L’économie comportementale et l’économie expérimentale ont connu un formidable essor au cours des dernières décennies. L’objectif de cet article est de présenter, au travers d’un cadre général d’analyse et d’exemples d’applications, l’intérêt de l’économie...

This paper tests whether utility is the same for risk and for uncertainty. This test is critical for models that capture ambiguity aversion through a difference in event weighting between risk and uncertainty, like the multiple priors models and prospect theory. We present a new method to...

Ces trente dernières années ont connu un formidable développement d’un nouveau champ de l’analyse économique, l’économie comportementale. Initiée et fondée en partie sur les méthodes de l’économie expérimentale, ce nouveau champ disciplinaire a profondément renouvelé la...

It is well-known that expected utility (EU) has empirical deficiencies. Prospect theory (PT) has developed as an alternative with more descriptive validity. However, PT’s full function had not yet been quantified in the health domain. This paper is therefore the first to simultaneously measure...

This paper examines couple time preferences by reporting the results of an ex- periment based on the elicitation of nearest equivalent values. Decisions involving delayed outcomes are studied for each of the two partners individually and for the couple. This allows for a direct comparison...

This paper studies the effect of learning new information on decision under uncertainty.Using ambiguity models, we show the effect of learning on beliefs and ambiguity attitudes. We develop a new method to correct beliefs for ambiguity attitudes and decompose ambiguity attitudes into pessimism...

We present new evidence from the lab on the outcomes resulting from collective and individual decisions over time. We combined static and longitudinal methods to test four conditions on individual and collective time preferences: impatience, stationarity, age independence, and dynamic...

In this article, we use a stylized model of the labor market to investigate the effects of three alternative and well-known bargaining solutions. We apply the Nash, the Egalitarian and the Kalai-Smorodinsky bargaining solutions in the small firm’s matching model of unemployment. We first show...

In this note, we extend the traditional search and matching framework to take account of the different levels at which negotiations may take place. We show that, in the absence of any distortion, sector-level bargaining ought to be less efficient than bargaining taking place at the other levels....
