Informal social interactions, behavior, and academic achievement
Abstract
We study the effects of informal social interactions on academic achievement and behavior using idiosyncratic variation in peer groups stemming from changes in bus routes across elementary, middle, and high school. In early grades, a one standard-deviation change in the value-added of same-grade bus peers corresponds to a 0.01 SD change in academic performance and a 0.03 SD change in behavior; by high school, these magnitudes grow to 0.04 SD and 0.06 SD. These findings suggest that student interactions outside the classroom—especially in adolescence—may be an important factor in the education production function.

PhD candidate in Education Policy & Program Evaluation
I am a Ph.D. candidate at the Harvard Graduate School of Education (HGSE) in its Education Policy and Program Evaluation concentration. My research centers on using causal inference research designs to measure the impacts of education programs and policies. I typically study topics at the intersection of education and economics, but also draw from the traditions of sociology and political science. My current projects focus on career and technical education, peer effects, school choice, and teacher labor markets.
