Abstract: This paper describes the major methods used by statistical agencies to adjust for differences in the quality of a good or service when one item replaces another in a sample used to construct a Consumer Price Index. The methods are categorized as either direct, including the production-cost and hedonic approaches, or indirect, such as linking or class-mean imputation. The paper also presents simplified example calculations showing how the methods are applied in practice.
