We address the problem of a planner looking for the efficient network when agents play a network game with local … complementarities and links are costly. We show that for general network cost functions, efficient networks belong to the class of … Nested-Split Graphs. Next, we refine our results and find that, depending on the specification of the network cost function …

throughout the entire network and uncover a general pattern of decreasing interdependence. …We study network games under strategic complementarities. Agents are embedded in a fixed network. They choose a … positive, continuous action and interact with their network neighbors. Interactions are positive and actions are bounded from …

network structure and we examine equilibrium selection. Specifically, actions are either strategic substitutes or strategic … complements, and participants have either complete or incomplete information about the structure of a random network.
