Micro Economics

Unit 1

Introduction

Marks 4

Basic concepts of the lesson

Economics : Economics is a social science. It is concerned with the study of individual and

social choice in situations of scarcity.

Economy : Economy is the sum total of all economic activities.

Economizing Resources : Economizing resources means making best possible use of available

resources.

The need for economizing resources arises due to scarcity of resources.

Economic Problem : The problem of choice making is called economic problem.

Main causes for the emergence of economic problem are :

a) Unlimited wantsb) Limited resourcesc) Alternatives uses of resources

Central problem of an economy : Central problems arise due to scarcity of resources in

relation to demand for them.

Three Central problems of an economy are :

a) What to produce ?b) How to produce ?c) For whom to produce ?These three problem are generally grouped under one head Allocation of Resources

Production possibility Curve : It is a curve which shows various alternative production

possibilities of two goods with given resources and techniques of production.

Assumption of PPC :


5/52

1. Only two goods are produced2. All resources are fully employed3. No charge in technology

Characteristics of PPC

1. It is downward shopping from left tonight2. It is concave to the origin.

Opportunity Cost : Is in the value of next best activity. OR the cost of foreone alternatives.

Branches of Econimics :

1. Micro Economics2. Macro Economics

(The terms micro and macro were first used by Prof. Ragner Frisch in 1933)

Microeconomics deals with small parts of the economy.

Macroeconomics deals with the functioning of economics system as a whole.

Positive and Normative Economics :

Positive economics deals with what is or how an economic problem facing a society is

actually solved.

Normative economics deals with what ought to be or how an economic facing a society

should be solved.

Market economy and planned economy.

Market economy is a political economic system based on private property and private

ownership

Planned economy is controlled economy which is run by central authority with the motive of

promoting public welfare. VERY SHORT ANSWER TYPE

Short answer Type Questions (3/4 marks)

Q. 1 : distinguish between microeconomics and maroeconomics.

Ans

Micro economics Macro economics

1) The word micro is derived from the

greek work MIKROS which means

small.

2) It studies the behavior of individual

units of the economy.

3) It is alsobe called the price theory

4) It deals with the problem of

allocation of resources.

1) The word macro is derived from the

greek work MAKROSwhich means

large.

2) It studies the economy as a whole.

3) It is known as the income and

employment theory.

4) It deals with the problem of fuller

utilization of resources.

Q. 2 : What is an economic problem ? How does it arise ?

Ans : An economicproblem is basically the problem of choice which arises because of scarcity

of resources. Human wants are unlimited but resource to satisfy them are limited. In such a

situation, every individual and society have to make a choice as to which wants should be

satisfied by making use of scarce resources which have alternative uses. Thus, economic

problem is basically a problem of choice.

Q. 3 : What is production possibility curve? Draw a production possibility curve and show the

following situations ?

i) Fulles utilization of resources.

ii) Under utilization of resources.

iii) growth of resources.

Q. 5 : Explain briefly the central problems of an economy.


11/52

Ans (a) What to produce An economy has millions of commodities to produce but it cannot

produce all of them because of shortage of resources. Therefore it has to decide whether to

produce capital goods or consumer goods or it may have to decide whether to produce capital

goods or consumer goods or to may have to decide whether to produce luxury goods or

common goods and so on and at the same time quantity has also to be decided.

(b) How to produce The problem of how to produce means what technique of productionshould be employed to produce a good. Labour intensive and capital intensive technique are

the two techniques of production. In labour intensive technique more labour and less capital is

used, while in capital intensive technique more capital and less labour is used. The problem is

to decide which technique should be used

(c) For whom to produce For whom to produce is the problem of distribution of the goods

and services produced. What goods should be consumed and by whom depends upon how

national income is distributed among people/factor-owners.

Q. 6 : Distinguish between positive economics and normative economics ?

Ans :

Positive economics Normative economics

1. It deals with what is or how aneconomic problem facing a

society is actually solved.

2. It is based on cause and effectof facts.

3. It deals with actual or realisticsituation.

4. It can be verified with actualdata

1. It deals with what ought to beor how an economic problem

should be solved.

2. It is based on ethics3. It deals with idealistic situation4. It cannot be verified with actual

data.

Q. 7 : Distinguish between planned economy and market economy ?

Ans :

Planned Economy Market Economy

1. A economy which is controlledby central authority with the

objective of achieving definite

targets.

2. Main objective of such aneconomy is to maximize welfare

public.

3. Planned economy is madeoperative by some centralauthority who makes different

projects and plans for the

development of an economy.

Higher order thinking (Hots) Question

Q. 1 : Why economic problem of power shortage arise in India ?

A. Because demand for electric power in greater than its supply.

A. 2 : Is software industry a microeconomic study ?

A. Yes, because it is a study of an individual industry.

Q. 3 : How production possibility curve is affected When there is improvement in technique of

protection of a good ?

A. When there is an improvement is technique of production of one commodity, we can

produce Its more quantity with the given resources by which PPC rotates towards right. It

means production of another good whose technique of production remains constant, will

remain unchanged. As shown in the adjoining diagram we can produce BB1 additional quantity

of X good with an improvement in its technique.

Unit II

Consumer Equilibrium And demand

Marks 18

Basic concepts of the lesson.

Utility : Want satisfying capacity of the commodity is called utility.

Utility has two concepts

(1) Total utility :- It means the total satisfaction derived from consumption of given amount of

a particular good.

