On the Rate Structure of the American Life Insurance Market
重新审视美国人寿保险市场价格离散问题，用公理化方法构建价格指数，发现价格离散度仅为3.6%，且大部分可由测量误差解释。
ABSTRACT This article re‐examines the conclusion of previous studies that price dispersion is extreme in the American whole life insurance market. We take an axiomatic approach to the problem of measuring “price” dispersion in the market for the multiparameter whole life contracts, studying the distribution across contract offers of a price index which is uniquely determined by two conditions. In contrast to the accepted wisdom, we find that the derived measure of price dispersion is only 3.6% and that much of this dispersion can be accounted for by measurement error.
