We compile large datasets from Norwegian and US historical censuses to study return migration during the Age of Mass Migration (1850-1913). Return migrants were somewhat negatively selected from the migrant pool: Norwegian immigrants who returned to Norway held slightly lower-paid occupations...

Using novel data on 50,000 Norwegian men, we study the effect of wealth on the probability of internal or international migration during the Age of Mass Migration (1850-1913), a time when the US maintained an open border to European immigrants. We do so by exploiting variation in parental wealth...

Using millions of father-son pairs spanning more than 100 years of US history, we find that children of immigrants from nearly every sending country have higher rates of upward mobility than children of the US-born. Immigrants' advantage is similar historically and today despite dramatic shifts...

Using two million census records, we document cultural assimilation during the Age of Mass Migration, a formative period in US history. Immigrants chose less foreign names for children as they spent more time in the US, eventually closing half of the gap with natives. Many immigrants also...

Asian Americans are the fastest-growing racial group in the US but we know little about how Asian immigration has affected cities, neighborhoods and schools. This paper studies white flight from Asian arrivals in high-socioeconomic-status Californian school districts from 2000-2016 using initial...

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...

Since the 1970s, computerized machine tools have been replacing semi-skilled manufacturing workers, contributing to factory automation. We build a novel measure of exposure to computer numerical control (CNC) based on initial variation in tool types across industries and differential shifts...