Or

TU is the sum total of MU i.e. TU = MU

(2) Marginal utility : It is the addition made to total utility from the consumption of additional

unit of the commodity.

MU = TUn - TUn 1

Consumer equilibrium : Consumer equilibrium is a situation when a consumer gets maximum

satisfaction from his consumption and he has no tendency to change. Condition of consumer

equilibrium.

(a) When he uses single commodity - xoficeRupeeaofMU

Law of diminishing marginal utility :

The Law of diminishing marginal utility states that as consumer consumes more and more

units of a commodity, marginal utility derived from successive units/additional units Goes on

falling.

Indifference curve : It is a locus of different combinations of two goods that yield equal

satisfaction to the consumer on all the points.

Properties of indifference curve :

I. IC is convex to the originII. It slopes downwords from left to right.III. Two indifference curves never intersects each otherIV. Higher indifference curve gives higher satisfaction.


14/52

Indifference map : Combination of two or more indifference curves is called indifference map.

Demand : Demand means the quality of a commodity which a consumer is willing to purchase

at a given price in a given period of time.

Individual demand and market demand : The quantity of a commodity that on individual

demands at a particular price in a given period of time in known as individual demand.

On the other hand the total quantity of commodity that all the consumers buy at a

particular price in a given period of time is called market demand

Demand Schedule : Tabular statement showing different quantities of a commodity demanded

at different prices is called demand schedule..

Demand curve : Graphical representation of demand schedule is called demand curve.

Demand function : Functional relationship between demand for a commodity and its

determinants is called demand function.

I. Percentage methodII. Total expenditure methodIII. Geometric method

Very Short Answer Type Questions (1 Marks)

Q. 1 : What is TU When MU in Zero ?

A. TU is maximum

Q. 2 : What is budget line

A. A budget line consists of all bundles which cost exactly equal to the consumers income.

Q. 3 : What is budget set ?

A. Budget set is the collection of all bundles that the consumer can buy with her income at the

prevailing market prices.

Q. 4 : Define substitute goods.

A : Goods which can be used in place of each other are called substitute goods. Ex. Tea &Coffee.

Q. 5 : What do you mean by complementary goods.

A. Goods which can be used together are called complementary goods. Example : Car & petrol.

Q. 6 : What is normal good ?

A. Goods whose income effect is positive are called normal goods.

Q. 7 : Define inferior goods.

A. Goods whose income effect in negative are known as inferior goods

Q. 8 : What is elastic demand ?


16/52

A. When percentage change in quantity demanded in greater than percentage change in price,

it is called elastic demand.

Q. 9 : If two demand curves intersect each other, which will have more elasticity ?

A. The flatter curve will be more elastic.

Q. 10 : Define contraction of demand.

A. Other things remaining the same with rise in price fall in demand is known as contraction of

demand.

Short answer type question (3/4 marks)

Q. 1 : Explain relationship between TV & MV.

A (1) Total utility increases till marginal utility is above zero.

(2) T. U is maximum when MU is zero

(3) T.U declines when MU becomes negative.

Q. 2 : Explain consumers equilibrium with the help of indifference curve technique.

A. According to indifference curve approach a consumer will be in equilibrium when the

following two condition are fulfilled :

(1) Budget line should be tangent to indifference curve i.e.

Q. 3 : Why demand curve slopes downward from left to right ? Or

Why does law of demand operates ;

A. Demand curve moves downwards from left to right because of the following.

1. Law of diminishing marginal utility

2. Income effect

3. substitution effect

Q. 4 : Distinguish between change in demand and change in quantity demanded.

A. Change in demand refers to the shift of demand curve due to change in other factors priceremaining the same.

When demand curve shifts right hand side it is called increase in demand and when

demand curve shifts left hand side it is called decrease in demand.

Change in Quantity demanded refers to movement along a given demand curve due to change

in price alone other factors remaining the same.

When movement is downwards it is termed as expansion of demand and when

movement is upwards it is called contraction of demand

Q. 5 : What causes rightward shift of demand curve ?

A. Demand curve shifts to RHS when there is increase in demand due to :

(1) Increase in income of the counsumer.

(2) Favourable change in Taste and preference of the consumer.

(3) Increase in price of substitute goods.

Q. 6 : State factors affecting market demand.

A. Factors affecting market demand are :

1. Price of the commodity

2. Price of related commodities

3. Income of consumers

4. Taste and preference of consumer

5. Number of household in the market

6. Distribution of income.

Q. 7 : State assumptions of the law of demand.

A. (1) There should be no change in the income of the consumer.

2. Tastes and preferences of the consumer should remain constant.

3. Prices of related goods should not change.

4. Consumers do not expect any change in price in future.

Q. 8 : Explain percentage method of measuring elastic of demand.

A. According to this method elasticity of demand is measured by taking ratio of percentage

change in quantity demanded to percentage change in price of the commodity

Ed = % change in quantity demanded/ % change in price

Example : When due price of a good falls by 10 % its quantity demanded rises from 40 units to

50 units calculate price elasticity of demand.

Solution : ed = % change in Quantity demanded/ % change in price.

