Because of the important role that survival expectations play in individual decision making, we investigate the extent to which individual responses to survival probability questions are informative about actual mortality. In contrast to earlier studies, which relied on the Health and Retirement Study (HRS) of US individuals aged 50 and over, we combine household survey data on subjective survival probabilities with administrative data on actual mortality for Dutch respondents aged 25 and over. Our main finding is that in our sample, individual life expectancies (measured as subjective survival probabilities) do predict actual mortality even when we control for a large set of health indicators. Our results further suggest that, on average, women underestimate their remaining life duration, whereas men tend to predict their survival chances more realistically. Both sexes, however, tend to overestimate the age gradient in mortality risk and underestimate the health risks of smoking.
由于生存预期在个体决策中发挥着重要作用,我们研究了个体对生存概率问题的回答在多大程度上能反映实际死亡率。与早期依赖美国50岁及以上人群的健康与退休研究(HRS)的研究不同,我们将关于主观生存概率的家庭调查数据与荷兰25岁及以上受访者实际死亡率的行政数据相结合。我们的主要发现是,在我们的样本中,即使我们控制了大量健康指标,个体预期寿命(以主观生存概率衡量)确实能预测实际死亡率。我们的结果进一步表明,平均而言,女性低估了她们剩余的寿命时长,而男性往往能更现实地预测自己的生存机会。然而,两性都倾向于高估死亡率风险中的年龄梯度,并低估吸烟的健康风险。
