Econometrics Workshop: Vincent Boucher

Equilibrium Homophily in Networks

Abstract:  I look at the equilibrium effects of homophily in networks formation games with positive network externalities. I show that very weak preferences for network effects (such as preferences for being part of a clique) may result in very high levels of homophily at equilibrium. I present an empirical procedure that allows to evaluate the role of network effects on the observed level of homophily in the data. I apply my method to the formation of friendship network in the USA. I show that network effects are small, and have a negligible contribution to observed racial homophily in friendship networks.