Q. 9 : Explain total expenditure method of measuring elasticity of demand.


19/52

A. According to this method elasticity of demand is measured by comparing total expenditure

on the commodity before and after the change in price. It in estimated as follows:

1. If fall in price leads to increase in total expenditure and vice-vevra, Ed > 1

2. If fall in price reduces total expenditure and vice versa, Ed < 1

3. If fall or rise in price has no effect on total expenditure, Ed = 1

(2) Price of other commodities : The prices of related goods also affect the market demand for

a commodity. In case of substitute goods, demand for a commodity falls with a fall in price of

other commodity. In case of complementary goods demand for a commodity rises with a fall in

the price of other commodities.

(3) Taste and preference : Taste and preferences of the consumes also affect the market

demand for a commodity. If a consumers has developed a taste (a liking) for the commodity,the demand will increase and if he has no taste or preference for a product, the demand will

increase.

Q. 4 : Explain with the help of diagrams the effect of the following changes on the demand of a

commodity :

(1) A fall in the price of substitute good.

(2) A favourable change in the taste of the buyer.

And (i) The demand of a commodity and price of its substitute goods are directly related to

each other. When the price of substitute good falls, its demand rises and the demand of the

commodity falls and as a result the demand curve of the commodity shifts to the left. The

diagram shows the effect. In the diagram DD is demand curve of X (tea). With fall in price of

substitute good coffee demand for tea falls from OQ to OQ, at the same price OP. The demand

Q. 5 : Distinguish between an inferior good and. A normal good. Explain the effect of change in

income on each giving suitable examples.

A. Those goods which have direct price demand relationship or inverse income demand

relationship are known as inferior goods. For example in case of the price of unripened

bananas falls real income of the consumer increases. It induces him to buy less of unripened

bananas and buy more of good quality bananas.

Those goods which have inverse price- demand relationship or direct income demandrelation ship are known as normal goods. For example in case the price of milk falls, real

income of the consumer increases. Thus he is induced to demand more quantity of milk.

Q. 6 : Show the construction of individual and market demand schedule and curve when there

are two households in the market.

Ans. Construction of individual and market demand schedule and curve

Let there be two households A and B in the market for wheat. By aggregating or summing their

individual demands, market demand is obtained as shown in the table below :

Higher order thinking (HOT) questions.

Q. 1 : Define marginal rate of substitution.

A. It is defined as the amount of good Y the consumer is willing to give up to consume an

additional unit of good X while leaving total utility unchanged.

Q. 2 : What do you meant by monotomic preferences ?

A. A consumers preferences are monatomic if and only if between any two bundles, the

consumer prefers the bundle which has more of at least one of the goods and no less of the

other good as compared to the other bundle.

Q. 3 : When price of a good rises from Rs. 5 per unit to Rs. 6 per unit , its demand falls from 20units to 10 units. Compare expenditure on the good to determine whether demand is elastic

or inelastic.

Ans : Given

P = 5 Q = 20

P1 = 6 Q1 = 10

Initial expenditure = P x Q = 5 x 20

= Rs 100


26/52

Later expenditure = P1 x Q1 = 6 x 10

= Rs 60

As price rises from Rs 5 to Rs 6 per unit, expenditure falls from Rs 100 to Rs. 60 Price and

expenditure are moving opposite direction meaning that price elasticity of demand is elastic.

Q. 4 : At a given market price of good a consumer buys 120 units. When price falls by 50

percent he buts 150 units. Calculate price elasticity of demand.

Ans : Given, % fall in price = 50

Q = 120 units

Q1 = 150 units

Q = Q1 Q = 150 120 = 30 units

Q. 5 : What is the relation between good X and Good Y in each case if with fall in the price of X

demand for good Y (i) rises and (ii) falls ? give reason.

Ans (i) If with fall in price off X (say sugar) demand for good Y (say, tea) rises. Then goods X and

Y are complements.

(ii) If with fall in price of X (say tean) demand for good Y (say, coffee) falls, then X and Y are

substitutions.

Q.6 : Explain consumer equilibrium in case of two commodities.

Ans : When a consumer uses two goods he will be in equilibrium when he spends his income in

such a way that the ratio of the marginal utility of the two goods and their Prices is equal.

Q. 7 : Explain three main causes of downward sloping demand curve.

Ans : Following are three main causes responsible for the downward sloping nature of demand

curve.

1) Law of Diminishing Marginal Utility - The law of demand is based upon the law of

diminishing marginal utility. We know that marginal utility curve has a negative slope.

Therefore, the demand curve being based upon marginal utility curve being based upon

marginal utility curve also has a negative slope.

2) Income effect A change in the price of a commodity affects consumers real income. When

price falls, real income of the consumer increases This will induce him to buy more of this

commodity. This is called income effect.

3) Change in the Number of Consumers When the price of a commodity falls its consumption

spreads to more. & more consumers. Therefore, the number of its consumes expands and its

demand increases. Similarly when price increases, the commodity gets out of the reach of

some consumers. Hence its demand falls.

Q. 8 : What causes decreases indemand ?

A. (1) Fall in the income of the consumer.

(2) Fall in the price of substitute good

(3) Rise in the price of complementary good.

(4) Unfavorable change in the taste and preference of the consumer.

Q. 9 : A new steelplant comes up in jharkhand. People who were previously unemployed in the

area are now employed. How will this affect the demand for colour TV and Black & White TV in

the reason.

Ans : The demand for colour TV will increase and demand for Black & White TV will decrease.

Q10. Give the equation of budget line.

Ans: P1X1 + P2X2 = M

Q11. Explain why the budget line is downward sloping?

