Does a high regional concentration of immigrants of the same ethnicity affect immigrant children's acquisition of host-country language skills and educational attainment? We exploit the exogenous placement of guest workers from five ethnicities across German regions during the 1960s and 1970s in...

Immigrants in many countries have lower employment rates and lower earnings than natives. We study whether a more liberal access to citizenship improves the economic integration of immigrants. Our analysis relies on two major immigration reforms in Germany, a country with a weak record of...

I show how the influences of unskilled immigration, differential fertility between immigrants and the local indigenous population, and incentives for investment in human capital combine to predict the decline of the West. In particular, indigenous low-skilled workers lose from unskilled...

This paper is the first to estimate a causal effect of immigrant students' reading performance on their math performance. To overcome endogeneity issues due to unobserved ability, we apply an IV approach exploiting variation in age-at-arrival and the linguistic distance between origin and...

After the collapse of the Soviet Union, more than 3 million people with German ancestors immigrated to Germany under a special law granting immediate citizenship. Exploiting the exogenous allocation of ethnic German immigrants by German authorities across regions upon arrival, we find that...

This paper studies the effect of emigration on gender norms in countries of migrants' origin. We use an instrumental variable strategy that allows us to estimate a causal effect of emigration on gender inequality. Our findings suggest that emigration to countries with low (high) levels of gender...
