La démocratisation de l'enseignement en France et ses répercussions en termes de taux de rendement sur le marché du travail.

This study focus on the impact of the schooling massification on the rate of return to schooling in France during the period 1983 to 2002. Moreover, it allows us to make a statement on the advancement of econometric methods that have been developed during the past fifty years. In this way, we explain why it is essential for us to introduce implicit and explicit costs, taxes on wages or the probability of unemployment, which differs according to schooling attainment. When we take into account these several elements, the rate of return of High School degree decreases until 1990. He is now negative around -3% contrary to the return to college who converge to 8%. The schooling democratization seems to lead to a depreciation of the High School degree. It gives birth to a new period compartmentalizing individuals who continue school in college or not in two distinct classes.