Ans: Budget line is downward sloping because if a consumer wants to buy more of one good,

he has to buy less of the other good, given money income

Q12. Suppose the price elasticity of demand for a good is -0.2. How will the expenditure on the

good be effected if there is 10% increase in the price of the good.

Ans: Given ed = -0.2. Since ed is less than one, it is a case of inelastic demand. If there is 10%

increase in the price of the good, there will be less than 10% fall in quantity demanded. Result

will be rise in expenditure.

MEASUREMENTOFNATIONALINCOME

1. There are three angles of looking at national income : (i) Value added, (ii) Income distribution and (iii) Final

expenditure.

2. Accordingly, there are three methods of measurement of national income namely (i) Value added method (ii)

Expenditure method.

3. Under all these methods, the first common step in the measurement of national income of a country is to classify its

producing enterprises into three industrial sectors : (i) Primary sector, (ii) Secondary sector and (iii) Expenditure

method.

4. Primary sector includes all units which produce goods and services by exploiting natural resources, agriculture,

forestry and logging. Fishing, mining and quarrying are its sub-sectors.

5. Secondary sector includes all those units which produce commodities by transferring one type of commodity into

another type of commodity. Manufacturing (registered and unregistered), construction, electricity, gas and water

supply, etc. are its sub-sectors.

6. Tertiary sector includes those units which produce services like educational, medical, transport, banking, insurance,

public administration and other services.

7. Value added method or production method is that method which measures the national income by estimating the

value added at factor cost by each producing unit in the domestic territory of the country in an accounting year

increased by the net factor income received from abroad. In this method, national income is measured at the

production stage.

8. The main steps involved in the measurement of national income by value added method are:

(i) Classify the producing enterprises into industrial sectors like primary, secondary and tertiary sectors.

(ii) Estimate the net value added at factor cost, (NVAFC) by each producing enterprise by taking the following sub-

steps :

(a) Estimate the value of output by adding sales and change in stock (closing stock opening stock).

(b) Estimate the value of intermediate consumption (i.e., cost of raw material) and deduct the same from

the value of output to arrive at gross value added at market price (GVAMP).

(c) Deduct Depreciation (D) and net indirect taxes (NIT) to the gross value added at market price to obtain

net value added at factor price. Symbolically,

NVAFC = Value of output IC D NIT.

(iii) Take the sum of net value added at factor cost by all the producing enterprises to arrive at net domestic product

at factor cost (NDPFC), i.e., NDPFC= NVAFC.

(iv) Add net factor income received from abroad to the Net Domestic Product at factor cost (NDPFC) to obtain Net

National Product at factor cost (NNPFC) which is the national income.

9. Precautions to be undertaken under value added method are :

(i) Avoid double counting of production. Instead of taking the value of output, take only the value added by each

production unit.

(ii) The output which is produced for self consumption and whose values can be estimated, must be included.

(iii) The sale and purchase of second hand goods should not be included in the current production because the value

of those goods has already been included earlier.

(iv) The value of services rendered in the sales (i.e., commission earned on account of sale and purchase of second

hand goods) must be counted because these services are freshly produced.

(v) The value of intermediate consumption is not included.


30/52

10. Income Method is that method which measures national income from the side of payments made in the form of

wages, rent, interest and profits to factors of production for their productive services in an accounting year increased

by the net factor received from abroad. In this method, national income is measured at the stage when factor

incomes are paid out by the producing enterprises to the factors of production.

11. The main steps involved in measuring national income through income method are :

(i) Classify the producing enterprises into industrial sectors like primary, secondary and tertiary.

(ii) Estimate the following factor income paid out by the production units in each sector :

(a) Compensation of employees (wages and salaries + employers contribution towards social security

schemes).

(b) Rent and Royalty, Interests and Profits.

(c) Mixed Income of self-employed units.

(iii) Take the sum of factor incomes by all the industrial sectors to arrive at the net domestic product at factor cost

(NDPFC) which is called domestic income.

(iv) Add net factor income from abroad to the net domestic product at factor cost to arrive at the net national

product at factor cost (NNPFC) which is the national income.

12. Precautions to be taken under income method are :

(i) While estimating compensation of employees, all benefits accruing to the employees whether in cash or in kind

must be included. It should not include only cash payments to the employees.

(ii) In estimating interest, the interests on only those loans should be included which are taken for production. The

interest on loans taken to meet consumption expenditure is a non-factor income and so it is not included in

national income.

(iii) Transfer incomes should not be included.

(iv) Gifts, donations, charities, taxes, fines, lotteries, etc., are not factor incomes. These should not be included in

estimating national income.

13. Expenditure Method is that method which measures the final expenditure on gross domestic product at market

price during an accounting year. This total final expenditure is equal to gross domestic product at market price. In this

method, national income is measured at the point of expenditure.

14. The main steps involved in measuring national income through expenditure method are as follows :

(i) Classify the economic units incurring final expenditure into distant groups like household, government, firms etc.

(ii) Estimate the following expenditure on final products by all economic units :

(a) Private final consumption expenditure (PFCE).

(b) Government final consumption expenditure (GFCE).

(c) Gross domestic capital formation (GDFC).

Gross domestic fixed capital formation. Change in stock = (Closing stock Opening stock).

(d) Exports Imports (X M).

The sum total of all the above expenditure on final products of all the sectors of the economy gives us gross domestic

product at market price (GDPMP).

