Abstract
This paper uses information from the National Longitudinal Survey of Youth 1979 (NLSY79) and supplementary data sources to examine how cognitive performance, measured at approximately the end of secondary schooling, is related to the labour market outcomes of 20 through 50 year olds. The analysis reveals five main findings. First, cognitive performance is positively associated with future labour market outcomes at all ages. Second, the returns to cognitive skill increase with age. Third, the effect on total incomes reflects a combination of positive impacts of cognitive performance for both hourly wages and annual work hours. Fourth, the returns to cognitive skill are greater for women than men and for blacks and Hispanics than for non-Hispanic whites, with differential effects on work hours being more important than corresponding changes in hourly wages. Fifth, the average gains in lifetime incomes predicted to result from greater levels of cognitive performance are only slightly above those reported in prior studies but the effects are heterogeneous, with larger relative and absolute increases, in most models, for non-whites or Hispanics than for non-Hispanic whites, and higher relative but not absolute returns for women than men.
