Answer 1

India uses the Wholesale Price Index (WPI) to calculate and then decide the inflation rate in the economy.

Wholesale Price Index (WPI)

WPI was first published in 1902, and was one of the more economic indicators available to policy makers until it was replaced by most developed countries by the Consumer Price Index in the 1970s.

WPI is the index that is used to measure the change in the average price level of goods traded in wholesale market. In India, a total of 435 commodities data on price level is tracked through WPI which is an indicator of movement in prices of commodities in all trade and transactions. It is also the price index which is available on a weekly basis with the shortest possible time lag only two weeks. The Indian government has taken WPI as an indicator of the rate of inflation in the economy.

Consumer Price Index (CPI)

CPI is a statistical time-series measure of a weighted average of prices of a specified set of goods and services purchased by consumers. It is a price index that tracks the prices of a specified basket of consumer goods and services, providing a measure of inflation.

\CPI is a fixed quantity price index and considered by some a cost of living index. Under CPI, an index is scaled so that it is equal to 100 at a chosen point in time, so that all other values of the index are a percentage relative to this one.

Economists Shunmugam and Prasad say it is high time that India abandoned WPI and adopted CPI to calculate inflation.

India is the only major country that uses a wholesale index to measure inflation. Most countries use the CPI as a measure of inflation, as this actually measures the increase in price that a consumer will ultimately have to pay for.

"CPI is the official barometer of inflation in many countries such as the United States, the United Kingdom, Japan, France, Canada, Singapore and China. The governments there review the commodity basket of CPI every 4-5 years to factor in changes in consumption pattern," says their research paper.

It pointed out that WPI does not properly measure the exact price rise an end-consumer will experience because, as the same suggests, it is at the wholesale level.

The paper says the main problem with WPI calculation is that more than 100 out of the 435 commodities included in the Index have ceased to be important from the consumption point of view.

Take, for example, a commodity like coarse grains that go into making of livestock feed. This commodity is insignificant, but continues to be considered while measuring inflation.

India constituted the last WPI series of commodities in 1993-94; but has not updated it till now that economists argue the Index has lost relevance and can not be the barometer to calculate inflation.

Shunmugam says WPI is supposed to measure impact of prices on business. "But we use it to measure the impact on consumers. Many commodities not consumed by consumers get calculated in the index. And it does not factor in services which have assumed so much importance in the economy," he pointed out.

But why is India not switching over to the CPI method of calculating inflation?

Finance ministry officials point out that there are many intricate problems from shifting from WPI to CPI model.

First of all, they say, in India, there are four different types of CPI indices, and that makes switching over to the Index from WPI fairly 'risky and unwieldy.' The four CPI series are: CPI Industrial Workers; CPI Urban Non-Manual Employees; CPI Agricultural labourers; and CPI Rural labour.

Secondly, officials say the CPI cannot be used in India because there is too much of a lag in reporting CPI numbers. In fact, as of May 21, the latest CPI number reported is for March 2006.

The WPI is published on a weekly basis and the CPI, on a monthly basis.

And in India, inflation is calculated on a weekly basis.
