Ability, Promotion, and Optimal Retirement
构建模型分析工人生产率如何受经验、能力和职位影响，并基于比较优势进行职位分配，推导出工人退休的最优时机。
This article considers a model in which the productivity of a worker depends on his experience, ability, and position in the firm. It is shown that workers are sorted in positions based on comparative advantage. Furthermore, workers are induced to retire when productivity is equal to the value of time after adjusting for the reallocation of other workers by positions that would occur if the worker retired.
