It is more difficult for migrants than natives to find a job in their host country, so many of them have to accept, at least temporarily, a job that is below their level of qualification. This represents a waste of human capital for society and can undermine social cohesion. Relying on social relationships might help them to bypass some of the obstacles that prevent them from finding a job that matches their skillset. We focus on migrants who arrived in France before the age of 18 years, who were educated entirely or partially in France. We use the rich French Trajectories and Origins dataset for 2009 to study the impact of personal contacts on the quality of the current employment. We measure the job quality using an indicator based on the educational requirement for a given occupation. To address the endogeneity between our dependent variable (holding a suitable job or not) and the variable of interest (employment found through a personal contact or not), we use the variable “sibling(s) in France” as an instrument: this variable influences an individual’s probability of finding a job through contacts but does not influence directly the quality of the employment. Our results indicate that for these migrants, finding a job through personal contacts strongly and positively impacts the occupational status attained: it raises both women's and men’s probability of holding a suitable job by more than 0.40 points.
