- As indicated in the attached image, U.S. earnings for high- and low-skill workers as measured by educational attainment began diverging in the 1980s. The remaining questions in this problem set use the model for the labor market developed in class to walk through potential explanations for this trend. 1. Assume that there are just two types of workers, low- and high-skill. As a result, there are two labor markets: supply and demand for low-skill workers and supply and demand for high-skill workers. Using two carefully drawn labor-market figures, show that an increase in the demand for high skill workers can explain an increase in the relative wage of high-skill workers. 2.
