexibility of lower R&D investment firms relative to high R&D investment firms. These results are robust to alternate proxy of financial flexibility and endogeneity issues due to reverse causality.

Using a large panel dataset of 861 listed Chinese firms, the present study investigates whether corporate social responsibility (CSR) affects firm-value. It examines the influence of five CSR dimensions on firm-value. Then, it pinpoints the moderating impact of industry-sensitivity and power concentration of the CEO. In contrast to developed economy’s evidence, the results show an overall negative impact of CSR on firm-value. Looking closer at the dimensions separately, we find a negative impact of most of the CSR dimensions and a positive impact of some other CSR dimensions on firm-value. However, we observe that CSR enhances the value of firms operating in sensitive industries. Similarly, we find that a powerful CEO can also create firm-value through CSR by aligning CSR practices with the firms’ objectives. Our results are sufficiently rigorous to alternate proxies of CSR.

By combining expatriate social support and online community literature, we explore the role Internet-based expat platforms can play in creating complementary opportunities of interaction leading to informational, emotional and instrumental support for expatriates in the host country. For this purpose, two studies were conducted: 1) a text analysis using computational linguistic methods for 13 500 posts from 45 expat platforms to find evidence of different kinds of social support based on the type of platform; 2) an online survey distributed to gather insights on expatriates’ types of participation and the types of social support they receive. We find that relations generated through virtual platforms – which we call platform contacts – are complementary sources for expatriates to obtain informational, emotional, and instrumental support, the latter two being higher for hybrid participants, i.e. for those who use online and offline features of the platform. This study further presents that expatriates who receive social support from platform contacts also show higher sustained participation, especially if they are hybrid participants. Based on these results, we present a dynamic model with testable propositions and discuss implications.

  • Yashar Bashirzadeh, Robert Mai, Corinne Faure (2021) How Rich is Too Rich? Visual Design Elements in Digital Marketing Communications. International Journal of Research in Marketing, Issue #1 Vol 39 (March 2022) pp 58 -76

Companies are increasingly including innovative visual design elements such as animations and pictographs in digital communication. While both elements can be beneficial in exchanges with their customers, we propose that combining them can have negative effects on communication effectiveness. Animations and pictographs enhance digital communication, essentially through increased perceptions of enrichment, but these elements also raise perceptions of clutter. As they enrich a message in unique ways, processing these different types of visual design elements requires distinct cognitive resources such that, when combined, clutter perceptions dominate the recipient’s perceptions and behaviors, thus paradoxically offsetting their positive effects. This interplay may not only undermine message outcomes but even spill over to downstream behavioral outcomes. In a large-scale randomized field experiment in cooperation with a mobile app company, we find that including animations (GIFs) and pictographs (emojis) together damages message outcomes (increasing unsubscriptions) and downstream outcomes (reducing in-app time) compared with what happens when these elements are deployed separately.We elaborate on the processing of the text and visual elements from this field experiment in two lab experiments, including an eye-tracking study. Finally, in two further online studies, we seek to establish whether the proposed mechanisms depend on the number of visuals or the types of pictographs employed.

We characterize the shape of spatial externalities in a continuous time and space differential game with transboundary pollution. We posit a realistic spatiotemporal law of motion for pollution (diffusion and advection), and tackle spatiotemporal non-cooperative (and cooperative) differential games. Precisely, we consider a circle partitioned into several states where a local authority decides autonomously about its investment, production and depollution strategies over time knowing that investment/production generates pollution, and pollution is transboundary. The time horizon is infinite. We allow for a rich set of geographic heterogeneities across states. We solveanalyticallythe induced non-cooperative differential game and characterize its long-term spatial distributions. In particular, we prove that there exist a Perfect Markov Equilibrium, unique among the class of the affine feedbacks. We further provide with a full exploration of the free riding problem and the associated border effect

In this paper, we study the role of narratives in stock markets with a particular focus on the relationship with the ongoing COVID-19 pandemic. The pandemic represents a natural setting for the development of viral financial market narratives. We thus treat the pandemic as a natural experiment on the relation between prevailing narratives and financial markets. We adopt natural language processing (NLP) on financial news to characterize the evolution of important narratives. Doing so, we reduce the high-dimensional narrative information to few interpretable and important features while avoiding over-fitting. In addition to the common features, we consider virality as a novel feature of narratives, inspired by Shiller (Am Econ Rev 107:967–1004, 2017). Our aim is to establish whether the prevailing narratives drive or are driven by stock market conditions. Focusing on the coronavirus narratives, we document some stylized facts about its evolution around a severe event-driven stock market decline. We find the pandemic-relevant narratives are influenced by stock market conditions and act as a cellar for brewing a perennial economic narrative. We successfully identified a perennial risk narrative, whose shock is followed by a severe market drop and a long-term increase of market volatility. In the out-of-sample test, this narrative went viral since the start of the global COVID-19 pandemic, when the pandemic-relevant narratives dominate news media, show negative sentiment and were more linked to “crisis” context. Our findings encourage the use of narratives to evaluate long-term market conditions and to early warn event-driven severe market declines.

In this paper, we examine the changes in the dependence structure of global stock markets amid the outbreak of COVID-19. We divide 56 stock markets into developed, emerging, and frontier markets and study their daily price data from 15 October 2019 to 17 August 2020 using the canonical vine (C-vine) copula approach. We observed significant changes in the dependence structure, the selection of the pair copula families, and the associated parameter estimates in the tree. In developed markets, during the COVID-19, the dependence of markets shifted from the Netherlands to France while the root node position of Hungary replaced the market of Poland. The frontier markets showed strong dependence signs with Mauritius before COVID-19 and Slovenia during the outbreak. Our findings are of interest to regulators and practitioners, particularly in monitoring the value at risk of portfolios and adopting appropriate strategies in light of the varying dynamics of stock markets during extreme events, such as COVID-19.

This paper analyzes the influence of small and medium-sized enterprises’ (SMEs) entrepreneurial orientation (EO) on its capacity to quickly introduce new products to the market (namely, speed to market). Specifically, we suggest that firms will exhibit greater speed to market when displaying either low or high levels of EO. We also suggest that the EO – speed to market relationship will be contingent on firms’ ambidexterity, or its capacity to simultaneously embrace exploratory and exploitative strategies. To test our hypotheses, we collected survey data from 384 SMEs belonging to four sectors in Spain: biotechnology, ceramic tiles, toys and footwear. Our findings confirm the existence of a U-shaped connection between EO and speed to market, and evidence that this curvilinear relationship is accentuated when SMEs exhibit greater ambidexterity.

firms, (2) is more realistic in terms of determination of weights, and (3) generates rankings for banks consistent with their credit ratings. We first use DEA to determine the efficient frontier and then estimate a common set of weights that can minimize the Euclidean distance between the firms and that frontier. This process is illustrated by a simple numerical example and is extended to a real-life situation using the Eurozone banking sector. Our ECSW approach outperforms other common set of weights approaches in both numerical and real-life examples, and in terms of providing rankings consistent with banks’ credit ratings.

This paper examines differences in bank efficiency between banks affiliated with single bank holding companies and those affiliated with multi-bank holding companies by applying a fuzzy multi-objective two-stage data envelopment analysis technique. Using a sample of U.S. commercial banks covering 1994–2018, the results show that banks affiliated with multi-bank holding companies are more efficient than those affiliated with single-bank holding companies, suggesting that the former takes advantage of their parents’ resources to enhance their efficiency, consistent with the internal capital market theory. They also show that banks with a powerful CEO exhibit lower efficiency than others. Moreover, there is an inverted U shape relationship between multi-bank holding company structure and bank efficiency, suggesting the presence of an optimal number of multi-bank holding subsidiaries that maximizes efficiency.

COVID-19 household transmissibility remains unclear in Pakistan. To understand the dynamics of Severe Acute Respiratory Syndrome Coronavirus disease epidemiology, this study estimated Secondary Attack Rate (SAR) among household and close contacts of index cases in Pakistan using a statistical transmission model. A retrospective cohort study was conducted using an inclusive contact tracing dataset from the provinces of Punjab and Khyber-Pakhtunkhwa to estimate SAR. We considered the probability of an infected person transmitting the infection to close contacts regardless of residential addresses. This means that close contacts were identified irrespective of their relationship with the index case. We assessed demographic determinants of COVID-19 infectivity and transmissibility. For this purpose based on evolving evidence, and as CDC recommends fully vaccinated people get tested 5–7 days after close contact with a person with suspected or confirmed COVID-19. Therefore we followed the same procedure in the close contacts for secondary infection. During the study period from 15th May 2020 to 15th Jan 2021, a total of 339 (33.9%) index cases were studied from 1000 cases initially notified. Among close contact groups (n = 739), households were identified with an assumed mean incubation period of 8.2+4.3 days and a maximum incubation period of 15 days. SAR estimated here is among the household contacts. 117 secondary cases from 739 household contacts, with SAR 11.1% (95% CI 9.0– 13.6). All together (240) SAR achieved was 32.48% (95% CI; 29.12–37.87) for symptomatic and confirmed cases. The potential risk factors for SAR identified here included; old age group (>45 years of age), male (gender), household members >5, and residency in urban areas and for index cases high age group. Overall local reproductive number (R) based on the observed household contact frequencies for index/primary cases was 0.9 (95% CI 0.47– 1.21) in Khyber Pakhtunkhwa and 1.3 (95% CI 0.73–1.56) in Punjab. SAR estimated here was high especially in the second phase of the COVID-19 pandemic in Pakistan. The results highlight the need to adopt rigorous preventive measures to cut the chain of viral transmission and prevent another wave of COVID-19



  • Maher A.N. Agi, Ashish Kumar Jha (2022) Blockchain technology for supply chain management: An integrated theoretical perspective of organizational adoption. International Journal of Production Economics, Volume 247, May 2022, 108458

Blockchain technology has been growing in importance and acceptability over the past few years. Yet, there is limited empirical research on the organizational and technology specific factors that play a critical role in driving its adoption in the supply chain. The purpose of this paper is to develop a comprehensive framework for blockchain adoption in the supply chain by identifying the enablers and empirically evaluating their interdependencies and impact on adoption. 20 enablers of blockchain adoption in the supply chain are identified using an extensive literature review and theoretical lenses from the Diffusion of Innovation (DOI) theory and the business technology adoption model developed by Iacovou, Benbassat and Dexter (1995). In the confirmatory phase, we employ the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method to extract logic from data collected from 37 French experts about the impact of the enablers and their interdependencies. Our paper extends the multi-theoretic empirical studies to blockchain technology and identifies the enablers of blockchain adoption from technological, organizational, supply chain and external environment perspectives. Regarding the importance of the categories of enablers, we find that the relative advantage of the technology and the external pressure are the most prominent categories of enablers that impact blockchain adoption in the supply chain. Our analysis also shows the important causal role on adoption of the potential of blockchain to reduce transaction cost, the consumer interest in traceability data and the establishment of a regulatory framework for blockchain usage

This study investigates whether waste management, including waste generation and recycling, affects firm performance. Using a panel of 14,601 firm-year observations from 41 countries from 2002 to 2019, we find a significantly negative (positive) relationship between waste generation (recycling) and firm performance. Our findings are robust to alternative measures of waste management and firm performance, sub-sample analysis, and alternative econometric specifications. Further, our results are robust to different identification strategies. Finally, our channel analysis shows that the negative (positive) relationship between waste generation (recycling) and firm performance is stronger in firms offering no environmental, social, and governance (ESG) based compensation. However, the relationship varies with the level of firms’ environmental orientation, and we observe insensitivity of the relationship regardless of firm-level governance quality. Our study presents important policy implications for regulators and firms

As perceived by company employees, luxury culture is best understood by collecting and analyzing anonymous genuine current or past employee-generated comments (EGCs) about their experience of specific work culture, without fear of retaliation by using digital platforms. This paper focuses on luxury culture, including organizational culture, founder culture, and country-of-origin culture. It examines the employee perception of organizational culture in the case of L’Oréal, a luxury cosmetics company, by analyzing EGCs collected from a digital platform. This study demonstrates that sentiment analysis methodology is a valuable technique in understanding how employees’ perceptions of luxury companies’ cultures and significantly that changes happening in luxury brands’ dynamic organizational cultures may well be known relatively early by analyzing the EGCs. This study adds a new factor to the luxury organizational culture called “digital culture,” in addition to the previously identified cultural determinants, including collective, emotional, historical, symbolic, dynamic, and diffuse dimensions

