Measuring Macroeconomic Activities
1. National Output(Q) or Income (Y) or Expenditure(E)
2. Price Levels(P) or Inflation ()
3. Unemployment (U) and Poverty
National Accounting(NA)
National Accountingis the method by which consistent estimates of
economic activity are produced.
1665: William Petty,English Economists, first introduced concept of
national income accounting.
1696: Georgory Kingimproved the Petty estimate by using three
separate ways of measuring domestic product(income,
production and expenditure).
1823: Joseph Lowe, a Scottish journalist and political economist,
used inflation figures to deflate national income.
1931: Simon Kuzentsattempted National Income Accounting for
US at NBER,Father of Modern National Income Accounting
1936: James Meade and Richard Stone creates National Income
and Expenditure for UK
1936: Wassily W. Leontief, developed Input out Analysis, an
interindustry relationship

All Output expresses with current and constant prices.
Output at Current Price is called Nominal Output
Output at Constant Price is called Real Output.
MP is what consumer pays
FC is what producer receives after
tax and subsidies

1.1.The Gross Domestic Product (GDP)
Gross Domestic Product(GDP) is the total market value of all final
goods and services produced within countrys borders irrespective of
ownership of resources during a given period of time (generally a year).
Ex. Phillips produces tube light with in India is GDP of India
TATA produces car in UK is GDP of UK but GNP of India.
GDP =piqi
Does not include:
Goods produced in the past Goods produced outside India by Indians Intermediate goods, Ex. Intel chips, wheat Non-market production
Black market: hawkers selling coconut
Underground economy: drugs, prostitution,
Household production: self consumption item, not sold in market

1.1.The Measurement of GDP (GDP)
GDP is the Market Value . . .
Output is valued at market prices.
. . . Of All. . .
Includes all items produced in the economy and legally sold in markets
. . . Final . . .
It records only the value of final goods, not intermediate goods (the value is
counted only once).
. . . Goods and Services . . .
It includes both tangible goods (food, clothing, cars) and intangible services
(haircuts, housecleaning, doctor visits).
. . . Produced . . .
It includes goods and services currently produced, not transactions involving
goods produced in the past.
. . . Within a Country . . .
It measures the value of production within the geographic confines of a country.
. . . In a Given Period of Time.
It measures the value of production that takes place within a specific interval of
time, usually a year or a quarter (three months).
1.1. GDP: ( GDPF and GDPM)
Govt. Intervention in Production: Yes or No
a. GDP at Market Prices(GDPM
): When the output of all final goods and services are
valued at market prices and the values thus obtained are added is known as GDPM. It
includes net of Indirect Taxes (Ti) and Subsidies (S)
b. GDP at Factor Costs/Prices(GDPF
):
Ex1. Let cigarettes: market price =Rs. 24
Let Indirect business tax = Rs. 4
so, GDP at market price = Rs. 24
GDP at factor cost = Rs.24 Rs.4
= Rs. 20
= total value-added
Ex.. 2: Education in an university
Lets total value-added in university =Rs.140
Out of which , subsidy = Rs. 20
School fee = Rs.120
So, GDP at market price = Rs. 120
GDP at factor cost = Rs120 + Rs.20 = Rs. 140
= total value-added
GDPF with Constant Price: Real GDP
GDPF with Current Price: Nominal GDP
GDPM
=GDPF
+ (Ti-S)
GDPF
=GDPM

1.2 GNP :Gross National Product (GNP):
Gross National Product(GNP) is the market value of all final goods and
services produced domestically irrespective of ownership plus net factor
income from aboard during a given year.
GNP= piqi +NFA
Net Factor Income from Abroad (NFAI) : Income received from abroad by the
normal residents of a country for rendering factor services minus income paid for
the factor services rendered by non-residents within the domestic territory.
a. Net compensation of employees(COE) ex. Visiting prof salary, compensation to Indian
people working at American Embassy in India, interest income received by Indianinvested in UK, or US Bonds, salary of Indian working at IMF, WB.
b. Net income from property and entrepreneurship ( interest, rent , profit and dividend)
Ex. Tata motors at UK, profits of SBI at London
c. Net retained earnings(undistributed profits) of residents companies abroad.
Ex Infosys at UK
GNP= GDP + Net Factor Income from Abroad
1.2 GNP : GNPM and GNPF
A) GNP at Market Price (GNPM
): When the output of all final goods and
services are valued at market prices (current price) and the values thus
obtained are added is known as GNPM.
It includes Indirect Taxes (Ti) and net of Subsidies (S)
GNPM
= GNPF
+Ti-S
B) GNP at Factor Cost (GNPF):
GNPF
= GNPM
Ti+S
For National Income identity purpose we use the following identity
GNPF C + I +G+X-M
Hence GNP GNI GNE

1.2. Net Product: NDP Vs NNP
Net Product (NP) Domestic or National : represents output ( income)after taking into account any future needs
It is calculated as total value of final goods and services
produced in the economy during a year minus depreciation.
NDPF=GDPF- depreciation
NDPM=GDPM- depreciation
NNPF=GNPF-depreciation
NNPM=GNPM-depreciation
NNPF is known asNational Income
1.4. How is GDP and GNP Related????
GNP=GDP+NetIncomefromabroad.
=>GDP=GNPGDP+NetIncomefromabroad
Similarly,
1. GNPF=GDPF+Netincomefromabroad
GNPM=GDPM+Netincomefromabroad

