Network Effects in International Migration: Education versus Gender *

In this paper, we analyze the impact that networks have on the structure of international migration flows. In particular, we investigate whether diaspora externalities are different across education levels and gender. Using new data that include both dimensions, we analyze the respective impact that networks have on the proportion of each category of migrant. Therefore, in contrast to the preceding body of literature on the macro determinants of international migration, we can identify the factors that influence the selection in terms of skills and in terms of gender. We find that network effects vary by education level, but not by gender.
