Ethical preferences for influencing superiors: A 41-society study
2009
With a 41-society sample of 9990 managers and professionals, we used hierarchical linear modeling to investigate the impact of both macro-level and micro-level predictors on subordinate influence ethics. While we found that both macro-level and micro-level predictors contributed to the model definition, we also found global agreement for a subordinate influence ethics hierarchy. Thus our findings provide evidence that developing a global model of subordinate ethics is possible, and should be based upon multiple criteria and multilevel variables.

US deficit sustainability revisited: A multiple structural change approach
2008
In this article we re-examine the long-run sustainability of US budget deficits, using Bai and Perron's multiple structural change approach. While the deficit would have been weakly sustainable over the full sample (1947:1–2005:3), strong sustainability would appear only between January 1982 and February 1996.
Inequalities in the efficiency of the banking sectors of the European Union
2002
The aim of this study was to analyse the inequalities of cost and profit efficiency existing in the banking sectors of the European Union, and the origins of the inequalities observed. The decomposition of the Theil index shows that on the cost side the greatest differences within groups occur when the total sample is divided into institutional groups (commercial banks, saving banks, co-operative banks and other banks), the country effect and the type of productive specialization being more important in explaining the differences between groups. In profit efficiency, there are great differences between countries, but none between specialization clusters.
Sampling properties of the Bayesian posterior mean with an application to WALS estimation
2022
Many statistical and econometric learning methods rely on Bayesian ideas, often applied or reinterpreted in a frequentist setting. Two leading examples are shrinkage estimators and model averaging estimators, such as weighted-average least squares (WALS). In many instances, the accuracy of these learning methods in repeated samples is assessed using the variance of the posterior distribution of the parameters of interest given the data. This may be permissible when the sample size is large because, under the conditions of the Bernstein--von Mises theorem, the posterior variance agrees asymptotically with the frequentist variance. In finite samples, however, things are less clear. In this pa…
Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes
2022
Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021.

Impacts of sovereign risk premium on bank profitability: Evidence from euro area
2021
We analyse the effects of low and negative interest rates and sovereign risk premium on bank profitability among 154 Eurozone banks during the period 2005–2019. In contrast to some of the results in the previous literature, we find that the euro area banks have not suffered too much from the extremely low and negative interest rate era regarding their net interest margins. However, the overall profitability has lowered clearly during the sample period, and the sovereign risk premium has a robust negative effect on all the overall profitability measures, both with risk-adjustment and without it, but it seems to have an increasing effect on the degree of wholesale funding and loan loss provis…
Japan's FDI drivers in a time of financial uncertainty. New evidence based on Bayesian Model Averaging
2021
En este artículo analizamos los determinantes del stock de FDI saliente de Japón para el período 1996–2017. Este período es especialmente relevante ya que abarca un proceso de creciente globalización económica y dos crisis financieras. Para ello, consideramos un amplio conjunto de variables candidatas basadas en la teoría, así como en análisis empíricos previos. Nuestra muestra incluye un total de 27 países anfitriones. Seleccionamos las covariables utilizando una metodología basada en datos, el análisis Bayesian Model Averaging (BMA). Además, también analizamos si estos determinantes cambian según el grado de desarrollo (emergentes vs desarrollados) o las áreas geográficas (UE vs Asia Orie…
Sharing economy and incumbents' pricing strategy: The impact of Airbnb on the hospitality industry
2019
Abstract In this paper, we examine how the emergence of sharing economy platforms influences incumbents' price responses. Grounding on the literature on price reactions to new entrants and on the unique characteristics of the sharing economy, we argue that the effect of the penetration of the sharing economy on incumbents' prices is not straightforward, and actually depends on the type of incumbents as well as certain product/service offer characteristics. Indeed, relying on a large sample of hotel price offerings from the Italian market, we find that the effect of the growing relevance of the sharing economy (exemplified by Airbnb) on incumbents' prices depends on the type of incumbents (l…
“Don't try to teach me, I got nothing to learn”: Management students' perceptions of business ethics teaching
2019
[EN] Interest is growing towards including business ethics in university curricula, aiming at improving ethical behaviour of future managers. Extant literature has investigated the impact of ethics education on different ethics-related students' cognitive and/or behavioural outcomes, considering variables related to training programmes and students' demographic aspects. Accordingly, we aim at assessing students' understanding of business ethics issues, by focusing on the differences in students' perceptions depending on gender, age, work experience, and ethics courses taken. Testing our hypotheses on a sample of 307 management students at a Polish university, and controlling for social desi…
Efficiency of French privatizations: a dynamic vision
2004
The program of French privatizations is one of the principal worldwide programs as for the volume of the equity issues. A reading of the process of privatization through the corporate governance theory resulted in working out a model making it possible to take into account, on the one hand, the time dimension of the process of privatization, on the other hand, the contextual, organizational, governance and strategic variables which influence this process. After having replicated a certain number of traditional tests, we carried out a test of this model on a sample of 19 French privatized firms and on a seven years horizon, which made it possible to obtain the following conclusions. The favo…
