I develop an integrated utility-maximizing model in which consumers decide over which and how many companies to search and from which company to purchase. My modelling approach rationalizes observed consideration sets as being the outcomes of consumers' search processes. I find search costs to range from $35 to $170 and average switching costs of $40. Search costs are the most important driver of customer retention and their elimination is the main lever to increase consumer welfare in the auto insurance industry.©2014 RANDEconomicsAutomobile insuranceSearching costsSwitching costsarticleHonka, Elisabeth. 2014.
