The Impact of Age Pension Eligibility Age on Retirement and Program Dependence: Evidence from an Australian Experiment
研究了1993年澳大利亚养老金改革（女性领取年龄从60岁逐步提高到65岁）对退休决策和替代性福利项目使用的影响，发现提高领取年龄显著降低退休概率，并导致更多人转向残疾支持养老金。
Governments around the world are reforming their social security systems in light of the challenges posed by population aging. We study the 1993 Australian Age Pension reform, which progressively increased the eligibility age for women from 60 to 65 years. We find economically significant responses to the reform. An increase in the eligibility age of one year induced a decline in the probability of retirement by 12 to 19 percentage points. In addition, the reform induced significant program substitution, with increases in enrollment in other social insurance programs, particularly the disability support pension, which effectively functioned as an alternative source of retirement income. © 2015 The President and Fellows of Harvard College and the Massachusetts Institute of Technology
