On the Equilibrium Properties of Network Models with Heterogeneous Agents

No 27837, NBER Working Papers from National Bureau of Economic Research, Inc

Abstract: We consider a broad class of network models where a large number of heterogeneous agents simultaneously interact in many ways. We provide a new theorem that offers an iterative algorithm for calculating an equilibrium and sufficient and “globally necessary” conditions under which the equilibrium is unique. We illustrate that a wide variety of heterogeneous agent economies yield equilibrium representations amenable to our theorem's characterization.
