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....

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...

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...

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...

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...

We investigate the welfare implications of two pre-crisis immigration waves (1991-2000 and 2001-2010) and of the post-crisis wave (2011-2015) for OECD native citizens. To do so, we develop a general equilibrium model that accounts for the main channels of transmission of immigration shocks - the...

Migrants are typically self-selected from the population of their home country. While a large literature has identified the causes of self-selection, we turn in this paper to the consequences. Using a combination of non-parametric econometrics and calibrated simulation, we quantify the impact of...

Immigration authorities have seldom collected data on the out-migration of the foreign-born. As a consequence, several indirect approaches have been proposed to measure and study out-migration. This paper adds to the literature by using official statistics that directly identify the...
