The Sensitivity of the True Cost of Living to Price-Induced and Income-Induced Changes in Aggregate Consumers' Tastes
研究了1947年至1981年美国生活成本对价格和收入变化引起的消费者品味变化的敏感性，发现这些效应通常很大，且无法被CPI-U或CPI-W等拉斯派雷斯指数检测到。
This article examines the sensitivity of the cost of living to some aspects of price changes and income changes that cannot be detected by Laspeyres indexes like the CPI-U or CPI-W. Effects of price-induced and income-induced changes in consumers tastes on the cost of living in the United States from 1947 to 1981 are estimated and found to be generally substantial.
