Both the anomalies of education history, and its less surprising contrasts, fit broad patterns that can be revealed and partially explained using low-tech methods. Over most of human history, contrasts in the output of education were driven mainly by contrasts in the supply of tax support for...

Harlem Children's Zone (HCZ), which combines community investments with reform minded charter schools, is one of the most ambitious social experiments to alleviate poverty of our time. We provide the first empirical test of the causal impact of HCZ on educational outcomes, with an eye toward...

We examine effects of state-level job losses on student achievement. Losses to 1% of the working-age population decrease eighth-grade math scores by .076 standard deviations, with consistently negative but less precise effects on eighth-grade reading and on fourth-grade math and reading. Effects...

Short-cycle higher education programs (SCPs) can play a central role in skill development and higher education expansion, yet their quality varies greatly within and among countries. In this paper we explore the relationship between programs' practices and inputs (quality determinants) and...

We provide evidence that the robust association between cognitive skills and economic growth reflects a causal effect of cognitive skills and supports the economic benefits of effective school policy. We develop a new common metric that allows tracking student achievement across countries, over...

Decentralization of decision-making is among the most intriguing recent school reforms, in part because countries went in opposite directions over the past decade and because prior evidence is inconclusive. We suggest that autonomy may be conducive to student achievement in well-developed...

Empirical studies in the economics of education, the measurement of skill gaps across demographic groups, and the impacts of interventions on skill formation rely on psychometrically validated test scores that record the proportion of items correctly answered. Test scores are sometimes taken as...

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...

This paper develops a model of crime in which human capital increases the opportunity cost of crime from foregone work and expected costs associated with incarceration. Older, more intelligent, and more educated adults should commit fewer street (unskilled) crimes. White collar crimes decline...

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...
