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...

The eBay Feedback Forum is claimed to be a crucial component of the success of eBay. Many empirical studies have found that this feedback system exerts a deterrent effect on the opportunistic behavior the Internet's anonymity may incite buyers and sellers to adopt. The feedback system in place...

A conjecture of Laffer, which had considerable influence on fiscal doctrine, is that tax revenues of a Leviathan state eventually decrease when the tax rate exceeds a threshold value. We conduct a real effort experiment, in which a "worker" is matched with a non-working partner, to elicit the...

[fre] La littérature économique a beaucoup discuté les fondements microéconomiques de la décision de choisir le statut d' « indépendant ». Plusieurs études empiriques soulignent le rôle déterminant de la situation financière, du niveau d'éducation et de l'environnement familial....

This paper focuses on decision making under risk, comparing group and individual risk preferences in a lottery-choice experiment. In the individual treatment, subjects make choices individually; in the group treatment, each subject placed in a group made lottery choice via voting. In the choice...

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...

This paper addresses the effects of peer pressure in work teams. Many empirical studies have shed light on the efficiency of peer pressure. Peer pressure can be defined as mechanisms of mutual monitoring and sanction established within a group of agents by the agents themselves in order to...

This experiment evaluates various systems of taxation on the number of real tasks performed by participants and in terms of fiscal income generated to help government in its redistributive goal. The first treatment concerns a proportional system of taxation. The second treatment considers an...

Noncompliance is a quantitatively important phenomenon that affects significantly revenue source for state governments. This phenomenon raises challenging questions about the determinants of tax reporting and also about the appropriate design of a tax system: how many resources should be devoted...

A conjecture of Laffer, which had considerable influence on fiscal doctrine, is that tax revenues of a Leviathan state eventually decrease when the tax rate exceeds a threshold value. We conduct a real effort experiment, in which a worker is matched with a non-working partner, to elicit the...
