Although income and wealth are frequently used as indicators of well-being, they are increasingly augmented with subjective measures such as life satisfaction to capture broader dimensions of the well-being of individuals. Based on large surveys of individuals, life satisfaction in cross-section often is found to increase with age beyond retirement into advanced old age. It may seem puzzling that average life satisfaction does not decline at older ages because older individuals are more likely to experience chronic or acute health conditions, or the loss of a spouse. Accordingly, this empirical pattern has been called the "paradox of well-being." We examine the age profile of life satisfaction of the U.S. population age 65 or older in the Health and Retirement Study (HRS), and find that in cross-section it increases between age 65 and 71 and is flat thereafter; but based on the longitudinal dimension of the HRS, life satisfaction significantly declines with age and the rate of decline accelerates with age. We reconcile the cross-section and longitudinal measurements by showing that both differential mortality and differential non-response bias the cross-sectional age profile upward: individuals with higher life satisfaction and in better health tend to live longer, and, among survivors, individuals with higher life satisfaction are more likely to remain in the survey, masking the decline in life satisfaction experienced by individuals as they age. We conclude that the optimistic view about increasing life satisfaction at older ages based on cross-sectional data is not warranted.
尽管收入和财富经常被用作幸福的指标,但它们越来越多地被诸如生活满意度等主观指标所补充,以涵盖个人幸福更广泛的维度。基于对个人的大规模调查,人们经常发现,在横截面数据中,退休后的生活满意度会随着年龄增长到高龄阶段而提高。老年人的平均生活满意度并未下降,这似乎令人费解,因为老年人更有可能经历慢性或急性健康问题,或失去配偶。因此,这种实证模式被称为“幸福悖论”。我们研究了健康与退休研究(HRS)中65岁及以上美国人口的生活满意度年龄分布,发现在横截面数据中,生活满意度在65岁至71岁之间上升,之后趋于平稳;但基于HRS的纵向维度,生活满意度随年龄显著下降,且下降速度随年龄加快。我们通过表明差异死亡率和差异无应答偏差都会使横截面年龄分布向上偏误,从而调和了横截面和纵向测量结果:生活满意度较高且健康状况较好的个体往往寿命更长,而且在幸存者中,生活满意度较高的个体更有可能留在调查中,掩盖了个体随着年龄增长而经历的生活满意度下降。我们得出结论,基于横截面数据对老年人生活满意度上升的乐观看法是没有根据的。
