Labor Market Institutions and Gender Differences in Wage Inequality.

In this paper, we present graphical and quantitative evidence on the important role played by changes in labor market institutions on the rise in wage inequality in the United States during the 1980s. We show that the decline in the real value of the minimium wage and in the rate of unionization explains over a third of the rise in inequality among men.

Market failure, inequality and redistribution

We consider the following question: does market failure justify redistribution? We argue that the general answer to this question is no, in the sense that policies for correcting market failures do not aim at producing a "desirable" income distribution. This follows from the fact that, by construction, market failure is a deviation from "efficiency" that does not involve any notion of a desirable distribution of welfare (or income). However, there are special cases where a "corrective measure" involving redistribution can offset a market failure, so this can provide a form of efficiency- based justification for redistribution.

Essais en économie de l’environnement et des ressources naturelles sous incertitude

Cette thèse comprend trois essais en économie de l’environnement et des ressources naturelles sous incertitude. Le premier essai propose un modèle de jeu différentiel qui analyse la pollution globale à travers la quête à l’hégémonie politique entre pays. Le second essai utilise des données boursières pour estimer une version stochastique de la règle de Hotelling et ainsi inférer sur le rôle des ressources naturelles non renouvelables dans la diversification du risque. Le troisième essai montre comment la prise en compte des perspectives futures modifie la règle de Hotelling dans un contexte de diversification du risque.
