All superlative indices produce similar results and are generally the favored formulas for calculating price indices. [14] A superlative index is defined technically as "an index that is exact for a flexible functional form that can provide a second-order approximation to other twice-differentiable functions around the same point." [15]
A CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically. Sub-indices and sub-sub-indices can be computed for different categories and sub-categories of goods and services, which are combined to produce the overall index with weights reflecting their shares in the total of the consumer expenditures covered by the ...
The Consumer Price Index was initiated during World War I, when rapid increases in prices, particularly in shipbuilding centers, made an index essential for calculating cost-of-living adjustments in wages. To provide appropriate weighting patterns for the index, it reflected the relative importance of goods and services purchased in 92 ...
The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), covers approximately 29 percent of the U.S. population. This index is used predominantly for adjusting Social Security ...
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.
The PCE price index (PePP), also referred to as the PCE deflator, PCE price deflator, or the Implicit Price Deflator for Personal Consumption Expenditures (IPD for PCE) by the Bureau of Economic Analysis (BEA) and as the Chain-type Price Index for Personal Consumption Expenditures (CTPIPCE) by the Federal Open Market Committee (FOMC), is a United States-wide indicator of the average increase ...
The most common type of market basket is the basket of consumer goods used to define the Consumer Price Index (CPI). It is a sample of goods and services, offered at the consumer market. In the United States, the sample is determined by Consumer Expenditure Surveys conducted by the Bureau of Labor Statistics. [1]
The index number problem is the term used by economists to describe the limitation of statistical indexing, when used as a measurement for cost-of-living increases. [7] For example, in the Consumer Price Index, a reference year's "market basket" is assigned an index number of 100.
