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 …

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. Since … for reduced exposure to loss, and 2) uncertainty about the network structure makes it considerably more difficult to …
