Optimal timing of retirement is an important part of retirement planning. We consider three types of individuals distinguished by the way they use information when deciding the retirement time. For each of these types, we analyze two elements influencing the decision, the market model and the mortality model, and we study the impact of working with one combination or another. Based on analytical solutions to almost all the combinations, we reach a conclusion, even relevant for practical advice: Young individuals must prioritize the market model over the mortality model while for older individuals, it is the other way around.

关于退休时间的决策

最佳退休时间是退休计划的重要组成部分。在确定退休时间时，我们考虑了三种类型的个人，这些个人的区别在于他们使用信息的方式。对于每种类型，我们分析影响决策的两个因素，即市场模型和死亡率模型，并研究使用一种或另一种组合的影响。基于对几乎所有组合的分析解决方案，我们得出一个结论，甚至与实用建议相关：结论：年轻人必须优先考虑市场模型而不是死亡率模型，而对于老年人则必须相反。
