The Common-Scaling Social Cost-of-Living Index
提出一种名为“共同缩放”的社会生活成本指数，解决因个人偏好或预算不同导致的加总问题，并用非参数方法估计该指数，应用于1988-2000年美国社会生活成本变化分析。
If preferences or budgets are heterogeneous across people (as they clearly are), then individual cost-of-living indexes are also heterogeneous. Thus, any social cost-of-living index faces an aggregation problem. In this article, we provide a solution to this problem that we call a “common-scaling” social cost-of-living index (CS-SCOLI). In addition, we describe nonparametric methods for estimating such social cost-of-living indexes. As an application, we consider changes in the social cost-of-living in the U.S. between 1988 and 2000.
