We study the treatment effect of grade retention using a panel of French junior high-school students, taking unobserved heterogeneity and the endogeneity of grade repetitions into account. We specify a multistage model of human-capital accumulation with a finite number of types representing...

In this paper we investigate the recent fall in unemployment, and the rise in part-time work and labour market participation amongst prime-aged Germans. We show that unemployment fell because the Hartz reforms induced a large fraction of the long-term unemployed to deregister as jobseekers....

Postel-Vinay and Robin' (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...

This paper studies under which conditions a cross-sectional regression yields unbiased estimates of the parameters of an individual dynamic model with fixed effects and individual-specific responses to macro shocks. We show that the OLS estimation of a relationship involving non stationary...

<p><p>We study linear factor models under the assumptions that factors are mutually independent and independent of errors, and errors can be correlated to some extent. Under factor non-Gaussianity, second to fourth-order moments are shown to yield full identification of the matrix of factor loadings....</p></p>

In this paper we present and estimate a synthesis of previous equilibrium search models: allowing for continuous distributions of workers opportunity costs of employment, as well as firms' productivities. The model allows for on-the-job search, and we assume that job offer arrival rates for...

In this article we develop an equilibrium search model with a continuous distribution of firm productivity types within a given labor market. We characterize equilibrium, derive expressions for the endogenous equilibrium wage distributions, and characterize the set of wage distributions that can...

L'article étudie l'impact de la structure économique locale sur la croissance locale de l'emploi. Cette croissance de l'emploi est décomposée en croissance interne (la croissance de la taille des établissements) et croissance externe (la création de nouveaux établissements). Les auteurs...
