Separating Uncertainty from Heterogeneity in Life Cycle Earnings

Working Paper: NBER ID: w11024

Authors: Flavio Cunha; James J. Heckman; Salvador Navarro

Abstract: This paper develops and applies a method for decomposing cross section variability of earnings into components that are forecastable at the time students decide to go to college (heterogeneity) and components that are unforecastable. About 60% of variability in returns to schooling is forecastable. This has important implications for using measured variability to price risk and predict college attendance.
