Essays on Labor Market Policies Evaluation.

Summary In the first two chapters, we estimate the impact of two labor market policies in the French context: * anonymous applications: information, such as name, gender, age, nationality and address, is erased from resumes sent to employers (first chapter). Anonymous applications limit differential treatments based on gender and counter homophily. * Unemployment Insurance generosity: job losers receive benefits to prevent revenue loss and to subsidize job search (second chapter). We show that an increase of 8 months in potential benefit duration does not affect match quality, while it slows down unemployment exits to jobs. We devote special attention to identify causal impacts and thus rely on experimental or quasi experimental evidence to perform our empirical evaluation exercises. Namely, we compare treated and control groups which are ex ante statistically identical. However, we discuss two potential caveats of microeconometric evaluations in the context of Job Search Assistance evaluation, one "practical" in the third chapter and one "theoretical" in the fourth chapter: * ex post comparability of control and treated groups when sample attrition can be different among experimental groups (third chapter). * uncontrolled contamination between control and treated group through market interaction (fourth chapter).