The purpose of this paper is to examine the current Brazilian scenario for resolving queries, the laws enacted and the participation of lawyers, including the studies they undertake in Brazilian law schools. This paper will focus on the extent of an ADR culture in Brazil analyzing the context of ADR’s in Southeastern Brazil (São Paulo, Rio de Janeiro, Espírito Santo and Minas Gerais) after the period of the validity in 2016 of the Brazilian Civil Procedure Code (Law No. 13.105/2015) calling for judicial1 mediation and stimulating ADR in Brazil up to 2017 (the year of data collection). An exploratory research was done. This study also seeks to 1) present the Southeastern Brazil data on the number of mediation sessions in order to identify the growth in the use of this method and 2) check the knowledge of Brazilian lawyers on the topic of ADR’s. A bibliographic and an archival research were carried out followed by three field researches using quantitative methods. The first research was implemented on a total of 621 lawyers who responded through a questionnaire with: two variables focused on individual characteristics of the respondent, five variables on the lawyer’s studies in negotiation/ADR, and ten variables on his/her professional activities. This questionnaire was designed to identify how lawyers actually negotiate and should serve to shatter the myth that adversarial bargaining is more effective and less risky than problem-solving. It is important to mention that some elements were adapted to the Brazilian culture. The second inquiry was conducted on a total of 397 lawsuits forwarded to business mediation in Rio de Janeiro court from 2016 (91 lawsuits) through 2017 (306 lawsuits). The variables of this research were completely different from the lawyers’ questionnaire. In this one, there were 6 variables on the characteristics of lawsuits and 8 variables on the agreement settled. The third study was also done in this court on a total of 270 lawsuits. This sampling was obtained at the center dedicated to the study of the judiciary at Fundação Getulio Vargas (FGV) that is responsible for doing CNJ’s (National Counsel of Justice) reports, such as Supreme in Numbers—this report analyzes the processes in Brazilian Superior Court and Justice in Numbers. The research focused on agreements settled directly by parties without mediation. However, in this group, the data is compiled by sampling. During the study period of this thesis, 2700 lawsuits were initiated. FGV, using the software language MySQL, randomized 270 lawsuits (10%) which were analyzed by the author of this thesis based on the same elements and the previous inquiry. The analysis provided results on how ADR has been developed in Brazil. The possibility for generalizations has been confirmed for both inside and outside the courts. There is a movement for culture change and greater adoption of ADRs in Brazil. However, the paradigm shift has not yet been fully realized. The Brazilian Civil Procedure Code (Law No. 13.105/2015) calling for judicial mediation and stimulating ADR in Brazil increased the number of judicial mediation sessions. Lawyers are not familiar with the adoption of ADR as problem-solving and their acting is not seen as collaborative. This generalized performance measurement can be used in future research and for professional purposes in the ADR environment. The study also presents a comparison of business mediation done inside and outside courts

Medical tourism is a recent term in healthcare logistics referring to travel of patients to receive health services and spending leisure time in a destination country. This transferring of patients leads to access high-quality health services which are cheaper than the original country of patients. During this travel, passengers who are the patients from another country, have this opportunity for complimentary entertainment packages (e.g., pleasure tours) in the aftercare period. As far as we know, the term of medical tourism is rarely studied in healthcare logistics and such services are highly important for developing countries. Such facts motivate us to develop a practical optimization model for the Medical Tour Centers (MTCs) for allocation of patients to hospitals in proper time and creation of memorable aftercare time for them. In this regard, the main aim of the proposed model is to maximize the total profit of MTCs through optimal allocation of patients to hospitals while considering an aftercare tour for the passengers. To make the proposed model more realistic, the optimal residence time in attractive places is simulated by a time-dependent gravity function. To address the uncertainty of medical tourism problem, a scenario-based two-stage stochastic optimization approach is extended to encounter different sources of uncertainty existing in surgical success, medical time, restoration restrictions, and the attraction of tourist places. Another novelty of this work is to propose an innovative hybrid meta-heuristic for large-scale instances, which is a combination of Progressive Hedging Algorithm (PHA) and Genetic Algorithm (GA). The model is analyzed by different test problems for small, medium, and large-scale instances where the hybrid meta-heuristic algorithm could solve them with an average gap of 3.4% in comparison with the commercial solver. The results revealed the importance of tourist opinion and public preferences in medical and pleasure tours, respectively, to improve the economic growth in this sector in developing countries

Recent market studies showed that the demand for organic and local agrifood products is increasing despite their higher prices. The agribusiness actors should therefore rethink the supply chain configuration to cope with new market trends characterized by the rise of the organic segment and the increase of consumers’ preference to more local products. This study focuses on the olive oil sector and proposes a mixed-integer non-linear optimization model for the design of olive oil supply chains while incorporating organic and conventional market segments and considering, for each segment, a supply chain proximity- and price-sensitive demand. The model is developed with the collaboration of olive oil producers in the Mediterranean area. Thanks to this industrial collaboration, we account for real-world practices and constraints and apply the model to a realistic case study. We first linearize the model and show that it can be efficiently solved with commercial optimization softwares. Based on numerical experiments, we derive a series of managerial insights that are applicable to the considered case study, some of them are not intuitive. For instance, we show that an increase in consumers’ preference to more local products may lead the producer to offer products with a more global supply chain. The conventional product variety may be produced with a more local supply chain than the organic (premium) variety. Finally, offering a mix of organic and conventional varieties instead of only one variety would lead to implementing a more local supply chain.

We identify the core topics of research applying machine learning to finance. We use a probabilistic topic modeling approach to make sense of this diverse body of research spanning across multiple disciplines. Through a latent Dirichlet allocation topic modeling technique, we extract 15 coherent research topics that are the focus of 5942 academic studies from 1990 to 2020. We find that these topics can be grouped into four categories: Priceforecasting techniques, financial markets analysis, risk forecasting and financial perspectives. We first describe and structure these topics and then further show how the topic focus has evolved over the last three decades. A notable trend we find is the emergence of text‐based machine learning, for example, for sentiment analysis, in recent years. Our study thus provides a structured topography for finance researchers seeking to integrate machine learning research approaches in their exploration of finance phenomena. We also showcase the benefits to finance researchers of the method of probabilistic modeling of topics for deep comprehension of a body of literature.

  • Macpherson A, Breslin D, Akinci C. (2022) Organizational Learning From Hidden Improvisation. Organization Studies. Vol. 43(6) 861–883

Research has identified improvisation as a creative and open activity that can be harnessed to encourage innovation and learning within the organization. In this paper, we present improvisation as a covert phenomenon, occurring in a climate of mistrust and fear of censure, and disconnected with wider organizational learning. Drawing on qualitative evidence of a Fire Service in the United Kingdom, we explore hidden improvisation, and identify the conditions and processes that can connect these local deviations to wider processes of learning. We show that while most improvisations remain hidden and contained to avoid wider scrutiny, certain conditions of frequency, connectedness and scale escalate events to become more visible to supervisors and managers. The learning outcomes from these visible improvisations will then depend on management’s interpretation, evaluation and translation of improvising behaviours. Dependent on prior relationships of trust and credibility, middle management perform a key brokering role in this process, connecting previously hidden improvisation to wider organizational systems and structures

  • Clarke, R., Richter, A. W., & Kilduff, M. (2022). One tie to capture advice and friendship: Leader multiplex centrality effects on team performance change. Journal of Applied Psychology. 107(6), 968–986

Because leaders’ authority is often insufficient to change team performance, formal team leaders seek informal influence through the occupation of central positions in social networks. Prior research focuses on leader centrality involving simplex ties, that is, either friendship or advice, to the neglect of multiplex ties that involve the overlap of friendship and advice. Friendship and advice ties offer different but complementary resources, so leader centrality in one but not the other network limits leader influence. We provide theory and evidence concerning how leader multiplex centrality affects team performance improvement, particularly if leaders are embedded in team social contexts with sparse friendship and numerous adversarial ties. The research context involved 84 ongoing public university service teams headed by formal leaders. Our results show the importance of leader multiplex centrality relative to leader simplex centrality. First, leader multiplex centrality predicted team performance change over a 2-year period more strongly than leader centrality in either the advice or the friendship team network. Second, leader multiplex centrality positively predicted team performance change for teams featuring dense adversarial networks or sparse friendship networks. It is not sufficient, therefore, for leaders to be either liked or regarded as expert. It is the integration of both advice and friendship in one tie between the leader and followers that facilitates performance change.

We investigate the impact of acquiring similar or complementary technologies on the innovation performance of Chinese multinationals’ strategic asset-seeking M&As in the EU, and whether such impact is contingent upon firm-level and region-level technological gaps. Results show that technological complementarity enhances Chinese multinationals’ innovation performance. Firm-level technological gaps have a positive moderating effect for both complementary and similar technologies. Region-level gaps enhance innovation when Chinese firms acquire similar technologies, but they undermine the positive impact of technological complementarity on innovation performance. We advance understanding of Chinese MNEs’ learning scope and strategic intents in their strategic asset-seeking M&As.

This study addresses one of the most challenging issues in designing a sustainable and efficient ride-sharing service. This paper uses an extensive computational study to quantify the behavior of carpooling in customized bus routing problems. This mechanism allows organizations to draw on the potential of their employees’ private cars to provide convenient alternative rides for other employees, thereby reducing air pollution and greenhouse gas emissions as well as increasing overall satisfaction with the transportation system offered. The objective functions minimize: (i) total transportation costs and incentives paid to drivers of private cars, (ii) dissatisfaction as determined by staff walking distance, travel time, and delays in arriving at work, and (iii) total carbon emissions generated by commuting. We propose a resolution algorithm based on Pareto Strength Ant Colony Optimization (PSACO) as an effective meta-heuristic method for solving the multi-objective mathematical model and compare it with the results obtained by an exact method. The effectiveness and applicability of the proposed problem have been evaluated by performing computational experiments on a real case study in Paris using a number of comparative metrics with appropriate assumptions. Different parameters affecting the performance of the algorithm are also investigated. The concluding section presents a comparison of the results achieved. The test outcomes confirm that the formulation and the solution methods can be useful references for practice. The insights obtained from the research could provide the basis for designing incentive schemes and information campaigns aimed at making ride-sharing systems more successful and improving their performance.

In this perspective piece, we aim to broaden understanding of business model innovation (BMI) by expanding and deepening extant theoretical dimensions and positions in the literature. While a significant amount of research has been carried out on the phenomenon of BMI, the current theory does not fully capture the broad diversity and inherent implications of the various approaches taken. We address this lack of common ground by developing an organizing framework for BMI research. To do so, we first delineate the business model (BM) concept’s multifaceted properties that provide the foundation for theorizing BMI. Using topical identification, we then situate and substantiate a range of theoretical lenses within strategy, innovation, and entrepreneurship, as three central research axes informing studies on BMI. By revealing the relevant research perspectives, theoretical lenses, and positioning choices in the framework, our work expands and further details the conceptualization of BMI and provides orientation for future studies in the field.

The results show that Chinese companies operating in better institutional environments have higher CSR disclosure. Moreover, the type of the ultimate controller of a company is significantly related to the level of CSR disclosure, which is higher in state-controlled companies than in nonstate-controlled companies. The results are robust to different proxies of CSR disclosure

This study examines how debtholders perceive accounting information quality of firms with audit committee members who are also on the remuneration committee, and whether strong CEO power enhances or undermines the governance role of overlapping committees. Using 841 observations of Malaysian firms over the period 2013–2015, we find that firms with overlapping audit and remuneration committees are perceived by debtholders to be transparent and of lower operating risk and, consequently, be associated with lower cost of debt. We also find that the beneficial effect of the presence of overlapping committees is weakened by the level of CEO power. Our results are robust to concerns of endogeneity and alternative measurers of the key variables. This study is timely in light of recently increasing call for the broadening of audit committee members’ understanding of business strategies, risks and incentives provided by firms’ executive compensation structures. Our study also contributes to the ongoing debate surrounding CEO power by suggesting that debtholders perceive potent CEO power as detrimental to their investments and thus charge higher interest rates from firms with powerful CEOs and overlapping directors

The literature on Mergers and Acquisitions (M&A), cultural differences between organizations have frequently been identified as one of the main challenges in the process of post-merger integration (PMI). Existing research has explored a broad variety of cultural differences in perceptions, such as those relating to expectations, norms, values and beliefs within the respective organizations, and how these affect the process and success of PMI. However, less attention has been paid to the relevance of the macro-societal context to PMI. The ambition of this article is, therefore, to advance our understanding of how macro-level societal factors define organizational cultures and affect the success of PMI. We draw on social systems theory as devised by Niklas Luhmann, assuming that organizations are always embedded in the macro-level societal context of distinctive realms of social reality—such as the economy, politics, religion and the arts—that make up the so-called “function systems”. Looking at the case of the integration of a Brazilian technology start-up into a market-leading corporation, we analyze the dominant orientations towards these function systems, and the changes in these orientations over time. The results suggest that differences in organizational culture in PMI can be partly explained by differences in orientations to the function systems. Moreover, forcing dramatic changes of orientations towards the function systems within a merged entity can severely damage its raison d’etre in the first place, potentially leading to, in some sense, an account of “culture murder”. This article is unique in demonstrating that organizations are multifunctional systems whose culture is defined by the highly specific and potentially varying degrees of importance they place on individual function systems and that knowledge or neglect of these functional profiles may seriously affect the success of post-merger integration. Against this backdrop, the article presents a multifunctional profiling method that may easily translate into PMI management tools

We document short-run changes in websites and the web technology industry with the introduction of the European General Data Protection Regulation (GDPR).We follow more than 110,000 websites and their third-party HTTP requests for 12 months before and 6 months after the GDPR became effective and show that websites substantially reduced their interactions with web technology providers. Importantly, this also holds for websites not legally bound by the GDPR. These changes are especially pronounced among less popular websites and regarding the collection of personal data. We document an increase in market concentration in web technology services after the introduction of the GDPR: Although all firms suffer losses, the largest vendor—Google—loses relatively less and significantly increases market share in important markets such as advertising and analytics. Our findings contribute to the discussion on how regulating privacy, artificial intelligence and other areas of data governance relate to data minimization, regulatory competition, and market structure

A key premise in innovation literature suggests that individuals enabling contact between pairs of otherwise disconnected others (i.e., holding open triads) are more innovative, as they benefit from more opportunities for knowledge recombination. Such benefits also come with a cost, as conducting innovative action from open triads requires finding common ground to coordinate and integrate disparate knowledge and efforts from unconnected others. However, it is yet unclear which specific open triadic structures offer the greatest net value to facilitate individual innovativeness. We contribute to this debate by going beyond a homogeneous conceptualization of open triads, examining the relation between different brokerage roles and individual innovativeness. We theorize that some roles are more balanced than others in terms of access to knowledge novelty and integration costs. Specifically, we find that balanced open triads (gatekeepers and itinerant roles) are crucial to facilitate individual innovativeness, as compared to unbalanced open triads (coordinator and liaison roles). We also propose that brokers obtain the greatest innovation benefits from balanced open triads when they are embedded in institutional settings that are distant from knowledge applicability. We test our ideas through a large-scale study of 1,010 biomedical scientists

Taking an inductive approach, this paper explores a key question with respect to tourists’ meaning creation: What is the role of servicescapes in the development of place meanings for tourists? The research is situated in place and appropriation theory and leverages a large two-phase qualitative study on tourists’ restaurant experiences in Brittany, an important tourism destination in the North-West of France. Analysis of the narrative data uncovers four dimensions of restaurant servicescapes that contribute to place meaning. These are: The Interior Environment; The Service Offer; The Social Environment, and the Restaurant Exterior. Furthermore, the research provides insights into the ways tourists connect servicescapes to destinations through physical and sensorial immersion, investigation, and learning. This research can help practioners in creating more meaningful holiday experiences and in branding and promoting tourism destinations. It opens the way for the exploration of the role other tourism services in the development of meaningful tourism experiences.

