Starting in the 2013-2014 school year, I conducted a randomized field experiment in fifty traditional public elementary schools in Houston, Texas designed to test the potential productivity benefits of teacher specialization in schools. Treatment schools altered their schedules to have teachers...

Randomized field experiments designed to better understand the production of human capital have increased exponentially over the past several decades. This chapter summarizes what we have learned about various partial derivatives of the human capital production function, what important partial...

Motivated by the large differences in labor market outcomes across college majors, we survey the literature on the demand for and return to high school and post-secondary education by field of study. We combine elements from several papers to provide a dynamic model of education and occupation...

A longstanding question in the economics of the family is the relationship between sibship size and subsequent human capital formation and economic welfare. If there is a "quantity-quality trade-off," then policies that discourage large families should lead to increased human capital, higher...

More than a century has passed since the abrupt exodus of 1.2 million Greek Orthodox from Anatolia and their resettlement in Greece, a transformative event for the country's social and demographic landscape. Today, more than one in three Greeks reports a refugee background. While its historical...

This paper synthesizes what economists have learned about human capital since Becker (1962) into four stylized facts. First, human capital explains at least one-third of the variation in labor earnings within countries and at least half of the variation across countries. Second, human capital...

In the three decades before the pandemic, mean achievement of U.S. 8th graders in math rose by more than half a standard deviation on the National Assessment of Educational Progress (NAEP). Between 2019 and 2022, U.S. students had forfeited 40 percent of that rise. To anticipate the consequences...

Studies of small-scale "model" early-childhood programs show that high-quality preschool can have transformative effects on human capital and economic outcomes. Evidence on the Head Start program is more mixed. Inputs and practices vary widely across Head Start centers, however, and little is...

Using a regression discontinuity design generated by school-entry cutoffs and school records from an anonymous district in Florida, we identify externalities in human capital production function arising from sibling spillovers. We find positive spillover effects from an older to a younger child...

This paper studies the human capital responses to a large shock in the returns to education for undocumented youth. We obtain variation in the benefits of schooling from the enactment of the Deferred Action for Childhood Arrivals (DACA) policy in 2012, which provides work authorization and...
