In this paper we apply the statistical framework recently proposed by Imbens (1999) and Lechner (1999) to identify the causal effects of multiple treatments under the conditional independence assumption. We show that under this assumption, matching with respect to the ratio of the scores allows...

We estimate a model of the joint participation and mobility along with the individuals' wage formation in France. Our model makes it possible to distinguish between unobserved person heterogeneity and state-dependence. We estimate the model using state of the art Bayesian methods employing a...

In this paper we estimate by matching techniques the effects of a French retraining program on the reemployment rate of laid-off workers. This program, called “Conventions de conversion”, was intended to improve reemployment prospects of displaced workers by proposing them retraining and job...

This paper investigates the effect of employment while in college on graduation, using data from the French Labour Force Surveys over the period 1992 to 2002. Using spatial variation in low-skill youth unemployment rates to circumvent the endogeneity of college employment decisions, we find a...

We present a model in which two of the most important features of the long-run growth process are reconciled: the massive changes in the structure of production and employment; and the Kaldor facts of economic growth. We assume that households expand their consumption along a hierarchy of needs...

This paper examines patent protection in an endogenous-growth model. Our aim is two-fold. First, we show how the patent policies discussed by the recent patent-design literature can influence R&D in the endogenous-growth framework, where the role of patents has been largely ignored. Second, we...
