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

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...

Recent theoretical studies suggest that migration prospects can raise the expected return to human capital and thus foster education investment at home or, in other words, induce a brain gain. In a recent paper we used the DOCQUIER and MARFOUK [2006] data set on emigration rates by education...

Recent data on international migration of skilled workers define skilled migrants by education level without distinguishing whether they acquired their education in the home or the host country. This article uses immigrants' age of entry as a proxy for where they acquired their education. Data...

In this paper, we develop a two-country stochastic simulation model based on the theory of optimum currency areas, which studies the desirability of a monetary union. Extending the general equilibrium model of Ricci (1995), we introduce the intertemporal dimension, which allows to deal more...

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...

This paper examines the relationship between international migration and source country fertility. The impact of international migration on source country fertility may have a number of causes, including a transfer of destination countries' fertility norms. We provide a rigorous test of the...

Immigrants in Rome or Paris are more visible to the public eye than the Italian or French engineers in Silicon Valley, especially when it comes to the debate on the effects of immigration on the employment and wages of natives in high-income countries. This paper argues that such public fears,...
