We estimate spillovers from public funding for health research in the context of the NIH's Fogarty International Center's AIDS International Training and Research Program, which aims to strengthen scientific capacity in AIDS endemic countries by providing African researchers with training...

Why were the poorer countries of the European periphery latecomers to the Age of Mass Migration? We test the diffusion hypothesis, which argues that mass emigration was delayed because it was primarily governed by a gradual process of spatial diffusion of migration networks. We propose a model...

Seit dem Jahr 2017 wird im Mikrozensus erfasst, welche Motive im Ausland geborene Personen für ihren Zuzug hatten. Daraus lassen sich neue Erkenntnisse darüber gewinnen, in welchen Kontexten die Zuwanderung nach Deutschland erfolgt. So zeigt eine eigene Auswertung, dass im Jahr 2017 rund 1,06...

The effects of immigration are reasonably well understood in developed countries, but they are far more poorly understood in developing ones despite the importance of these countries as immigrant destinations. We address this shortcoming by studying the effects of immigration to Brazil during...

Argentina was the second largest destination country during the Age of Mass Migration, receiving nearly six million migrants. In this article, we first summarize recent findings characterizing migrants' long-term economic assimilation and their contributions to local economic development. The...

The number of individuals forcibly displaced by conflicts has been rising in the past few decades. However, we know little about the dynamics--magnitude, timing, and persistence--of conflict-induced migration in the short run. We use novel high-frequency data to estimate the dynamic migration...

Internal migration in the United States has declined substantially over the past several decades, which has important implications for individual welfare, macroeconomic adjustments, and other key outcomes. This paper studies the determinants of internal migration and how they have changed over...

This paper introduces the concept of "climate matching" as a driver of migration and establishes several new results. First, we show that climate strongly predicts the spatial distribution of immigrants in the US, both historically (1880) and more recently (2015), whereby movers select...

I study the internal migration of native-born white men in the United States using linked census data covering all possible 10- and 20-year periods 1850--1940. Inter-county migration rates were stable over time. Selection into migration on the basis of occupational status was also largely stable...
