Using detailed data on friendship networks within neighborhoods, we investigate the importance of social interactions in one’s own residential neighborhood in the demand for housing quality. We find evidence consistent with the presence of peer effects, especially for households living in...

In this paper we relate a particular form of social interactions, i.e. peer group influences, to the structure of the network from which they originate. Using an extremely detailed dataset on friendship relationships between students from U.S. school, we find evidence suggesting that the...

This paper studies the identification and estimation of treatment response with heterogeneous spillovers in a network model. We generalize the standard linear-in-means model to allow for multiple groups with between and within-group interactions. We provide a set of identification conditions of...

We consider a production function model that transforms worker inputs into outputs through peer effect networks. The distinguishing features of this production model are that the network is formal and observable through worker scheduling, and selection into the network is done by a manager. We...

We analyze peer effects in sleeping behavior using a representative sample of U.S. teenagers from the National Longitudinal Survey of Adolescent Health. The sampling design of the survey causes the conventional 2SLS estimator to be inconsistent. We extend the NLS estimator in Wang and Lee...
