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
The effects of medium and sequence on personality trait assessments in face‐to‐face and videoconference selection interviews: Implications for HR analytics
No full textInternational audienceAbstract Adoption of new technology to support selection interviews may distort the validity of source data in HR analytics, with implications for Artificial Intelligence (AI) algorithms used to assess candidates' personality traits. Using a field experiment with real selection interviews, we compare two common selection interview modes—Face‐to‐Face and videoconference, to evaluate their impact on personality trait assessments. Our findings indicate that candidates scored more highly on agreeableness , openness , extroversion , and conscientiousness, but lower on neuroticism, during a Face‐to‐Face interview compared with videoconference. There was also greater variation in personality ratings when interview sequence commenced with videoconference followed by Face‐to‐Face, compared with the reverse order. Our results suggest that Face‐to‐Face followed by videoconference provide a less distorted assessment of personality traits than videoconference followed by Face‐to‐Face. This study also contributes to practical and academic debates centred on human and AI selection practices and the use of data analytics in HR processes
The role of legitimacy and reputation judgments in users’ selection of service providers on sharing economy platforms
No full textInternational audienceInformation 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
The effects of a “black swan” event (COVID-19) on herding behavior in cryptocurrency markets
No full textInternational audienceThis 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
Market power evolution and convergence in European banking: An empirical note
No full textInternational audienceThis 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
The impact of Islamic banking model and Islamic financial development on bank performance: evidence from dual banking economies
No full textInternational audiencePurpose The purpose of this study is to develop an Islamic Banking Index representing the Islamic banking model and to investigate its impact on the performance of Islamic and conventional banks. This study also analyzes the impact of Islamic financial development on bank performance. Design/methodology/approach The authors collected the data from 23 countries for the period from 2010 to 2018 and developed a composite Islamic Banking Index. The authors applied the generalized method of moments on 3,542 bank-year observations for both Islamic and conventional banks to analyze the impact of the Islamic Banking Index on bank performance. The results of the study are robust to time-fixed effects, country-level time-varying factors and endogeneity issues. Findings The authors found that Islamic Banking Index positively contributes to the return on assets (ROAit) of Islamic banks only. This impact becomes highly significant in countries with comparatively higher Islamic financial development. This finding suggests that the Islamic financial development in a country provides a supportive operating environment to Islamic banks and increases their performance. The authors also found that Islamic Banking Index positively contributes to the return on equity (ROEit) of both types of banks. Practical implications The authors argue that moving away from interest-based products and focusing more on diversified portfolios can boost the performance of both types of banks without increasing their risk levels. Originality/value To the best of the authors’ knowledge, this is the first study that develops a composite Islamic Banking Index based on differentiating factors of the Islamic banking model and investigates the impact of Islamic Banking Index and Islamic financial development on bank performance
An efficient branch and bound algorithm for smoothing the workloads on simple assembly lines
No full textInternational audienceIn this study, we develop a branch and bound solution algorithm to solve the workload smoothing problem. Our algorithm incorporates new formulas for dynamically computing a lower bound on the optimal value of the objective function and for determining the earliest workstations for tasks. It also uses a fast heuristic for computing a good initial upper bound. A comprehensive experimental analysis is conducted in this study. The analysis demonstrates the outstanding performance of the algorithm and its efficiency in solving medium-sized workload smoothing problems
Long-run stability of money demand and monetary policy: The case of Algeria
No full textInternational audienceSince 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
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
