Technical Change, Heterogeneity in Skill Demand, and Employment Polarization

We explore how the rapid adoption of computer-related assets affects the recent polarization of employment in the U.S. labor market, which is inconsistent with the skill-biased technological change hypothesis.

Our empirical analyses confirm that the newly adopted computer-related capitals change the demands for three types of skilled workers heterogeneously, leading to a polarization in employment structure
