Price Indexes

Price indexes are a normalized average of prices for a given class of goods or services in a given region, during a given interval of time. It is a statistic designed to help to compare how these prices, taken as a whole, differ between time periods or geographical locations.
Price indices have several potential uses. For particularly broad indices, the index can be said to measure the economy's price level or a cost of living. More narrow price indices can help producers with business plans and pricing. Sometimes, they can be useful in helping to guide investment. (Source: Wikipedia)
Some of the major price indexes are listed below:

Wholesale Price Index (WPI): The index is used to measure the change in the average price level of goods traded in wholesale market. A total of 435 commodity prices make up the index. It is available on a weekly basis, with the shortest possible measurement lag being two weeks. Because of this, it is widely used in business and industry circles and in Government, and is generally taken as an indicator of the inflation rate in the economy.

Producer Price Index (PPI): It measures average changes in prices received by domestic producers for their output. It is one of several price indices calculated by national statistical agencies.

Consumer Price Index (CPI): It is a measure of the average price of consumer goods and services purchased by households. A consumer price index measures a price change for a constant market basket of goods and services from one period to the next within the same area (city, region, or nation). The percent change in the CPI is a measure of inflation. The CPI can be used to index (i.e., adjust for the effects of inflation) wages, salaries, pensions, and regulated or contracted prices. They are weighted this way: Housing: 41.4%, Food and Beverage: 17.4%, Transport: 17.0%, Medical Care: 6.9%, Others: 6.9%, Apparel: 6.0%, Entertainment: 4.4%. Taxes (43%) are not included in CPI computation.

By August 2010, the Indian government will have a new Consumer Price Index, in order to address a situation of increasing prices to rise even as the inflation rate is tending towards zero, the government has initiated action to introduce a new consumer price index (CPI) by August next year. The new index would be available with four sub-sections to reflect prices at national, rural, urban and state levels on monthly basis. The data collection for rural as well as urban India would start by July, and the new CPI would be out exactly one year after that in August, 2010. This would be done by engaging 2,400 postmen for collection of retail price from 1,200 villages in the country by June end. The postmen would be identified in May and trained them in June. Preparation for the new CPI for urban India has been completed in March. The CSO is ready for collecting data from retail outlets in 100 cities and town.
