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,...

Ce rapport présente les résultats d'une expérience en laboratoire simulant l'impact de la Prime au travail introduite en janvier 2005 par le gouvernement du Québec. Plus précisément, il s'agit d'analyser l'effet de cette prime sur l'effort au travail des familles monoparentales et des...

Cet article présente les résultats de recherches en économie expérimentale visant à mesurer les propensions à payer d'un échantillon de consommateurs français pour des yaourts fonctionnels. Nous mesurons l'impact de l'information concernant les caractéristiques fonctionnelles des...

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...

Currently, economic environment is unbalanced, it has become changing and uncertain. In this context, a formal analysis is not sufficient to make a decision. Indeed, decision makers meet difficulties to produce sophisticated tools in a way as fast as the environment evolution. The various...

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...
