Several online market sites, such as eBay, have implemented reputation management mechanisms in order to improve cooperation. In this article, we aim at investigating the emergence of trust and cooperation in presence of reputation mechanism. In a series of experiments based on the trust game...

Overcontribution in experiments on voluntary contribution to a public good has not yet received a fully satisfactory explanation. In those experiments, subjects cooperate, in contradiction with the game-theoretic prediction. In contrast, in oligopoly-experiments and common pool resource...

French Abstract: Nous discutons de quelques développements récents en économie expérimentale sur la relation entre la loi et les normes sociales dans la détermination des comportements. Dans l'approche traditionnelle de l'analyse économique du droit, l'effectivité des lois repose...

Nous étudions expérimentalement le comportement de sujets confrontés, dans une population, à une multiplicité de jeux du dilemme du prisonnier, suivant que les interactions sont bilatérales ou multilatérales. Nous observons, (i), une coopération significativement supérieure en cas de...

We compare the experimental results of three stag-hunt games. In contrast to Battalio et al.(2001), our design keeps the relative riskiness of the two strategies at a constant level as the optimisation premium is increased. Furthermore, we also test the effect of a decrease of the relative...

The explanation of social inequalities in education is still a debated issue in economics. Recent empirical studies tend to downplay the potential role of credit constraint. This article tests a different potential explanation of social inequalities in education, specifically that social...

This study experimentally tests whether a modification to the centralized quota sales system is capable of lowering the price of the milk quota in Québec, while at the same time minimizing the negative impacts on the auction's efficiency. This modification consists of applying two treatments on...

We make use of experimental economics to examine how people adjust their supply of work effort in response to a variation in tax rates. Participants are paired in the experiment. In each pair, one participant randomly chosen has to exert an effort and is taxed to the benefit of the other...

The influence of relative wealth on fairness considerations is analyzed in an ultimatum game experiment in which participants receive large and widely unequal initial endowments. Subjects initially demonstrate a concern for fairness. With time however, behavior becomes at odds with both subgame...
