The brain drain has long been viewed as a serious constraint on poor countries development. However, recent theoretical literature suggests that emigration prospects can raise the expected return to human capital and foster investment in education at home. This paper takes advantage of a new...

The adoption of gender quotas in party lists has been a voluntary decision by many parties in many countries, and is now a subject of discussion in many others.

Cet article montre que dans le cadre d’un modèle d’appariement, la coexistence d’emplois de durées du travail différentes peut s’expliquer par des intensités capitalistiques propres à certaines activités. les firmes sont supposées financer seules le capital nécessaire à la...

A social choice correspondence (SCC) is virtually implementable if it is ε-close (in the probability simplex) to some (exactly) implementable correspondence. Abreu and Sen (1991) proved that, without restriction on the set of alternatives receiving strictly positive probability at equilibrium,...

In the spirit of Arrow (1962), we examine, in an oligopoly model with horizontally differentiated products, how much a firm is willing to pay for a process innovation that it would be the only one to use. We show that different measures of competition (number of firms, degree of product...

We study information revelation in markets with pairwise meetings. We focus on the one sided case and perform a dynamic analysis of a constant entry flow model. The same question has been studied in an identical framework in Serrano and Yosha (1993) but they limit their analysis to the...

We analyze whether and how the fact that products are not sold on free, public, platforms but on competing for-profit platforms affects sellers’ investment incentives. Investments in cost reduction, quality, or marketing measures are here to joint and coordinated efforts by sellers. We show...
