The latest WPI has a basket of 676 items with
5482 quotations. The major criticism for this index is
that 'the general public does not buy at the wholesale level',
thus WPI does not give the actual feeling of the amount of pressure borne by
the general public. However, the increase in wholesale prices
does affect the retail prices and as such give some feel of the consumer
prices.
Consumer Price Index (CPI)
The CPI measures price change from the
perspective of the retail buyer. It is the real index for the common people. It
reflects the actual inflation that is borne by the individual. CPI is
designed to measure changes over time in the level of retail prices of selected
goods and services on which consumers of a defined group spend their
incomes. Till January 2012, in India there were only
following four CPIs compiled and released on national level.
(In some countries like UK, Malaysia, Poland it is also known as Retail Price
Index).
(1) Industrial Workers (IW) (base 2001),
(2) Agricultural Labourer (AL) (base 1986-87)
and
(3) Rural Labourer (RL) (base 1986-87)
(4) Urban Non-Manual Employees (UNME) (base
1984-85),
The first three are compiled by the Labour Bureau in
the Ministry of Labour and Employment, and the fourth is compiled by Central
Statistical Organisation (CSO) in the Ministry of Statistics and Programme
Implementation. These four CPIs reflect the effect of price
fluctuations of various goods and services consumed by specific segments of
population in the country. These indices did not encompass all the
segments of the population and thus, did not reflect the true picture of the
price behaviour in the country as a whole.
New Series of CPI Started in 2012
Therefore, there was a strong feeling that there is
a need for compiling CPI for entire urban and rural population of the
country to measure the inflation in Indian economy based on
CPI. Thus, now Central Statistics Office (CSO) of the
Ministry of Statistics and Programme Implementation has started compiling a new
series of CPI for with the following measures:
(a) CPI for the entire urban
population viz CPI (Urban);
(b) CPI for the entire rural
population viz CPI (Rural)
(c) Consolidated CPI for Urban +
Rural will also be compiled based
on above two CPIs
These would reflect the changes in the price
level of various goods and services consumed bythe Urban and rural
population. These new indices are now compiled at State / UT and
all India levels.
The CPI inflation series is wider in scope than the
one based on the wholesale price index (WPI), as it has both rural and urban
figures, besides state-wise data. The new series, with 2010 as the base year,
also includes services, which is not the case with the WPI series.
However, this new series will become comparable only in 2013 when the data for
2012 will also be available for comparison.
A comparison of this new series with WPI is given

Producer Price Indexes (PPI) –
These are indices that measure the average change
over time in selling prices by producers of goods and services. They measure price
change from the point of view of the seller. Majority of OECD countries
measure inflation based on Producer Price Indiex (PPI) while only some others
use WPI. Countries like Japan, Greece, Norway and Turkey use
WPI. Already WPI has been replaced in most of the countries by PPI
due to the broader coverage provided by the PPI in terms of products and
industries and the conceptual concordance between PPI and system the national
account. PPI is considered to be more relevant and technically
superior compared to one at wholesale level. However, in India we
are still continuing with WPI.
Cost-of-living indices (COLI):
This is different from CPI. This index
aims to measure the effects of price changes on the cost of achieving a
constant standard of living (i.e. level of utility or welfare) as distinct from
maintaining the purchasing power to buy a fixed consumption basket of good and
services. Maintaining a constant standard of living does not imply
continuing to consume a fixed basket of goods and services. A COLI allows for
the fact that households who seek to maximize their welfare from a given
expenditure can benefit by adjusting their expenditure patterns to take
account of changing relative prices by substituting goods that have become
relatively cheaper, for goods that have become relatively dearer.
The use or preference for particular goods may also change.
In the long run, the various PPIs, WPIs and the CPI
show a similar rate of inflation. In the short run PPIs often increase before
the WPI and CPI. Investors generally follow the CPI more than the PPIs. In
India WPI is used instead of CPI.

What is Core Inflation : The concept is used to
estimate the inflation by excluding food and energy prices from the basket of
goods and services that represents a typical household's
consumption. In mid 2012, RBI Governor threw up the conundrum posed
by this "Core"inflation by saying "In our economy, where food
constitutes nearly 50% of consumption basket and fuel has a weight of 15%, can
a measure of inflation that excludes them can be called
"Core". He suggested that India should move towards developing
and using a Producer Price Index (PPI) to gauge inflation more accurately as
wholesale price index does not capture the price movement of services and is a
hybrid of consumer and producer price quotes.
