This paper reviews four decades of economics research on the brain drain, with a focus on recent contributions and on development issues. We first assess the magnitude, intensity and determinants of the brain drain, showing that brain drain (or high-skill) migration is becoming the dominant...

We investigate the relationship between the presence of migrant inventors and the dynamics of innovation in the migrants’ receiving countries. We find that countries are 25 to 50 percent more likely to gain advantage in patenting in certain technologies given a twofold increase in the number...

During the early 1990s Germany received over half a million Yugoslavian refugees fleeing war. By 2000, many of these refugees, who were under temporary protection, had been repatriated. We exploit this historical episode to provide causal evidence on the role that migrants play explaining export...

Do migrants shape the dynamic comparative advantage of their sending and receiving countries? To answer this question we study the drivers of knowledge diffusion by looking at the dynamics of the export basket of countries, with particular focus on migration. The fact that knowledge diffusion...

France experienced the demographic transition before richer and more educated countries. This paper offers a novel explanation for this puzzle that emphasizes the diffusion of culture and information through internal migration. It tests how migration affected fertility by building a decennial...

We examine both theoretically and empirically how migration affects cultural change in home and host countries. Our theoretical model integrates various compositional and cultural transmission mechanisms of migration-based cultural change for which it delivers distinctive testable predictions on...

How does immigration affect export performance? To answer this question we propose a unified empirical framework allowing to disentangle various mechanisms such as the role of networks in reducing bilateral transaction costs as well as productivity shifts arising from migration-induced knowledge...

This paper quantitatively investigates the short- and long-run effects of liberalizing global migration on the world distribution of income. We develop and parametrize a dynamic model of the world economy with endogenous migration, fertility and education decisions. We identify bilateral...