(iii) Deduct depreciation (D), net indirect taxes (NIT) to the gross domestic product at market price to get net

domestic product at factor cost (NDPFC).

NDPFC = GDPMP D NIT.

(iv) Add net factor income from abroad (NFIA) to the net domestic product at factor cost (NDPFC) to obtain net

national product at factor cost (NNPFC) which is the national income.


31/52

NNPFC = NDPFC + NFIA = National Income.

15. Precautions to be undertaken under expenditure method are :

(i) Avoid double counting of expenditure by not including expenditure on intermediate products. Only the

expenditure on final products is included.

(ii) Expenditure on gifts, donations, taxes, scholarships, etc. is not expenditure on final products. These are transferexpenditures and should not be included in the final expenditure.

Expenditure on purchase of second hand goods should not be included as the expenditure on these has been

included when bought for the first time.

REALANDNOMINALNATIONALINCOME

Real National Income: It is defined as the value of current output at some base year prices.

Nominal National Income: It is defined as the value of current output at current year prices.

GNP Deflator = (Nominal GNP / Real GNP) * 100.

Green GNP is defined as the GNP which would help to attain a sustainable use of natural environment and

equitable distribution of benefits of development.

GDPANDWELFARE

GDP is not a precise Index of Welfare, because it ignores (i) distribution of income, (ii) composition of GDP, (iii)

non-monetary transactions, and (iv) the impact of (positive and negative) externalities.

Fiat Money refers to money by order/authority of the government. It includes notes and coins.

(ii) Non-legal Tender Money : It is optional and voluntary money which is generally accepted as money on the basis

of trust that their issues commends e.g., cheques, drafts, bills of exchange etc. It is also called Fiduciary Money.

Fiduciary Money refers to money backed up by trust between the payer and the payee.

II. Functional Definition : Money can be defined as anything that is generally accepted as a medium of exchange and at

the same time acts as a measure of value, store of value and standard of deferred payments.

III. Narrow vs. Broad Definition : Narrow definition of money is based upon its medium of exchange function, while in

Broad definition of money scope of money is extended to include store of value function in addition to medium of

exchange function.

CLASSIFICATIONOFMONEY

I. Full Bodied Money : It is money whose value as a commodity for non-monetary purposes is equal to its value as

money e.g., gold coins, silver coins etc.


35/52

II. Representative Full Bodied Money : It has no value as a commodity but it represents in circulation an amount of

money with a commodity value equal to the value of money e.g., paper money.

III. Credit Money : Credit Money is money whose value as money is more than the commodity value of the material

form in which the money is made e.g., token coins, representative token money, circulatory promissory notes issued

by the central bank and deposits at bank.

MONEYSUPPLY

Meaning : It refers to the stock of money held by the public at a point of time in an economy.

Measures of Money Supply :

M1=C + DD + OD

where

C = Currency held by public,

DD = Net demand deposits of the bank,

OD = Other Deposits held with the RBI

M2 = M1 + Savings of the people with post offices

M3 = M1 + Net time deposits with the commercial banks

M4 = M3 + Savings with the post offices (other than in the form of N.S.Cs)

M1 is the most liquid, narrow and least comprehensive measure.

M3 is the most commonly used measure of money supply.

M4 is the least broad and most comprehensive measure.

BANKING

Bank : Bank is defined as an institution which receives funds from the public and gives loans and advances to those who

need them.

Commercial Bank : It is an institution that accepts deposits from the general public and extends loans to household,

government and firms with a view to earn profit.

Functions of a commercial Bank :

I. Primary Functions

(i) Accepting deposits Fixed Deposits, Current Deposits, Savings deposits, Recurring Deposits etc.

(ii) Advancing loans Cash credit, Term/Demand loans, Overdraft, Discounting of Bills of Exchange etc.

1. Currency Authority2. Banker to the Government3. Bankers Bank and supervisor4. Lander of last resort5. Custodian of foreign exchange reserves6. Controller of money supply and credit7. Clearing house function


37/52

Difference between a Central Bank and a Commercial Bank :

1. The Central Bank is an apex bank while a Commercial Bank functions under the control of the Central Bank.2. A Central Bank is a government institution but a Commercial Bank may be a government or a private institution.3.

The Central Bank focuses on social welfare while a Commercial Bank focuses on profit maximization.

4. A Central Bank does not directly deals with the public while a Commercial Bank does.5. A Central Bank has a monopoly of note issue while a Commercial Bank does not have any such power.6. A Central Bank controls credit in a country while a Commercial Bank creates a credit.7. There is only one Central Bank in a country while Commercial Banks may be in any number.

Credit control by the Central Bank :

1. Quantitative measures :

(i) Bank rate It is the rate at which the Central Bank lends funds to banks against approved securities or eligible

bills of exchange. During inflation by increasing the bank rate, the flow of credit reduces and on the other hand

during deflation Central Bank reduces the bank rate to increase the flow of credit.

(ii) Open Market Operations It refers to the sale and the purchase of government securities in the open market by

the Central Bank. By selling the securities it withdraws cash balance from the economy and vice versa.

(iii) Cash Reserve Ratio It refers to the minimum percentage of net deposits of the banks which they are required

to keep the Central Bank. When the flow of credit is to be increased the CRR is reduced and vice versa.

(iv) Statutory Liquidity Ratio Every bank is required to maintain a fixed percentage of its assets in the form of cash

or other liquid assets, called SLR. For reducing the flow of credit the Central Bank increases the SLR and vice

versa.

