This paper reviews the existing literature on the impact of migrants networks on the patterns of international migration. It covers the theoretical channels at stake in the global effect of the networks. It identifies the key issues, namely the impact on size, selection and concentration of the...

This paper examines the relationship between the brain drain and country size, as well as the extent of small states’ overall loss of human capital. We find that small states are the main losers because they i) lose a larger proportion of their skilled labor force and ii) exhibit stronger...

Summary In this paper, we revisit the impact of skilled emigration on human capital accumulation using new panel data covering 147 countries during the period 1975-2000. We derive testable predictions from a stylized theoretical model and test them in dynamic regression models. Our empirical...

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms, both of which are affected by the presence of a diaspora abroad. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in another one) affect the size...
