-players involved, there is the question of stability. We introduce and characterize a notion of marginal equilibrium, where all nodes … about node-players' information and is necessary for Nash equilibrium and for pairwise stability. Second, efficient networks … in absolute terms are characterized. Efficiency and stability are shown to be incompatible, but partial subsidizing is …
