We explore the impact of information technology on the level of premiums paid for individual health insurance by asking which kinds of buyers will have larger gains from the use of new technology. We compare 'asking price' data posted on an electronic insurance exchange with survey data on premiums actually paid before the advent of exchange and examine whether the pattern of differences between asking prices and transactions prices can be explained using a simple search theory. We hypothesize that older consumers, expecting to pay higher premiums for a given policy, had engaged in more intensive search than younger consumers, given the same distribution of prices and search costs. Therefore, the introduction of an electronic exchange that lowers the cost of search should have a larger effect on decreasing the level of premiums paid for those who previously searched less (i.e., younger consumers). We find evidence consistent with this hypothesis.
