National Income Accounting is one of the most basic
concept of the macroeconomics. Many people face difficulty while understanding
GDP, GNP, NDP, NNP, NNP(factor cost) etcetra.. beacause these are the basic
variables of macroeconomics a clear understanding and distinction among them is
necessary.
First of all let us contemplate what is National
income accounting? What is the need the calculate these variables? Do every
countries use these variables only for estimating their national income? We
will also come to the concept of a slightly different and unique variable used
by Bhutan.
So going one by one , let’s first explain National
income accounting ( NIA) . NIA is nothing
but the accounting of the national income. In commerce and finance we have studied
about accounting. Accounting means “ lekha Jokha”. i.e. the ledger book which
keeps the whole account of the income. Accounting is done on every level
ranging from household to industry. The same thing is done for the national
income too.
So various variables to assess the national income
of a country are:-
(1)
Gross Domestic Product( GDP)- It is defined
as the value of all final goods and services produced inside the territory
of a country within a specified period of time ( say an year).
Here
the key words are underlined.
The
two group of words are really important and we need to understand it minutely. The
first group mentions “final goods” what does it mean? It means only those goods
will be counted which are the final output. The intermediate goods will not be
counted. This is done to avoid double counting of the same good. Suppose that
while manufacturing a car its various parts like engine, tyre etc. are
considered and at the same time the final produced car is considered( which already
contains all these parts like engine , tyre etc.) , it lead to repetition of
the same good while calculating the value. This is why only final goods are
considered not the intermediate goods. This is to be kept in mind.
The
second underlined group of words is inside the territory of a country. It means
only those goods which are manufactured
within the boundary of the country will be considered. Eg. Tata has acquired
Jaguar. Tata is an Indian automobile manufacturing company while the production
facility of Jaguar is in UK. So the Car manufactured by the Tata Jaguar at UK
plant will not be considered while calculating the GDP of India. Similarly if
an American company or Korean company manufacture their product ( take the case
of cheap Samsung handset) , that will be considered while calculating GDP of
the country, because the product manufactured is within the Indian Territory.
(2)
Gross National Product (GNP)-
Here the key word is National. In this case
the goods and services produced by every national will be considered, whether
he is living in India or outside the country. At the same time value of goods
and services produced by foreigners in India will be excluded. Earlier a few
countries like USA used GNP as the indicator of their national income , but now
they have shifted to the GDP.
(3)
Net Domestic Product ( NDP)-
With time
the capital goods depreciate. It means that the value of the capital goods(
means of production, machinery, building etc.) reduces with time. So after
deducting this reduction from the GDP , a new variable defined is called the
NDP.
(4)
Net National Product ( NNP)-
This is
obtained by deducting depreciation from the GNP.
India
and most of the countries as well as
financial institutions like World Bank and IMF considers GDP as the variable
for calculating the national income of the countries. The comparison of well- being of an economy is done on the
basis of the GDP only. Current the GDP of India is 1.8 trillion dollar which is
1/5th that of China and 1/10th that of USA. This shows
that we are lagging too behind as compared to these countries in terms of
economic growth. In the next blog I will come with the concept of the GDP at
factor cost and market price as well as GDP at constant price and current
price. I will also discuss about the concept of the GDP Deflator and what is unique with the national income accounting
of Bhutan?.
