This paper develops a dynamic model of consumer search that, despite placing very little structure on the dynamic … problem faced by consumers, allows us to exploit intertemporal variation in within-period price and search cost distributions … to estimate the population distribution from which consumers' search costs are initially drawn. We show that static …

The search literature assumes that consumers know which firms sell products they are looking for, but are unaware of … the basic fact that they sell the product. In this way, advertising lowers the expected search cost. We show that this …

We model the idea that when consumers search for products, they first visit the firm whose advertising is more salient …. The gains a firm derives from being visited early increase in search costs, so equilibrium advertising increases as search … costs rise. This may result in lower firm profits when search costs increase. We extend the basic model by allowing for firm …

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 …

We apply the model to the automobile industry. Our search cost … estimate is highly significant and indicates that consumers conduct a limited amount of search. Estimates of own- and cross …

We study a consumer non-sequential search oligopoly model with search cost heterogeneity. We first prove that an … search. We find that the sequence of points on the support of the search cost distribution that can be identified is …, the search cost distribution cannot be identified accurately at quantiles other than the lowest.

First, there is no monotone relationship between prices and the degree of advertising. Second, advertising and search … are “substitutes” for a large range of parameters.
