We use recent immigration data from 195 countries and propose an index of population diversity based on people's birthplaces. This new index is then decomposed into a size (share of foreign born) and a variety (diversity of immigrants) component and is available for 1990 and 2000 disaggregated...

We use 130 years of data on historical migrations to the United States to show a causal effect of the ancestry composition of US counties on foreign direct investment (FDI) sent and received by local firms. To isolate the causal effect of ancestry on FDI, we build a simple reduced-form model of...

We establish an inverse relationship between family ties and political participation, such that the more individuals rely on the family as a provider of services, insurance, transfer of resources, the lower is one's civic engagment and political participation. We also show that strong family...

If individuals become aware of their stereotypes, do they change their behavior? We study this question in the context of teachers' bias in grading immigrants and native children in middle schools. Teachers give lower grades to immigrant students compared to natives who have the same performance...

We examine the relationship between immigration and attitudes toward redistribution using a newly assembled data set of immigrant stocks for 140 regions of 16 Western European countries. Exploiting within-country variations in the share of immigrants at the regional level, we find that native...

We show a causal impact of immigration on innovation and growth in US counties. To identify the causal impact of immigration, we use 130 years of detailed data on migrations from foreign countries to US counties to isolate quasi-random variation in the ancestry composition of US counties;...

We design and conduct large-scale surveys and experiments in six countries to investigate how natives perceive immigrants and how these perceptions influence their preferences for redistribution. We find strikingly large misperceptions about the number and characteristics of immigrants: in all...

This paper provides a simple conceptual framework that captures how different perceptions, attitudes, and biases about immigrants or minorities can shape preferences for redistribution. Through the lens of this framework, we review the empirical literature on the effects of racial diversity and...
