Essais sur les dynamiques du marché du travail

Abstract : This thesis aims at understanding labor market dynamics. In order to shed light on the mechanisms at the origin of labor market stocks, e.g. the unemployment rate, this thesis studies flows of workers. Indeed, changes in stocks hide a perpetual movement of worker flows between labor market states. When some individuals are finding a job, some others are losing their, while others are withdrawing from participation. To take into account all these alternatives, this thesis proposes applied studies, based on survey data, but also theoretical analyses, based on modern macroeconomic models. The four essays of this thesis suggest that non-participation and return to job are dominant in explaining French unemployment variations. It is also shown that, in terms of worker flows, paths are multiples and depend on individual own characteristics: “unskilled” workers accumulate difficulties on the labor market; women have lower chances of participating when their family size increases. At a macroeconomic level, this thesis shows that worker flows responses to aggregate shocks differ according to their origin. Moreover, the economic environment has a direct impact on worker flows. Times of uncertainty, characterized by a high level of unpredictability, change the behavior of economic agents. As search activities have a lower probability to be successful, fewer individuals move from non-participation to participation.
