Ce papier analyse la dynamique des réseaux d'alliances et plus particulièrement la division du travail qui s'opère entre les différents types d'acteurs (Grands Groupes Industriels, Entreprises Spécialisées de Biotechnologies et Instituts de Recherche Académique) qui interviennent dans...

We present results of a household-level survey on behaviors regarding refuses in the home waste-waters network. Interpreting survey results in a panel-data logit results show that most socio-economic and public good-related respondent's characteristics do not play a significant role in...

This paper develops a simple model to explain two stylised facts about immigration. First, some countries have a low ratio of migrants in their population, while other wealthy countries have a high number of migrants. In fact such migrants are of the same order of magnitude as their domestic...

The folk theorem characterizes the (subgame perfect) Nash equilibrium payoffs of an undiscounted or discounted infinitely repeated game - with fully informed, patient players - as the feasible individually rational payoffs of the one-shot game. To which extent does the result still hold when...

We present the results of an experiment that explores the sanctioning behavior of individuals who experience a social dilemma. In the game we study, players choose contribution levels to a public good and subsequently have multiple opportunities to reduce the earnings of the other members of the...

The purpose of this article is to provide an economic analysis of the relationship between economic integration and political fragmentation. This follows previous contributions from Alesina et al (2000), Casella (2001, Casella and Feinstein (2002), or Leite-Monteiro and Sato (2003). We go a step...

The purpose of this note is to correct an error in the seminal article on secession by Buchanan and Faith (1987). In their paper, Buchanan and Faith neglected an important effect: political separation affects markets and consequently individual private incomes.

We address in this paper the issue of leadership when two governments provide public goods to their constituencies with cross border externalities as both public goods are valued by consumers in both countries. We study a timing game between two different countries: before providing public...

We develop an economic model of association based on voluntary contributions. Different equilibria corresponding to the different modes of formation of associations are analyzed and the results are compared with existing empirical literature. The main contribution consists in formalizing the...

We run a series of experiments in which subjects have to choose their level of contribution to a pure public good. Our design differs from the standard public good game with respect to the decision procedure. Instead of deciding simultaneously in each round, subjects are randomly ordered in a...
