报告摘要: Many empirical studies confirm that policyholder's subjective mortality beliefs deviate from the information given by publicly available mortality tables. In this study, we look at the effect of subjective mortality beliefs on the perceived attractiveness of retirement products, focusing on conventional annuities and tontines (where a pool of policyholders shares the longevity risk). Given actuarially fair pricing with no subjective mortality beliefs (that is, the insurer's and the policyholder's perceptions coincide), annuities yield higher lifetime utility than tontines (see Milevsky and Salisbury (2015)). Staying in an actuarially fair pricing framework, we find that this result might be reversed if the policyholder's subjective survival probabilities for her peers are lower than the ones used by the insurance company. For this result, the subjective belief to live longer or shorter than one's peers does not play a major role.
