May 2015Foreign and Native Skilled Workers: What Can We Learn from H-1B Lotteries?
with Giovanni Peri, Chad Sparber: w21175
In April of 2007 and 2008, the U.S. randomly allocated 65,000 H-1B temporary work permits to foreign-born skilled workers. About 88,000 requests for computer-related H-1B permits were declined in each of those two years. This paper exploits random H-1B variation across U.S. cities to analyze how these supply shocks affected labor market outcomes for computer-related workers. We find that negative H-1B supply shocks are robustly associated with declines in foreign-born computer-related employment, while native-born computer employment either falls or remains constant. Most of the correlation between H-1B supply shocks and foreign employment is due to rationing that varies with a city's initial dependence upon H-1B workers. Variation in random, lottery-driven, unexpected shocks is too small ...
May 2014Foreign STEM Workers and Native Wages and Employment in U.S. Cities
with Giovanni Peri, Chad Sparber: w20093
Scientists, Technology professionals, Engineers, and Mathematicians (STEM workers) are fundamental inputs in scientific innovation and technological adoption, the main drivers of productivity growth in the U.S. In this paper we identify the effect of STEM worker growth on the wages and employment of college and non-college educated native workers in 219 U.S. cities from 1990 to 2010. In order to identify a supply-driven and heterogeneous increase in STEM workers across U.S. cities, we use the distribution of foreign-born STEM workers in 1980 and exploit the introduction and variation of the H-1B visa program granting entry to foreign-born college educated (mainly STEM) workers. We find that H-1B-driven increases in STEM workers in a city were associated with significant increases in wages ...
