Abstract

This paper unifies two significant but somewhat contradictory ideas. First, search costs potentially influence market price equilibria significantly; in many equilibria consumers do not search despite above-competitive prices. Second, cartels must guard against individual members offering lower prices, thereby creating incentives for consumers to search. We develop a simple framework, and then an example, in which whether search takes place depends upon the magnitude of search costs. Three potential equilibria result, dependent upon model parameters. These include a tacit cartel agreement exhibiting price variance and volatility. A policy conclusion is that such market characteristics do not always guarantee non-cartelisation.
