Definition of price index in English English dictionary
A statistical estimate of the level of prices of some class of goods or services
Current price expressed as a proportion to the same price in an earlier time period, commonly called the base period Monthly price indexes computed by the National Agricultural Statistics Service are the index of prices received by farmers and the index of prices paid by farmers for commodities and services, interest, taxes, and farm wage rates The ratio of these two indexes is referred to as the parity ratio
A number relating prices of a group of commodities to their prices during an arbitrarily chosen base period. a list of particular goods and services and how much their prices change each month retail price index. Measure of change in a set of prices, consisting of a series of numbers arranged so that a comparison of the values for any two periods or places will show the change in prices between periods or the difference in prices between places. Price indexes were first developed to measure changes in the cost of living in order to determine the wage increases necessary to maintain a constant standard of living. There are two basic types. Laspeyres-type indexes define a market basket of goods in a base period, then use the prices for those goods to examine change over space and time. In its simplest form, this is simply the ratio of what those goods cost today to what they cost in the base period. The two most familiar indexes of this type are the consumer price index (CPI) and the producer price index (PPI). The CPI measures changes in retail prices in such component parts as food, clothing, and shelter. The PPI (formerly called the wholesale price index) measures changes in the prices charged by manufacturers and wholesalers. Paasche-type indexes define a market basket of goods in the current period, then use the prices of those goods from past periods. The most familiar index of this type is the GDP deflator, used in the U.S. in the national income accounting to differentiate amounts in constant dollars from those in current dollars
a measure of the level of prices found by comparing the cost of a certain basket of goods in one year with that cost in a base year
A measurement that attempts to provide a measure of the trend in prices paid for a certain bundle of goods and services over time
a measure of the level of prices found by comparing the cost of a certain basket of goods in one year with the cost in a base year
An indicator, derived by aggregating sets of representative unit prices with an appropriate weighting base, which measures changes in price levels over time Price indexes are stated in terms of a base point of time where the price level is arbitrarily set at 100
an index that traces the relative changes in the price of an individual good (or a market basket of goods) over time
a measure of the level of prices found by comparing the cost of a certain basket of goods in one year with the cost in a base year (Stiglitz and Boadway,1994)
An index of prices used to measure the change in the cost of basic goods and services in comparison with a fixed base period. Also called cost-of-living index. a list of the prices of products that shows how much prices have increased during a particular period of time. Measure of living costs based on changes in retail prices. Consumer price indexes are widely used to measure changes in the cost of maintaining a given standard of living. The goods and services commonly purchased by the population covered are priced periodically, and their prices are combined in proportion to their relative importance. This set of prices is compared with the initial set of prices collected in the base year to determine the percentage increase or decrease. The population covered may be restricted to wage and salary earners or to city dwellers, and special indexes may be used for special population groups (e.g., retirees). Such indexes do not take into account shifts over time in what the population buys; when modified to take subjective preferences into account, they are called constant-utility indexes. Consumer price indexes are available for more than 100 countries
The retail price index is a list of the prices of typical goods which shows how much the cost of living changes from one month to the next. The retail price index for September is expected to show inflation edging up to about 10.8 per cent. the retail price index a list of certain goods and services and how much their prices change each month
