标题： Who Are I: Time Inconsistency and Intrapersonal Conflict and Reconciliation

摘要： 时间不一致性在动态选择问题中很普遍：今天对一个代理而言最优的未来行动计划可能在未来对同一代理来说并不最优。 如果代理意识到这种内在冲突，但无法在未来承诺遵循今天的最优计划，那么她今天理性的策略是与未来的自己达成和解，即正确预期她在未来的行为，然后据此今天采取行动。 这种策略被称为内在均衡，并且自20世纪50年代以来就已经被研究。 然而，在连续时间环境下严谨的处理直到十年前才出现。 从那时起，关于连续时间中时间不一致问题的内在均衡研究迅速发展。 在本章中，我们回顾了该文献中的经典结果和一些最新进展。 显示英文摘要

摘要： Time inconsistency is prevalent in dynamic choice problems: a plan of actions to be taken in the future that is optimal for an agent today may not be optimal for the same agent in the future. If the agent is aware of this intra-personal conflict but unable to commit herself in the future to following the optimal plan today, the rational strategy for her today is to reconcile with her future selves, namely to correctly anticipate her actions in the future and then act today accordingly. Such a strategy is named intra-personal equilibrium and has been studied since as early as in the 1950s. A rigorous treatment in continuous-time settings, however, had not been available until a decade ago. Since then, the study on intra-personal equilibrium for time-inconsistent problems in continuous time has grown rapidly. In this chapter, we review the classical results and some recent development in this literature.
