African-Americans entered the post-Civil War era with extremely low levels of exposure to schooling. Relying primarily on micro-level census data, we describe racial differences in literacy rates, school attendance, years of educational attainment, age-in-grade distributions, spending per pupil,...

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...

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...

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 investigates the economic consequences of the 1882 Chinese Exclusion Act, which banned immigration from China to the United States. The Act reduced the number of Chinese workers of all skill levels residing in the U.S. It also reduced the labor supply and the quality of jobs held by...

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...

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 evaluates the U.S. Census Bureau's most recent data collection efforts to classify business entities that engage in an extreme form of production fragmentation called "factoryless" goods production. "Factoryless" goods-producing entities outsource physical transformation activities...

This paper: outlines an algorithm for concording U.S. ten-digit Harmonized System export and import codes over time; describes the concordances we construct for 1989 to 2004; and provides Stata code that can be used to construct similar concordances for arbitrary beginning and ending years from 1989...
