Social theories posit that peers affect students' academic self-concept (ASC). Most prominently, Big-Fish-Little-Pond, invidious comparison, and relative deprivation theories predict that exposure to academically stronger peers decreases students' ASC, and exposure to academically weaker peers...

High school track choice determines college access in many countries. We hypothesize that some qualified students avoid the college-bound track simply because they overestimate admission requirements. To test this hypothesis, we designed a randomized field experiment that communicated the...

This study examines the gendered effects of early and sustained exposure to high-performing peers on female educational trajectories. Exploiting random allocation to classrooms within middle schools, we measure the effect of male and female high performers on girls' high school placement...

This article relies on a large-scale field experiment in Mexico to measure the effects of two ability-grouping models (tracking and heterogeneous/bimodal groups) on student learning outcomes during middle school. Both strategies yielded an average learning gain of 0.08 of a standard deviation....

Obtaining consistent estimates of spillovers in an educational context is hampered by at least two issues: selection into peer groups and peer effects emanating from unobservable characteristics. We develop an algorithm for estimating spillovers using panel data that addresses both of these...

Other-regarding preferences are important for establishing and maintaining cooperative outcomes. In this paper, we study how formation of other-regarding preferences during childhood is affected by parental background. Our subjects, aged 4-12 years, are classified into other-regarding types...

This paper evaluates how sharing a kindergarten classroom with low-achieving repeaters affects the long-term educational performance of regular first-time kindergarten students. Exploiting random assignment of teachers and students to classes in Project STAR, I document three sets of causal...

The influx of immigrants has shifted the ethnic composition of public schools in many states including North Carolina. Recent evidence from North Carolina suggests that increases in Limited English students' concentration have led to a slight decline in performance solely for students at the top...

We examine the effect of peer achievement on students' own achievement and teacher performance in primary schools in disadvantaged neighborhoods using data from a well-executed randomized experiment in seven states. Contrary to the existing literature, we find that the average classroom peer...

There is a perception among native born parents in the U.S. that the increasing number of immigrant students in schools creates negative peer effects on their children. In North Carolina there has been a significant increase in immigrants especially those with limited English language skills and...
