A slowdown in the growth of the relative supply of skilled workers

Real Wage Inequality† By Enrico Moretti* While nominal wage differences between skilled and unskilled workers have increased since 1980, college graduates have experienced larger increases in cost of living because they have increasingly concentrated in cities with high cost of housing. Using a cityspecific CPI, I find that real wage differences between college and high school graduates have grown significantly less than nominal differences. Changes in the geographical location of different skill groups are to a significant degree driven by city-specific shifts in relative demand. I conclude that the increase in utility differences between skilled and unskilled workers since 1980 is smaller than previously thought based on nominal wage differences. (JEL J22, J23, J24, J31, R23, R31) One of the most important developments in the US labor market….

Nominal and Real Wage Differences

In this section, I estimate how much of the increase in nominal wage differences between college graduates and high school graduates is accounted for by differences in the cost of living. In particular, in Section IA, I show estimates of the college premium in nominal and real terms. In Section IB, I discuss whether my estimates are biased by the presence of unobserved worker characteristics or unobserved housing characteristics. In Section IC, I show estimates of the college premium in real terms
