Unlucky migrants: Scarring effect of recessions on the assimilation of the foreign born

This paper studies how aggregate labor market conditions affect the intra-generational assimilation of immigrants in the hosting country. Using data from the American Community Survey, we leverage variation in the national unemployment rates in the U.S. at the time of arrival of different cohorts of immigrants to identify short- and long-run effects of recessions on their careers. We document that immigrants who enter the U.S. when the labor market is slack face large and persistent earnings reductions: a 1 p.p. rise in the unemployment rate at the time of migration reduces annual earnings by 4.9 percent on impact and 0.7 percent after 12 years since migration, relative to the average U.S. native. Change in the employment composition across occupations with different skill contents is the key driver: were occupational attainment during periods of high unemployment unchanged for immigrants, assimilation in annual earnings would slow down on average by only 3 years, instead of 12. Slower assimilation costs between 1.7 and 2.4 percent of lifetime earnings to immigrants entering the U.S. labor market when unemployment is high.
