1.1 NATIONAL INCOME ACCOUNTING  
National Income Accounting, pioneered by the Nobel prize-winning economists Simon 
Kuznets and Richard Stone, is the system of macro-economic accounts from the stage of 
production of goods and services to the stage of their final disposal. Like any other accounting 
system , the national income accounts  first define concepts and then construct measures 
corresponding to these concepts . National Accounts help us to understand how the various 
transactions from the stage of production of goods and services to the stage of their final 
disposal are interrelated and give us an idea of the working of an economy. It helps to meet 
the needs of Government, private analysts, policy makers and decision takers.  
The Central Statistical Organisation (CSO) in the Ministry of Statistics and Programme 
Implementation (MoSP&I) is responsible for the compilation of National accounts statistics. 
At the State level, State Directorates of Economics and Statistics (DESs) have the responsibility 
of compiling their State Domestic Product and other aggregates.   
1.2 USEFULNESS AND SIGNIFICANCE OF NATIONAL 
INCOME ESTIMATES 
National income accounts are fundamental aggregate statistics in macroeconomic analysis 
and are extremely useful, especially for the emerging and transition economies.

DETERMINATION OF NATIONAL INCOME 
? The estimates of national income show the composition and structure of national 
income in terms of different sectors of the economy, the periodical variations in them 
and the broad sectoral shifts in an economy over time. 
? Sectoral contribution to National Income information is used by  the government to 
decide various sector-specific development policies to increase growth rates. 
? National income statistics also provide a quantitative basis for macroeconomic 
modelling and analysis, for assessing and choosing economic policies and for objective 
statements as well as evaluation of governments’ economic policies.  
? National income estimates throw light on income distribution and the possible 
inequality in the distribution among different income categories . It facilitates the 
process of comparisons of structural statistics, such as ratios of investment to growth 
, taxes proceeds and fiscal deficit , or government expenditures to GDP.  
? International comparisons in respect of incomes and living standards assist in 
determining eligibility for loans, and/or other funds or conditions under which such 
loans, and/ or funds are made available.   
? Combined with financial and monetary data, national income data provides a guide to 
make policies for growth and inflation.  
1.3 DIFFERENT CONCEPTS OF NATIONAL INCOME  
 We begin our discussion with the basic measure of output -Gross Domestic Product, 
or GDP. The production side of the economy transforms inputs, such as labour and 
capital, into output, GDP. Inputs such as labour and capital are called factors of 
production, and the payments made to factors, such as wages and interest payments, 
are called factor payments.                       
1.3.1 Gross Domestic Product  
Nominal GDP or GDPMP  
Gross domestic product (GDP) is the value of all final goods and services produced in the 
country within a given period. It includes the value of goods produced, such as houses and 
mobiles, and the value of services, such as telecom, health, insurance. The output of each of 
these is valued at its market price, and the values are added together to get GDP MP  
Nominal GDP or GDP at Current Prices in Q1 2022-23 is estimated at ? 64.95 lakh crore, as 
against ? 51.27 lakh crore in Q1 2021-22, showing a growth of 26.7 percent as compared to 
32.4 percent in Q1 2021-22

Real GDP  
Nominal GDP increases over time for two reasons: 
1. The production of most of goods increases over time  
2. The prices of most goods also increase over time.  
If our goal is to measure production and its change over time, we need to eliminate the effect 
of increasing prices on our measure of GDP. That’s why real GDP is constructed as the sum of 
the quantities of final goods times constant (rather than current prices)  
Real GDP or Gross Domestic Product (GDP) at Constant (2011-12) Prices in Q1 2022-23 
is estimated to attain a level of ? 36.85 lakh cror e, as against ? 32.46 lakh crore in Q1

DETERMINATION OF NATIONAL INCOME 
The GDP deflator, as the name implies, can be used to ‘deflate’ or take inflation out of GDP. 
In other words, the GDP deflator is a price index used to convert nominal GDP to real GDP 
Real GDP = 
Nominal GDP
GDP Deflator
 x 100 
The deflator measures the current level of prices relative to the level of prices in the base year. 
Since nominal GDP and real GDP must be the same in the base year, the deflator for the base 
year is always 100.  
As you know, inflation is a closely monitored aspect of macroeconomic performance and a 
significant variable guiding macroeconomic policy.  Using the GDP deflator, the inflation rate 
between two consecutive years can be compute using the following procedure: 
Inflation rate in year 2 = 
GDP deflator in year 2 -GDP deflator in year 1 
GDP deflator in year 1 
x 100 
GDP Deflator in India is expected to reach 154.87 points by the end of 2022, according to 
Trading Economics global macro models and analysts expectations. In the long-term, the India 
GDP Deflator is projected to trend around 167.94 points in 2023 and 175.67 points in 2024, 
according to  econometric models. 
Inflation Rate in 2023 = (167.94 - 154.87) / 154.87 * 100  
Inflation Rate in 2023 as compared to 2022 will be 8.439 percent.

SOLUTION 
A deflator above 100 is an indication of price levels being higher as compared to the base 
year. From years 2015 through 2019, we find that price levels are higher than that of the base 
year, the highest being in the year 2016.If the GDP deflator is greater than 100, then nominal
