CHAIN WEIGHTED CPI Definition & Legal Meaning

Definition & Citations:

As an alternative to the Consumer Price Index, this measurement is used to remove any biases related to new products, any changes in quality, and discounted pricing. The chain weighted CPI uses both the average changes in the quantity of products purchases, as well as the standard pricing effects. This blend allows for evaluation of situations where customers shift the focus of their purchases from one area of spending to a different area.
