This paper provides a method to estimate search costs in an environment in which consumers are uncertain about the … provides bounds on the search costs that can rationalize observed search and purchasing behavior. Using individual …-specific data on web browsing and purchasing behavior for electronics sold online we show how to use these bounds to estimate search …

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 …

We use novel data on consumer click-stream behavior from a major …-based ranking, our model accounts for the rapidly changing prices that characterize the hotel industry, consumers' expected search …

In a recent paper Hong and Shum [2006. Using price distributions to estimate search costs. Rand Journal of Economics 37 …, 257–275] present a structural method to estimate search cost distributions. We extend their approach to the case of … oligopoly and present a new maximum likelihood method to estimate search costs. We apply our method to a data set of online …
