The United States has admitted more than 3 million refugees since 1980 through official refugee resettlement programs. Scholars attribute the success of refugee groups to governmental programs on assimilation and integration. Before 1948, however, refugees arrived without formal selection...

Historical accounts suggest that Jewish émigrés from Nazi Germany revolutionized U.S. science. To analyze the émigrés' effects on chemical innovation in the U.S. we compare changes in patenting by U.S. inventors in research fields of émigrés with fields of other German chemists. Patenting...

We exploit differences in the mortality rates faced by European colonialists to estimate the effect of institutions on economic performance. Our argument is that Europeans adopted very different colonization policies in different colonies, with different associated institutions. The choice of...

In the late 19th and early 20th centuries, the North American agricultural frontier moved for the first time into semi-arid regions where farming was vulnerable to drought. Farmers who migrated to the region had to adapt their crops, techniques, and farm sizes to better fit the environment. But...

The number of refugees worldwide is now 12 million, up from 3 million in the early 1970s. And the number seeking asylum in the developed world increased tenfold, from about 50,000 per annum to half a million over the same period. Governments and international agencies have grappled with the twin...

Children of refugees are among the most economically disadvantaged youth in several European countries. They are more likely to drop out of school and to commit crime. We show that a reform in Denmark in 1999, that expanded language training for adult refugees and improved their economic...

This paper studies the effects of threat on convergence to local culture and economic assimilation of refugees, exploiting plausibly exogenous variation in their allocation across German regions between 2013 and 2016. We combine novel survey data on cultural preferences and economic outcomes of...

The continuing inflow of hundreds of thousands of refugees into many European countries has ignited much political controversy and raised questions that require a fuller understanding of the determinants and consequences of refugee supply shocks. This paper revisits four historical refugee...

This paper investigates how the size of co-ethnic networks at the time of arrival affect the economic success of immigrants in Germany. Applying panel analysis with a large set of fixed effects and controls, we isolate the association between initial network size and long-run immigrant outcomes....

We construct longitudinal data from the U.S. Census records to study migration patterns of those affected by the Dust Bowl of the 1930s. Our focus is on the famous "Okie" migration of the Southern Great Plains. We find that migration rates were much higher in the Dust Bowl than elsewhere in the...
