Inequality in wealth among elderly households, and in particular the prevalence of very low wealth holdings, can be an important consideration in the design of social insurance programs. This paper examines the incidence and determinants of low levels of financial and total wealth using repeated cross-sections of the Health and Retirement Study (HRS) and a small longitudinal sample of HRS respondents observed both at age 65 and shortly before death. Most of those who report very low wealth holdings at the end of their life had little wealth at the traditional retirement age of 65. There is strong persistence over time in reports of very low wealth, and more generally relatively little evidence that wealth is drawn down in the first 15 years of retirement. The age-specific probability of reporting low wealth increases slowly after age 65. Low lifetime earnings are strongly predictive of low wealth at retirement and at the end of life. The post-retirement onset of a major medical condition, and, for married women, the loss of their spouse, are both associated with small increases in the probability of reporting very low wealth, but they account for a small fraction of low-wealth outcomes. Low levels of wealth accumulation before age 65, rather than gaps in the safety net after 65 or rapid spend-down of accumulated assets, appear to be the primary determinant of low levels of wealth just before death.
老年家庭财富不平等,尤其是极低财富持有率的普遍存在,可能是社会保险项目设计中的一个重要考量因素。本文利用健康与退休研究(HRS)的重复横截面数据以及一个对65岁时和临终前不久进行观察的HRS受访者的小型纵向样本,研究了低水平金融财富和总财富的发生率及决定因素。大多数在生命结束时报告极低财富持有量的人在传统退休年龄65岁时几乎没有财富。极低财富报告在时间上具有很强的持续性,更普遍地说,几乎没有证据表明在退休后的头15年里财富被消耗掉。65岁以后,报告低财富的特定年龄概率缓慢上升。低终身收入强烈预示着退休时和生命结束时的低财富水平。退休后出现重大疾病,以及对于已婚女性来说,配偶的去世,都与报告极低财富的概率小幅上升有关,但它们在低财富结果中所占比例很小。65岁之前财富积累水平低,而非65岁之后安全网的缺口或积累资产的快速消耗,似乎是临终前低财富水平的主要决定因素。
