Collusion, agglomeration, and heterogeneity of firms

Abstract

Jehiel (1992) and Friedman and Thisse (1993) show that spatial agglomeration appears in a standard two-stage location price model if symmetric firms collude in prices. We introduce a cost difference between two firms. We show that agglomeration never appears in a collusive equilibrium even when the cost difference between firms is sufficiently small.
