Internet is a very attractive technology for the implementation of experiments, both in order to obtain larger and more diverse samples and as a field of economic research in its own right. This paper reports on an experiment performed both online and in the laboratory, designed to strengthen...

Introduced by Samuelson (1975), the Serendipity Theorem states that the competitive economy will converge towards the optimum steady-state provided the optimum population growth rate is imposed. This paper aims at exploring whether the Serendipity Theorem still holds in an economy with risky...

Cet article a pour but de comprendre les différences de productivité observées en France entre les hôpitaux publics, les hôpitaux privés à but non lucratif (PSPH) et les cliniques privées. Nous examinons s'il existe une influence de la composition de la patientèle et des séjours sur la...

A game with precedence constraints is a TU game with restricted cooperation, where the set of feasible coalitions is a distributive lattice, hence generated by a partial order on the set of players. Its core may be unbounded, and the bounded core, which is the union of all bounded faces of the...

Les premières expériences de marché réalisées par Vernon Smith [1962] ont mis en évidence l'importance des institutions de marché pour l'efficacité des échanges. Ces institutions organisent la communication d'information entre les acteurs du marché et structurent les incitations...

Economic theory claims that contracts renegotiation prevents from reaching the informationally constrained efficient solution that could have been obtained under full commitment. Assessing the cost of renegotiation compared to the full commitment scenario still remains an open issue from an...

Alors que de nombreux travaux ont été effectués à propos de l'effet de l'assurance santé sur la demande de soins, l'effet de l'urbanisation, du processus d'industrialisation et les changements de l'offre de soins n'ont reçu jusqu'ici que peu d'attention. Les données mobilisées...

An element of the possibly unbounded core of a cooperative game with precedence constraints belongs to its bounded core if any transfer to a player from any of her subordinates results in payoffs outside the core. The bounded core is the union of all bounded faces of the core, it is nonempty if...

Economic analysis is increasingly addressing long-term issues (such as global warming) that require a dynamic baseline for the world economy. In this article, we develop a three-factor (capital, energy, labour) macroeconometric (MaGE - Macroeconometrics of the Global Economy) model, and project...
