The role of migrant networks in the labour market outcomes of Senegalese men : how destination contexts matter

Research on the role of co-ethnic ties in immigrants’ labour market outcomes has reached mixed conclusions. Some argue they are a valuable resource, increasing immigrants’ labour force participation and wages; others find negative effects such as trapping workers in low-quality employment. Thus far very few quantitative studies have investigated systematically the circumstances under which migrant networks work. Taking advantage of unique data on Senegalese men in France, Italy and Spain, this paper shows that the receiving context shapes the role of pre-migration ties. In France, where the Senegalese community is well-established and socio-economically diverse, networks lead to better economic prospects. In contrast, pre-migration ties in Italy and Spain mostly lead to the perpetuation of ethnic niches developed by the Senegalese in small and precarious trade activities. The article emphasizes the benefits of adopting a comparative and diachronic approach and calls for future work on the factors shaping the role of networks
