Social Security Taxation and Intergenerational Risk Sharing
分析社会保障体系对私人储蓄、劳动选择和福利的影响，指出非完全基金制可改变储蓄率，作为实现黄金增长路径的政策工具。
The life cycle hypothesis has become the dominant mode used to analyze the effects of a social security system on private saving, the labor/leisure choice, and social welfare. As both Barro and Samuelson indicate, a fully funded Social Security program (in a world of certainty) would drive out an equivalent amount of private saving. If the interest rate is r, the effects of a payment of a dollar into the social security pool while young would just offset* the effects of receiving (1+r) dollars as a transfer when retired. Papers by Diamond, Hi», and Samuelson, among others, have examined the effects of non-fully funded Social Security schemes in a growing economy. A non-fully funded program can be used to alter the private sector's saving rate and, hence, the capital/labor ratio. Social Security, then, can be used as a policy tool for achieving the (or some variant of the) golden rule growth path.
