In this paper, we investigate the impact of attending school on body weight and obesity. We use school starting age cutoff dates to compare weight outcomes for similar age children with different years of school exposure. As is the case with academic outcomes, school exposure is related to...

Obesity has been one of the fastest growing health concerns among children, particularly among disadvantaged children. For children overall, obesity rates have tripled from 5% in the early 1970s to about 15% by the early 2000s. For disadvantaged children, obesity rates are closer to 20%. In this...

This paper investigates how accountability pressures under No Child Left Behind (NCLB) may affect children's rate of overweight. Schools facing increased pressures to produce academic outcomes may reallocate their efforts in ways that have unintended consequences for children's health. For...

We estimate the effects of having more mature peers using data from an experiment where children of the same age were randomly assigned to different kindergarten classrooms. Exploiting this experimental variation in conjunction with variation in expected kindergarten entry age to account for...

President Obama's "Preschool for All" initiative calls for dramatic increases in the number of 4 year olds enrolled in public preschool programs and in the quality of these programs nationwide. The proposed program shares many characteristics with the universal preschools that have been offered...

This paper investigates whether children are more or less likely to be overweight if their mothers work. The prevalence of both overweight children and working mothers has risen dramatically over the past few decades, although these parallel trends may be coincidental. The goal of this paper is...

The proportion of adolescents in the United States who are obese has nearly tripled over the last two decades. At the same time, schools, often citing financial pressures, have given students greater access to "junk" foods, using proceeds from the sales to fund school programs. We examine...

Is the Armed Forces Qualifying Test (AFQT) a measure of achievement or ability? The answer to this question is critical for drawing inferences from studies in which it is employed. In this paper, we test for a relationship between schooling and AFQT performance in the NLSY 79 by comparing...

It is widely documented that U.S. students score below their OECD counterparts on international achievement tests, but it is less commonly known that ultimately, U.S. native adults catch up. In this paper, we explore institutional explanations for differences in the evolution of literacy over...

In the 1960s and 1970s, many states introduced grants for school districts offering kindergarten programs. This paper exploits the staggered timing of these initiatives to estimate the long-term effects of a large public investment in universal early education. I find that white children aged...
