摘   要:

This paper develops a theoretical framework to study the technology race in the insurance market. Specifically, we consider a representative customer with a private risk type search among two groups of insurers for insurance coverage —frontier and laggard insurers who are different in the accuracy of their risk-prediction technology. A sequential search setting is considered. That is, the customer pays search costs to learn the products of insurers before making her buying decisions. The customer’s optimal search strategy features a cutoff risk type such that the customer chooses frontier (resp. laggard) insurers for search and buying insurance when her risk type is lower (resp. higher) than the cutoff. Thus, this cutoff risk type measures the frontier and laggard market shares. We show, intuitively, that by improving their technology accuracy, frontier insurers boost their market share. However, it might be ex-ante unexpected that laggard insurers face decreasing market shares when they are catching up with the frontier insurers, but will benefit from technology improvement once they surpass their frontier competitors. Moreover, lowering the customer’s search costs increases the market share of laggard insurers but decreases the market share of frontier insurers. Our results help explain the unclear relationship between technology improvement and market share dynamics observed in practice.
