Peer Effects in Exogenously Formed University Student Groups

Classroom Peer Effects and Student Achievement

Abstract: In this paper we analyze the impact of classroom peers’ ability on individual student achievement with a unique longitudinal data set covering all Florida public school students in grades 3–10 over a five-year period. Unlike many data sets used to study peer effects in education, ours identifies each member of a student’s classroom peer group in elementary, middle, and high school as ...

Peer-effects on Childhood Obesity: an Instrumental Variables Approach on Exogenously Assigned Peers

Homophily in Peer Groups

The focus of this paper is the endogenous formation of peer groups. In our model, agents choose peers before making contributions to public projects, and they differ in how much they value one project relative to another. Thus, the group’s preference composition affects the type of contributions made. We characterize stable groups and find that they must be sufficiently homogeneous. We also pro...

Peer Effects in Microenvironments: The Benefits of Homogeneous Classroom Groups

Many believe that classroom interactions play an important role in students’ academic achievement, but there is little evidence on peer effects within sub-classroom groups. We exploit random seat assignment in a Chinese middle school to estimate how the gender of neighboring students affects a student’s academic achievement. We find that being surrounded by five females rather than five males i...
