Inflation in India

Ever wondered why in India we calculate inflation based on WPI while all other countries use the CPI.

Here's the answer :

"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."
