We study within-family spillovers in college enrollment to show college-going behavior is transmissible between peers. Because siblings' test scores are weakly correlated, we exploit college-specific admissions thresholds that directly affect older but not younger siblings' college options....

Does access to four-year colleges affect degree completion for students who would otherwise attend two-year colleges? Admission to Georgia's four-year public sector requires minimum SAT scores. Regression discontinuity estimates show that access to this sector increases four-year college...

We demonstrate that heat inhibits learning and that school air-conditioning may mitigate this effect. Student fixed effects models using 10 million PSAT-retakers show hotter school days in years before the test reduce scores, with extreme heat being particularly damaging. Weekend and summer...

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...

Mapping continuous raw scores from millions of Advanced Placement examinations onto the 1 to 5 integer scoring scale, we apply a regression discontinuity design to understand how students' choice of college major is impacted by receiving a higher integer score despite similar exam performance to...

We implement a regression discontinuity design using the continuous raw Advanced Placement (AP) exam scores, which are mapped into the observed 1-5 integer scores, for over 4.5 million students. Earning higher AP integer scores positively impacts college completion and subsequent exam taking....

Only half of SAT-takers retake the exam, with even lower retake rates among low income and underrepresented minority (URM) students. We exploit discontinuous jumps in retake probabilities at multiples of 100, driven by left-digit bias, to estimate retaking's causal effects. Retaking...

We investigate the efficacy of text messaging campaigns to remind students about and support them with key steps in the college search, application, selection and transition process. First, in collaboration with the College Board and uAspire, both national non-profit organizations, we...

The Federal government has spent billions of dollars to support turnarounds of low-achieving schools, yet most evidence on the impact of such turnarounds comes from high-profile, exceptional settings and not from examples driven by state policy decisions at scale. In this paper, we study the...

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...
