What is price index number in economics
Price index Numbers: Price index numbers measure the relative changes in prices of a commodity between two periods. Prices can be either retail or wholesale. Price index number are useful to comprehend and interpret varying economic and business conditions over time. Definition of price index: Percentage number that shows the extent to which a price (or a 'basket' of prices) has changed over a period (month, quarter, year) as compared with the price(s) in a certain year (base year) taken as An index number index number is an economic data figure reflecting price or quantity. Index numbers enable use to quickly assess changes in a series of economic data. Some indices are aggregates telling us what is happening to variables such as inflation (i.e. the CPI and the RPI) or share prices (the FTSE100, FTSE250 and so on). An index number is an economic data figure reflecting price or quantity compared with a standard or base value. The base usually equals 100 and the index number is usually expressed as 100 times the ratio to the base value. For example, if a commodity costs twice as much in 1970 as it did in 1960, The Fisher Price Index, also called the Fisher’s Ideal Price Index, is a consumer price index (CPI) used to measure the price level of goods and services over a given period. The Fisher Price Index is a geometric average of the Laspeyres Price Index and the Paasche Price Index. Consumer Price Index (CPI) is a statistic used to measure average price of a basket of commonly-used goods and services in a period relative to some base period. The base period price of the basket is marked to 100 and CPI value hovers above or below 100 to reflect whether the average price has increased or decreased over the period.
