In a 1-year randomized controlled trial involving thousands of university students, we provide real-time private feedback on relative performance in a semester-long online assignment. Within this setup, our experimental design cleanly identifies the behavioral response to rank incentives (i.e.,...

Gender peer effects are potentially important for optimally organizing schools and neighborhoods. In this paper, we examine how the gender of classmates and neighbors affects a variety of high school outcomes and choice of university major. Given that students are assigned to schools based on...

Why are females compared to males both more likely to have strong STEM-related performance and less likely to study STEM later on? We exploit random assignment of students to classrooms in Greece to identify the impact of comparative advantage in STEM relative to non-STEM subjects on STEM...

Would you prefer a tighter or a prolonged exam schedule? Would you prefer to take Math before Reading or the other way around? We exploit variation in end-of-course exam schedules across years and grades to identify distinct effects of the number of days between exams, the number of days since...

To reduce sugar intake in children, California regulates the provision of sugar-sweetened beverages and juice by child care facilities. The regulation may reduce children's consumption of sugary beverages in the short run and weaken their preferences for sugary drinks in the long run. Whether...

In several countries, students who fail end-of-high-school high-stakes exams are faced with the choice of retaking them or forgoing postsecondary education. We explore exogenous variation generated by a 2006 policy that imposed a performance threshold for admission into postsecondary education...

How much does your neighbor impact your test scores and career? In this paper, we examine how an observable characteristic of same-age neighbors their gender affects a variety of high school and university outcomes. We exploit randomness in the gender composition of local cohorts at birth from...

How can individuals respond to their ordinal ranking when they are not aware of it? We present evidence on the effects and mechanisms of achievement rank effects in middle schools when ranks are salient to students and their parents. For identification, we rely on the random assignment of...
