This paper estimates peer effects in a university context where students are randomly assigned to sections. While students benefit from better peers on average, low-achieving students are harmed by high-achieving peers. Analyzing students' course evaluations suggests that peer effects are driven...

A substantial share of university instruction happens in tutorial sessions - small group instruction given parallel to lectures. In this paper, we study whether instructors with a higher academic rank teach tutorials more effectively in a setting where students are randomly assigned to tutorial...

This paper provides evidence on ability peer effects in university education. Identification comes from the random assignment of students to sections. We find that students on average benefit from better-ability peers. Low-ability students, however, are harmed by high-ability peers. We introduce...

Teachers often deliver the same lesson multiple times in one day. In contrast to year-to-year teaching experience, it is unclear how this teaching repetition affects student outcomes. We examine the effects of teaching repetition in a setting where students are randomly assigned to a university...

This paper studies how a student's ordinal achievement rank affects performance and specialization choices in university. We exploit data from a setting where students are randomly assigned to teaching sections and find that students with a higher rank in their section achieve higher grades,...
