In a social network, agents have their own reference group that may influence their behavior. In turn, the agents …' attributes and their behavior affect the formation and the structure of the social network. We survey the econometric literature …

. We present a new model of network formation that allows the linking process to depend on individuals types and study the … impact of such a bias on the network structure. Our main results fall into three categories: (i) we compare the distributions …

-in-means model where each individual has his own specific reference group. Interactions are thus structured through a social network … exogenous effects are generally identified under network interaction, although identification may fail for some particular … structures. Monte Carlo simulations provide an analysis of the effects of some crucial characteristics of a network (i …

network is defined as an equilibrium outcome of a game in cover function form. Our results bridge the two strands of …

well as for the identity of the key player. We study the possibility of testing endogeneity in network formation. We … analysis suggests that greater care should be taken in grounding econometric network models to sound and credible theoretical …

equilibrium behaviors are linked through the Laplacian matrix of the equilibrium network. I show that conformism has positive … social value and that social welfare can be bounded by network centrality and connectivity measures. I apply the model using … (i.e. endogenous peer effect for a fixed network structure) range from 7.5% to 45%, depending on the number of peers that …
