A great deal of urban policy depends on the possibility of creating stable, economically and racially mixed neighborhoods. Many social interaction models - including the seminal Schelling (1971) model -- have the feature that the only stable equilibria are fully segregated. These models suggest...

We examine peer effects in early education by estimating value added models with school fixed effects that control extensively for individual, family, peer, and teacher characteristics to account for the endogeneity of peer group formation. We find statistically significant and robust spillover...

We specify and implement a test for the presence and importance of labor market network based on residential proximity in determining the establishments at which people work. Using matched employer-employee data at the establishment level, we measure the importance of these network effects for...

Are individuals more likely to smoke when they are surrounded by smokers? In this paper, we examine the evidence for peer effects in smoking. We address the endogeneity of peers by looking at the impact of workplace smoking bans on spousal and peer group smoking. Using these bans as an...

This paper uses the random assignment of playing partners in professional golf tournaments to test for peer effects in the workplace. We find no evidence that the ability of playing partners affects the performance of professional golfers, contrary to recent evidence on peer effects in the...

This paper develops a model of social interactions with endogenous association. People are assumed to invest in relationships to maximize their utility. Even in a linear-in-means model, when associations are endogenous, the effect of macro-group composition on behavior is non-linear and varies...

This paper develops a framework to understand the role of interpersonal interactions in the labor market including task assignment and wages. Effective interpersonal interactions involve caring, to establish cooperation, and at the same time directness, to communicate in an unambiguous way. The...

Peer effects have figured prominently in debates on school vouchers, desegregation, ability tracking and anti-poverty programs. Compelling evidence of their existence remains scarce for plaguing endogeneity issues such as selection bias and the reflection problem. This paper firmly establishes a...

In this paper we investigate how direct-to-consumer (DTC) advertising of pharmaceutical products in affected by regulations of the Food and Drug Administration and by market conditions. We focus on a relatively under-studied segment of the pharmaceutical market -- the market for smoking...

Departures from self-centred, consumption-oriented decision making are increasingly common in economic theory and are well motivated by a wide range of behavioural data from experiments, surveys, and econometric inference. A number of studies have shown large negative externalities in individual...
