National Income (N.I.) N.I. Means total income of a country expressed in terms of money N.I. Is the aggregate money value of goods and services produced
in a country during a particular year It is the money value of all economic activities of a nation in a given
year Products and services can be counted only once to measure the N.I. To avoid any double calculation only market value of final goods &
services are calculated (Defined in terms of Product Flow) Definition: “total market value of all final goods & services produced
in the economy during a given year”

National Income (N.I.) It can be viewed in various angles National Income = National Product = National
Expenditure National Income - all the incomes, in cash and kind
accruing to Factors of Production for generating the national product. It is National Income = National Product
National Product - Consists of all the goods and services produced and exchanged for money during a year. Does not include goods and services which are not paid for, such as hobbies, housewives’ services, charitable work, etc

National Income (N.I.)
National Expenditure – sum of consumers expenditure, net investment expenditure & govt’s expenditure towards final goods & services
One man’s income is another man’s expenditure
National Income = National Product = National Expenditure

Personal Income (P.I.) Total of all income received by an indi. from all his sources
in a given year P.I. = N.I. – (Social Security contributions + corporate Taxes
+ Undistributed Profits) + Transfer Payments Social Security contributions, corporate tax & undistributed
profit is not actually received by individuals hence deducted from N.I.
Transfer Payment like pension, unemployment compensation etc. is not earned by individuals but received by indi. hence added to N.I.

Disposable Income (D.I)
D.I. is the income available with a person to spend on consumption & savings
After accounting for direct personal tax like income tax, wealth tax etc, the remainder of personal income is known as Disposable income
DI = Personal Income – Personal Taxes DI = Consumption (C) + Savings (S)
![Page 8: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/8.jpg)
Per Capita Income (PCI)
It refers to the average income per head in the country
PCI = NI / P (Population) This concept is useful to know the average
std of living of people in a country

Real Income Real income is income of individuals after adjusting
for inflation The income of an individual or group after taking into
consideration the effects of inflation on purchasing power. For example, if you received a 2% salary rise over the
previous year and inflation for the year was 1%, then your real income only rose 1%. Conversely, if you received a 2% raise in salary and inflation stood at 3%, then your real income would have shrunk 1%

Gross National Product (GNP) GNP is the aggregate market value of all final goods &
services produced in a country during a year GNP in Open Economy = C + I + G + (X-M) + (R-P) GNP in Closed Economy = C + I + G C = Consumer Goods & Services I = Gross Investment including depreciation G = Govt Expenditure on Goods & Services X-M = Export – Import R-P = Net Foreign Income (Receipt – Payments)