2. Quantitative measures :

(i) Margin Requirement

(ii) Selective Credit Control

(iii) Moral Suasion

(iv) Direct Action

UNIT 8

DETERMINATION OF INCOME & EMPLOYMENT

Aggregate demand, aggregate supply and related concepts

Concepts of Aggregate demand :- AD refers to desired expenditure (planned expenditure)on the purchase of domestically produced good and services during an accounting year.

Components of AD:- 1. C (Private consumption expenditure) private consumption expenditure is determined

by the level of personal disposable income in the economy.

2. I (Private investment expenditure):- investment implies increase in the stock of capitalgoods it is market rate of interest which determine private investment expenditure.

3. G (Government expenditure):- It is include both consumption expenditure &investment expenditure of Government. It is autonomous investment.

4.X-M (Net Exports):- Exports importsAD= C+I+G+X-M

Or

AD=C+I

AD Schedule :- AD Schedule is a table showing combined behaviour of C and Icorresponding to different level of Y in the economy.

Concepts & component of AS:- AS refer to flow of goods and services as planned bythe producers during and an accounting year. Y=C+S

C and S are two component of AS AS line happens to be a 45o line this because of obvious identities between Y on the X-axis

and C+S on Y axis

Consumption function and propensity to consume:- Consumption function is the relationship between consumption and income C=f(Y) Fundamental psychological law :- 1. consumption expenditure increase with the increase income 2. minimum level of consumption incurred even when income (Y)=0 3. consumption does not increase at the rate at which income increase. Break even points Where C=Y Propensity to consume:- it refers to the schedule which shows the level of

consumption at different levels of income in an economy.

1. Average propensity to consume (APC):- it is the ratio of consumption expenditureto any particular level of income APC=C/Y

2. Marginal propensity to consume (MPC):- it is ratio of a change in consumption to achange in income MPC= C/ Y

Saving function and propensity to save : saving - it is the excess income over and above consumption during an accounting year

S=Y-C


39/52

E

Saving function refers to the relation between S and Y S=f(Y) Propensity to save :- a schedule showing amounts that will be saved at different levels of

income

1. Average propensity to save (APS):- it is ratio of saving to income APS =S/Y 2. Marginal propensity to save (MPS):- it is ratio of change in saving to a change in

income MPS=S/Y APC+APS =1 MPC+MPS=1 Concept Of Full Employment :- full employment is situation in which everyone who

wants to work is working except for those who are frictionally and structurally

unemployed.

Voluntary Unemployment :- It refer to the situation when a person unemployedbecause he is not willing to work at the existing wage rate, even when work is available.

Involuntary Unemployment :- it is situation in which people are able to work andwilling to work at existing rate of wages but do not get work.

Important Questions:1. Give Meaning of aggregate demand

2. Name the principal of component of aggregate demand.

3. What is aggregate supply ? What are its components?

4. Distinguish between average propensity to consume and marginal propensity to consume.

5. Distinguish between average propensity to save and marginal propensity to save. (tips-write definitions also)

6. What is consumption function? Illustrate its behaviour using a suitable diagram and table.

7. What is production function? Illustrate its behaviour using a suitable diagram and table.

8. Define following 1- Full employment 2- Voluntary unemployment 3- involuntary

unemployment 4- Break even point.Determination of Equilibrium Level Income and Employment

Equilibrium level of income is that level of income where aggregate demand equalsaggregate supply of output or (Level of planned saving equals planned investment.

AD = AS approach according to Keynes the equilibrium level of income and employmentis determined at a point where aggregate demand to is = to aggregate supply.

In the Figure AD and AS are interest at point E which indicate point of equilibrium where OM

is the equilibrium level of income = employment = output

a) if AD < AS- Stock of goods will start rising due to poor sales producers cut downemployment and output till AS = AD

b) if AD > AS there will be increase in income and productions. Effective Demand :- Aggregate demand at the point of equilibrium is called and effective

demand because it becomes effective in determination of national income and

Employments.

Planned Saving (ex-ante Saving) :- The saving which are planned to be made by allthe household in the economy during a period

Planned investment (Ex-ante investment) :- The investment which is planned ordesired to be made by the firms in the economy during the period.

Actual Saving (Ex-post Saving) :- it is the actual Amount of savings that took place,measured after the trade .

Actual investment (Ex-post investment):- it is the actual investment that took place,measured after the track.

Marginal efficiency of investment:- it refers to expected rate of return from marginalunit of investment .

There is inverse relationship between volume of investment and MEI


41/52

Multiplier and its Mechanism

The Concept of Multiplier

Investment multiplier or output multiplier refers to the factor by which output/incomeincreases, because of increase in investment. It is measured as the ratio between increases

in output/income and increases in investment. K=Y/ I Relationship between multiplier and MPC:-

There is the direct relationship between multiplier and MPC. Higher the value of MPC,

higher the multiplier and vice versa. K= 1/1-MPC = 1/MPS

Problems of Deficient Demand and Excess Demand

Deficient Demand :- Deficient demand is a situation when AD< AS (corresponding to fullemployment level).

Deflationary gap :- Deflationary gap is equal to the difference between AD-at fullemployment and AD-at underemployment.

Causes of Deflationary Gap:- (i) Reduction in private consumption expenditure, (ii)Reduction in investment expenditure (iii) reduction in government expenditure, (iv) Decline

in exports, (v) rise in imports, (vi) Increase in tax burden.

