It is widely recognized that the shape of networks influences both individual and aggregate behavior. This raises the … question which types of networks are likely to arise. Our paper fits into the literature that addresses this question. The … paper continues on the work of Galeotti, Goyal and Kamphorst (2003). In their paper they investigate a model of network …

This paper studies network formation in settings where players are heterogeneous with respect to benefits as well as … the costs of forming links. Our results demonstrate that centrality, center-sponsorship and short network diameter are … robust features of equilibrium networks. We find that in a society with many groups, where it is cheaper to connect within …

Once social ties are in place, these externalities shape the … that the individual's incentives depend on the architecture of the network as well as on the position of the individual … within the network. In particular, when an efficient interaction requires players to mutually cooperate, efficient social …

A symmetric network consists of a set of positions and a set of bilateral links between these positions. Examples of … such networks are exchange networks, communication networks, disease transmission networks, control networks etc. For every … symmetric network we define a cooperative transferable utility game that measures the power of each coalition of positions in …
