通过有效地与工资或利率挂钩的现收现付制社会保障制度，代际分担风险的福利效应被量化。与当前的美国制度相比，与稳定状态相比，出生在一个高效分担风险的经济体中可以获得巨大的福利收益。有效的政策涉及在整个生命周期中不断增加风险的税收净额。当考虑到调整到稳定状态时，福利收益很大程度上变成了负值。还将结果与第一个最佳分配进行了比较和对比。
The welfare effects of intergenerational risk sharing through a pay-as-you-go social security system that is efficiently indexed to wages or interest rates are quantified. Comparing steady states, there are large welfare gains of being born into an economy with efficient risk sharing as compared to the current U.S. system. Efficient policy involves an increasingly risky net of tax income over the life cycle. When adjustment to steady state is taken into account, the welfare gains largely turn negative. The results are also compared and contrasted to the first best allocation.
