Description:
We present a model of directed communication network with endogenous link strength. Agents are endowed with a fixed amount of resource which they can distribute over links. They obtain indirect benefit by the path maximizing the product of link strength. In this environment, the wheel architecture is shown to be not only the unique efficient architecture but also the unique Nash architecture
