This paper investigates three hypotheses to account for the observed shifts in U.S. relative wages of less educated compared to more educated workers between 1967 and 1992: increased import competition, changes in the relative supplies of labor of different education levels and changes in...

Chay, Guryan and Mazumder (2009) found substantial racial convergence in AFQT and NAEP scores across cohorts born in the 1960's and early 1970's that was concentrated among blacks in the South. We demonstrated a close tracking between variation in the test score convergence across states and...

Empirical studies of the relationship between school inputs and test scores typically do not account for the fact that households will respond to changes in school inputs. We present a dynamic household optimization model relating test scores to school and household inputs, and test its...

We consider the effect of legal access to alcohol on student achievement. We first estimate the effect using an RD design but argue that this approach is not well suited to the research question in our setting. Our preferred approach instead exploits the longitudinal nature of the data,...

Using data from the National Longitudinal Study of Adolescent Health, this study examines the impact of high school cohort composition on the educational and labor market outcomes of individuals during their early 20s and again during their late 20s and early 30s. We find that the positive...

A growing economics literature establishes a causal link between in utero shocks and health and human capital in adulthood. Most studies rely on extreme negative shocks such as famine and pandemics. We are the first to examine the impact of a positive and policy-driven change in economic...

Using data from a group incentive program that provides cash bonuses to teachers whose students perform well on standardized tests, we estimate the impact of incentive strength on student achievement. These awards are based on the performances of students within a grade, school and subject,...

We propose the rise of crack cocaine markets as an explanation for the end to the convergence in black-white educational outcomes beginning in the mid-1980s. After constructing a measure to date the arrival of crack markets in cities and states, we show large increases in murder and...

Using a sample of sibling pairs from the PSID-CDS, we examine the effects of sibling health status on early educational outcomes. We find that sibling developmental disability and externalizing behavior ar associated with reductions in math and language achievement Estimated spillovers for...
