 note = {Each insurance product per se is identical but the insurance companies that sell this identical insurance product are not necessarily identical. Because the nature of insurance is to cover damages from accidents, for example, consumers hope to get their insurance moneys quickly from their insurance companies when accidents happen. In this study, this is interpreted as “aftercare” and all insurance companies incorporate it into their strategies. The insurance companies in the market are assumed to compete not only on price (insurance rate) but also on quality (level of aftercare). Thus, it is natural that the insurance market is assumed to have vertical differentiation., Journal of Insurance and Risk Management, Vol.3, Issue 6, pp.45-68, June 2005.},
