An exploratory study of the adoption of artificial intelligence in Burgundy's wine industry
No full textInternational audienceThe objective of this exploratory study is to identify which factors enable or inhibit artificial intelligence adoption within the wine sector and specifically for the Burgundy region. Findings revealed that the winegrower's adoption intention could be assessed according to (a) perceived benefits, (b) organizational readiness, and (c) external pressure
The nexus between policy uncertainty, sustainability disclosure and firm performance
No full textInternational audiencePolicy 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
The impact of COVID-19 induced panic on the return and volatility of precious metals
No full textInternational audienceWe use TVP-VAR approach to analyze the connectedness between the COVID-19 induced global panic index (GPI) and precious metals return and volatility. We find evidence of positive connectedness between the GPI and precious metals with GPI being a shock transmitter and precious metals, especially gold, being net receivers. While silver shows the highest resistance to shocks, platinum and palladium present a time varying transmission pattern. Our results refute the safe-haven property of precious metals during the COVID-19 outbreak, with the exception of silver
Antecedents and consequences of students’ attitudes towards internationally accredited business schools: a signalling theory perspective
No full textInternational audienceIn this research we attempt to empirically validate a model – using signalling theory – that explains important antecedents and consequences of students’ attitude towards internationally accredited business schools. Using a quasi-experimental design, we collected data from undergraduate students of eight countries across four scenarios. The results of our overall model suggest that students’ concern for achievement is strongly correlated with their attitude towards international accredited schools. Students’ attitude towards accredited business school is a strong predictor of school reputation and legitimacy and both influence their support intentions. The study also indicates that multiple accreditations do not moderate the relationships in our proposed model
Does corporate environmentalism affect corporate insolvency risk? The role of market power and competitive intensity
No full textInternational audienceLittle 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
Can impostors thrive at work? The impostor phenomenon's role in work and career outcomes
No full textInternational audienceThis 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
Deriving value or risk? Determinants and the impact of emerging market banks’ derivative usage
No full textInternational audienceThis 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
Intergenerational hybrid products in periods of discontinuous change
No full textInternational audiencePurpose This study examines the role of hybrid products employed in companies' innovation strategy within three American industrial sectors: tires, typewriters and photography cameras. Design/methodology/approach The authors selected historical cases that enabled us to present the role of hybrid products in periods of discontinuous change. Different sources are employed in this study: papers, books, cases, working papers, videos, manuals and product catalogues, companies' annual reports, company websites, advertising, collectors' websites and museums, in addition to press and other media reports. Findings The authors’ historical case analysis points to two forms of hybrid products. (1) Exploitation-hybrid, which incorporates significant elements from the existing dominant design and aims at extending the revenue-generating opportunities of the existing products. (2) Exploration-hybrid, which works as an offensive strategy, as the firm uses the exploration-hybrid to promote a gradual and controlled adoption of new technology by reducing risks and the cost of change for the customer. Research limitations/implications The authors’ proposed definitions strengthen the idea that hybrids are not only a reflection of organizational inertia (exploitation-hybrid). Hybrids can also mean a more proactive stance in the strategy of developing and adopting new technology (exploration-hybrid). Originality/value This study acknowledged hybrid products as a learning instrument that materialized the organizational ambidexterity, favoring at the same time exploitation, generally attributed to organizational inertia, and the exploration of new segments of customers or the use of new technologies
Business model renewal and environment changes: Insights of Chinese textile industry
No full textInternational audienceChinese 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
From dotcom to Covid-19: A convergence analysis of Islamic investments
No full textInternational audienceThis 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
