We estimate the causal impact of school and classroom gender composition on achievement. We take advantage of the random assignment of Korean middle school students to single-sex schools, co-educational (coed) schools with single-sex classes, and coed schools with mixed-gender classes. Male...

This paper reviews the recent literature on measuring and boosting cognitive and noncognitive skills. The literature establishes that achievement tests do not adequately capture character skills|personality traits, goals, motivations, and preferences that are valued in the labor market, in...

We consider the classic problem of estimating group treatment effects when individuals sort based on observed and unobserved characteristics that affect the outcome. Using a standard choice model, we show that controlling for group averages of observed individual characteristics potentially...

Several school districts use assignment systems in which students have a strategic incentive to misrepresent their preferences. Indeed, we find evidence suggesting that reported preferences in Cambridge, MA respond to these incentives. Such strategizing can complicate the analysis of...

We make use of a new data resource, merged birth and school records for all children born in Florida from 1992 to 2002, to study the effects of birth weight on cognitive development from kindergarten through schooling. Using twin fixed effects models, we find that the effects of birth weight on...

Since Coleman (1966), many have questioned whether school spending affects student outcomes. The school finance reforms that began in the early 1970s and accelerated in the 1980s caused some of the most dramatic changes in the structure of K–12 education spending in US history. To study the...

Existing estimates of the labor-market returns to human capital give a distorted picture of the role of skills across different economies. International comparisons of earnings analyses rely almost exclusively on school attainment measures of human capital, and evidence incorporating direct...

Using data from the NLSY97 we analyze the impact of education on health behaviors, measured by smoking and heavy drinking. Controlling for health knowledge does not influence the impact of education on health behaviors, supporting the productive efficiency hypothesis. Although cognition, as...

There has been a resurgence in research that investigates the efficacy of early investments as a means of reducing gaps in academic performance. However, the strongest evidence for these effects comes from experimental evaluations of small, highly enriched programs. We add to this literature by...

We find large effects on the earnings of participants from a randomized intervention that gave psychosocial stimulation to stunted Jamaican toddlers living in poverty. The intervention consisted of one-hour weekly visits from community Jamaican health workers over a 2-year period that taught...
