This paper examines effects of the U.S. Immigration Act of 1990 on STEM (science, technology, engineering, and mathematics) degree completion and labor market outcomes for native-born Americans. The Act increased the in-flow and stock of foreign STEM workers in the U.S., both by increasing green...

How many "American jobs" have U.S.-born workers lost due to immigration and offshoring? Or, alternatively, is it possible that immigration and offshoring, by promoting cost-savings and enhanced efficiency in firms, have spurred the creation of jobs for U.S. natives? We consider a multi-sector...

Characteristics of skilled immigrant workers – age, educational attainment, and occupational skills – changed after the U.S. immigration policy shock of 2004 when the maximum number of new skilled immigrant visas was reduced to 90,000. We observe a higher (lower) probability of hiring...

This paper uses several decades of US time-diary surveys to assess the impact of low-skilled immigration, through lower prices for commercial child care, on parental time investments. Using an instrumental variables approach that accounts for the endogenous location of immigrants, we find that...

This paper examines the effects of foreign- and native-born STEM graduates and non-STEM graduates on patent intensity in U.S. metropolitan areas. I find that both native and foreign-born STEM graduates significantly increase metropolitan area patent intensity, but college graduates in non-STEM...
