What causes CPI to overstate the true inflation rate?
The CPI may overstate inflation because of substitution, new product, and quality biases. This can happen because of biases, including substitution bias, quality bias, and new-product bias. For example, the fixed basket of goods and services used to find the CPI includes cars.
What are the biases of the CPI?
Biases in the measurement of CPI can occur for four main reasons: (i) the CPI methodology does not capture the ability of consumers to substitute away from more expensive goods in response to changes in relative prices (commodity-substitution bias); (ii) it does not capture the cost savings from shifting to lower- …
What are some reasons that the CPI might not capture the true rate of inflation?
The report asserted that the CPI overstated inflation because of three main reasons: it omitted consumer substitution, did not fully account for quality change, and failed to properly reflect the addition of new goods. BLS has introduced some methodological changes since the report came out in 1996.
Why is CPI inaccurate?
Critics claim that the CPI is inaccurate because it overstates the increases in the cost of living. For this reason, the CPI has been said to be inaccurate. First, consumers do change their spending patterns. Because consumers substitute lower-priced products in lieu of higher-priced ones, the weight has shifted.
Should the CPI consumer price index be replaced by a more accurate measure of inflation?
In other words, the CPI doesn’t measure changes in consumer prices, rather it measures the cost-of-living. So if prices rise and consumers substitute products, the CPI formula could hold a bias that doesn’t report rising prices. Not a very accurate way to measure inflation.

How do you calculate change in price from CPI?
To find the CPI in any year, divide the cost of the market basket in year t by the cost of the same market basket in the base year. The CPI in 1984 = $75/$75 x 100 = 100 The CPI is just an index value and it is indexed to 100 in the base year, in this case 1984. So prices have risen by 28% over that 20 year period.