Net National Product (NNP)
NNP is GNP less Depreciation i.e. NNP = GNP – Depreciation (D) Depreciation is the wear & tear of capital
assets that takes place during production process
![Page 13: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/13.jpg)
Gross Domestic Product (GDP)
GDP refers to the money value of good & services produced within the geographical boundaries of a country.
Income from abroad is NOT included GDP = GNP – Net Income from Abroad GDP = C + I + G + (X-M)
![Page 14: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/14.jpg)
Net Domestic Product (NDP)
NDP is obtained when depreciation cost is deducted from GDP
NDP = GDP – Depreciation (D)
![Page 15: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/15.jpg)
N.I. @ Mkt Price & Factor Cost N.I. @ Market Price (MP) Refers to money value of all goods & services produced
in an economy in a year at current mp. MP includes indirect taxes
N.I. @ Factor Cost (FC) Refers to aggregate of factor cost (rent, wages, interest
& profit) for producing goods & services. It can be calculated by deducting indirect taxes or adding subsidies to market prices
![Page 16: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/16.jpg)
N.I. @ Mkt Price & Factor Cost Scenario 1 MP of 1 Kg sugar is Rs.25 which includes Indirect tax
of Rs. 5 and cost of Production is Rs. 20 i.e. NI mp = Rs. 25 and NI fc = Rs. 20 Scenario 2 MP of 1 Kg sugar is Rs.25, cost of production is Rs.28
and subsidy given by govt is Rs. 3 i.e. NI mp = Rs. 25 and NI fc = Rs. 28
![Page 17: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/17.jpg)
NI @ Current Price & Constant Price
N.I. @ Current Refers to sum of net money value of all goods & services produced in
a country during a year. It is obtained by multiplying physical output of goods with current prices in that year
N.I. @ Constant Price It is the money value of final goods and services produced in a
country in a year, measured at base year price. Base Year is a normal year which is free from price fluctuations.
Presently 2004-2005 is taken as the base year in India. If we measure India’s National Income of 2013-2014 at the prices of 2004-2005, then it is termed as ‘National Income at constant price’
![Page 18: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/18.jpg)
Measurement of National Income
There are 3 methods of measuring N.I. Product/Value Added Method Census of Income Method Expenditure Method
![Page 19: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/19.jpg)
Product/Value Added Method Here, N.I. is measured as a flow of goods and services Money value of all final goods and services produced in an
economy during a year are calculated Final goods refer to those goods which are directly
consumed and not used in further production process. Goods which are further used in production process are called intermediate goods
In the value of final goods, value of intermediate goods is already included therefore value of intermediate goods is not included in national income otherwise there will be double counting
![Page 20: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/20.jpg)
Product/Value Added Method To avoid the problem of double counting we can use the value-
addition method in which not the whole value of a commodity but value-addition at each stage of production is calculated and these are summed up to arrive at GDP
Sectors which produce goods & services are broadly divided into 3 sectors – primary, secondary & tertiary
Each sector is further sub divided e.g. Primary sector – Agriculture, Fishing, mining etc. Secondary – Mftg – large & small scale etc. Tertiary – Transport, Communication, Trade etc.
![Page 21: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/21.jpg)
Product/Value Added Method Value of Gross Output produced by each
producing unit in a sub sector is obtained From Gross Value, value of Raw Materials,
Intermediate products and depreciation is deducted to get net value of output produced
By adding the net value of all producing units in all sectors we derive net value of the economy viz. Net Domestic Product (NDP)
![Page 22: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/22.jpg)
Product/Value Added Method
If NDP is at the market price then NDP at factor cost can be obtained by reducing indirect taxes and adding subsidies
By adding Net income from abroad (R-P) to NDP we derive Net National Product at factor cost which is National Income
![Page 23: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/23.jpg)
Product/Value Added Method N.I. with product/value added method can be
depicted as Y = (P-D) + (S-T) + (R-P) Y = National Income P = Domestic Output of all goods and services D = Depreciation S = Subsidies T = Indirect Taxes R – P = Receipts – Payments from Abroad
![Page 24: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/24.jpg)
Income Method Here N.I. Is obtained by adding all the factor income Factor Income includes rent, wages, interest and
profit Transfer Income is not included in National Income In case of self employed people, income may come
from various sources, hence concept of mixed income is used
N.I. = Rent + Wages + Interest + Profits
![Page 25: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/25.jpg)
Expenditure Method Income earned by factors of production is either spent or saved Expenditure is of 2 types – Consumption Goods or Capital Goods Expenditure done on final goods & services is only calculated to avoid
double counting Total Expenditure consists of consumption + capital investment
expenditure Both expenditure are incurred by private sector and government Private Consumption = Household expenses on consumption goods Govt Consumption = expenditure on education, health services etc.
![Page 26: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/26.jpg)
Expenditure Method Capital Investment is also incurred by private & govt Investment is of 3 types
Inventory Investment Net Fixed Investment Replacement Investment
Increase in stock of capital goods in economy is e.g. of inventory and net fixed investment
Wear & Tear of capital goods is represented by replacement investment
![Page 27: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/27.jpg)
Expenditure Method
All 3 investments together represent Gross Domestic Investment (GDI)
When we deduct replacement investment we derive Net Domestic Investment (NDI)
When Net Foreign Investment is added to GDI we get Gross National Investment
![Page 28: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/28.jpg)
Measurement of National Income
The 3 methods of calculating N.I. give us dimensions of economy
Product Method – Sectoral distribution of N.I. Income Method – Distribution of N.I. Among
various factors can be analyzed Expenditure Method – Level of Consumption &
investment Expenditure Output (Product) = Income = Expenditure
![Page 29: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/29.jpg)
Difficulties in Measuring N.I. Double Counting Service Included – what service to include & which to exclude Calculating Depreciation Illegal Activity Improvement in quality not considered New companies enter into the market Goods kept for self consumption No proper records as people are illiterate Various Economic Activities – Seasonal nature etc. No proper data is available

Real GNP v/s Nominal GNP
Measures the changes in the output of the economy according to the prices of base year i.e. GNP at constant prices
Central Statistical Organization (CSO) calculates the GNP at constant & current prices
Actual growth of Nat.Inc due to increase in output is indicated by real GNP
CSO considers year 2011-2012 as the base year for calculating real GNP
Measures GNP at current market price
Does NOT indicate real growth of N.I.
Changes in Nominal Income may be for 2 reasons
i) increase in Output Ii) increase in price
Real GNP Nominal GNP

National Income Deflator GDP Deflator is a measure of overall change in the prices
of the economy Deflator is useful to measure the changes in the overall
level of prices in goods & services that make up GDP GDP inflator is a price index that measures average level
of prices for specified set of goods & services in relation to the prices in a specified year
GDP Inflator = N.I. @ Nominal Price (Current Price) X 100 N.I. @ Constant Price(Real Income)
![Page 33: 2. national income](https://reader035.vdocument.in/reader035/viewer/2022070601/5882dad61a28ab33258b48e1/html5/thumbnails/33.jpg)
National Income Deflator
GDP Deflator in 2012 (Base Year) = 60,000 / 60,000 * 100 = 100%
GDP Deflator in 2015 (Current Year) = 66,000 / 62,000 * 100 = 106.5 %
i.e. Overall price is 6.5% higher in current year than base year
