Abstract

We provide the existence of pairwise stable weighted networks under assumptions similar to Nash theorem. In particular, contrarily to the case of unweighted networks, the existence of closed improving cycles does not prevent the existence of Pairwise stable weighted networks. Then, we extend our existence result, allowing payoffs to depend on some game-theoretic strategies. Many applications are given.
