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...

Summary 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...

In this paper, we analyze the distribution of the brain drain in the LAC region (Latin America and the Caribbean), Asia and Africa. We rely on an original data set on international migration by educational attainment for 1990 and 2000. Our analysis reveals that the brain drain is strong in...

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 use a multilevel approach to characterize the relationship between weather shocks and (internal and international) migration intentions. We combine individual survey data on migration intentions with measures of localized weather shocks for Western African countries over 2008-2016. A...

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 sheds light on the global migration patterns of the past 40 years, and produces migration projections for the 21st century, for two skill groups, and for all relevant pairs of countries. To do this, we build a simple model of the world economy, and we parameterize it to match the...

Discussions of high-skilled mobility typically evoke migration patterns from poorer to wealthier countries, which ignore movements to and between developing countries. This paper presents, for the first time, a global overview of human capital mobility through bilateral migration stocks by...