1.5 Private Sectors Income
a.Private Income: Income earned by households
Pvt.I = NNPF IAD END + NDI + TAD + OTA
b. Personal Income: Income received by households:
PI = Pvt.I RE CT
c. Personal Disposal Income: Income available for dispose
PDI = PI HDT MAD
IAD- Income from entrepreneurship and property accruing to govt
administrative deps ex. Railways
END- earnings of Govt. non departmental enterprises (PSUs)
NDI- National Debt Interest
TAD- Current Transfer from Govt. administration Dept.
OTA- Other net current transfer from abroad
RE- retained earnings of nations private corporate sector
CT- corporate tax
HDT- Household direct tax
MAD- Miscellaneous receipts of Govt. administrative dept. ex. Fines, fees

Problems and Solutions
Q. Mr. Moody, a barber works in his Saloon everyday . In one day he collectsRs.500 from haircuts, over this day his equipment's depreciates in value by
Rs.50. Of the remaining Rs.450, he pays sales tax worth Rs.30, takes home
Rs.200 and retains Rs.220 for improvement and buying of new equipment. He
further pays Rs.20 as income tax from his home. Based on this information,
estimate Mr Moody contributions to the following measures of income(a) GDP,
(b) NNP at MP,(c) NNP at FC, (d) Personnel Income, (e) Personnel Disposable
Income.Ans.
GDP=Rs. 500
NNPat MP= GDPDepreciation = 50050= Rs.450
NNP at FC=NNPSales Tax= 45030=Rs.420
PI= NNP at FCretained Earning= 420220= Rs.200
PDI= PIIncome Tax= 20020=Rs.180.
Mary spends on a final good, cosmetics, Rs.100
which is equivalent to its market value of Rs.100,
which is equivalent to the income to factor of
production Rs.100.
So for an economy as a whole during a given year,
Output Income Expenditure
because:
All output produced is for transaction purpose
Every transaction has a buyer and a seller.
Every rupee of spending by some buyer is a
rupee of income for some seller.

qi= Output of final good i
A. Primary
(i) Agriculture + (ii) forestry and Fishing + (iii) Mining and Quarrying
It is equal to the sum of the monetary value of all the final
goods and services produced within a country plus taxes
less subsidies on products.
The estimates of GDP in respect of agriculture, forestry, fishing, mining and
quarrying, registered manufacturing (establishments registered under
Factories Act, 1948) and construction are based on production approach

A. Pinky spends Rs.200 to buy her husband ice-
cream at a hotel in Gurgaon..
Consumption and GDP rise by Rs.200.
B. Sarah spends Rs.1800 on a new laptop to use in
her publishing business. The laptop was built in
China.
Investment rises by Rs.1800, net exports fallby Rs.1800, GDP is unchanged.
Answers
C. Jane spends Rs.1200 on a computer to use in her
editing business. She got last years model on
sale for a great price from a local manufacturer.
Current GDP and investment do not change,
because the computer was built last year.
D. Tata Motors builds Rs.500 million worth of cars,
but consumers only bought Rs.470 million of
them.
Consumption rises by Rs.470 million,
inventory investment rises by Rs.30 million,
and GDP rises by Rs.500 million.

C. Is GDP A Good Measure Of Economic Well-being?
Real GDP per capita is the main indicator of the average persons standard of living.
But GDP is not a perfect measure of well-being.
Some things that contribute to well-being are not included in GDP.
The value of Leisure
The value of a clean environment.
The value of almost all activity that takes place outside of markets, such as the
value of the time parents spend with their children and the value of volunteer
work.
GDP Measures the Size of the Pie but Not How the Pie Is Divided Up
Having a large GDP enables a country to afford better schools, a cleaner
environment, health care, etc.
Many indicatoRs.of the quality of life are positively correlated with GDP.
Then Why Do We Care About GDP?

IndexofIndustrialProductions
Represents the status of productions in industrial sector for a
given period of time
Sometime used as a proxy for measuring economic activities in
place of GDP.
Complied by Ministry of Commerce and Industry
IIP started compiling since 1937 covering 15 important
industries output comprising 90% of total productions
Since 1951, CSO is calculating IIP
Index is calculated by using simple arithmetic mean of
productions relatives calculated by Laspeyres formula: I=WiRi/Wi, Where I is the index, Ri is the productions relatives of the
ith item for the month in question and Wi is the weight alloted
to it
Weights are alloted on the basis of Gross Valued Added
Implications for Managers
Movement in national Income helps the manager to figure out the state of
the economy
Component of the national income helps to determine the production ,
distribution, demand structure etc. of the economy.
Expenditure pattern indicates the role of govt in economic activity
Role of govt enhances private competitions
Pattern of govt finances thorough direct and indirect axes affects the
disposable income of the households thereby their consumption pattern
Level of imports and exports provides information to the managers about
the demand pattern and the potential customers.in the international
markets
