Abstract
Earnings growth has been systematically decreasing from one cohort to the next, starting with the cohort that was 25-year-old in 1940. This cohort's labor earnings were multiplied by a factor of 4 between the ages of 25 and 55. For the 1980 cohort the same calculation yields a factor of 2.2. Why are recent cohorts facing flatter earnings profiles? Our theory combines two elements: (1) the incentives to accumulate human capital over one's work life are decreasing in the initial stock of human capital; (2) recent cohorts are more educated and do start their work lives with more human capital. We build and calibrate a parsimonious model of schooling and human capital accumulation on the job to fit the earnings of the 1940 cohort at different ages. Our model accounts for more than 60% of the decline in the growth rate of earnings between the 1940 and the 1980 cohorts as the result of a single exogenous factor: increasing aggregate productivity.
