For example, suppose for a single item the average of prices in the first set was $15 and for the second set was $30. Then, designating first set as the reference set gives an index of 200.0 (30/15x100) for the comparison second set. index (C-CPI-U), also know as Tornqvist’s chained consumer price index.3 The CPI-U divides the medical price index into medical care-commodities and medical care-services, but they are both lower than the combined price index of medical care in the CPI-E. For example, as shown in Table 2, the CPI-E for medical care was 333 in 2004, compared to Set the price index to 1 in the first period. Compute the price index for the second period and chain it with the first period, P2 chain = P1 chain × P (p1, p2, q1, q2), where P (p1, p2, q1, q2) is any bilateral index number formula. 1.1 A price index is a measure of the proportionate, or percentage, changes in a set of prices over time. A consumer price index (CPI) measures changes in the prices of goods and services that households consume. Such changes affect the real purchasing power of consumers’ incomes and their welfare. FPI is often called the real index as it corrects for the upward bias of the Laspeyres Price Index and the downward bias of the Paasche Price Index by taking the geometric average of the two weighted indices.
