into account the potential externalities networks produce. 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 …

The paper analyzes a dynamic model of rational strategic learning in a network. It complements existing literature by … network. We show that the delay in information transmission caused by incomplete network structures may induce players to … increase own experimentation efforts. As a consequence a complete network can fail to be optimal even if there are no costs for …

emerge at equilibrium. We define the notion of coalitional network to represent a network and a coalition structure, where … the network specifies the nature of the relationship each individual has with his coalition members and with individuals … outside his coalition. To predict the coalitional networks that are going to emerge at equilibrium we propose the concept of …

We develop a network model whose links are governed by banks' optmizing decisions and by an endogenous tâtonnement … evolution of the network configuration under various prudential policy regimes, to measure banks' contribution to systemic risk …

network of agents. In our model, agents are identically informed a priori and observe network neighbors’ actions as well as … observed payoffs and imitate observed actions. Our results also allow us to interpret critical mass and network brokerage …

This paper analyses a simultaneous game of network formation and information acquisition where the benefit structure is … such that the benefit that an agent derives from the network she is located in depends on the maximum information that … someone in her neighbourhood, including herself, acquires. It turns out that in equilibrium star network emerges as the unique …

This paper studies fictitious play in networks of noncooperative two-person games. We show that continuous … convergence is 1/T, regardless of the size of the network. In contrast, arbitrary n-person zero-sum games with bilinear payoff … functions do not possess the continuous-time fictitious-play property. As extensions, we consider networks in which each …

Agents in a network want to learn the true state of the world from their own signals and their neighbors' reports …. Agents know only their local networks, consisting of their neighbors and the links among them. Every agent is Bayesian with … the (possibly misspecified) prior belief that her local network is the entire network. We present a tractable learning …

Individuals have a strong tendency to coordinate with all their neighbors on social and economics networks … multiplex network who deal with coordination issues using social learning and payoff-driven dynamics. Agents form their …
