It is often argued that price indexes do not fully capture the quality improvements of new goods in the market.

The hedonic quality adjustment method removes any price differential attributed to a change in quality by adding or subtracting the estimated value of that change from the price of the old item. Hedonic quality adjustments for rent and owners equivalent rent are used primarily to adjust for the age of a rental unit, and for utility adjustments.
The Consumer Price Index (CPI) for food is a component of the all-items CPI. The CPI measures the average change over time in the prices paid by urban consumers for a representative market basket of consumer goods and services. One such measure is the price index associated with the nation’s gross domestic product (GDP). Each quarter, BEA releases data on the level of, and change in, GDP. These data include a breakdown of GDP into price and quantity indexes, as well as a GDP implicit price deflator. To begin with, let’s look solely at the Consumer Price Index. The CPI can be viewed as a number used to measure change. In the United States, the Bureau of Labor Statistics gathers the average prices paid by consumers for hundreds of different items each month. The average is then compared to a reference base period.
Therefore, the consumer price index has to be adjusted on a regular basis to reflect these changes. However, there is no bulletproof method to measure the increase in quality (or its value), which makes it difficult to include the value increase in the consumer price index accurately. 4) Lack of Individual Relevance
The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. Indexes are available for the U.S. and various geographic areas. Average price data for select utility, automotive fuel, and food items are also available. The hedonic quality adjustment method removes any price differential attributed to a change in quality by adding or subtracting the estimated value of that change from the price of the old item. Hedonic quality adjustments for rent and owners equivalent rent are used primarily to adjust for the age of a rental unit, and for utility adjustments. Price index, measure of relative price changes, consisting of a series of numbers arranged so that a comparison between the values for any two periods or places will show the average change in prices between periods or the average difference in prices between places. DSTI/DOC(2004)9 20 competitive in the price/quality dimension with the new computer, n. Then, since Pmt is in the denominator of the expression for Ao, and is too high (relative to the quality of computer m), Rt (=Ao ) < A*, where A* designates the correct quality adjustment. Consumer Price Index (CPI) The most commonly reported measure of the consumer price levels in the United States is the Consumer Price Index (CPI). Published by the U.S. Department of Labor 's Bureau of Labor Statistics, the CPI is a fixed-weight price index using a fixed basket of goods that are representative of what a typical consumer purchases each month. A price index ( plural: "price indices" or "price indexes") is a normalized average (typically a weighted average) of price relatives for a given class of goods or services in a given region, during a given interval of time. It is a statistic designed to help to compare how these price relatives, taken as a whole, The Consumer Price Index measures the average change in prices over time that consumers pay for a basket of goods and services. CPI is widely used as an economic indicator. It is the most widely used measure of inflation and, by proxy, of the effectiveness of the government’s economic policy.
