Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in an another one) affect the size and human-capital structure of current migration flows. Our...

The role of migrants' networks in promoting cross border investments has been stressed in the literature, possibly making migration and FDI complements rather than substitutes in the long run. In this paper, we estimate the magnitude of such business network externalities in dynamic empirical...
