This paper proposes a new framework to discuss self-control problems in the context of life-cycle health and longevity. Individual decisions are conceptualized as the partial control of impulsive desires of a short-run self by a rationally forward-looking long-run self. The short-run self strives for immediate gratification through consumption of health-neutral and unhealthy goods. The long-run self reflects the long-term consequences of unhealthy behavior on health outcomes and longevity and invests time and money to improve current and future health. The model is calibrated with data from the United States and used to provide an assessment of the impact of imperfect self-control on unhealthy consumption, health investments, lifetime health, and the age at death.
本文提出了一个新的框架，讨论生命周期健康和长寿背景下的自我控制问题。个体决策被概念化为短期自我对冲动欲望的部分控制，而理性前瞻性的长期自我则对冲动欲望进行控制。短期自我通过消费健康中性和不健康的商品来追求即时满足。长期自我反映了不健康行为对健康结果和寿命的长期影响，并投入时间和金钱来改善当前和未来的健康。该模型使用美国的数据进行校准，并用于评估自我控制不完美对不健康消费、健康投资、终身健康和死亡年龄的影响。
