We study self-selection in centralized school choice, a strategy that takes place when students submit preferences before knowing their priorities at schools. A student self-selects if she decides not to apply to some schools despite being desirable. We give a theoretical explanation for this...

This paper develops a model that allows for heterogenous contemporaneous peer effects among different types of agents who are endogenously selected into different peer groups. Using our framework, we characterize the reduced-form coefficient in the peer effect literature and show that it is a...

Educational attitudes are an important component of adolescent development linked to long-term educational success and as a component of noncognitive skills. This study focuses on peer and parent roles in shaping adolescent attitude development. First, I explore the relationship between an...

Peer effects in education production functions are predominantly employed as the mean classroom performance. Based on sociological theory and using spatial regression techniques, I introduce social network matrices that correspond to a weighting scheme for peers within the class. In a spatial...

We examine college students’ interaction within classrooms and estimate peer effects on their academic performance. We exploit a unique seating rule at a university in South Korea, known as the fixed-seat system. We propose a novel identification strategy based on students’ repeated...

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...

This paper considers the problem of making inferences about the effects of a program on multiple outcomes when the assignment of treatment status is imperfectly randomized. By imperfect randomization we mean that treatment status is reassigned after an initial randomization on the basis of...

Using daily lunch transaction data from NYC public schools, I determine which students frequently stand next to one another in the lunch line. I use this `revealed' friendship network to estimate academic peer effects in elementary school classrooms, improving on previous work by defining not...
