endogenous structure of collaboration is represented by a weighted network. The agents are forward-looking and capable of … solution. I find stable networks in which agents collaborate only within exclusive groups. Both an absence of intergroup …

I propose a simple model of signed network formation, where agents make friends to extract payoffs from weaker enemies … equilibria cannot be Pareto ranked. This paper offers a game-theoretic foundation for a large body of work on signed networks …

We study the formation of networks in environments where agents derive benefits from other agents directly linked to … networks with undirected links (e.g. epidemics, underground resistance organizations, trade networks) where we find that stable … networks are comprised of completely connected disjoint subnetworks. Then, we consider networks with directed links and we find …

This paper studies a non-cooperative model of network formation. Built upon the two-way flow model of Bala and Goyal … number of his links. This assumption results in the fact that a large set of Nash networks are disconnected and consist of … components of different sizes, a feature that resembles that of real-world networks. Discussions on this insight are provided …

. In public goods games played on networks, such an agent will attempt to manipulate as many of his neighbors as possible …. We show the existence and payoff-uniqueness of optimal farsighted strategies in every network structure. In the long run … for every network if the starting state is unfavorable, and reaches it for every starting state if the farsighted player …

We introduce a model of strategic experimentation on social networks where forwardlooking agents learn from their own … own experimentation, so total information decreases with network density; we determine density thresholds below which … agents asymptotically learn the state. In contrast, agent welfare is single-peaked in network density, and achieves a second …

minority agents are in the social network, the more they assimilate to the majority culture. We also show that denser networks …) embedded in a network have to decide how much effort they exert in some activity (say education).
