Abstract

Heterogeneity in Nash networks can arise due to differences in the following four variables: (i) the value of information held by agents, (ii) the rate at which information decays or loses its value as it traverses the network, (iii) the prob- ability with which a links transmits information, and (iv) the cost of forming a link. In this paper we examine Nash networks, efficient networks and the existence of equilibrium networks under different heterogeneity conditions for the two-way flow model of networks.
