Taking algebra by eighth grade is considered an important milestone on the pathway to college readiness. We highlight a collaboration to investigate one district?s effort to increase middle school algebra course-taking. In 2010, the Wake County Public Schools began assigning middle school...

The relatively low degree completion rate of U.S. college students has prompted debate over the extent to which the problem is attributable to the students or to their choice of colleges.  Estimating the impact of initial college choice is confounded by the non-random nature of college...

We study an intensive math instruction policy that assigned low-skilled 9th graders to an algebra course that doubled instructional time, altered peer composition and emphasized problem solving skills. A regression discontinuity design shows substantial positive impacts of double-dose algebra on...

We analyze a Massachusetts merit aid program that gives high-scoring students tuition waivers at in-state public colleges with lower graduation rates than available alternative colleges. A regression discontinuity design comparing students just above and below the eligibility threshold finds...

Low income high school graduates are less likely to enroll in four-year colleges than their more advantaged peers. When they do enroll, they are more likely to choose colleges with low graduation rates and higher costs, increasing their risk of leaving college without a degree and with...

We explore the phenomenon of coauthorship by economists who share a surname. Prior research has included at most three economist coauthors who share a surname. Ours is the first paper to have four economist coauthors who share a surname, as well as the first where such coauthors are unrelated...

Billions of dollars are spent each year on early diagnosis and intervention programs for autism. However, there is little reliable evidence about the effectiveness of these programs. Few studies that evaluate early interventions for autism use random assignment or quasi-experimental designs, and...

Parental socioeconomic status (SES) may affect a child?s educational outcomes through a number of pathways, one of which is the child?s health. This essay asks two questions: What evidence exists about the effect of parental SES on child health? And, what evidence exists about the effect of...

Low college enrollment rates among low-income students may stem from a combination of credit constraints, low academic skill, and low-quality schools. Recent Massachusetts data allow the ?rst use of school district ?xed effects in the analysis of credit constraints, leading to four ?ndings....
