摘要:This paper addresses the existence of Nash equilibria in one-way flow or
directed network models in a number of different settings. In these models
players form costly links with other players and obtain resources from them
through the directed path connecting them. We find that heterogeneity in the
costs of establishing links play a crucial role in the existence of Nash
networks. We also provide conditions for the existence of Nash networks in
models where costs and values of links are heterogeneous.
