This paper develops a strategic network formation model where agents have heterogeneous knowledge of … the network: cognizant agents know the whole network, while ignorant ones are less knowledgeable.

Imperfect private monitoring in an infinitely repeated discounted Prisoner’s Dilemma played on a communication network …’s history throughout the network. The delay in receiving this information requires the players to be more patient to sustain the … same level of cooperation as in a complete network, although a Folk Theorem obtains when the players are patient enough …

We study from both a theoretical and an empirical perspective how a network of military alliances and enmities affects … the intensity of a conflict. The model combines elements from network theory and from the politico-economic theory of … characterization of the Nash equilibrium of the fighting game, and of how the network structure affects individual and total fighting …

A principal offers bilateral contracts to a set of agents organized in a network conveying synergies, in a context … optimal contracts as a function of agents' positions on the network. The analysis shows that contract enforceability is key to … contract with a single agent on the network. Last, we extend this setting to network entry. …

The Folk Theorem extends to this setup, although for a range of … produces a network result; namely, the level of cooperation in this setup depends on the network’s diameter, and not on its …

We consider agents playing a linear network game with strategic complementarities. We analyse the problem of a policy … maker who can change the structure of the network in order to increase the aggregate efforts of the individuals and/or the … sum of their utilities, given that the number of links of the network has to remain fixed. We identify some link …
