College Attainment, Income Inequality, and Economic Security: A Simulation Exercise

Abstract

We conduct an empirical simulation exercise that gauges the plausible impact of increased rates of college attainment on a variety of measures of income inequality and economic insecurity. Using two different methodological approaches--a distributional approach and a causal parameter approach--we find that increased rates of BA and AA attainment would meaningfully increase economic security for lower income individuals and shrink gaps between the 90th percentile and lower percentiles. Increases in college attainment would not significantly reduce inequality at the very top of the distribution, as measured by the 99/90 earnings ratio.
