A price index aggregates various combinations of base period prices (), later period prices (), base period quantities (), and later period quantities (). Price index numbers are usually defined either in terms of (actual or hypothetical) expenditures (expenditure = price * quantity) or as different weighted averages of price relatives ( p t ...
The Ten-Day Price Index is a procedure under which, “sample prices” with high intra-month fluctuations are selected and surveyed every ten days by phone. Utilizing the data retrieved by this procedure, and with the assumption that other non-surveyed “sample prices” remain unchanged, a “ten-day price index” is compiled and released.
A producer price index (PPI) is a price index that measures the average changes in prices received by domestic producers for their output. Formerly known as the wholesale price index between 1902 and 1978, the index is made up of over 16,000 establishments providing approximately 64,000 price quotations that the U.S. Bureau of Labor Statistics (BLS) compiles each month to represent thousands ...
The U.S. Import and Export Price Indexes measure average changes in prices of goods and services that are imported to or exported from the U.S.. The indexes are produced monthly by the International Price Program (IPP) of the Bureau of Labor Statistics. The Import and Export Price Indexes were published quarterly starting in 1974 and monthly ...
Movements of price indexes from one month to another are expressed as percent changes, rather than as changes in index points. Each index measures price changes from a reference period defined to equal 100.0. Currently, some PPIs have an index base set at 1982 = 100, while the remainder have an index base that corresponds with the month prior ...
The price index for some period is usually normalized to be 1 or 100, and that period is called "base period." A Törnqvist or Törnqvist-Theil price index is the weighted geometric mean of the price relatives using arithmetic averages of the value shares in the two periods as weights. [1]
A Divisia index is a theoretical construct to create index number series for continuous-time data on prices and quantities of goods exchanged. The name comes from François Divisia who first proposed and formally analyzed the indexes in 1926, and discussed them in related 1925 and 1928 works.
