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 study the long-run career mobility of young immigrants, mostly refugees, from Vietnam who moved to the United States during 1989-1995. This third and final migration wave of young Vietnamese immigrants was sparked by unexpected events that culminated in the Amerasian Homecoming Act....

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...

Immigrant distribution--the geographic dispersion of immigrants in the destination country--was a major issue in the United States in the late Age of Mass Migration. Policy debates were influenced by the widely held view that the new immigrants were generally less geographically mobile within...

We combine full-count Census data (1850-1940) with Census/ACS samples (1950-2020) to provide the first nationally representative long-run series (1850-2020) of incarceration rates for immigrants and the US-born. As a group, immigrants had higher incarceration rates than US-born white men before...

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...

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...

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....

Using longitudinal data on the universe of workers in Denmark during the period 1991-2008 we track the labor market outcomes of low skilled natives in response to an exogenous inflow of low skilled immigrants. We innovate on previous identification strategies by considering immigrants...