Climate change discourse integrates 3Ps – people, planet, and profit. However, we do not find any empirical study that integrates 3Ps. Therefore, using a large global panel dataset from 46 countries, this study intends to fill this gap by providing empirical evidence about investors’ value proposition of corporate climate performance in different cultural environments. The results show that Hofstede’s cultural dimensions affect corporate climate performance and its market pricing. We find that in cultures with high power distance, low individualism, high masculinity, high uncertainty avoidance, high long-term orientation, and high restraint, the investors generally penalize the firms disclosing higher environmental performance. Strangely enough, corporate waste production is universally value irrelevant. Our results indicate some policy implications.

This study explores a new methodology called community-aided brand concept map (CA-BCM) for eliciting brand association networks using data collected from technology-enabled online communities. NVivo software is used to qualitatively code these data to 1) uncover how users associate themselves with a brand and 2) use content analysis to quantify each of these associations, leading to the elicitation of a comprehensive network of brand associations and their relationships. Using the example of a movie brand, the new tool CA-BCM effectively uncovers 1) the core, secondary, and tertiary brand associations and 2) classifies the brand associations into strong, favorable, and unique associations. Finally, 3) using these brand association classification data and the brand awareness level, customer brand equity is measured. Pearson correlation is used to provide external validity to the CA-BCM technique, which shows a significant and positive relationship between customer brand equity and market performance. The implications and limitations of this study are presented

To promote manufacturing transformation and upgrading, this paper proposes a comprehensive analytical framework for manufacturing development from an industrial network perspective. We explore the organizational structure of the manufacturing association network based on the industrial network analysis technique and the modern network analysis technique. A new data envelopment analysis (DEA) model, which considers the interrelated and interactive characteristics of various sectors, is used to evaluate the static and dynamic performance of manufacturing sectors combining the Malmquist productivity index (MLI). We adopt this framework to analyze the development of 18 manufacturing sectors in Hubei Province, China, during the 2012–2017 period. Key development sectors play a critical role in the stability and development of the manufacturing system, yet their performance did not show significant improvement during this timeframe. During the implementation of the Made in China 2025 strategy, most sectors followed the transformation path by enhancing technological strength first and technological application capabilities later. The manufacturing industry in Hubei Province suffers from insufficient informatization construction and slow productivity improvement.

This paper aims to test the impact of negotiation power between auditors and audited companies, in relation to audit fees. The study found that there is a significant positive relationship between auditors’ power of negotiation and the audit fees. In addition, it found that there is a significant negative relationship between the size of the audited companies, their negotiating power and the audit fees. These findings indicate that when companies negotiate with Big4 audit firms, their bargaining power does not have a significant effect on the audit fees. Nevertheless, if the auditor is not one of the Big4, there is a significantly negative relationship between the company’s bargaining power and audit fees. The relationship therefore changes according to the size of a company. If a company is large, there will be a negative relationship with the audit fees. However, if it is a small company, the relationship is not significant.

A delivery mix that includes delivery from stock and drop-shipping is of interest to many internet re- tailers. We consider a retailer serving a time- and price-sensitive market with two substitutable products that differ in the guaranteed delivery time and price, an express product (delivered from the stock) and a regular product (drop-shipped). In case of stockout, customers may switch from the express product to the regular product. We study how to differentiate the products in terms of delivery times and prices and how to determine the stock level to maximize the retailer’s expected profit while satisfying ser- vice constraints. We solve different variants of the problem and derive insights into the optimal retailer’s strategy. In addition, we study the impact of stockout-based substitution. This paper is the first to investigate time- and price-based differentiation along with inventory decisions for a retailer who relies on a hybrid distribution to satisfy a time- and price-sensitive demand subject to stockout-based substitution. When prices and stock are fixed, in addition to minimum and maximum time differentiations, a medium differentiation strategy may be optimal but depends on the stock level. When only prices are fixed, there exists a price differentiation limit below which a minimum time differentiation is optimal, and above which only the express product should be offered. For the general model, numerical experiments show that a higher stockout-based substitution leads to greater time differentiation (which is consistent with the results of previous models) and more stock. However, this would not impact the price differentiation

Adjusting to China competition: Evidence from Japanese plant-product-level data.Review of International Economics, Volume30, Issue3, Special Issue: Globalisation: Implications for workers, firms and markets, August 2022, Pages 732-763

This study examines how the product mixes of Japanese manufacturing plants have been impacted by the rise of China imports over the period 1997– 2014. It focuses on the way plants are embedded in their local environment mitigates this causal relationship. We find evidence that China import competition induced both product down-sizing and product exit within Japanese manufacturing plants. Moreover, we find that those negative effects dif-fer across plants according to various plant character-istics including the spatial organization of their parent firm, and the degree of their exposure to external ag-glomeration economies.

The cognitive perspective in entrepreneurship research has predominantly evolved around the static conceptions of cognition at the level of individual reasoning. Recently, the emerging stream of situated entrepreneurial cognition asserts that the environment substantially influences the inherent knowledge structures of entrepreneurial reasoning. It claims that the context indoctrinates the perceptions and beliefs underlying decision making, thus authoring entrepreneurial cognition to derive from the recursive interaction between the mind and the respective environment. Drawing on this perspective, this article follows a narrative approach investigating the unfolding dynamics between the entrepreneurial cognition and contextual factors in a business model design. Using textual accounts from 34 episodic interviews with entrepreneurs from corporate entrepreneurship initiatives, we applied a constant comparative method identifying main themes in the data. Our findings show that entrepreneurial cognition is embedded, grounded, and distributed. We provide evidence that the situated entrepreneurial cognition results from the recursive interplay of material objects, bodily interactions, and agents spanning a social system. Our findings suggest that the unilateral consideration of authored cognitive systems falls short in capturing the holistic nature of entrepreneurial cognition. Thus, our findings further empirically ground situated entrepreneurial cognition by placing the entrepreneur at the nexus of individual and context. Finally, this article reveals the business model as a central boundary object connecting and focalizing a variety of influences on the situated entrepreneurial cognition in its social context.



  • Ammar Ali Gull, Muhammad Atif, Tanveer Ahsan, Imen Derouiche (2022) Does waste management affect firm performance? International evidence. Economic Modelling, volume 114, 105932

This study examines an important yet underexplored aspect of firms’ sustainability practices, i.e., waste management, in order to analyze its impact on financial performance. Although the extant literature has focused on various aspects of sustainability, the impact of waste management, which has disastrous consequences for the climate and firm performance, remains largely unexplored. Thus, using the 2002–2019 data of listed firms from 41 countries, we found a significantly negative (positive) relationship between waste generation (recycling) and financial performance. Our findings are robust to alternative variables, sub-sample analysis, and identification strategies. Moreover, a channel analysis showed that this relationship is influenced by operating costs, ESG performance-based compensation, industry nature, the Paris agreement on climate change, and the global financial crisis. Overall, the findings suggest that environmental initiatives are beneficial for firms and present important policy implications for regulators and firms.

This study addresses one of the most challenging issues in designing a sustainable and efficient ride-sharing service. This paper uses an extensive computational study to quantify the behavior of carpooling in customized bus routing problems. This mechanism allows organizations to draw on the potential of their employees’ private cars to provide convenient alternative rides for other employees, thereby reducing air pollution and greenhouse gas emissions as well as increasing overall satisfaction with the transportation system offered. The objective functions minimize: (i) total transportation costs and incentives paid to drivers of private cars, (ii) dissatisfaction as determined by staff walking distance, travel time, and delays in arriving at work, and (iii) total carbon emissions generated by commuting. We propose a resolution algorithm based on Pareto Strength Ant Colony Optimization (PSACO) as an effective meta-heuristic method for solving the multi-objective mathematical model and compare it with the results obtained by an exact method. The effectiveness and applicability of the proposed problem have been evaluated by performing computational experiments on a real case study in Paris using a number of comparative metrics with appropriate assumptions. Different parameters affecting the performance of the algorithm are also investigated. The concluding section presents a comparison of the results achieved. The test outcomes confirm that the formulation and the solution methods can be useful references for practice. The insights obtained from the research could provide the basis for designing incentive schemes and information campaigns aimed at making ride-sharing systems more successful and improving their performance

This study reviewed the artificial intelligence (AI) and machine learning (ML) literature in the finance field. Using a bibliometric approach, we collected 348 articles published in 2011–2021 from journals indexed in the Scopus database. Multiple software (RStudio, VOSviewer, and Excel) were employed to analyze the data and depict the most active scientific actors in terms of countries, institutions, sources, documents, and authors. Our review revealed an upward trajectory in the publication trend starting from 2015 and found the application of AI and ML in bankruptcy prediction, stock price prediction, portfolio management, oil price prediction, anti-money laundering, behavioral finance, big data analytics, and blockchain. Moreover, the United States, China, and the United Kingdom were the top three contributors to the literature. Our results provide practical guidance to market participants, especially, fintech and finance companies, on how AI and ML can be used in their decision-making

This study examines the role of emotions and empowerment in the destigmatisation of disability. We draw on 12 in-depth interviews with professional disabled athletes and a netnography study of 221 YouTube comments from consumers of disability sport advertising. The findings show that both athletes and consumers share their own emotions or report on their perception of others’ emotions to mutually empower themselves and each other, which reduces stigma related to disability. By integrating the literatures on stigma, emotions and empowerment, we reveal how consumers of advertising contribute to the destigmatisation of others’ devalued social identities. Theoretical and practical implications of the findings related to advertising and inclusion are discussed.



  • Narjes Kandil, Ramzi Hammami, Olga Battaïa (2022) Insourcing versus outsourcing decision under environmental considerations and different contract arrangements, International Journal of Production Economics, Volume 253, 2022, 108589

We investigate the insourcing versus outsourcing decision for a manufacturer, facing a price- and carbon emission-sensitive demand and an environmental regulation in the form of a carbon tax. We consider the carbon emissions generated during the production phase. In case of outsourcing, the transportation emissions are also considered, and we investigate the outcomes of revenue sharing and cost sharing contracts between the manufacturer and the supplier. We study the impacts of customers’ environmental  awareness, carbon tax, price sensitivity, market potential, and supplier’s location on the insourcing vs. outsourcing decision, the environmental performance and the selling price. Our results show that a higher customers’ environmental awareness, a larger market potential and a longer distance between the supplier and the manufacturer favor insourcing over outsourcing, whereas a higher carbon tax and a higher price sensitivity favor outsourcing.

Dilemmas related to the use of environmental resources concern diverse populations at local or global scales. Frequently, individuals are unable to visualize the consequences of their actions, where they belong in the decision-making line, and have no information about past choices or the time horizon. We design a new one-shot extraction game to capture these dynamic decisions. We present results from a nationwide common pool resource experiment, conducted simultaneously in eleven French cities, involving a total of 2813 participants. We examine, for the first time, the simultaneous impact of several variables on the amount of resource extracted: the local vs. the national scale of the resource, the size of the group (small vs. big), the low vs. high recovery rate of the resource, and the available information. We show that individuals significantly reduce extraction levels in local as compared to national level dilemmas and that providing recommendations on sustainable extraction amounts significantly improves the sustainability of the resource. Overall, women extract significantly less, but care more about preserving the local resource; older participants extract significantly more resources but extract less from the national resource. Our experiment also fulfills a science popularization pedagogical aim, which we discuss.

Several machine learning techniques and hybrid architectures for predicting bitcoin price movement have been presented in the past. Our paper proposes a hybrid model encompassing classification and regression models for predicting bitcoin prices. Our analysis found that the automated feature interactions learner (deep cross networks) error performance using a plethora of technical indicators, including crypto-specific technical indicator difficulty ribbon compression and control variables such as Metcalfe’s value of bitcoin, number of unique active addresses, bitcoin network hash rate, and S&P 500 log returns, in a hybrid architecture is better than the single-stage architecture. The hybrid model predicted a 100% directional hit rate and maintained steady volatility in returns for the out-of-sample period. Our paper concludes that in terms of risk (Sharpe ratio 1.03) and profitability (260% and 82%), the hybrid model’s bitcoin futures strategy performed better than the deep cross network regression and buy-and-hold benchmark strategies.

Human accomplishments have increased the complexity and interconnectedness of environmental threats, resulting in widespread effects on people, ecosystems, and economies worldwide. In addition to overpopulation, pollution, burning fossil fuels, and deforestation, humans also impact the physical environment in many ways. These changes have contributed to climate change, soil erosion, poor air quality, and undrinkable water. We investigate the linear and non-linear effects of natural resources and education on CO2 emissions in the Latin American (LA) group of nations considering the roles of green energy, foreign remittances, and economic growth from 1990 to 2020. We have developed a comprehensive empirical analysis that applied second-generation advanced econometric methodologies in this study. The results of this research disclosed that natural resources pose a non-linear impact on environmental quality. The low level of natural resources benefits the environment in the LA panel, but higher use of natural resources ultimately intensifies CO2 emissions. Hence, a U-shaped association between natural resources and CO2 emissions is found in the LA panel. In the linear model, natural resources also boost CO2 emissions. Alongside this, education also intensifies CO2 emissions in the selected sample. Green energy and remittances mitigate CO2 emissions and thereby improve environmental quality.