Consequences of deficient Demand causes Deflation underemployment:- when ADfails to catch up with As of full employment, all goods and services produced in the economy

cannot be sold Accordingly, profits start shrinking. This discourages investment and lowers of

income/employment in the economy. The economy is caught in a law level equilibrium trap

where low AD causes low output, and low output/income causes low AD.

Excess Demand:- Excess demand is a situation when AD> AS (corresponding to fullemployment level).

Inflationary Gap : Inflationary gap is equal to the difference between AD-beyond fullemployment and AD-at full employment.

Causes of Inflationary Gap:- Causes of inflationary gap are just opposite to the (abovestated) causes of deflationary gap. These related to a rise various components of AD, a rise

that continues to occur even when resources are fully utilized.

Consequences of Excess Demand Excess Demand causes inflation: Because excessdemand is that level of AD which surpasses AS (at full employment level0, It must cause

inflation. Output cannot be increased once full employment is reached Hence, AD beyond that

level would only cause pressure of demand on the existing supply, implying inflation. The

economy is caught in a wage-price spiral where wages catch prices and prices catch wages.

Combating Excess and Deficient Demand:- Measure of combating excess and deficientdemand, include: (i) fiscal measure, and (ii) monetary measure. Fiscal measure relate to

fiscal policy, and monetary measure related to monetary policy of the government.

Fiscal policy : It refers to the revenue and expending policy (or budgetary policy) of thegovernment to combat the situations of excess and deficient demand.

Components of fiscal policy and the way these are used :-(i) Government Expenditure: Increased to combat deficient demand, and decreased

to combat excess demand.

(ii) Taxes: Tax burden is lowered to combat deficient and raised to combat deficient

demand.(iii) Public Borrowing: Increased to combat excess demand, and decreased to combat

deficient demand.

Deficient Financing: Increases to combat deficient demand, and decreased to

combat excess demand.

Monetary policy: it refers to that policy of the government which combats excess

and deficient demand by regulating the cost of credit and availability of credit in the

economy.


43/52

Components of Monetary Policy and the way these are used:-

I. Bank rate: increased to combat excess demand, and decreased to combat deficientdemand.

II. Open Market Operations: The Central bank sells securities to combat excess demandand buys securities to combat deficient demand.

III. CRR: Raised to combat excess demand, and lowered to combat deficient demand.IV. SLR: Raised to combat excess demand, and lowered to combat deficient demand.V. Margin Requirement: Raised to combat excess demand, and lowered to combat

deficient demand.

VI. Moral Suasion: Banks are convinced and pressurized to pursue cheap money policy tocombat deficient demand, and dear money po0licy to combat excess demand.

VII. Rationing: Introduced to combat excess demand, and withdrawn (if already existing) tocombat deficient demand.

Important Questions1. What is Deficient Demand ?2. Define Deflationary gap.3. What is meant by Excess Demand?4. Define Inflationary gap.5. What is Fiscal Policy. How is it used to correct excess & deficient demand?6. What do you mean by Monetary Policy? How is it used to correct and Excess and Deficient

demand?

7. Explain Inflationary & Deflationary gap with the help of Diagram.

Government Budget and The Economy

Concepts of Govt. Budget Government Budget is the statement of estimates of thegovt. receipts and govt. expenditure during the period of the financial year.

Objectives of Government Budget(i) Redistribution of Income and Wealth(ii) Reallocation of Resources(iii) Economic Stability(iv) Managing Public Enterprises

Components of Budget(i) Budget Receipts Budget receipts refer to estimated money receipts of the

government from all sources during the fiscal year.

(ii)Budget Expenditures Budget expenditures refers to estimated expenditureof the government on its development and non development

programmes or on its plan and non plans programmes during

the fiscal year.

Components of Budget Receipts(i) Revenue Receipts Revenue receipts of the government are those money

receipts which do not either create a liability or lead to reduction

in assets.

Classification of Revenue Receipts

Tax Receipts A Tax is a compulsory payment made by an individual, household or afirm to the government without reference to anything in return.

Types of Taxes(i) Progressive and Regressive Taxes(ii) Ad Valorem and Specific Taxes(iii) Direct and Indirect Taxes

Direct Tax A Direct tax is really paid by the person on whom it is legally imposed. Eg:-Income Tax

Indirect Tax Indirect Tax is imposed on one person but paid by some other person.Eg:- Sales Tax

(ii) Capital Receipts Capital Receipts are those monetary receipts which

either create liability for the government or cause reduction in

the assets of the government.

Classification of Capital Receipts

Budget Expenditure Budget Expenditure refers to estimated expenditure of thegovernment on its development and non development programmes or on its plan and non

plan programmes during the fiscal year.

Components of Budget Expenditures(i) Revenue Expenditure- Revenue expenditure refers to estimated

expenditure of the government in a fiscal year which doesnt

either create assets or cause a reduction in liabilities. Eg-

Interest Payment, Expenditure of Subsidies, Expenditure on

defence.

(ii)Capital Expenditure - Capital expenditure refers to the estimatedexpenditure of the government in a fiscal year which either

creates assets or causes a reduction in liabilities. Eg.-

Expenditure of Land & Building, Machinery and equipments,

purchase of shares.

Development Expenditure It is directed towards development programmes of thecountry and which directly contributes to the flow of goods and services in the economy.

Eg.- Expenditure on the expansion of public sector enterprises.

