In this paper, we estimate the extent of ability peer effects in the classroom and explore the underlying mechanisms through which these peer effects operate. We identify as low ability students those who are enrolled at least one year behind their birth cohort (quot;repeatersquot;). We show...

We take cohorts of entering freshmen at the United States Air Force Academy and assign half to peer groups with the goal of maximizing the academic performance of the lowest ability students. Our assignment algorithm uses peer effects estimates from the observational data. We find a negative and...

In this paper, we study ability peer effects in secondary schools in England and identify which segments of the peer ability distribution drive the impact of peer quality on students‟ achievements. To do so, we use census data for four cohorts of pupils taking their age-14 national tests, and...

In this paper we investigate whether peers' behavior influences the choice of college major, thus contributing to the mismatch of skills in the labor market. Using a newly constructed dataset, we are able to identify the endogenous effect of peers on such decisions through a novel identification...

This paper examines the impact of youth friendship links on student's own academic performance (grade point average) using the Add Health. We estimate a reduced form, high dimensional fixed effects model of within cohort or grade friendship links, and use this model to predict each student's...

In this paper we analyze whether the gender composition of classmates in high school affects the choice of college-major by shifting it towards those majors preferred by the prevalent gender in the class. We use a novel dataset of 30,000 Italian students graduated from high school between 1985...

We motivate future neighborhood research through a simple model that considers youth educational outcomes as a function of neighborhood context, neighborhood exposure, individual vulnerability to neighborhood effects, and non-neighborhood educational inputs -- with a focus on effect...

Students starting at a two-year college are much less likely to graduate with a college degree than similar students who start at a four-year college but the sources of this attainment gap are largely unexplained. In this paper we simultaneously investigate the attainment consequences of sector...

Uncovering the effects of school racial composition on achievement is difficult, because racial mixing in the schools is not an accident but instead represents a complex mixture of government and family choices. While the goals of the integration of schools legally inspired by Brown v. Board of...