Supplier reliability is a critical issue for manufacturing companies. Delivery delays from suppliers create backlog and firefighting on the shop floors. To avoid disruption and hedge against supplier lead time un- certainty, companies rely on diversification, multi-sourcing, and safety lead times. In multi-sourcing, the buyer might order the same product (raw material) from different suppliers. The design of a robust and cost-efficient purchasing/ordering plan in multi-sourcing is a complex task which has a strong impact on the performance of the company. In this study, we investigate the use of robust optimization for the integrated lot-sizing and supplier selection problem under lead time uncertainty. More specifically, we use polyhedral budgeted uncertainty sets. The resulting model determines the ideal lot sizes to minimize the total costs taking into consideration suppliers’ reliability and prices. To solve this problem, a row and column generation approach is proposed. To alleviate scalability issues, we enhance the row and column generation through a robust counterpart formulation, and we propose an efficient fix-and-optimize ap- proach. Our extensive computational experiments show that the fix-and-optimize approach yields good quality solutions within a reasonable amount of computational time. We provide insights into supplier diversification based on the risk profile of the decision-maker. One of the conclusions is that an extremely risk-averse decision-maker selects a single supplier, namely the most reliable one even if it does not offer the lowest price.

As energy overuse and generated pollution have a potential threat to our environmental and ecological conditions, many researchers have taken the initiative way to join the green campaign to prevent more damage to the environment. This paper investigates the main contributions related to the green vehicle routing problem (Green- VRP) and presents a classification scheme based on its variants considered in scientific literature, in particular, three major and applicable streams including internal combustion engine vehicles (ICEVs), alternative-fuel powered vehicles (AFVs), and hybrid electric vehicles (HEVs), and also several sub-categories for each of them. This systematic literature review intends to provide a comprehensive and structured survey of the state of knowledge and discuss the most important characteristics of the problems, including techniques of formulation, solution methodologies, and areas of application. This paper presents different analytical summary tables for each variant to emphasize some main features that provide the direction of the development of researches. Finally, to spot future avenues, gaps in the literature are distinguished to illustrate how new contributions are different from traditional problems

Policy uncertainty (PU), and sustainability disclosure, influence the performance of the firms. We use European data to extend the nascent literature on sustainability disclosure, and economic policy uncertainty by investigating the moderating impact of sustainability disclosure on the relationship between economic policy uncertainty and firm performance. We find overwhelming evidence that policy uncertainty reduces firm performance; however, sustainability disclosure moderates this destructing impact of policy uncertainty on firm performance. Our results show that environmental and social disclosure by the European firms enhances their reputation and help these firms in reducing the policy-induced uncertainty. A higher governance disclosure representing efficient corporate governance also help European firms to moderate the negative effect of policy uncertainty on their performance. Our results are robust to alternate proxies of firm performance as well as endogeneity issues.

  • Yann Truong, Hamid Mazloomi, Pascual Berrone.(2021) Understanding the Impact of Symbolic and Substantive Environmental Actions on Organizational Reputation. Industrial Marketing Management. 92 (2021) 307–320

Research in corporate environmental practices has shown that stakeholders impose coercive and normative forces that drive firms to perform environmental protection actions. However, limited attention has been placed on how different constituents of stakeholders value the firm’s environmental actions. By focusing on industry peers as a constituent of stakeholders, we examine how the firm’s environmental actions impact its reputation. Based on institutional theory and signaling theory we propose that symbolic environmental actions negatively affect reputation, whereas substantive actions improve firm’s reputation among its peers. Building on the notion of signaling process, the authors also observe that a firm’s reporting practices moderate positively the negative effect of symbolic actions. Data from a sample of 213 publicly traded firms operating in polluting industries from 2006 to 2013 support these results. The findings emphasize the danger of using symbolic actions to signal environmental commitment in a context of high-involvement information search and opportunistic behaviors.

We demonstrate the benefit to economics of machine learning approaches for textual analysis. Our use case is a machine learning based structuring of research on computational economics based on 1160 articles published in the Computational Economics journal from 1993 to 2019. Our Latent Dirichlet Allocation approach, popular in the computer sciences, use a probabilistic approach to identify shared topics across a body of documents. This combines natural language processing of article content with probabilistic learning of the latent (hidden) topics that link groups of articles. We show that this body of research can be well-described by 18 overall topics and provide a structure for computational economists to adopt this approach in other avenues.

Emerging country firms have been increasingly engaging in cross-border mergers and acquisitions, and these acquirers predominantly acquire firms from developed countries. The motivation for such acquisitions is to achieve market access but also to benefit from transfers of cross-border managerial skills and knowledge. The performance of such acquisitions has started to receive some research attention, particularly financial performance, but the transfers to other areas such as marketing have not yet been explored. This article addresses this gap by studying the experience of 34 acquirers from emerging countries which acquired firms in developed countries. This study uses two-stage window data envelopment analysis (DEA) and Tobit regression to investigate the impact of these acquisitions on the marketing capability and overall firm performance of the acquiring firms. The results show that the marketing capability of the acquiring firms did improve in the post-merger years and this improvement can be partly attributed to the acquisition. The findings also show that the overall performance of the acquiring firms improved following acquisition, but this is a continuation of superior performance from the pre-merger years rather than a synergistic gain from the acquisitions.

In order to implement or maintain a green supply chain (GSC) that produces goods and services responsibly and sustainably, supply chain managers should use tools that allow for the efficient identification, quantification, and mitigation of the ever-present risks. The objective of the present research is to identify the risk factors associated with the processes involved in GSC management. Based on an analysis of the characteristics of GSC risk, the authors put forward a list of risk design principles and a risk criteria evaluation system for a GSC. Gray relation analysis method was then used to clarify the degree of connection between certain supply chain risk factors and select key risk factors. Finally, Back Propagation Artificial Neural Network (BP-ANN) method was used to determine the risk level associated with a GSC. The determination of risk level will help companies to develop effective strategic management initiatives in a GSC environment.

Applying probabilistic utility approach with different algorithms and time horizons, we find that addition of cryptocurrencies to traditional stock portfolios adds value in terms of enhancing returns. This is consistent with the growing literature on the hedging properties of cryptocurrencies against traditional financial assets.

The purpose of this study is to investigate themoderating impact of corporate governance (CG) on the relationship between economic policy uncertainty (EPU) and the sustainable growth (SG) ofChinese firms. The study collects data of 975 Chinese non-financial listed firms for the period from 2010 to 2017. The study measures SG using a comprehensive index based on nine financial indicators and applies industry and year fixed effects regression to investigate the direct and moderating impact ofCG on the relationship between EPU and SG of Chinese firms. The results of the study explain that EPU negatively affects SG, while concentrated ownership, board independence and board gender diversity (BGD) positively contribute to the SG of the Chinese firms. The results also explain that concentrated ownership and BGD reduce the negative impact of EPU on the SG of the Chinese firms. The study considers only non-financial firms; therefore, the results of this study cannot be generalized for financial firms. Future research can be carried out while considering financial firms as a unit of analysis. The investigation of the negative impact of policy uncertainty on SG is essential for the government and policymakers to devise policies to reduce uncertainty. The investigation of the moderating effect of CG enriches the literature on corporates’ response to policy uncertainty. It provides valuable insights for corporates regarding CGmechanisms to attain SG. To the best of the authors’ knowledge, this is the first study that investigates the moderating impact ofCG on the SG of Chinese firms using an index-basedmeasurement of SG.

Unbalanced assembly line research has grown in importance because of its increasing applications in emerging economies, reverse logistics and remanufacturing. This paper examines the performance of numerous simulated patterns for reliable unbalanced manual merging assembly lines. The contribution of this study to the literature is that imbalance does not always negatively impact efficiency and that it can improve merging line performance when compared to a corresponding balanced merging line. The best performance was found to be a balanced line configuration and a monotone decreasing order for both parallel merging lines, with the former generally resulting in a lower throughput and the latter resulting in a lower average buffer level than that of a balanced line.

Trade intensity, economic downturns, and negative net equity capital outflows positively influence dynamic conditional correlations between South Asian and US/Chinese financial stock returns. Chinese and US financial firms transmitted more spillovers than they received during the global financial crisis. Results are robust to the use of USD or local currency returns, and the alternative specification of the Diebold–Yilmaz model.

The emergence of the sharing economy has had a tremendous impact on the tourism industry; however, few quality management mechanisms exist for shared tourism services. Based on unique data of 52,248 transactions collected from BlaBlaCar, the world’s leading ridesharing platform, this study examines the independent and combined effects of quality cues on travelers’ demand for peer-to-peer ridesharing services. The findings suggest that intrinsic cues (product reputation and seller reputation) and extrinsic cues (relative price and offer duration) are decisive in increasing demand, and their combined effects can be positive or negative. In addition, analyses of the heterogeneous effects of intrinsic and extrinsic cues across seller segments clarify how consumers evaluate product quality using information from multiple cues. These findings contribute to the literature on tourism and marketing by providing new insights into the design of competitive product offers in the sharing economy.

This paper seeks to expand our understanding of sustainable entrepreneurial ecosystems by investigating the interrelation between contextual factors and sustainable entrepreneurial activities of sharing ventures. While the sharing economy is considered as a potential pathway to a more sustainable society,; ambiguous activities of some sharing ventures call the credibility of sharing as a sustainable concept into question. In order to shed light on the underlying cause of the ambiguity, we conducted 37 in-depth interviews with founders and senior managers of sharing ventures. Our comparative analysis identifies two distinct sets of contextual factors, which influence their sustainable activities. The first set of contextual factors enhances sustainable activities by enforcing the adaptation of behavioral rules and by enabling the development of organizational capabilities. The second set of contextual factors restricts sustainable activities by impeding market penetration and by suppressing growth. We contribute to theorizing about sustainable entrepreneurial ecosystems by delineating the conjoint effect of contextual factors on sustainable activities. Furthermore, our results add insights into the controversial academic debate about the sustainability dimension in the sharing economy.

  • Liu, Y., and Hu, H. 2021. Online Review Helpfulness: The Moderating Effects of Review Comprehensiveness. International Journal of Contemporary Hospitality Management Volume 33 Issue 2 pp. 534-556

Consumers’ evaluation of online review helpfulness has been widely examined. The extant literature suggests that the attributes of review content (e.g. review length and extremity) influence review helpfulness. However, review length cannot fully reflect the richness of the review content. Anchoring on information diagnosticity and extremity bias, this study aims to explore the effect of review comprehensiveness on its helpfulness. Field observations were obtained from 11,812 online restaurant reviews on a popular restaurant review platform. A controlled experiment was conducted to further delineate the effect of review comprehensiveness. Review comprehensiveness moderates the effects of review length and an extremely negative review on helpfulness. It also confirms that for reviews of the same length, one covering more aspects is perceived by consumers as more helpful. Different aspects of information in a review can efficiently assist decision making. The results suggest that review platforms can better design their interface by providing separate areas for different product aspects. The platform can then receive more comprehensive and helpful reviews and increase the diagnosticity of these. The study enriches the literature by introducing review comprehensiveness and examining the joint effects of review length and comprehensiveness on helpfulness. It also contributes to the literature by indicating how to reduce the effect of review extremity.

  • La Rocca, A., & Snehota, I. (2021). Mobilizing suppliers when starting up a new business venture. Industrial Marketing Management, Volume 93, February 2021, Pages 401-412

Prior research has shown that new ventures can complement their capabilities and extend their limited internal resources by drawing on suppliers. Yet, our knowledge of the supplier mobilization process in new ventures is limited. In this paper, we take a relational perspective on the mobilizing process, which entails investigating the scope for mobilizing suppliers in new ventures and new ventures’ attractiveness to suppliers. Drawing on three new venture cases, we posit that for new ventures the scope for mobilizing suppliers: 1) ranges from the use of suppliers for the procurement of well-defined existing inputs to the co-development of various resources and capabilities with suppliers; 2) varies across ventures, reflecting the new venture’s distance to market; and 3) depends on the supplier’s assessment of the new venture’s attractiveness as a customer. We also argue that the attractiveness of new ventures as customers to the suppliers is based on elements that differ from those found in studies of ongoing businesses, and include: 1) stimuli to innovate and develop new competencies, 2) reputational benefits and prestige, and 3) personal satisfaction.

In this paper, a sustainable two-phase sequential approach is proposed for the design of bioenergy SCs under uncertainties. The first phase, integrating geographical information, social aspects, and multi-criteria decision-making techniques, helps find appropriate locations for the bio-refineries. High rates of unemployment, and high vulnerability to the variation in the markets in an economic crisis are considered as social concerns. Integrating these factors filters the areas for the second phase. The first phase reduces complexity in the computation of the problem and helps set up sustainable development in the supply chain. In the second phase, to cope with the uncertainties in the bioenergy supply network, a robust model is introduced. It reduces the sensitivity to inaccurate input data, and the obtained solutions stay optimal when the parameters change slightly. In order to validate this two-phase sequential approach, a case study is investigated. The results of tests show that integrating the concepts of uncertainties and sustainability with geographical information of the area in a two-phase sequential approach outperforms the traditional models and leads to the creation of 262 jobs. The jobs have a high impact on the surrounding area.

