This research investigates the macroeconomic and welfare implications of social security reform in models with aggregate shocks. It is motivated by the observation that the great depression in the U.S. led to an introduction of an unfunded social security system, yet the role of an unfunded social security system for the allocation of intergenerational aggregate risk are not well understood theoretically or quantitatively.A primary goal of this research is to quantitatively evaluate the aggregate economic and welfare effects of a social security reform from a pay-as-you-go to a fully funded system within an overlapping generations model with stochastic production, idiosyncratic uncertainty, and a large number of generations. Given the current debates about reform of the social security system, another goal of this research is to inform policy makers about the trade-offs involved in moving from an unfunded to a funded system of social security in the presence of aggregate economic fluctuations.

本研究探讨了宏观经济和福利的影响， 社会保障改革的总体冲击模型。它的动机是观察到美国的大萧条导致了一个没有资金的社会保障体系的引入，然而，缺乏资金的社会保障体系在代际总风险分配中的作用在理论上和定量上都没有得到很好的理解。本研究的主要目标是定量评估社会保障改革对经济和福利的总影响。在具有随机生产、特质不确定性和大量代的重叠代模型中，进入一个资金充足的系统。考虑到目前关于社会保障制度改革的辩论，本研究的另一个目标是向政策制定者通报在总体经济波动的情况下从无资金社会保障制度向有资金社会保障制度转变所涉及的权衡。
