We present an oligopoly model where a certain fraction of consumers engage in costly non-sequential search to discover … prices. There are three distinct price dispersed equilibria characterized by low, moderate and high search intensity … equilibrium consumers' search intensity, and(ii) to the status quo number of firms.For instance, when consumers search with low …

In this paper we analyse a model of oligopolistic competition in which consumers search without priors. Consumers do … not have prior beliefs about the distribution of prices charged by rms and thus try to use a robust search procedure: they … consumers stop searching with a probability strictly between zero and one. We show that for any distribution of search costs …
