Macro Economics Macroeconomics is a branch of economics field that
studies how the aggregate economy behaves. In macroeconomics, a variety of economy-wide
phenomena is thoroughly examined such as, inflation, price levels, rate of growth, national income, gross domestic product and changes in unemployment
Useful to estimate National Income and Per Capita Income

National Income (N.I.) 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
Economy is in equilibrium when income = output = expenditure

National Income (N.I.) Household
Owners of Factors of Production Receive Income by supplying Services of Factors to
Firms Firms
Businesses who decide what, where, how and for whom to produce to goods and services
Receive Income by selling their output to household

Aspects of Circular Flow of N.I.
Real Flow Money Flow Movement of Factor
services from household to firms
Movement of Goods & Services from firms to Households
Movement of money as payment for factor services from firms to households
Movement of money as payment for goods & services from household to firms

Circular Flow of N.I. Closed Economy
Two Sector Economy (Without Savings) Two Sector Economy (With Savings)
Three Sector Economy Four Sector Economy / Open Economy

Closed Economy – Without Savings
Assumptions 2 Sectors only – Household and Firms Household owns Factors of Production Household receives payment for service of factors of
production Production Activities take place in Firms Only Both Household and Firms have ZERO Savings No Govt Operations or International Trade

Closed Economy – Without Savings

Closed Economy – With Savings Assumptions
2 Sectors only – Household and Firms Household owns Factors of Production Household receives payment for service of factors of
production Production Activities take place in Firms Only No Govt Operations or International Trade

Closed Economy – With Savings

Closed Economy – With Savings Savings are leakage from the circular flow of economy Households save a part of their income in form of Bank
Deposits or financial investments etc. Firms borrow money from banks or financial institutions
thus converting household savings into real investments Thus savings is injected back in economy in the form of
investment When savings are made circular flow of income is
disturbed due to leakage but is restored as real investments are made on account of injection

Three Sector Model (Firms, Household & Govt)
![Page 14: 1. circular flow of income](https://reader035.fdocuments.net/reader035/viewer/2022062412/5871f8691a28ab5c348b6feb/html5/thumbnails/14.jpg)
Four Sector Model (Firms, Household, Govt & External Sector)
![Page 15: 1. circular flow of income](https://reader035.fdocuments.net/reader035/viewer/2022062412/5871f8691a28ab5c348b6feb/html5/thumbnails/15.jpg)
Four Sector Model (Firms, Household, Govt & External Sector)
Savings, Taxes, Imports are leakages and Investment, Govt expenditure and exports are injections
Circular Flow of Economic Activities among 4 sector shows that there will be equilibrium in all sectors when
Savings = Investments Govt Expenditure = Taxes Exports = Imports

Four Sector Model (Firms, Household, Govt & External Sector)
To measure Circular Flow in various economies there are various stages as follows
Production Stage – Measured by Value of Output Income Stage – Measured by Earned Factor
Income Spending Stage – Measured by Extent of total
expenditure

Importance of Circular Flow of Income
Gives Clear Picture of Economy Smooth Functioning of Economy Guidance in Restoration of Equilibrium Helps to Find Leakages Highlights importance of Policies (Fiscal &
Monetary Policies for equality in income & expenditure)
