The behavioral economics literature suggests that exposure to traumatic events shifts preference features including risk aversion and time preference. In this study, we examined the association between traumatic life events and self-control in old age. Data were obtained from the Health and Retirement Study, which offers retrospective data on trauma exposure and early life characteristics. The results showed that experiences of serious physical attacks or assaults is associated with a 3.1% reduction in self-control, adjusted for demographic and childhood socioeconomic characteristics. The attacks or assaults were experienced approximately 30 years prior to the survey, indicating that traumatic life events exert a lasting influence on self-control. Further analyses found no difference in the association between the experience of serious physical attacks or assaults and self-control according to the timing of occurrence. Our findings are consistent with the evidence that experiences of natural disasters or armed conflicts increase impatience among survivors.
行为经济学文献表明，创伤事件的暴露会改变偏好特征，包括风险规避和时间偏好。在这项研究中，我们研究了创伤性生活事件与老年人自我控制之间的关系。数据来自健康与退休研究，该研究提供了关于创伤暴露和童年社会经济特征的回溯数据。结果表明，严重的身体攻击或袭击经历与自我控制能力下降 3.1%有关，这一结果经过了人口统计学和儿童时期社会经济特征的调整。这些攻击或袭击大约发生在调查前 30 年，表明创伤性生活事件对自我控制能力有着持久的影响。进一步的分析发现，根据发生时间的不同，严重身体攻击或袭击经历与自我控制之间的关联没有差异。我们的研究结果与以下证据一致，即自然灾害或武装冲突的经历会增加幸存者的急躁情绪。
