Optimal Retirement Policies with Present-Biased Agents
将准双曲贴现引入Mirrlees税收模型，研究政府如何利用时间不一致性筛选不同生产率代理人，并通过退休储蓄账户和社会保障实施最优机制。
Abstract This paper incorporates quasi–hyperbolic discounting into a Mirrlees taxation model to study the design of retirement policies for present-biased agents. I show that the government can improve the screening of productivity by exploiting time inconsistency. This is done by providing commitment to sophisticated agents and taking advantage of the incorrect beliefs of naïve agents. This can be achieved even if the degrees of present bias and sophistication are private information. I also demonstrate how the government can implement the optimal mechanism using retirement savings accounts and social security benefits.
