The World Trade Center attack has shed light on the urgent need to implement preventing measures against terrorism and to enhance cooperation in the global security system for all countries. However, international coordination cannot be taken for granted. It is often ineffective and likely to...

Les consommateurs prennent leurs décisions alimentaires en fonction des informations qu’ils reçoivent et de leurs caractéristiques individuelles. Dans le cadre d’une expérience associant économie expérimentale et évaluation sensorielle, nous mettons en parallèle l’évaluation...

This paper provides a general framework that accounts for the decay of the average contribution observed in most experiments on voluntary contributions to a public good. Each player balances her material utility loss from contributing with her psychological utility loss of deviating from her...

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...

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...

We study the relationship between inequality and inter-groups conflicts (riots), focussing on social inequality. Disadvantaged societal groups experience discrimination and thus have limited access to some social and labour resources like education or employment. First, we experimentally...
