August 1999 - Adherents of the natural trading partner hypothesis argue that preferential trade agreements are more likely to improve welfare if participating countries already trade disproportionately with each other. Opponents argue the opposite. Neither side is right. The hypothesis holds up...

We explore the complementarities between high-skill emigration and poverty in developing countries. We build a model endogenizing human-capital accumulation, high-skill migration and productivity. Two countries sharing the same characteristics may end up either in a "low poverty/low brain drain"...

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 (Beine, Docquier and Rapoport, Economic Journal, 2008) we used the Docquier and...

This chapter focuses on the effects of skilled migration on developing countries. We first present new evidence on the magnitude of the "brain drain" at the international level. Using a stylized model of education investment in a context of migration, we then survey the theoretical and empirical...

We develop a model to study the effects of migration and remittances on inequality in the origin communities. While wealth inequality is shown to be monotonically reduced along the time-span, the short- and the long-run impacts on income inequality may be of opposite signs, suggesting that the...

Recent data on international skilled migration define skilled migrants according to education level independently of whether education has been acquired in the home or in the host country. In this paper we use immigrants' age of entry as a proxy for where education has been acquired. Data on age...

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...

Although movements of capital, goods and services are growing in importance, workers movements are impeded by restrictive policies in rich countries. Such regulations carry substantial economic costs for developing countries, and prevent global inequality from declining. Even if rich countries...

This chapter reviews the recent theoretical and empirical economic literature on migrants' remittances. It is divided between a microeconomic section on the determinants of remittances and a macroeconomic section on their growth effects. At the micro level we first present in a fully harmonized...
