Is the learning community of economics and accounting effective? Empirical assessment of class achievements

Learning communities are increasingly used at colleges and universities, as one of the goals of a learning community is to increase interaction among students and teach them how to apply knowledge. The goal of this research is to assess the learning community of the economics and accounting students in their class performance measured by class grades. By controlling individual characteristics (e.g., gender, high school performance, First Year Experience program) and class-related characteristics (e.g., instructor and major), the authors found that the learning community of economics and accounting, which is organized into both economics and accounting classes on a back-to-back basis, is no more effective for class grades than for non–learning community students.     

Store loyalty, bargaining power and the private label production issue

One of many explanations offered for the rise of private labels(PLs) is that they increase the bargaining power of the retailer.The prior question of the PL production assignment has not beenanalysed in an economic framework. The retailer can either entrustthe production of his PL to the national brand (NB) manufacturerat a low unit cost, with the disadvantage that both products(NB and PL) are held by the same agent, or he can choose a firmfrom the competitive fringe with a higher unit production cost.In a framework where loyalty (presence of store-switching andbrand-switching consumers) and bargaining strength count, weshow that the retailer will assign his PL production to theNB manufacturer when the latter's bargaining power is low. However,a higher consumer loyalty for the NB can reverse the retailer'sdecision.     

European competition policy modernization: From notifications to legal exception

Council Regulation (EC) 1/2003 came into force in May 2004 and replaced the mandatory notification of agreements by a regime of ex post monitoring. This paper shows that ex post monitoring is the optimal audit regime when the competition authority's probability of error is low. On the other hand, the notification system becomes optimal when the competition authority's probability of error is high. The paper also shows that block exemptions and black list (regimes of per se (il)legality) should be implemented when the agreements’ expected welfare impact is very high and very low, respectively.     

Is it time to reboot welfare economics? Overview

The contributions of economists have long included both positive explanations of how economic systems work and normative recommendations for how they could and should work better. In recent decades, economics has taken a strong empirical turn as well as having a greater appreciation of the importance of the complexities of real-world human behaviour, institutions, the strengths and failures of markets, and interlinkages with other systems, including politics, technology, culture and the environment. This shift has also brought greater relevance and pragmatism to normative economics. While this shift towards evidence and pragmatism has been welcome, it does not in itself answer the core question of what exactly constitutes ‘better’, and for whom, and how to manage inevitable conflicts and trade-offs in society. These have long been the core concerns of welfare economics. Yet, in the 1980s and 1990s, debates on welfare economics seemed to have become marginalised. The articles in this Fiscal Studies symposium engage with the question of how to revive normative questions as a central issue in economic scholarship.     

Fishery externalities and biodiversity: Trade-offs between the viability of shrimp trawling and the conservation of Frigatebirds in French Guiana

Sustainable management of natural resources, and in particular fisheries, must take into account several conflicting objectives. This is the case in the French Guiana shrimp fishery for which profitability objectives imply a reduction in the fishing activity. On the one hand, this fishery has negative externalities on marine biodiversity due to discards. On the other hand, this fishery has positive externalities on the economy of the local community and interestingly enough on a protected seabird species in the area (the Frigatebird that feeds on discards). In this paper, we examine the viability of that system considering two sustainability objectives: an economic objective in terms of the profitability of the fishing activity, and a conservation objective in terms of the Frigatebird population. For that purpose, we have developed a dynamic model of that bioeconomic system and study here the trade-offs between the two conflicting objectives. It provides a means to quantify the necessary give and takes involving the economic and ecological objectives that would ensure a viable management solution. Our study confirms the relevance of the viability approach to address natural resource management issues, which should lead to the development of new tools for the arbitration of conflicting sustainability objectives. In particular, such tools could be used as a quantitative basis for cost–benefit analysis taking into account environmental externalities.     

Fusionen und Übernahmen im Licht der Hybris – Überblick über den Forschungsstand

Although corporate acquisitions are ubiquitous a large number of M&A fails. One explanation for such failure is the hubris hypothesis for corporate takeovers. A decision maker affected with hubris (or overconfidence) will overestimate his abilities in raising potential synergies and is likely to make investment decisions destroying shareholder wealth. The growing literature on CEO hubris proposes various ways to measure hubris. We present these indicators and discuss possible advantages and drawbacks. (71 words)     

The impact of expatriate personality traits on cross-cultural adjustment: A study with expatriates in Japan

While regarded as among the most important factors affecting expatriate cross-cultural adjustment, little focused research with a broad array of personality traits has been conducted. This study draws from the cultural fit hypothesis and the socio-analytic theory to examine the impact of expatriate personality traits through the Multicultural Personality Questionnaire on the general-, interaction-, and work-related facets of cross-cultural adjustment among 181 expatriates in Japan. The results show positive relationships between the personality traits of Open Mindedness and interaction adjustment, Emotional Stability and Cultural Empathy and general adjustment, and Social Initiative and work adjustment.     

Similarities and differences when building trust: the role of cultures

We run an experiment in which students of different European nationalities are matched in groups of five and repeatedly choose with whom within their group they want to play a trust game. Participants observe of each other age, gender, nationality and number of siblings. The region of origin, “North” or “South” is a major determinant of success in the experiment. Participants tend to trust those they trusted before and who trusted them. We do not find evidence of regional discrimination per se. It is only the underlying and significant differences in behavior that translate through repeated interactions into differences in payoffs between the two regions.
