International migration is a selective process that induces ambiguous effects on human capital and economic development in countries of origin. We establish the theoretical micro-foundations of the relationship between selective emigration and human capital accumulation in a multi-country...

Existing empirical literature provides converging evidence that selective emigration enhances human capital accumulation in the world's poorest countries. However, the within-country distribution of such brain gain effects has received limited attention. Focusing on Senegal, we provide evidence...

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 investigates the long-term implications of climate change on local, interregional, and international migration of workers. For nearly all of the world's countries, our micro-founded model jointly endogenizes the effects of changing temperature and sea level on income distribution and...

High-skilled workers are four times more likely to migrate than low-skilled workers. This skill bias in migration - often called brain drain - has been at the center of a heated debate about the welfare consequences of emigration from developing countries. In this paper, we provide a global...

This paper studies how return migration intentions affect immigrants' behavior. Using a unique French data set, we analyze the relationship between return plans and several immigrants' behavior in the host and origin countries addressing the potential endogeneity between return plans and...

Empirical evidence suggests that a large proportion of immigrants who initially intended to stay temporarily in the destination country end up staying permanently, which may lead to suboptimal integration. We study systematic causes of unexpected staying that originate in migrant misperceptions....

We analyze the externalities arising from a bilateral asylum policy - the list of safe origin countries - relying on a tractable model. Using self-collected monthly data, we estimate that including one origin country on the safe list of a given destination decreases asylum applications from that...

Is the brain drain a curse or a boon for developing countries? This paper reviews what is known to date about the magnitude of the brain drain from developing to developed countries, its determinants and the way it affects the well-being of those left behind. First, I present alternative...

This paper considers a three-overlapping-generations model of endogenous growth wherein human capital is the engine of growth. It first contrasts the laissez-faire and the optimal solutions. Three possible accumulation regimes are distinguished. Then it discusses a standard set of tax-transfer...
