This paper proposes three theoretical mechanisms through which polygyny may be related to social unrest. The mechanisms are related to different dimensions of grievance-inducing and, partly, greed-related inequality, which may occur in polygynous societies. These dimensions include (i)...

This paper proposes three theoretical mechanisms through which polygyny may be related to social unrest. The mechanisms are related to different dimensions of grievance-inducing and, partly, greed-related inequality, which may occur in polygynous societies. These dimensions include (i) economic,...

This paper looks at the effect of the relatedness of two countries, measured by their genetic distance, on educational migrant selection. We analyze bilateral country-level education-specific migration stocks from 85 sending countries to the 15 main destination countries in 2000 and show that...

This paper studies a two-region model in which unemployment, education decisions and interregional migration are endogenous. The poorer region exhibits both lower wages and higher unemployment rates, and migrants to the richer region are disproportionally skilled. The brain drain from the poor...

In this note, we present a novel channel for a brain gain. Students from a developing country study in a developed host country. A higher permanent migration probability of these students appears to be a brain drain for the developing country in the first place. However, it induces the host...

Does U.S. military aid make the United States safer? To answer this question, we collect data on 173 countries between 1968 and 2014. Exploiting quasi-random variation in the global patterns of U.S. military aid, our paper is the first to provide causal estimates of the effect of U.S. military...
