The Effects of Pensions and Retirement Policies on Retirement in Higher Education
利用1970年代26所高质量私立大学终身男教授的数据，模拟提高并废除强制退休年龄后，60多岁和70多岁教授全职工作大幅增加，且早期退休激励计划仅能抵消一小部分增长，其产生的租金超过节省的成本。
A structural retirement model is estimated using data for tenured, male faculty employed in the 1970's at 26 high quality private colleges and universities. Simulations of raising and then abolishing the mandatory retirement age suggest very large increases in full time work by faculty members in their late 60's and early 70's. Simulations also suggest that early retirement incentive programs would offset only a small fraction of the increase in work due to changes in mandatory retirement, and that rents created by these programs exceed savings from induced early retirements, with salaries of replacements further adding to costs.
