[摘   要]年金保险是个体应对长寿风险的有效金融工具,但市场需求却普遍不足,在学术界被称为“年金谜题”。本文基于我国各地区人口死亡率与全国平均人口死亡率的差异性,提出了“长寿风险调整年龄”概念,借鉴相对风险厌恶系数,引入个体长寿风险感知系数,测算了中国各地区的长寿风险调整年龄,将长寿风险调整年龄和长寿风险感知系数结合,对个体的长寿风险感知进行度量,并将其带入生命周期模型,模拟个体的年金保险购买行为。结果表明,长寿风险感知较高的个体对年金保险的需求更大,为解释“年金谜题”提供了一个以长寿风险感知为基础的视角,强调了个体长寿风险感知对年金保险需求的影响。

Perception of Longevity Risk and Demand for Annuity Insurance:A Perspective Based on Longevity Risk-Adjusted Age in China

YANG Tian-yu,LV Jin-yun,CHEN Bing-zheng

Abstract:Annuity insurance has long been considered an effective financial instrument for individuals to address longevity risk,yet market demand remains generally insufficient,a phenomenon known as the annuity puzzle in academia.Based on the differences between regional population mortality rates and the national average mortality rate in China,this paper proposes the concept of longevity risk-adjusted age.Drawing on the relative risk aversion coefficient,we introduce an individual longevity risk perception coefficient to calculate the longevity risk-adjusted age across Chinese regions.By combining longevity risk- adjusted age and the longevity risk perception coefficient,we measure individuals’ longevity risk perception and incorporate it into a life-cycle model to simulate individual annuity insurance purchasing behavior.The results show that individuals with higher longevity risk perception have greater demand for annuity insurance.This study provides a longevity risk perception-based perspective to explain the annuity puzzle,emphasizing the impact of individual longevity risk perception on annuity insurance demand.
