The first chapter examines the role of individuals’ culture of origin in explaining the gender gap in youth’s decision to delay moving out from the parental household. I show that in societies with traditional values about gender roles, young have more incentives than young women to live longer with their parents. When women from these cultures live in a more liberal society regarding gender roles, they move out faster from the parental household and also seek to find a husband from a different culture than their own. In the 2nd chapter, we show, based on a correspondence study that low-skilled youth are less likely to be called back by private sector employers when they are North-African rather than French. By contrast, the origin of the fictitious applicants does not impact their callback rate in the public sector, despite the similar negative discriminatory beliefs of recruiters in both sectors. Our model shows that the absence of discrimination at the invitation for an interview stage in the public sector is compatible, in this context, with stronger discrimination in hiring. The third chapter is also based on a correspondence study and investigates the effects of the labor market experience of high school dropouts four years after leaving school. Compared to those who have stayed unemployed since leaving school, the callback rate is not raised for those with employment experience, whether it is subsidized or non-subsidized, in the market or non-market sector, if there is no training accompanied by skill certification. Moreover, training accompanied by skill certification improves callback rates only when the local unemployment rate is low.
