Despite great focus on and public investment in STEM education, little causal evidence connects quantitative coursework to students' economic outcomes. I show that state changes in minimum high school math requirements substantially increase Black students' completed math coursework and their...

Do nudge interventions that have generated positive impacts at a local level maintain efficacy when scaled state or nationwide? What specific mechanisms explain the positive impacts of promising smaller-scale nudges? We investigate, through two randomized controlled trials, the impact of a...

Low college enrollment rates among low income students may stem from credit constraints, low academic skill, low quality schools, or some combination of these. Recent Massachusetts data allow the first use of school district fixed effects in the analysis of credit constraints, leading to four...

Success or failure in freshman math has long been thought to have a strong impact on subsequent high school outcomes. We study an intensive math instruction policy in which students scoring below average on an 8th grade exam were assigned in 9th grade to an algebra course that doubled...

To better prepare students for college-level math and the demands of the labor market, school systems have tried to increase the rigor of students’ math coursework. The failure of universal “Algebra for All” models has led recently to more targeted approaches. We study one such approach in...

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...

Most states now fund merit-based financial aid programs, the effects of which depend on how strongly students react to changes in college costs. I estimate such reactions using quasiexperimental aspects of a recent Massachusetts merit scholarship program intended to attract talented students to...

Data on millions of SAT-takers show only half retake the exam, with even lower retake rates among low income and underrepresented minority students. Scoring below multiples of 100 increases retaking, implying some students have round number target scores. Regression discontinuity evidence finds...

We provide the first evidence that cumulative heat exposure inhibits cognitive skill development and that school air conditioning can mitigate this effect. Student fixed effects models using 10 million PSAT-takers show that hotter school days in the year prior to the test reduce learning, with...

We provide the first estimated economic impacts of students’ access to an entire sector of public higher education in the U.S. Approximately half of Georgia high school graduates who enroll in college do so in the state’s public four-year sector, which requires minimum SAT scores for...
