We study learning and influence in a setting where agents communicate according to an arbitrary social network and … general structural conditions on the social network that are sufficient for convergence to truth. In addition, we show how …

We analyze delinquent networks of adolescents in the United States. We develop a dynamic network formation model … criminal activities, they can be key players because they have a crucial position in the network in terms of betweenness …

This paper studies whether conformism behavior affects individual outcomes in crime. We present a social network model … then bring the model to the data by using a very detailed dataset of adolescent friendship networks. A novel social network …

Suppose that individual payoffs depend on the network connecting them. Consider the following simultaneous move game of … network formation: players announce independently the links they wish to form, and links are formed only under mutual consent …. We provide necessary and sufficient conditions on the network link marginal payoffs such that the set of pairwise stable …

The paper presents a model of network formation where every connected couple gives a contribution to the aggregate … connected graph), which happens for high k, and there is no decay, the diameter of such a network never exceeds 8 (i.e. there …

This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The … experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by allowing … private information. In all treatments, the (efficient) equilibrium network has a “star” structure. With homogeneous agents …
