In this paper we develop a model in which students choose their university coursework based on both investment and consumption incentives. We show that these education decisions are socially inefficient. This result is driven by the fact that students do not consider an externality in the...

Obesity rates continue to climb in the US. Recent work explores social factors that may contribute to these trends, including social norms. Most work in this area focuses on adults and older youth, missing key early years. This paper explores obesity peer effects in New York City schools for...

Despite extensive literature on peer effects, the role of peers on personality skill development remains poorly understood. We fill this gap by investigating the effects of having disadvantaged primary school peers, generated by random classroom assignment and parental migration for employment....

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...

We investigate externalities in higher education enrollment over the course of development in a two-sector model. Each sector works with only one type of labor, skilled or unskilled, and individuals are differentiated according to their cost of acquiring human capital. Both sectors exhibit...

Despite extensive literature on peer effects, the role of peers on personality skill development remains poorly understood. We fill this gap by investigating the effects of having disadvantaged primary school peers, generated by random classroom assignment and parental migration for employment....

This study builds on the findings of Carrell and Hoekstra (2010, 2018) by exploring the peer effects of domestic violence exposure over the academic attainment of secondary school students in Peru. However, we also study these peer effects over a novel set of outcomes: internalizing behaviors...

In the research on peer effects, unweighted mean classroom performance is the predominant measure used in the estimation of education production functions. In this paper, based on the sociological concept of homophily, I introduce social network matrices that correspond to a weighting scheme for...

Despite extensive literature on peer effects, the role of peers on personality skill development remains poorly understood. We fill this gap by investigating the effects of having disadvantaged primary school peers, generated by random classroom assignment and parental migration for employment....

We exploit the randomized evaluation of a remedying education intervention that improved the reading skills of low-performing third grade students in Colombia, to study whether providing educational support to low-achieving students affects the academic performance of their higher-achieving...
