We study the relationship between ethnicity, occupational choice, and entrepreneurship. Immigrant groups in the United States cluster in specific business sectors. For example, the concentration of Korean self-employment in dry cleaners is 34 times greater than other immigrant groups, and...

We use de-identified data from Facebook to study the social integration of Syrian migrants in Germany, a country that received a large influx of refugees during the Syrian Civil War. We construct measures of migrants’ social integration based on Syrians’ friendship links to Germans, their...

Recent theoretical work shows that precautionary savings increase in response to an increase in first-order risk. In addition, it is known that the welfare state, being an insurance or consumption-smoothing mechanism, reduces the negative welfare effect of future income uncertainty. We build a...

Gender differences in labor force participation are exceptionally small in Nordic countries. We investigate how couples emigrating from Denmark self-select and sort into different destinations and whether couples pursue the dual-earner model, in which both partners work, when abroad. Female...

Do policies and institutions that promote women's economic empowerment have a long-term impact on intimate partner violence? We address this question by exploiting a natural experiment of history in Cameroon. From the end of WWI until 1961, the western territories of today's Cameroon were...

We trace the development of human capital in today's Senegal, Gambia, and Western Mali between 1770 and 1900. European trade, slavery and early colonialism were linked to human capital formation, but this connection appears to have been heterogeneous. The contact with the Atlantic slave trade...

We examine colonial-era primary education as a determinant of modern-day attainment and gender disparities in education. We construct a novel dataset from the French Protectorate in Morocco, combining archival data on colonial school locations in 1931 and 1954 with the most recent Demographic...

We examine friendships and study partnerships among university students over several years. At the aggregate level, connections increase over time, but homophily on gender and ethnicity is relatively constant across time, university residences, and different network layers. At the individual...

Does higher office always lead to more favoritism? We argue that firms may lose their benefit from a connected politicians ascent to higher office, if it entails stricter scrutiny that may reduce favoritism. Around close Congress elections, we find RDD-based evidence of this adverse effect that...

A vast and growing quantitative literature considers how social networks shape political mobilization but the degree to which turnout decisions are strategic remains ambiguous. Unlike previous studies, we establish personal links between voters and candidates and exploit discontinuous incentives...
