Student Abilities During the Expansion of U.S. Education, 1950-2000

Hendricks, Lutz and Schoellman, Todd (2009): Student Abilities During the Expansion of U.S. Education, 1950-2000.

Abstract

Since 1950, U.S. educational attainment has increased substantially. While the median student in 1950 dropped out of high school, the median student today attends some college. In an environment with ability heterogeneity and positive sorting between ability and school tenure, the expansion of education implies a decrease in the average ability of students conditional on school attainment. Using a calibrated model of school choice under ability heterogeneity, we investigate the quantitative impact of rising attainment on ability and measured wages. Our findings suggest that the decline in average ability depressed wages conditional on schooling by 31-58 percentage points. We also find that the entire rise in the college wage premium since 1950 can be attributed to the rising mean ability of college graduates relative to high school graduates.
