The proportion of foreign-born people in rich countries has tripled since 1960, and the emigration of high-skilled people from poor countries has accelerated. Many countries intensify their efforts to attract and retain foreign students, which increases the risk of brain drain in the sending...

One of the most salient features of developing economies is the existence of a large informal sector. This paper uses quantitative theory to study the dynamic implications of informality on wage inequality, human capital accumulation, child labor and long-run growth. Our model can generate...

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...

Most of the recent literature on the effects of the brain drain on source countries consists of theoretical papers and cross-country empirical studies. In this paper we complement the literature through three case studies on very different regional and professional contexts: the African medical...

We investigate the relationship between remittances and migrants' education both theoretically and empirically, using original bilateral remittance data. At a theoretical level we lay out a model of remittances interacting migrants' human capital with two dimensions of immigration policy:...

Emigration first increases before decreasing with economic development. This bell-shaped relationship between emigration and development was first hypothesized by the theory of the mobility transition (Zelinsky, 1971). Although several mechanisms have been proposed to explain the upward segment...

This paper empirically investigates whether emigrants from MENA countries self-select on cultural traits such as religiosity and gender-egalitarian attitudes. To do so, we use Gallup World Poll data on individual opinions and beliefs, migration aspirations, short-run migration plans, and...

This paper analyzes the factors underlying the evolution of the worldwide distribution of skills and their implications for global inequality. We develop and parameterize a two-sector, two-class, world economy model that endogenizes education and mobility decisions, population growth, and income...

This paper revisits the question of how brain drain affects the optimal education policy of a developing economy. Our framework of analysis highlights the complementarity between public spending on education and students' efforts to acquire human capital in response to career opportunities at...

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...
