Il existe une économie politique du redoublement dont il faut essayer de mettre à jour quelques ressorts : le redoublement est une modalité particulière de la gestion du système éducatif qui présente des coûts et des bénéfices et dont l’efficacité est mise en question depuis de...

La théorie micro-économique entend réduire au maximum le nombre d'hypothèses sur les goûts nécessaire à la construction des modèles de demande. Néanmoins aucun modèle n'atteint jamais la généralité absolue et certaines hypothèses sont même devenues tellement usuelles qu'on ne...

We develop an empirical search-matching model with productivity shocks so as to analyze policy interventions in a labor market with heterogeneous agents. To achieve this we develop an equilibrium model of wage determination and employment, which is consistent with key empirical facts. As such...

We propose a search-matching model of the marriage market that extends Shimer and Smith (2000) to allow for labor supply. We characterize the steady-state equilibrium when exogenous divorce is the only source of risk. The estimated matching probabilities that can be derived from the steady-state...

Postel-Vinay and Robin’s (2002) sequential auction model is extended to allow for aggregate productivity shocks. Workers exhibit permanent differences in ability while firms are identical. Negative aggregate productivity shocks induce job destruction by driving the surplus of matches with low...

We compare earnings inequality and mobility across the U.S., Canada, France, Germany and the U.K. during the late 1990s. A flexible model of earnings dynamics that isolates positional mobility within a stable earnings distribution is estimated. Earnings trajectories are then simulated, and...

In this paper, we document whether and how much the equalizing force of earnings mobility has changed in France in the 1990’s. For this purpose, we use a representative three-year panel, the French Labour Force Survey. We develop a model of earnings dynamics that combines a flexible...

The aim of this paper is to provide simple nonparametric methods to estimate finitemixture models from data with repeated measurements. Three measurements suffice for the mixture to be fully identified and so our approach can be used even with very short panel data. We provide distribution...

We develop and estimate an equilibrium job search model of worker careers, allowing for human capital accumulation, employer heterogeneity and individual-level shocks. Monthly wage growth is decomposed into the contributions of human capital and job search, within and between jobs. Human capital...
