Social networks, be it on the internet or in real life, facilitate information flows. We model this by giving agents … incentives to link with others and receive information through those links. In many networks agents will value confirmation of … networks which are formed. We first study the existence of Nash equilibria and then characterize the set of strict Nash …

(1996). We prove that under heterogeneity in values or decay involving only two degrees of freedom, all networks can … supported as Nash. Moreover, we show that Nash networks may not always exist. In the absence of decay, neither result can be …

In this paper, we pursue the work of H. Haller and al. (2005, [10]) and examine the existence of equilibrium networks …, called Nash networks, in the noncooperative two-way flow model (Bala and Goyal, 2000, [1]) with partner heterogeneous agents …. We show through an example that Nash networks do not always exist in such a context. We then restrict the payoff function …
