本文解释了四种“价格指数化”的初始社会保障退休福利的方法，并讨论了每种方法对社会保障的财政可持续性，福利水平和替代率，再分配以及系统财务对人口和经济冲击的敏感性的影响。在这些方法中，主要保险金额（PIA）因素指数将产生最大的成本节约，同时以几乎相同的速度降低所有收入水平的福利增长。将平均指数化月收入指数化的方法、“弯曲点”公式或两者都采用的方法，将以较慢的速度减少福利增长，并将对福利分配和系统可持续性产生不同的影响。
This paper explains four methods of "price indexing" initial Social Security retirement benefits, and discusses the effect of each method on the fiscal sustainability of Social Security, benefit levels and replacement rates, redistribution, and sensitivity of system finances to demographic and economic shocks. Of these methods, Primary Insurance Amount (PIA) Factor Indexing would generate the largest cost savings while reducing benefit growth at approximately an equal rate for all income levels. Methods that index the Average Indexed Monthly Earnings (AIME), the formula "bend points," or both, would reduce benefit growth at a slower rate and would have different effects on benefit distribution and system sustainability.