The current study aims to understand the detrimental effects of COVID-19 pandemic on employee job insecurity and its downstream outcomes, as well as how organizations could help alleviate such harmful effects. Drawing on event system theory and literature on job insecurity, we conceptualize COVID-19 as an event relevant to employees’ work, and propose that event strength (i.e., novelty, disruption, and criticality) of COVID-19 influences employee job insecurity, which in turn affects employee work and non-work outcomes. We also identified important organization adaptive practices responding to COVID-19 based on a preliminary interview study, and examined its role in mitigating the undesired effects of COVID-19 event strength. Results from a two-wave lagged survey study indicated that employees’ perceived COVID-19 event novelty and disruption (but not criticality) were positively related to their job insecurity, which in turn was positively related to their emotional exhaustion, organizational deviance, and saving behavior. Moreover, organization adaptive practices mitigated the effects of COVID-19 event novelty and criticality (but not disruption) on job insecurity. Theoretical and practical implications are discussed.

Expungement mechanisms allow first-time offenders to seal their criminal record. Theory predicts that the stigma of a criminal record can hinder the reintegration of criminals for whom legal activities are less lucrative. In theory, expungements priced at the reservation level can facilitate the reintegration of criminals without making first-time crime more attractive. This paper considers a behavioral perspective and offers experimental evidence about the impact of expungements priced at different levels. To do this, we set up a laboratory experiment where subjects repeatedly face opportunities to commit crime (takemoney from another subject). In addition to stochastic formal sanctions – imposed by the experimenter– we introduce endogenously determined social sanctions. In our main treatments of interest, subjects who choose the wrongful action have the opportunity to expunge their record prior to the second stage, thus avoiding social sanctions as long as they do not recidivate. Overall, our experiment shows that, from a general deterrence perspective, it is better to implement expungements at very high prices. We offer an explanation for this result based on the idea that the price of expungements may signal the moral reprehensibility of the offense.

One of the most applied value scales in research is personal shopping value (PSV) by Babin, Darden, and Griffin (1994). PSV assesses consumers’ shopping experiences along hedonic and utilitarian value. The purpose of this research is the corroboration of the original article and the PSV scale to investigate the impact of the past 25 years on the scale’s dimensionality and item composition. The corroboration mirrors the original store environment, while an extension additionally considers two contemporary shopping environments: online websites and mobile apps. Results across six studies confirm shopping value’s two-dimensional structure of work and fun. However, individual items capturing hedonic and utilitarian value deviate from original PSV scale items in number and nature for current stores, online, and mobile apps environments. Researchers and practitioners should exhibit caution to blindly administer or adapt measures without considering temporal or contextual aspects of the scale that limit its applicability.

  • Alexakis, C., Vasilis Pappas, Manolis Skarmeas (2021) Market abuse under different close price determination mechanisms: A European case. International Review of Financial Analysis 74 (March 2021) 101707

We examine the presence and the severity of closing price manipulation across two regulatory shifts in the close price determination mechanism in the Athens stock exchange. First, we assess the transition from a value-weighted average price (VWAP) method to a plain-vanilla closing call auction method (CCAM). Second, we examine the effectiveness of additional features of CCAMs in deterring closing price manipulation. We use tick level data with full investor details for a group of highly traded stocks. Our results suggest that the CCAM managed to reduce – but not eliminate – closing price manipulation. CCAMs with additional anti-manipulation features are not effective in eliminating closing price manipulation either. Manipulation is dynamic and investors quickly adapt to new circumstances and opportunities; post-CCAM implementation sell-based closing price manipulation has increased, while part of the manipulation activity has shifted to the reference price formation.

This paper offers the first-ever look at Bitcoin options by investigating the wedge between optimum Bitcoin option prices based on classical option valuation models (Black-Scholes-Merton and the Heston-Nandi GARCH (1,1)) and actual premiums at which these options are trading. For this purpose, we use near-the-money call and put options traded on Deribit platform as on 27.01.2020, with the maturities ranging from January 31 to 25 September 2020. In addition, we analyse the risk inherent in Bitcoin options by calculating their Greeks and comparing them to those of traditional commodity options. Pricing results suggest slight overpricing and underpricing for Bitcoin call options with the strike $8,000 maturing on 30.01.2020 and 28.02.2020, respectively. We also find that the Bitcoin options provide much stable deltas over time compared to the other commodity options. This result implies higher insulation from undue price rises with the passage of time for investors in Bitcoin options. Our results are useful to regulators, investors and market managers in better understanding the nuances of the Bitcoin options market in addition to making more informed investment choices.

A large-scale field experiment in Rotterdam, Netherlands, tested whether nudging could increase public transport use. During one work week, 4000 commuters on six bus lines, received a free travel card holder. On the three bus lines in the experimental condition, the card holders displayed a social label that branded bus passengers as sustainable travelers because of their bus use. On the three bus lines in the control condition, there was no such message on the card holders. Analysis of the number of rides per hour showed that the intervention led to a change from pre-intervention (619 days) to postintervention period (176 days) that was estimated to be 1.18 rides per day greater on experimental lines than on control lines. This experiment shows that public transport operators can increase public transport use by incorporating messages that positively label passengers as sustainable travelers in their communication strategies.

The short-term room rental online platforms have boomed in the era of digital business acceleration, as they offer excellent opportunities for interactive behavior between host and guests. However, pursuing customer repeated bookings is a challenge on these platforms. How to increase customer repeated bookings in the short-term room rental market? We examine theoretically and empirically this crucial research question. Drawing on the theoretical foundations of the social interaction theory, we identify and study three host-guest interactions that can affect customer repeated bookings: overall interaction, individual interaction, and offline interaction. We conduct a combination of empirical methods, including text mining and econometrics, using longitudinal data of 36,072 order records and review contents from 5002 listings and 2181 hosts in six cities, which is a prevalent short-term room rental services provider in China. We find that overall host-guest interaction (online reply rate, acceptance rate, confirmation time) and individual host-guest interaction (the existence of individual interaction, absolute text length, and text similarity) increase customer repeated bookings. We also discover that offline host-guest interaction is a substitute for the effect of individual interaction (existence, text length, and similarity) on customer repeated bookings.

This study considers two retailers that offer substitutable products and compete in a greenness- and price-sensitive market. The retailers rely on supply chains that have different costs, replenishment times and carbon intensities. The demand is stochastic, and the inventory replenishment time is also stochastic. Each retailer decides the greenness of its product (carbon intensity), the price and the order size to maximize its expected profit under a service level constraint. The mean demand for each retailer decreases in its price and carbon intensity and increases in other retailer’s price and carbon intensity. The customers’ switchovers are, thus, governed by disparities in carbon intensity and price. The retailers may have different market powers since the total demand is not necessarily equally shared between them when they offer the same price and greenness level. We derive analytically the best response of each retailer to other retailer’s decisions at the Nash equilibrium. We determine the market conditions that lead the competing retailer to offering a greener or a dirtier product than the product it would have offered in a monopolistic situation. We explain how the retailer’s market power impacts on its greenness strategy under different market conditions. We also investigate insights into the impact of disparities in transportation carbon emissions, the order size decisions, and the retailers’ optimal profit under the different competition scenarios.

While antispeciesism is an ethical notion, veganism is behavioral. In this paper, we examine the links between the two. Building on Blackorby and Donaldson (EconJ 102:1345–1369, 1992), we consider a two-species model in which humans consume animals. The level of antispeciesism is conceived as the weight on animals’ welfare in the utilitarian social welfare function. We show that more antispeciesism increases meat consumption if and only if animals’ utility is positive. That is, the critical condition is whether farm animals’ lives are worth living. We then empirically explore this condition using a survey. We find that farm-animal experts and frequent meat eaters are more likely to believe that the lives of farm animals are worth living. We finally discuss some issues in the study of animal welfare in economics and social choice.

We investigate how managers in French companies report their engagements and motivations regarding corporate social responsibility (CSR) in 2007 and 2017. We conducted and analysed 14 in-depth structured interviews with managers in 2007 and again in 2017. Thematic analysis shows that in 2007, managers focused on instrumental motivations for CSR, citing economically driven artefacts and pro-environmental efforts. In 2017, most managers reported increased and reinforced environmental and social engagements with a parallel shift in the expression of their motivations, seeing CSR as a responsibility to society and future generations, or as a normal, natural activity.

Online peer-to-peer (P2P) lending volume has rapidly increased in China because of high financing and investment demands. However, high borrowing default and fraud rates have negatively affected Chinese online P2P lending because of its unique financial and unde¬veloped credit systems. They have prompted the Chinese government to issue regulations on Internet finance behavior to support online P2P lending. This research investigates online P2P lenders’ investment perceptions to understand investment intention related to online P2P lending. The research model is based on planned behavior theory. A ques¬tionnaire on attitudes collected data from voluntary participants; the data were analyzed with confirmatory factor analysis and structural equation modeling. The findings show that lenders’ attitudes, behavioral controls, and subjective norms—and those three constructs’ antecedents, except relative advantages—have a positive and significant influence on lend¬ers’ online P2P lending intentions.

This paper examines the determinants of the emerging market banks’ derivative usage and the impact of derivative usage on bank value, total risk and bank stability. Our empirical evidence first suggests that derivative usage is driven primarily by net interest margin, bank concentration and institutional strength. In addition, although derivative usage appears to reduce emerging market bank value, it does not affect total risk. Moreover, emerging market banks can reduce bank instability using derivatives. Our findings have important implications for investors and policy makers focusing on emerging derivatives markets.

Snacking typically occurs as an automatic, consciously uncontrolled process which can lead to unintended health consequences. Grounded cognition informs about the multifaceted drivers of such automatic consumption processes. By integrating situation-, stimulus-, and person-specific factors, this study provides a holistic account of snacking. A combined psychophysiological and behavioral experiment is conducted wherein participants can casually snack chocolate while participating in a survey setting. Implicit cognitions are assessed with the Implicit Association Test. The percentage of consumed chocolate serves as dependent variable in a Tobit regression with predictors at situation, stimulus and person level. Findings – Chocolate snacking is positively influenced by personal craving tendencies, implicit food associations and situational contingency. We condense the results into an overarching framework in line with grounded cognition literature. The multidimensional framework can guide consumer protection efforts to reduce excessive snacking habits based on situation, stimulus and person. This study integrates theory from social cognition, consumer research, and behavioral food research and, thereby, extends the existing body of knowledge on grounded cognitions underlying snacking consumption.

Research on social networks and innovation emphasizes that individuals spanning structural holes and crossing institutional boundaries have more opportunities for knowledge recombination and innovation involvement. However, transforming the potential knowledge and resources available through personal networks to attain innovation can be difficult for the focal individual. Using an ego-network approach, this study examines whether and to what extent an individual strategic orientation to cooperation (i.e. tertius iungens) contributes to strengthening the relation between two personal network properties (structural and institutional separation) and involvement in innovation. Our analysis is conducted in the context of biomedicine, where research networks are particularly relevant for science and innovation achievements. Our findings advance social network theory by decoupling social network mechanisms from individual strategic networking behavior as factors influencing knowledge generation processes. Results also provide original evidence on an overlooked phenomenon: the moderating role of a tertius iungens orientation in the relationship between multiple social network properties and innovation. Finally, our research sheds new light on the distinct sources of knowledge recombination in networks and the role of individual networking strategies to facilitate mobilization of resources for innovation.

We apply these findings, integrated with prior research on effective economics writing style, to recommend how energy economics articles should be written to increase their impact. These recommendations center particularly around the importance of initial article information provided to the reader and article structure.

Research has largely shown a positive linear relationship between proactive personality and job performance at the individual level. However, it remains unknown whether the same relationship holds at the team level. In this research, we propose and test a curvilinear relationship between team mean level of proactive personality and team performance. We also examine team potency and team cohesion as the explanatory mechanisms and the dispersion of proactive personality as a boundary condition for the relationship. We conducted two studies to test these ideas. In Study 1, we collected data from 93 teams in four companies from different industries. In Study 2, we collected data from 101 nursing teams in three hospitals. We found a curvilinear relationship between team mean level of proactive personality and team performance in Study 1 and replicated it in Study 2. We further demonstrated in Study 2 the moderating role of dispersion of proactive personality and the mediating role of team potency and team cohesion, respectively, in this curvilinear relationship. The positive trend of the curvilinear relationship is strengthened (weakened) when the dispersion of proactive personality is high (low). The negative trend is mitigated under high dispersion of proactive personality but is not significant under low dispersion of proactive personality. Practically, managers must be aware that team mean level of proactive personality benefits team performance only up to a certain point

While extant research on entrepreneurial ecosystems has focused on macro-level factors influencing the ecosystem’s development, the role and impact of entrepreneurial practices have been neglected. The objective of this study is to address this research gap and to shed light on the micro-level practices of entrepreneurs who support sustainability transitions in entrepreneurial ecosystems. Our inductive study looks at these micro-level practices from the perspective of sustainable ventures situated in the sharing economy. We conducted 31 in-depth interviews with the founders and senior managers of sustainable ventures to investigate how they advocate the sustainability cause in their ecosystem. Our findings show that sustainable entrepreneurs rely on three distinct sets of micro-level practices: building a supportive environment, disrupting normative standards, and reframing the sustainability paradigm. Also, sustainable entrepreneurs engage in political work to strengthen their position and credibility in the sharing economy, which is being increasingly dominated by profit-oriented players and business practices. By substantiating the central role and micro-level practices that sustainable entrepreneurs enact to advocate sustainability, our study contributes to theorizing the sharing economy. Furthermore, our resultant framework provides a detailed overview of the distinct micro-level practices that help ventures to support the sustainability transition in entrepreneurial ecosystems.

