High-Skilled Immigration, STEM Employment, and Nonroutine-Biased Technical Change

We study the role of foreign-born workers in the growth of employment in STEM occupations since 1980. Given the importance of employment in these fields for research and innovation, we consider their role in a model featuring endogenous non-routine-biased technical change. We use this model to quantify the impact of high-skilled immigration, and the increasing tendency of such immigrants to work in innovation, on the pace of non-routine-biased technical change, the polarization of employment opportunities, and the evolution of wage inequality since 1980.
