Abstract:     
We show that the search method consumers use when resolving uncertainty in the prices of alternatives is identified in data where consumers' consideration sets (but not the sequence of searches), prices for the considered alternatives and market-wide price distributions are observed. We show that identification comes from differences in the patterns of actual prices in consumers' consideration sets across search methods. We also provide a new estimation approach for the sequential search model; complementing earlier work that has estimated a simultaneous search model with such data. Using a novel data set on consumer shopping behavior in the U.S. auto insurance industry that contains information on consideration sets and choices, we find that the pattern of actual prices in consumers' consideration sets are consistent with consumers searching simultaneously. Our counterfactuals show that the consideration set and purchase market shares of the largest insurance companies are overpredicted under the incorrect assumption of sequential search. As the search method affects consumers' consideration sets, which in turn influence brand choices, understanding the nature of consumer search and its implications for consideration and choice is important from a managerial perspective.
