We study mergers in a market where N firms sell a homogeneous good and consumers search sequentially to discover prices. The main motivation for such an analysis is that mergers generally affect market prices and thereby, in a search environment, the search behavior of consumers. Endogenous...

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, respectively. We show that the effects of an increase in...

We modify the paper of Stahl (1989) [Stahl, D.O., 1989. Oligopolistic pricing with sequential consumer search. American Economic Review 79, 700–12] by relaxing the assumption that consumers obtain the first price quotation for free. When all price quotations are costly to obtain, the unique...

Despite the mixed empirical evidence, many economists still hold to the view that Internet will promote competition between firms, thereby lowering prices and increasing economic welfare. This paper presents a search model that provides a different view. We analyze the market for a homogeneous...

This paper examines the effect of price matching guarantees (PMGs) on market outcomes in a sequential search model. PMGs are simultaneously chosen with prices and some consumers (shoppers) know the firms’ decisions before buying, while others (non-shoppers) enter a shop before observing the...
