Consumer Prices, the Consumer Price Index, and the Cost of Living
CPI委员会重申消费者价格指数每年存在1.1个百分点的向上偏差,并反驳了关于质量调整不足、新产品仅惠及富人以及调整不可行的观点,提出了减少偏差的具体方法。
After presenting major findings and recommendations, the CPI Commission reiterates the estimate of a 1.1 percentage point per annum upward bias. It rejects the contention that the BLS already makes substantial corrections for quality change; that quality improvements and new products accrue only to the rich; and that procedures to make more extensive quality adjustments, valuations of new products, and adjustments for commodity and outlet substitution are impractical. The bias in the CPI can be sharply reduced, as the authors detail in this paper. Coauthors are Ellen R. Dulberger, Robert J. Gordon, Zvi Griliches, and Dale W. Jorgenson.
