In our opinion, the trend in the BMI values of US children has not been estimated accurately. We use five models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 born 1941-2006 on the basis of all NHES and NHANES data sets. We also use some...

Families originally living in public housing were assigned housing vouchers by lottery, encouraging moves to neighborhoods with lower poverty rates. Although we had hypothesized that reading and math test scores would be higher among children in families offered vouchers (with larger effects...

Proposed "free college" policies vary widely in design. The simplest approach sets tuition to zero for everyone. More targeted approaches limit free tuition to those who successfully demonstrate need through an application process. We experimentally test the effects of these two models on the...

Low-income students, even those with strong academic credentials, are unlikely to attend a highly selective college. With a field experiment, we test an intervention to increase enrollment of low-income students at the highly selective University of Michigan. We contact students (as well as...

This paper reports the results of a pilot study, using a randomized controlled trial to provide college counseling to high-achieving students from relatively poor families. We followed 107 high school seniors through the college admissions process in 2006-2007; we selected 52 of these students at...

We review the experimental and quasi-experimental research evidence on the causal relationship between college costs and educational attainment, with a particular focus on low-income populations. The weight of the evidence indicates that reducing college costs can increase college entry and...

We study the effects of a change in financial aid policy introduced by a Northeastern university in 1998. Prior to that time, the university's financial aid packages for low-income students consisted of grants, loans, and campus jobs. After the change, the entire loan portion of the package for...

This paper estimates the sensitivity of students' college application decisions to a small change in the cost of sending standardized test scores to colleges. Using confidential ACT micro data, I find that when the ACT increased from three to four the number of free score reports that ACT-takers...

In response to low take-up, many public schools have experimented with moving breakfast from the cafeteria to the classroom. We examine whether such a program increases performance as measured by standardized test scores, grades and attendance rates. We exploit quasi-random timing of program...
