This paper tackles the issue of self-selection in social interactions models. I develop a theory of sorting and behavior, when the latter is subject to social influences, extending the model developed by Brock and Durlauf (2001a, 2003) to allow for equilibrium group formation. Individuals choose...

The paper seeks to contribute to the social interactions literature by exploiting data on individuals’ self-selection into neighborhoods. We study a model in which households search for the best location in the presence of neighborhood effects in the formation of children’s human capital and...

In this paper we compare “micro” and “macro” labor supply elasticities in a MaCurdy-type equation. Using PSID data, we obtain the micro elasticity from standard panel techniques, and the macro elasticity from the time series generated by aggregating individuals every year. This procedure...

Empirical research has shown that social interactions affect the use of public benefits, thus providing evidence in favor of the idea of “welfare cultures.” In this paper we take the next crucial step by separately identifying the role of social stigma and information sharing in welfare...

This paper is a critical introduction to the new wave of economic literature on the effect of social interactions on individual behavior and aggregate economic outcomes. I refer to this research program, also known as new social economics, as the socioeconomic analysis of behavior, to...

We investigate the role of individual interdependencies in tax evasion, arising from congestion on the auditing resources available to local tax authorities. Identification exploits a novel method based on comparison of the variance of individual behavior — concealed income in this case — at...