The carousel is an important automated storage and retrieval system. Customer orders to be collected from carousels are grouped into batches and the orders of a batch are collected simultaneously. We study two batching methods for picking from multiple carousels: (i) fixed batching, where all orders belonging to a batch are collected before the next batch is started, and (ii) rolling batching, where each time an order belonging to the current batch is completed, it is immediately replaced by a new order. For these methods, the main decision is respectively to allocate orders to different batches and to define a sequence for adding orders into batches. With the objective of minimising the total completion time, we develop models for fixed and rolling batching. Thanks to our collaboration with the company KLS Logistic Systems, we use real data to test and prove the efficiency of our models. With comparison to current batching strategies of real companies and to benchmark heuristics, our models yield a considerable time saving. Our findings also indicate that an increase in order size favours the rolling batching over the fixed batching. The models developed in this paper have been implemented and are currently being used in practice

This study examines how carbon performance affects carbon disclosure and how carbon disclosure affects financial performance. With a sample of global firms, the study analyses how relationships between carbon disclosure, carbon performance and financial performance vary in institutional contexts. Our results show that carbon disclosure positively affects carbon performance, consistent with the signalling theory. We find that carbon disclosure negatively (positively) affects financial performance in the short-term (long-term). Our findings have significant implications for investors as some firms use carbon disclosure as part of impression management. Our results help regulators to monitor carbon disclosure and assist investors with investment decisions.

Journal of Consumer Behavior, Volume 20, Issue 3, pp.550–563

Consumers’ internalisation of social norms is at work when they make routine, healthier food choices in everyday contexts. We investigate the dynamics of this phenomenon in Singapore, where over 98% of consumer food products are imported. To study this, we propose, through a consumer perspective (n = 316) via Partial Least Squares Structural Equation Modelling (PLS-SEM), a model that establishes a positive relationship between perceived usefulness, subjective norms, and intrinsic motivations and the perceived value of healthier food. Subjective norms are themselves found to be a function of perceived barriers, facilitating conditions and personal innovativeness. Our framework contributes to establish a shift in the drivers of healthier food choices toward a more socio-culturally grounded decision-making approach that is particularly relevant to understand food consumption. We show that daily food routines (opposing the exceptional healthy food item) are encapsulated in perceived value of healthier eating. The data indicates further that to support healthier food product consumption, both policy makers and food providers must facilitate imported foods that meet quickly changing lifestyle requirements.

Can social media-driven customer engagement help movie producers to increase movie sales? Movie producers use social media to boost customer engagement; however, our understanding of whether there is a relationship between pre-consumption customer engagement and movie sales is limited. This research explores what drives the success of movies on the opening-weekend. We examine the relationship between pre-consumption customer engagement driven by social media (i.e., personal and interactive engagement) and movie performance (i.e., opening-weekend box office revenues). Driven by the debate about the potential capacity of social media-driven customer engagement to improve movie performance and the limited understanding of the association of pre-consumption customer engagement and movie performance, this research suggests that social media-enabled customer engagement (i.e., personal and interactive engagement) has the potential to improve movie performance, and these two types of engagement can interact to make this effect stronger. We analyze these relationships drawing from the uses and gratifications theory and the social media affordances perspective that motivate customers to interact in social media. The theoretical model evaluation was tested on a unique and original dataset composed of 966 movies released in the U.K. and Spain. The empirical analysis suggests that personal and interactive engagement are positively related to movie performance, and the positive effects of personal and interactive engagement on movie performance are mutually reinforcing. This research contributes to Information Systems (IS) research by theorizing and empirically showing how customer engagement driven by social media creates business value by improving movie performance.

  • Hammami, R., Frein, Y., Albana, A.S. (2021) Customer rejection to guide lead time quotation and pricing decisions. Journal of the Operational Research Society, 72(6), 1358-1372

The lead time (LT) quotation and pricing models in make-to-order environments usually assume that all arriving orders are accepted. Hence, despite the loss of demand, the firm must quote a relatively long LT to tackle the situations where there are too many waiting orders. This paper investigates the policy of accepting orders based on the state of the system and, consequently, rejecting customers when the number of waiting orders is larger than a given threshold value. Indeed, if there are less than K jobs in the system (K fixed), then the new order is accepted and a pair of LT and price are quoted to the customer. Otherwise, the order is rejected. Thus, we model the firm’s operations as a M/M/1/K queue instead of the commonly-used M/M/1 queue. We determine the optimal solution for K = 1 and solve the problem numerically for K ≥ 2. We show that our policy can be more profitable than the all-orders acceptance policy. We provide insights into when should a K be imposed and how such a K should be chosen. We find that the higher the sensitivity of demand to price or to LT is, the lower the optimal value of K.

This paper provides a systematic review and analysis of the game-theroy-based research in Green Supply Chains Management (GSCM). Based on a rigorous content analysis of 108 papers carefully selected from the literature, we present a detailed picture of the current state of this research and point to the promising future directions. Our analysis shows a rapid increase in the number of publications during the last three years, with an imbalance in the contribution of the publishing outlets, as nearly two third of the reviewed papers are published by only four journals. Results also show the dominance of deterministic static models and simple two-level SC structures. Developing stochastic models, considering the risk and the evolutionary nature that inherently characterise the business environment and investigating more complex multi-level SC structures are among the promising future research opportunities.

In this study we quantify and analyze the dynamic dependence between US, eurozone, UK and Japan Bitcoin market returns and realized and unexpected inflation, conditional on different market states and various nuances of inflation. Using a Quantile-on-Quantile regression, we investigate the hedging properties of Bitcoin against inflation, thereby offering a fresh look at the return-inflation puzzle from the point of view of alternative investments. We find that while bullish UK, Euro and Japanese Bitcoin markets facilitate hedging against inflation by offering higher returns, the USD Bitcoin market performs worse with inflation. In general, our results indicate an asymmetric relationship between inflation, both realized and unexpected, and alternative investments such as the Bitcoin market.

Consumers’ responses to design features involve both conscious and non-conscious information processing. The current research therefore argues that a combination of explicit and implicit measures should be used to assess consumer understanding of service brand meaning conveyed by a service brand’s physical elements. However, most methods traditionally used to evaluate design meaning are explicit methods, based on conscious cognitive processes. The current research addresses this gap by documenting how understanding of service brand meaning conveyed by a service brand’s physical elements can be tapped by an implicit measure. More specifically, it aims to investigate the extent to which a greater ability to decode meaning conveyed by design features results in differences in implicit understanding of service brand meaning. This research uses a Semantic Priming Task to assess associative strength between brand meaning and a service brand’s physical elements. Results (N ¼ 157) show that command of the design language, captured by design acumen and involvement in the product category, results in greater ability to implicitly understand brand meaning conveyed by a service brand’s physical elements, and moderates the implicit-explicit relationship. Results suggest that combining implicit and explicit measures may help practitioners in charge of creating brand’s physical elements, especially when associations between design types and brand impressions are not constant across product categories.

Research on the relationship between novelty and travel intention is lacking. This study attempts to fill this gap by developing a theoretical model to explain how novelty influences travel intention through two mediating paths: brand equity and tourist motivation. In this study, data were collected from 466 foreign visitors to Taiwanese night markets. To test the model, the authors applied structural equation modeling (SEM) to identify the critical attributes that predicted foreign tourists’ travel intentions. The SEM analysis indicated that novelty in tourism management was related to brand equity and intrinsic motivation, which increased foreign tourists’ travel intentions and offered advantages for highly competitive, high-density night markets in Taiwan. In addition, brand equity was an important mediator that connected novelty and tourists’ travel intentions. Finally, novelty indirectly affected travel intention and intrinsic motivation through brand equity. There may exist potential moderators in the relationships among the brand equity and travel intention categories. Future research studies could explore whether any moderators influence the relationship mechanisms examined in this study. This research expands on previous research studies that have focused on the value of travel intention. Furthermore, the study uses brand equity theory (BET) and the theory of planned behavior (TPB) to examine the mediating effect of intrinsic motivation on the relationship between novelty and travel intention.

This study examines the impact of tenure in independent directors and audit committees on accretive share buybacks for real earnings management. Taking a sample of 601 non-financial firms listed on Bursa Malaysia from 2010 to 2015, we use a tobit model to test our hypotheses, where real earnings management is proxied by accretive share buyback. We find a significant effect of the tenure of outside directors on accretive share buyback. Firms with long-serving independent board directors are more likely to undertake real earnings management through accretive share buyback. Evidence is also found that firms with audit committees including long-serving members are more likely to engage in share buyback to maximise reported earnings per share (EPS) for earnings management. Finally, a high percentage of independent directors on audit committees restrain managers from utilising accretive share buyback to manage reported EPS.

In the real world, various products are displayed simultaneously on the shelf; therefore, their demands/prices affect each other. This paper aims at studying a joint economic lot-sizing model with two complementary products in a supply chain consisting of a vendor and a buyer. The vendor sends items to the buyer’s warehouse in equal-size batches applying vendor-managed inventory with consignment stock policy. The buyer stocks items at the warehouse and on the shelf. Two mixed-integer nonlinear models that consider bundling and separate sales have been proposed and solved through different solution algorithms such that the profit is maximized. The concavity of both models’ objective functions is investigated and the effect of considering complementation between products and bundling strategy is studied. Numerical experiments indicate that the bundle’s marginal profit is greater than a single product’s marginal profit. Moreover, the supply chain members can also take advantage of economies of scale in bundling sales.

This study investigates the influence of buyer–seller personality similarities on compulsive buying behaviour in a dyadic setting. To provide insights into the gaps in previous research, we collected both buyer and corresponding seller data, and considered sellers’ personalities. Specifically, using difference score analyses and variance-based structural equation modelling, we analysed 1038 buyer–seller dyads in service encounters. Compared with the effects of individual buyers’ personalities on compulsive buying, the combined personality results showed that buyer–seller agreeableness similarities increase the compulsive buying behaviour of agreeable buyers. On the other hand, buyer–seller similarities in openness and neuroticism reduce compulsive buying. A further analysis showed that buyer–seller interactions mediate the effect of their extraversion and openness similarities on compulsive buying, while buyers’ shopping enjoyment mediates the effect of their extraversion and neuroticism similarities on compulsive buying. Overall, compulsive buyers have interpersonally different buying behaviours when their personalities match (differ) with their corresponding sellers’. Thus, marketers can match agreeable buyers with similar sellers to promote sales, while dissimilar sellers should be complemented with openminded and neurotic buyers, in particular, to reduce losses.

Environmental non-governmental organizations (ENGOs), one of the major forces in environmental protection, have developed rapidly in the past few years, especially in developing countries such as China. This paper aims to reveal how the ENGOs select their focuses, specifically if they only concentrate on one focus or on contexts in which they obtain various focuses and the motivations behind their choosing strategies. The current research interviewed 103 leaders of ENGOs covering every province in mainland China and adopts existing theories of NGOs alongside diversification strategy from a management perspective. The results showed that most Chinese ENGOs now tend to be diversified but face different challenges. This research highlights the importance of ENGOs’ resources and capacities in facing current challenges and suggests directions to improve their diversification strategy. This research adds value to the research of environmental NGOs and gives suggestions to environmental NGO practitioners, in particular to those in emerging markets.

This paper examines the effect the impostor phenomenon (IP) on short-term emotions (shame) and performance (creativity and organizational citizenship behavior- OCB) at work, and on career outcomes. Previous research shows direct detrimental effects of IP on some short-term performance measures, but effects on creativity and OCB remain under-researched, and no work has investigated any career effects. Through an experimental approach (Studies 1 and 3) and an online vignette (Study 2) using working populations, we find that IP is expressed as shame in response to simulated and recalled real work events. Shame mediates the negative effect of IP on creativity, and its positive effect on OCB, and mechanistic organizational structure exacerbates the negative shame-creativity relationship. Furthermore, Study 4 uses a survey design to reveal that IP relates negatively to external employability and career success. Drawing on conservation of resources theory, we suggest that IP and shame deplete resources such that impostors suffer reduced ability to perform well at work in the short-term, with negative consequences for career success.

  • Espinosa, R. and Treich, N. (2021). Moderate Versus Radical NGOs†. American Journal of Agricultural Economics.Volume103, Issue 4, August 2021, pp 1478-1501

NGOs often vary in terms of how radical they are. In this paper, we explore the effectiveness of NGO discourses in bringing about social change. We focus on animal advocacy: welfarist NGOs primarily seek to improve the conditions in which animals are raised and reduce meat consumption, whereas abolitionist NGOs categorically reject animal use and call for a vegan society. We design an experiment to study the respective impact of welfarist and abolitionist discourses on participants’ beliefs regarding pro-meat justifications and their actions, namely their propensity to engage in the short run in animal welfare (charity donation, petition against intensive farming) and plant-based diets (subscription to a newsletter promoting plant-based diets, petition supporting vegetarian meals). We first show that both welfarist and abolitionist discourses significantly undermine participants’ pro-meat justifications. Second, the welfarist discourse does not significantly affect participants’ actions, although we detect a potential backlash effect of the abolitionist discourse. We show that the NGOs’ positive standard effect on actions through the change in beliefs is outweighed by a negative behavioral response to the discourses (reactance effect). Last, greater public-good contributions are associated with greater engagement in animal welfare in the presence of an NGO discourse.

The Covid-19 pandemic continues to disturb the global economy and capital markets. Governments across the globe relentlessly enact health policy measures to contain coronavirus and undertake economic relief programs to reduce the impacts on their economies. This paper examines the effects of Covid-19 government health measures on the volatility of capital markets in East Asian economies. The study applies Monte Carlo type simulations to determine stock price volatility over the period when health policy measures were implemented. The findings indicate that different health policy measures have affected investors’ behavior and caused volatility of stock markets. However, there are country-different impacts on the volatility of these capital markets. The findings provide important insights that are useful when reviewing Covid-19 health policy measures to mitigate the impacts on stock markets.

