Separate identification of the price and quantity of human capital has important implications for understanding key issues in economics. Price and quantity series are derived for four education levels. The price series are highly correlated and they exhibit a strong secular trend. Three...

It is often assumed that early life circumstances, in particular before age two, are important for later human capital development. Using experimental variation in the timing of benefits from a conditional cash transfer program, we test the hypothesis that intervention starting in utero and...

By allowing for an extensive margin in the standard quantity-quality model, we generate new insights into fertility transitions. We test the model on Southern black women aected by a large-scale school construction program. Consistent with our model, women facing improved schooling opportunities...

A model of human capital investment and activity choice is used to explain facts describing gender differentials in the levels and returns to human capital investments and occupational choice. These include the higher return to and level of schooling, the small effect of healthiness on wages,...

Human capital theory predicts that life expectancy will impact human capital attainment. We estimate this relationship using variation in life expectancy driven by Huntington disease, an inherited neurological disorder. We compare investments for individuals who have ex-ante identical risks of...

We examine characteristics of the 400 wealthiest individuals in the United States over the past three decades as tabulated by Forbes Magazine, and analyze which theories of increasing inequality are most consistent with these data. The people of the Forbes 400 in recent years did not grow up as...

Teacher contracts that condition pay and retention on demonstrated performance can improve selection into and out of teaching. I study alternative contracts in a simulated teacher labor market that incorporates dynamic self-selection and Bayesian learning. Bonus policies create only modest...

We identify a key role of factor supply, driven by demographic changes, in shaping several empirical regularities that are a focus of active research in macro and labor economics. In particular, demographic changes alone can account for the large movements of the return to experience over the...
