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 …

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 …

This paper develops a formal model of exchange network stability that combines expected value theory (Friedkin 1995 …) with the economic literature on network dynamics. We identify stable networks up to size 8 for varying costs and …
