Essais d'évaluation de politique publique dans les champs de l'éducation, de la santé et des politiques d'emploi

Abstract : This thesis provides 5 essays on public policy evaluation. We first consider a job-search counseling program targeted at individuals that have been on welfare for at least two years. We evaluate the impact of this policy on job access and its cost-effectiveness, using a random allocation of welfare recipients to the program. Its effects on employment are, in general, far too small to ensure that the program is cost-effective for the public budget. Then we test whether parental leave duration has a causal impact on later wages, with two modeling strategies : the first one uses a difference in difference approach, whereas the other imposes more structure and specifies a selection equation. Our results suggest that parental leave duration has a negative causal impact on wages. The last two chapters of this thesis are devoted to returns to education on health, with the use of two different instrumental variables. The first instrument induced some students to give up school earlier than they wished, whereas the other instrument forced some students to exceed their otherwise optimal level of education. We find significant returns only in the first case, when the set of compliers is composed of motivated students. Hence this suggests that differences in motivation may be a source of heterogeneity in returns to education on health.
