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 … throughout the entire network and uncover a general pattern of decreasing interdependence. …

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 …

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 …
