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 the productivity- and wage-returns to firm-provided training in a panel of French Firms. We find positive and significant returns to training on productivity. For instance, an increase in training intensity by 150 Euros per worker increases a firms labor productivity by 0.4 %....

The aim of this paper is to estimate moral hazard effects on health expenditures based on French data. Recent studies have underlined that selection on the market of insurance is partly due to unobservable characteristics and not only to observable ones (such as health condition). Methods using...

In this article, we study the impact of payroll tax subsidies for low-wage workers on various outcomes of the firms, including employment, in particular that of young and less skilled workers. We concentrate on the effects of the 1995 and 1996 tax cuts policies, which permit large decreases in...
