Indian Economy / Macro Economic Aggregates
The main economic growth indicators for India are GDP (Gross Domestic Product), GNP (Gross National Product), NDP (Net Domestic Product) and NNP (Net National Product). Central Statistics Office (CSO) has taken 1950-51 as the base year for the first series of National Income estimates in India and subsequently changed it to 1960-61, 1970-71, 1980-81, 1993-94, 1999-2000, 2004-05 and 2011-12.
The most important indicator of economic growth for any country is GDP. A country's development is mainly measured with its GDP and the growth rate in its GDP. A country is said be progressing well when its GDP grows at a faster pace.
GDP is the aggregate of gross value added from all the final goods and services produced within the geographical boundaries of a country by the residents and institutions, irrespective of the nationality of the producer.
The basic concept in preparing the GDP is value addition which is also known as Income Generation.
Value Added = Value of the output - Value of the inputs.
The other approach to calculate GDP is expenditure method.
In this method, GDP = Consumption + Government Spending + Private Investment +
(Exports - Imports).
Gross National Product (GNP) is nothing but the total value of all the finished goods and services that are produced by a country's citizens and businesses in a given financial year, irrespective of their location whether thay are located inside or outside the country.
GNP = GDP + Net Value Added from abroad (or) Income from abroad (It is value added by Nationals only). Income from abroad includes the net remittances.
NDP = GDP - Depreciation or Consumption of Fixed Capital (CFC).
Note: Depreciation is also called Consumption of Fixed Capital.
NNP = GNP - Depreciation
NNP at factor cost is also called National Income (NI). It is used in calculation of per capita income.
If we take factors of production for calculating GDP, it will be called GDP at Factor Cost. The factors of production are Rent for the Land, Interest for Capital, Wages of Labour and Profit / Loss for Organization.
GDP at Market Price = GDP at Factor Cost + Indirect Taxes - The Subsidies
At Purchasing Power Parity, a US $ will have the same purchasing power in the US economy as well as in the domestic economy. GDP at PPP is equivalent to GDP/ Purchasing Power of $. India is third largest economy in terms of PPP. For calculating PPP, basket of goods is taken into consideration.
It is the GDP calculated at the Prices prevailing during the base year (2011-12). It is also called the Real GDP.
It is the GDP calculated at the Prices prevailing during the current year. It is also called the Nominal GDP. Growth rate is always measured in real term and not in the nominal term.