Buoyed by the desire to reduce carbon dioxide emissions and develop sustainable urban transportation, the dockless bike-sharing industry boomed in China during 2017–2018. To the surprise of the stakeholders, this industry dramatically ebbed in 2019. The dockless bike-sharing system deviated from a problem-solver to a troublemaker in a very short period. The oversupplied and excessively discarded shared bikes caused a big waste of resources and serious pollution to the environment. In this paper, the decision-making of the key players of the industry, i.e. business operators, investors, customers and government, is analyzed through the lens of the cognitive bias. This paper aims to illuminate the process of how this innovative transport solution turned to a disastrous ending, which caused damage to urban environment and financial loss to investors. In this study, a qualitative analysis based on the rich secondary data sources is conducted. A rich amount of qualitative data including news reports, government policies, consulting reports and companies’ annual reports etc. were collected. The study shows, in the product introduction period, the government, business operators, investors and consumers fell into the cognitive bias. They over focused on the positive side such as high-tech, eco-friendly, convenient image of the dockless bike-sharing solution. Thereby, the key stakeholders made irrational decisions in product adoption and management. This study moves toward increasing key stakeholders’ awareness of the imperative to reduce these biases when promoting eco-innovations. This study also recommends a prudent attitude with a rational and comprehensive thinking style in dealing with eco-innovation and the emerging sharing economy. To solve the cognitive biases, this study recommends that people use rational decision-making style to examine and adopt the dockless bike-sharing solutions. Practical recommendations to tackle the existing recycling crisis of the dockless bike-sharing industry are also discussed.

How to enter and expand in a newly emerged foreign market is less understood. Should multinational enterprises move fast or slowly? In this study, the authors take China as the context to investigate what factors will lead to a fast expansion strategy in a foreign market. The purpose of this paper is to understand whether fast expansion benefits firms’ performance in a rapidly emerging market. Based on insights from field interviews, the authors developed a theoretical framework. Then, the authors collected data from surveys of managers of multinational enterprises from Western countries to test their hypothesis. This research context is based on the experience of multinational enterprises in China which opened up to foreign direct investment in 1979. This study shows that internally, strategic long-term investment goals, top management team commitment and externally switching costs and the growth in the demand market which will push firms to expand fast in the newly emerged China market. Faster pace of expansion benefits the performance of multinational enterprises in a newly emerged market. Based on the onsite interviews followed by the survey of top managers of multinational enterprises located in China, this study provides a fine-grained analysis of the importance of pace and its key antecedents. Thus, the results provide new insights to decision-makers of multinational enterprises when considering expanding in an emerging market at its early stages of growth.

Promoting energy conservation in university dormitories is challenging because student residents are typically charged a flat utility fee. One possibility to curb excessive energy use in the absence of monetary incentives is to highlight the environmental consequences of energy use. However, it is still largely unknown how these consequences should be communicated to effectively change people’s behavior. In the present study, we analyzed the effect of framing the environmental consequences of energy use in terms of losses versus gains on the air-conditioner use of student residents of a Japanese university dormitory. A total of 330 students were provided with stickers to attach to the air-conditioner remote control in their dormitory room during the winter term. The stickers conveyed that increasing the temperature will hurt the environment (loss frame), that reducing the temperature will protect the environment (gain frame), or that changing the temperature will affect the environment (neutral frame). Day-to-day variations in objective air-conditioner use data were analyzed as a function of experimental condition to examine the effect of message framing. The change in air-conditioner use from pre-intervention to intervention period did not differ between experimental groups and neither did the change from pre-intervention period to a period after the intervention

We investigated how hotel customers’ satisfaction is influence by the financial performance of the hotels. We extracted the satisfaction ratings from Trip Advisor for 3,4 and 5 star hotels in Greece. Financials wee extracted from hotels’ financial statements. Our findings show that the hotels in each star category have different financial profiles and attract different customer satisfaction ratings. 5-star hotels attract the highest customer satisfaction score and also have greater asset investment, more beds, and higher revenue/bed. In terms of expenses, the 5-star hotels have higher cost of goods sold, and lower administration and selling expenses as a proportion of revenue. Lastly, there is a lower prevalence of swimming pools in 5-star hotels, perhaps partially reflecting the business focus as opposed to tourism focus of these hotels.

Bitcoin futures were introduced in December 2017 and this was seen by some as a sign of the most popular cryptocurrency finally being accepted by the financial community. In this paper, we examine the impact of the introduction of Bitcoin futures on the Bitcoin spot market in terms of five characteristics – returns, volatility, skewness, kurtosis and liquidity, using a Bayesian diffusion-regression (state-space) structural time-series model. Our results indicate that the introduction of bitcoin futures potentially exerted a downward impact on the USD bitcoin spot market return and skewness and an upward one on volatility, kurtosis and liquidity, which became higher after futures were introduced. Therefore, our paper offers important insights for investors and regulators, while providing some guidance as to the potential impact of futures markets on other cryptocurrencies.

This study fills a gap in the consumer emotions literature regarding customer frustration in a customer service setting. Most research on customer emotions has examined anger, happiness or affect in general, largely ignoring the particularities of frustration. Consistent with appraisal theory, we use five experiments to explore the different appraisal dimensions that define frustration and its relation to customer loyalty and satisfaction. Contrary to common belief, we show that frustration is not simply the result of goal‐blocking, but rather of a more complex combination of appraisals which differentiate it from anger and lead to distinct effects on satisfaction and loyalty. We also examine how the effects of frustration on loyalty and satisfaction are mitigated by service recovery in a further experiment and an event reconstructive method. Our results test appraisal theory, inform theory on customer emotions and have important implications for our understanding of customer satisfaction and loyalty following frustrating customer service encounters

Sukuk investments require investors and issuers to adhere to subtle moral and ethical standards beyond following mere profit maximization objectives. Investor trust manifested through the level of societal trust could be vital in the global Sukuk investment surge. This study investigates the relationship between the societal trust level and Sukuk activity. It employs a global sample of Sukuk issuances spanning over 2001–2019 and finds that a country’s societal trust level significantly and positively influences the amount of Sukuk issued. Moreover, this positive effect supersedes the negative effects of higher information asymmetry associated with equity-based Sukuk or Sukuk issued by risky firms. Ultimately, trust is both a deterrent and critical for Islamic finance success.

We provide a comprehensive structuring of research on Islamic economics and finance into the core topics of the area, for the period 1979 to 2018. This is carried out through a probabilistic topic modeling approach that allows statistical learning of the connection between research articles as well as their shared topics. This approach, which blends machine learning and natural language processing, helps provide a comprehensive structure to the literature. Our topic modeling analysis is conducted on approximately 1500 articles and suggests the Islamic economics and finance literature can be well-described by 11 topics. These topics cover economic, finance, and morality issues. Our research can be applied to provide a clear structure for ongoing research agendas in Islamic economics and finance as well as a framework for understanding research development in this area. We also note the differences between Islamic and conventional approaches to economics and finance research in order to highlight the inherent new contributions of this maturing area of research.

Whilst research in innovation ecosystems has focused on the connectivity, interdependence, and coevolution of actors, technologies, and institutions, there has been a gap in the study of these relationships between actors, with little explanation given on how mutually interdependent parties adapt. In this paper, we draw further on the ecological metaphor to present a view of innovation ecosystems as complex adaptive systems, where patterns of change emerge from microlevel coevolutionary interactions between actors. Drawing on this view, we explore related implications for our understanding of ecosystem boundaries, coevolutionary rules of interaction, and how ecosystems are energized through innovation. Specifically, we contribute to the literature by developing a novel account of innovation ecosystems where actors are bound together through changing modes of coevolution. Drawing on this account, we explore key theoretical and practical implications for our understanding of ecosystem actors, rules of interaction, and the wider innovation ecosystem. We conclude that innovation both maintains and drives change within the innovation ecosystem, by altering the microlevel rules of interaction and coevolutionary relationships between actors.

Evidence from a consumer experiment in Belgium. Food Quality and Preference, Volume 93, 2021, 104276

The application of Nutri-Score on food products is ubiquitous throughout Europe and studies demonstrating its potential to stimulate healthier food choices are accumulating. At the same time, a strong need exists to evenly harmonize and activate the communication of environmental impacts on food products, in synergy with the Nutri-Score. This raises the question of whether the Nutri-Score could be expanded to an ‘Eco-Score’ that would similarly encourage environmentally friendly food choices. This paper reports a randomized control trial, in which a representative sample of 805 Belgian consumers was asked to hypothetically buy ingredients for a meal in a small-scale mock-up E-grocery environment. The experiment tested whether a combined Nutri-Score and Eco-Score affected the nutritional quality and environmental impact of consumers’ food choices. This effect was compared to general and specific dietary recommendations on the one hand, and to detailed impact tables on the other hand. Since visual distraction often plays a role in informative persuasion, the treatments were evaluated subject to different levels of distraction caused by product images. The average nutritional quality index (NQI) and environmental impact index (EII) of the selected baskets were calculated to evaluate the effects of the manipulations. We find that a joint Nutri-Score and Eco-Score label improves the NQI but not the EII. The general- and specific recommendation as well as the detailed information also improved the NQI. However, the specific recommendation was the only treatment that also improved the EII. The improvements in NQI due to the scores could be explained by a reduced consumption of pork. The improvements in EII induced by the specific recommendation could mainly be explained by a reduction in beef consumption. Only very mild indications were found that product images interfered with the effect of the scores. This study provides some initial evidence and support for the use of dual Nutri-Score – Eco-Score label to induce transitions towards healthier and more sustainable diets. We also find that recommendations outside the classic Front-Of-Package label framework could be a promising way to realize such a transition. However, it remains to be tested whether similar effects occur in real E-groceries and on a longer time scale.

Although both institutional export assistance and entrepreneurial orientation (EO) contribute separately and positively to export performance, the interplay between them has received little attention. This study examines the role of international EO in deriving performance benefits from governmental and nongovernmental export assistance. In this longitudinal study, two surveys were administered at two different times: In 2011, 705 Bangladeshi apparel exporters were surveyed, and in 2019, a subsequent survey of 198 firms in multiple industries was conducted. The aim of the surveys was to assess the relationships between governmental and nongovernmental assistance, EO and export performance. The results of the first survey show that, while nongovernmental assistance influences performance directly and via EO, governmental assistance has only direct effects. Furthermore, the negative influence of government assistance on EO reduces the total effects and renders them nonsignificant. The results of the second survey demonstrate that government EPPs have both direct and indirect positive and significant effects on market performance, indicating a partial mediation, whereas quasi-governmental assistance has positive and significant direct effects as well as negative but nonsignificant indirect effects. Nongovernmental EPPs have both direct and indirect significant effects on international performance, indicating a partial mediation. The study has important implications for researchers studying export assistance and its impact on firm performance. Instead of adopting a parochial view of government assistance, this study categorizes such assistance into three types – government, quasi-government and nongovernment. Furthermore, this study bridges the export assistance and international entrepreneurship literature by including EO. Entrepreneurs must emphasize the use of government assistance in order to enhance export performance. However, to promote both entrepreneurship and performance, they must emphasize nongovernment assistance. Exporters should also capitalize on the assistance extended by various quasi-governmental agencies to bolster export performance. Given the performance advantage of export assistance, this study highlights the contribution of the private sector in promoting export entrepreneurship while shedding light on the pernicious role of (quasi-)governmental assistance in export entrepreneurship.

Advertising is crucial in influencing customers’ perceptions and purchase intentions, and numerous studies have investigated whether advertising expenditure has any significant impact on financial performance. A thorough understanding remains elusive: while several studies document a positive impact, others report that advertising has either a negative or a statistically insignificant effect. Three flaws among existing studies are responsible for this problem: bundling advertising with other forms of marketing, the inadequacy of expenditure as a measure and a failure to consider contingencies. Deviating from earlier studies, we examine the effect of advertising productivity on firm performance rather than the impact of the absolute amount of advertising expenditure. Moreover, adopting a contingency approach, we evaluate how market conditions of market dynamism, market complexity and market munificence moderate the relationship between advertising productivity and organizational performance. Drawing a multi-industry sample from the USA, this study demonstrates that advertising productivity has a positive impact on capital market-based performance measures, conditional on market conditions. We reveal new insights into when, why and to what extent advertising contributes (or not) to organizations’ financial performance.

  • Mahabubur Rahman, M. Ángeles Rodríguez-Serrano & Anisur R. Faroque (2021) Corporate environmentalism and brand value: A natural resource-based perspective, Journal of Marketing Theory and Practice, 29:4, 463-479

Given ever-increasing engagement of firms in corporate environmentalism over the past few decades, a multitude of studies investigated the antecedents and consequences of corporate environmentalism. Extant studies exploring the consequences of corporate environmentalism predominantly measured its effects on firm performance. However, to the best of our knowledge, no study thus far has explored whether or not the key pro-environmental initiatives pertaining to corporate environmentalism carried out by industrial firms have any effect on market-based assets, namely, brand value. This study endeavored to address this gap in the literature. Drawing on natural resource-based view of the firm (NRBV), this study argued that industrial firms committed to corporate environmentalism reap rewards in the form of higher brand value. This study investigated three salient areas of corporate environmentalism, namely, environmental innovation, efficiency in using natural resources and emission reduction. The findings of this research demonstrate that industrial firms that outperform in environmental innovation, use fewer natural resources, and reduce emission have a higher brand value. Interestingly, while environmental innovation and efficiency in using natural resources contribute fairly equally to brand value, ability to reduce emissions contributes the least to brand value creation.

