Ce travail fait suite au rapport intitulé « Appels d'offres et enchères ouvertes : Enjeux de design et propositions » rédigé par Y. Richelle, J. Robert et R. Gérin-Lajoie qui, d'une part, met en évidence les problèmes liés à l'utilisation des procédures actuelles et, d'autre part,...

We present an experiment in which we test for the effect of participating in a social exchange exercise on revealed risk and ambiguity preferences. In our experiments, subjects make choices over lotteries that reveal their risk and ambiguity preferences. They then participate with a small group...

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...

We provide an experimental analysis of competitive insurance markets with adverse selection. Our parameterized version of the lemons' model (Akerlof 1970) in the insurance context predicts total crowding out of low-risks when insurers offer a single full insurance contract. The therapy proposed...

The introduction of a centralized institution for trading production rights in quota-regulated agricultural sectors can dramatically improve the flow of information among market pareticipants and increase efficiency. On the other hand, prevailing conditions in these small markets can provide...

We experimentally test whether risk aversion or ambiguity aversion can explain decisions in a learning-by-doing game. We first measure subjects' preferences toward risk and ambiguity, and then use these measures to predict behavior in the game. We find that ambiguity averse subjects pay more...

Subjects submitted strategies for playing a public good game. The strategies interacted with each other in a computer simulation. They could be revised and resubmitted for a second and a third simulation round. The strategies' average contribution to the public good increased from one simulation...

This paper makes an attempt at testing the external validity of corruption experiments by moving from the lab in a developed country, to where it matters the most, the field in a developing country. In our experiment a candidate proposes a bribe to a grader in order to obtain a better grade. We...

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 paper studies budget processes, both theoretically and experimentally. We give a sufficient condition for top-down and bottom-up budget processes to have the same voting equilibrium. Furthermore, at a voting equilibrium, it is not always true, as often presumed, that a top-down budget...
