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. Our results suggest that student interactions outside the classroom - especially...

This paper examines how peer quality within distinct college majors affects graduation rates and major persistence. To mitigate the selection problem, we control for school-specific fixed effects, as well as very flexible application-admissions pattern fixed effects. Non-science peer quality...

In this paper we investigate whether peers' behavior influences the choice of college major. Using a unique dataset of students at Bocconi University and exploiting the organization of teaching at this institution, we are able to identify the endogenous effect of peers on such decision through a...

This chapter summarizes the recent literature on peer effects in student outcomes at the elementary, secondary, and post-secondary levels. Linear-in-means models find modest sized and statistically significant peer effects in test scores. But the linear-in-means model masks considerable...

Can students' rank in the ability distribution of their class impact their academic achievement? We aim to answer this question using a discontinuity generated by a rule for the distribution of students between classes at a prestigious Brazilian university. The rule means that in almost 30 per...

Any system of primary and secondary schools involves explicit or implicit mechanisms that ration not only financial but also nonfinancial inputs into education production. This chapter focuses primarily on such mechanisms as they relate to the sorting of parents and children into schools and...

Students face four decision margins: (a) How many years to spend in school, (b) What to study, (c) How much effort to devote to learning per year and (d) Whether to disrupt or assist the learning of classmates. The thousands of studies that have applied human capital theory to the first two...

We survey the theoretical and empirical literature on peer effects in education. Theoretical models of peer effects are first summarized. Models of educational provision regimes in which peer effects play a central role are then discussed. Next we discuss the identification issues in estimating...

Using longitudinal data from the Italian National Institute for the Evaluation of the Education System (INVALSI), this paper investigates whether the ability of classmates affects the educational attainment of immigrant students. We focus not only on the average quality of peers in the class,...