This paper undertakes an up-to-date assessment of evolution and convergence in market power over 2013 and 2018 in the Eurozone banking markets in view of the progress towards completing the banking union. The results show that average market power measured by the Lerner index displays an upward trend up until 2016 declining thereafter. Further findings by employing the panel convergence methodology of Philips and Sul (2007) fail to support the hypothesis of integration in the Eurozone banking markets through market power convergence. Furthermore, club clustering tests reveal presence of three sub-clusters of countries with different speeds of convergence.

This study examines the relationship between board gen­der diversity and the corporate financial performance (CFP) of companies listed on the Qatar Stock Exchange. We use the ordinary least square (OLS) regression as the baseline technique along with the system GMM generalized method of moments (GMM) approach to mitigate the possible issue of endogeneity. Our analysis reveals that board gender diversity negatively affects CFP. Our findings are robust to the use of alternate measures of board gender diversity and free from endogeneity concerns as demonstrated by the re­sults of the system GMM regression estimates. Further, we explain the possible reasons of this negative relation, par­ticularly in the context of Qatar. An important implication of our findings is that they identify the factors that inhibit the women in Qatar from making significant contributions to board proceedings as well as to CFP in its male-domina­ted society.

Little is known about the effects of green performance on corporate insolvency risk. This study examines the relationship between green performance and firm insolvency risk from both theoretical and empirical perspectives. Using a panel of 179 US firms included in the Newsweek Green Rankings and a system generalised method of moments estimation which generates endogeneity-robust regression coefficients, we found that firms with higher green performance are at lower risk of insolvency. We further postulate and provide theory-based empirical evidence that the nexus between green performance and insolvency risk is contingent upon other internal and external boundary conditions. Specifically, this research documents that the nexus between green performance and firm insolvency risk is moderated by market power as well as industry competitive intensity. The results of this study are robust across several sensitivity analyses

This paper goes beyond the extant comparisons of Islamic and conventional investments by econometrically assessing their convergence dynamics, in a dataset spanning over 1996–2020, covering ten business sectors and five episodes of crisis. We use a dynamic multivariate framework to estimate time-varying correlations, which we submit to beta and sigma-convergence analysis. Subsequently we examine how convergence dynamics affect portfolio risk management and crisis propagation. Our results show strong convergence of Islamic and conventional investments. During crises conventional convergence rates double, but Islamic ones are less affected. Sectoral diversification works best for conventional investments; Islamic ones behave as a single entity. On average we document a 7% risk diversification benefit from Islamic investments, at a 64 basis points cost. Yet, at the epicentre of the Covid-19 financial crisis this rises to 466 basis points and highlights the resilience of these investments in an exogenous event. Islamic investments reduce volatility spillovers in the financial system, but they are progressively less insulated across time. Our findings withstand a battery of robustness checks and are primarily useful to policy makers and investors

As virtual agents become prevalent in many domains, virtual influencers have gone live on social media platforms, integrating human networks and interacting with users. Building on research on human-computer interactions, the Uncanny Valley hypothesis, and Computers Are Social Actors paradigm, this paper aims to investigate (1) virtual agents’ similarity to humans in terms of behaviour in human networks and (2) reactions to human versus virtual agents in human networks where this interaction is publicly visible. We analyse the posting behaviour of and reactions to one human, one human-like virtual, and one anime-like virtual influencer active on a popular social media platform via text and emoji postings over an 11-month period. We find that, despite the general positive atmosphere of the platform, the human-like virtual influencer receives significantly lower positive reactions, providing evidence for the Uncanny Valley. Additional measures of negative reactions show a similar pattern. We discuss these results within the context of authenticity and social identity on social media, providing recommendations for the implementation of virtual influencers in human social networks.

This study explores how individuals obtain knowledge, perceive information sources, behave, and form opinions while facing a pandemic at an early stage. We develop a conceptual model linking the predictors of individuals’ knowledge with people’s behavior and opinions. The model is empirically tested through a large-scale global survey of 15,552 respondents from 126 nationalities. Our results indicate that relying on one source of information does not lead to favourable behavior towards curbing the pandemic. Furthermore, we need to educate people and control misinformation spread on policy and social network platforms to curb emergencies collectively

Since the start of the oil counter-shock in June 2014, Algeria has experienced unprecedented twin deficits. The excessive monetisation of the public deficit coupled with other deep anomalies in the economy of this country acutely calls for reconsideration of its monetary policy. To this end a prior study of the long-run stability of money demand is needed. We estimate the demand for money for monetary aggregates M1 and M2, and cash in Algeria over the period 1979–2019, and study its long-run stability. We show that the transaction motive is significant for all three aggregates, especially for the demand for cash, reflecting the weight of informal economy “practices”. The elasticity of the scale variable is very close to unity for M2 and M1, and even equal to unity for cash demand (1.006). The elasticity of inflation is also significant for all three aggregates, although its level is higher in the case of cash demand (􀀀 6.474). Despite the persistence of certain financial repression mechanisms, interest rate elasticity is significant for all three aggregates, but higher for M1 and cash. The same observation is made for elasticity of the exchange rate, reflecting the effect of monetary substitution, especially for M1 and cash. Finally, our study concludes that the demand for money in terms of M1 remains stable, the same observation being confirmed for the M2 aggregate. However, the demand for fiat currency proves not to be stable. The consequences for the optimal design of monetary policy in Algeria are clearly stated.

This paper models a single liner service design and operations problem. The model selects the ports to be included, their sequence, the sailing speed of vessels, the number of vessels and the amounts of cargo to transport by the service. The objective is to maximise profit. First, a relaxation with a mixed-integer nonlinear programming (MINLP) formulation is proposed. We show how to obtain the optimal speed value. Once this value is obtained, the mathematical programming formulation becomes a mixed-integer linear program (MILP). Then, a two-step exact algorithm is presented to solve the problem. Using real data, the optimal solution was found in less than 1 min for small-size problems and in few hours for relatively large-size problems. More tests were carried out on randomly generated data sets with up to 25 ports. The results of these tests are rather promising, and they enabled us to identify the performance limits of the algorithm.

Chinese small and medium-size enterprises (SMEs) in the textile industry adapt and reshape their business models to cope with the environmental changes resulting from increasing labor costs and decreases in profits. Comparing with big firms, SMEs face more challenges when renewing their business operations. Reactions of SMEs are influenced by the extent of changes in the business model renewal process. The renewal of the business model includes resource configuration, updating purchasing and distribution channels, refining market segments, and rebuilding brands.

  • Flichy de La Neuville Thomas. Lessons from Applying Sanctions and Blockades. Review of Business and Economics Studies. 2021;9(4):23-31.

From the geo-economic standpoint, a power may avail itself of a spectrum of constraining measures against a hostile or dangerous nation — measures ranging from sanctions, boycotts to embargos and blockades, which last represent the ultimate form of economic pressure to which an adversary may be subjected. Because they are an extreme type of economic banishment, their imposition reveals the physiognomy of the power struggle; and, because they obstruct the free flow of goods, they also appear to be an ephemeral anomaly within the Liberal world order. Yet, their incumbency in the game is a reflection of geo-economic complexity. Whether enacted to great fanfare or not, blockades freeze some transactions while generating business opportunities elsewhere. And while an activity momentarily stilled in one zone may be reshaped to the advantage of another, blockades still allow their instigators to zero in on key sectors of the enemy’s economy without endangering the country’s survival. Thus, we can see blockades as an economic and military measure serving imperial ends. This essay succinctly reviews the history of famous blockades and garners the core economic lessons one may learn from them.

In this paper, we empirically analyse the performance of five gold-backed stablecoins during the COVID-19 pandemic and compare them to gold, Bitcoin and Tether. In the digital assets’ ecosystem, gold-backed cryptocurrencies have the potential to address regulatory and policy concerns by decreasing volatility of cryptocurrency prices and facilitating broader cryptocurrency adoption. We find that during the COVID-19 pandemic, gold-backed cryptocurrencies were susceptible to volatility transmitted from gold markets. Our results indicate that for the selected gold-backed cryptocurrencies, their volatility, and as a consequence, risks associated with volatility, remained comparable to the Bitcoin. In addition, gold-backed cryptocurrencies did not show safe-haven potential comparable to their underlying precious metal, gold.

This paper analyses herding in cryptocurrency markets in the time of the COVID-19 pandemic. We employ a combination of quantitative methods to hourly prices of the four most traded cryptocurrency markets – USD, EUR, JPY and KRW – for the period from 1st January 2019 to 13th March 2020. While there are several strong theoretical reasons to observe the ‘‘black swan” effect on cryptocurrency herding, our results suggest that COVID-19 does not amplify herding in cryptocurrency markets. In all markets studied, herding remains contingent on up or down markets days, but does not get stronger during the COVID-19. These results are important for cryptocurrency investors and regulators to enhance their understanding of cryptocurrency markets and the financial effects of the COVID-19 pandemic.

Information systems literature suggests that reputation is the main judgment form that captures user-related information online. Drawing on social judgment literature, we contend that a user’s online characteristics and past actions are not all reputation-based, but also legitimacy-based, and that transaction stake determines whether users will use reputation or legitimacy judgment to evaluate other users. Using Airbnb, we show that level of stake in a transaction determines the judgment form (reputation or legitimacy) that guests resort to when evaluating a host. Moreover, we find that providing extensive information on a host to potential guests in low-stake transactions is counterproductive.

Why do organizations develop and execute social media initiatives to create business value? This study addresses this prominent and critical research question for IS research on the business value of social media. Drawing on the institutional theory, we argue that mimetic, coercive, and normative pressure persuade organizations to use social media to improve marketing performance. We test our core proposition and theory-driven research model using data collected from a sample of leading Chinese agribusinesses. We find that coercive and mimetic pressure play pivotal roles in motivating organizations to use social media. We also discover that social media usage improves marketing performance and that the agribusiness market uncertainty plays a positive reinforcing role in the positive effect of social media usage on marketing performance. Thus, this paper contributes to IS research with an eloquent theoretical explanation and strong empirical evidence on why organizations deploy social media initiatives to improve their marketing activities and performance and the higher business value of social media under greater agribusiness market uncertainty.

Ethical leadership and environment specific discretionary behaviour: The mediating role of green human resource management and moderating role of individual green values. Canadian Journal of Administrative Sciences/Revue canadienne des sciences de l’administration, 38( 4), 442– 459

This study examines the mediating role of green human resource management between ethical leadership and employees’ citizenship behavior towards  the environment with the moderating effect of individual green values. We collected data from 589 MBA executive students with one‐year of experience working in various organizations at two different times using a questionnaire based survey method. Applying structural equation modeling to the results confirmed a direct effect of ethical leadership on employees’ citizenship behavior towards the environment and an indirect effect through green human resource management. Further, individual green value strengthened the association between green human resource management and employees’ environmentally conscious citizenship behavior. Our study contributes to social learning and supply value‐fit theory and has implications for management.

  • Liu, Yi and Han-fen Hu (2021) Digital-Free Tourism Intention: A Technostress Perspective. Current Issues In Tourism, Vol. 24  No. 23, pp. 3271-3274

Digital-free tourism limits tourists’ access to information and communication technologies during vacation. It is an emerging trend but tourists’ motivation to take digital-free tourism has not been fully understood. Anchoring on technostress literature, this study examines the effects of the exhaustion from workplace information technology and off-work social network services on tourists’ intention to take digital-free tourism. Survey data involving 300 full-time working individuals show that both techno-exhaustion and social-networkservices- exhaustion have positive impacts on tourists’ digital-free tourism intentions. It contributes to the literature by introducing technostress related constructs in understanding tourists’ digital-free tourism intentions.

We study the interdiction of smuggling network that arranging the activities of the police in order to successfully interdict criminals in smuggling goods. This work contributes to the literature of maximum flow network interdiction problems by addressing asymmetric information, uncertain conditions, multi commodity, and with multiple sources (origins) and sinks (destinations). Information Asymmetry realistically occurs due to incomplete information of interdictor (police) and operator (smuggler) about each other’s performance, which is adapted from the real-world condition. We propose two mixed-integer programming models by reformulating a Min–Max bi-level mathematical model. In the first model, the type of interdiction is discrete (zero and one), while in the second model, the interdiction is assumed continuous, meaning that the partial interdiction is possible. The asymmetry type of the smuggler’s information towards the police have formulated through a linear function while the asymmetry of the police information to the smuggler is formulated using an uncertain parameter through a two-stage stochastic programming framework. To solve the first model, an innovative exact hybrid method is proposed combining of a Decomposition Method and Progressive Hedging Algorithm (DM-PHA). An augmented Karush-Kuhn-Tucker (KKT) method is also used to solve the second model. Several sensitivity analyses are then conducted, and the results demonstrate the applicability and effectiveness of the proposed models as well as the solving approach. It is also shown that the proposed models can be used as a suitable approach in uncertain environment and under asymmetric information to determine the optimal interdiction decisions of police to prevent further smuggling.

  • Canan Yildirim, Adnan Kasman, Fazelina Sahul Hamid (2021) Impact of foreign ownership on market power: Do regional banks behave differently in ASEAN countries? Economic Modelling, Volume 105, 2021, 105654

The change in crossborder financial intermediation and rise in regional banking have consequences for competitive conduct in emerging countries’ banking markets. Using data from the Association of Southeast Asian Nations countries’ banks during 2011–2018, we examine the nexus between foreign ownership and banks’ market power by controlling for the heterogeneity of foreign banks concerning their countries of origin (advanced vs. emerging and regional vs. nonregional). We find that the increasing presence of foreign banks from advanced countries is associated with lower bank market power because of higher marginal costs and lower price–cost margins of the domestic banks. However, the increasing presence of emerging countries’ banks is associated with higher bank market power because of lower marginal costs and prices of domestic lenders. Our findings have implications for policies regarding bank competitiveness and promoting regional banking integration because domestic banks conduct differently under increased participation levels of advanced and emerging country foreign banks.
