Unobserved ability heterogeneity has long been postulated to play a key role in human capital development. Traditional strategies to estimate education production functions do not allow for varying role or development of unobserved ability as a child ages. Such restrictions are highly...

The hypothesized effects of educational attainment on adult civic engagement and attitudes provide some of the most important justifications for government intervention in the market for education. In this study, I present evidence on whether these externalities exist. I assess and implement two...

Recent research on the economics of human development deepens understanding of the origins of inequality and excellence. It draws on and contributes to personality psychology and the psychology of human development. Inequalities in family environments and investments in children are substantial....

We explore whether early childhood human-capital investments are complementary to those made later in life. Using the Panel Study of Income Dynamics, we compare the adult outcomes of cohorts who were differentially exposed to policy-induced changes in pre-school (Head Start) spending and...

We present the results of a novel early childhood intervention in which disadvantaged 3-4-year- old children were randomized to receive a new preschool and parent education program focused on cognitive and non-cognitive skills (CogX) or to a control group that did not receive preschool...

This paper evaluates the long-run effects of Head Start using large-scale, restricted 2000-2018 Census-ACS data linked to the SSA’s Numident file, which contains exact date and county of birth. Using the county rollout of Head Start between 1965 and 1980 and age-eligibility cutoffs for school...

A growing literature establishes that high quality early childhood interventions targeted toward disadvantaged children have substantial impacts on later life outcomes. Little is known about the mechanisms producing these impacts. This paper uses longitudinal data on cognitive and personality...
