We examine the formation of networks among a set of players whose payoffs depend on the structure of the network. We … links. We characterize the networks that are supported under these variations and show how each of the above aspects is …

Our main … measures, and generates a finite, disjoint collection of nonempty subsets of networks and coalitions, each constituting a basin …

Given the preferences of players and the rules governing network formation, what networks are likely to emerge and … persist? And how do individuals and coalitions evaluate possible consequences of their actions in forming networks? To address … these questions we introduce a model of network formation whose primitives consist of a feasible set of networks, player …