Ca ital Recei ts

Recovery of Loans DisinvestmentBorrowings and other liabilities


46/52

Non Development Expenditure It is not directly related to development programmesof the country and which does not directly contributes to the flow of goods and services in

the economy. Eg.- Expenditure on defence.

Plan Expenditure It is incurred in accordance with planned development programmesof the country.

Non Plan Expenditure It is not incurred in accordance with planned developmentprogrammes of the country. Eg.- Expenditure as a relief to the earthquake victims.

Balanced Budget Total Expenditure = Total Receipts

Surplus Budget - Total Expenditure < Total Receipts

Deficit Budget - Total Expenditure > Total Receipts

Budget Deficit Budget Deficit refers to a situation when budget expenditures of thegovernment are greater than the budget receipts.

Three Types of Budget Deficit(i) Revenue Deficit - When Revenue Expenditure is more than the revenue

receipts.

Implications More people pay high taxation. Disinvestment and increase in the borrowings

of the government.

(ii) Fiscal Deficit - Fiscal deficit is in fact equal to the total borrowingsand other liabilities of the government.

Fiscal Deficit = Total or Budget Expenditure (Revenue Expenditure +

Capital Expenditure) Total or Budget Receipts other

borrowings (revenue receipts + capital receipts other than

borrowings).

Implications Greater Fiscal deficit implies greater borrowings by the government.

(i) Causes Inflation(ii) Increases Foreign Dependance(iii) Accumulates Financial Burden for future generation(iv) Multiplies Borrowings which causes Debt-trap.

(iii) Primary Deficit - Primary deficit is the difference between fiscal deficit

and interest payment.


47/52

Primary Deficit = Fiscal deficit Interest Payment

Measures to Contain Budgetary Deficits(i) Lowering Government Expenditures(ii) Raising Government Receipts through (a) Taxation (b) Disinvestment

Deficit Financing(i) Monetary Expansion - This amounts to printing of currency notes to the

extent of deficit.

(ii) Borrowings from the Public(iii) Disinvestment

National Income and

Related Aggregates

MEANINGOFMACROECONOMICS

1. Macro Economics is the study of aggregates or averages covering the entire economy such as national income, full

employment, unemployment, aggregate consumption, aggregate savings and general price level. In other words,

Macro Economics is the branch of Economics which is primarily concerned with the study of relationship between

broad economic averages. Macro Economics deals with the aggregates of the economy.

2. Lord J.M.Keynes, an eminent economist has played an important role in the development of macro Economics. He iscalled, The Father of Modern Macro Economics. He wrote a book on Macro Economics named General Theory of

Employment, Interest and Money published in 1936.

3. Macro Economics is alternatively called Theory of Income and Employment or simply income analysis. Under Macro

Economics, we try to explain how the level of income and employment are determined in an economy and how

unemployment can be removed.

4. The scope of Macro Economics includes the following topics :

(i) Concept and measurement of national income.

(ii) Determination of income and employment.

(iii) Money and Banking.

(iv) Government budget and the economy.

(v) Determination of foreign exchange rate and balance of payments.

CIRCULARFLOWOFINCOME

1. Circular flow of income forms the basis for measurement of Macro Economic activities. It helps to know the

functioning of an economy.

2. Circular flow of income refers to continual circular movement of money and goods in an economy.

3. Circular flow of income may be of two types : (i) Real flow and (ii) Money flow.

4. Under real flow of income, household render factor services to the firms and the firms produce goods and services to

pay further services.

5. Under money flow of income, all payments by the firms to the households for their factor services and by the

households to the firms for the purchase of goods and services are made in terms of money.

6. Flow of goods and services between firms and households is real flow and flow of money between the firms andhouseholds is money flow. If we prepare a diagram, we shall find that real flow is clockwise whereas money flow is

counterclockwise and vice-versa.

7. Circular flow of income is discussed under three different situations based on certain simplifying assumptions.

(i) Circular flow of income in a two sector company.

(ii) Circular flow of income in a three sector company.

(iii) Circular flow of income in a four sector company.

8. The circular flow of income in a two sector economy (or simple economy) is presented in the form of a figure given :

CONCEPTSOFNATIONALINCOME

1. National Income is used as a yardstick to measure the annual economic performance of the country.

2. National Income is defined as the sum total of factor income earned by the residents of a country during one year or

it is the sum total of market value of final goods and services produced by the residents of a country during one year.

3. Broadly speaking, there are eight concepts of aggregates of national income, viz., GDPMP, GNPMP, NDPMP, NNPMP,

GDPFC, GNPFC, NDPFC and NNPFC.

4. For a better understanding of these concepts or aggregates of national income, a knowledge of three fundamental

terms is essential.

(i) Depreciation (or Consumption of fixed capital).

(ii) Net Indirect Taxes, and

(iii) Net Factor Income from Abroad.

5. Depreciation (or consumption of fixed capital) refers to the loss of value of fixed assets due to its normal wear and

tear. This concept is used to make distinction between gross and net. If we deduct depreciation from gross, we get

net and if we add depreciation to net we get gross.

6. Net Indirect Tax (NET) is defined as the difference between indirect taxes (ID) and subsidies (S), i.e., NIT = IT S. This

concept is used to make distinction between market price and factor cost. If we deduct NIT from market price, we get

factor cost and if we add NIT to factor cost, we get market price.

7. Net Factor Income from Abroad (NFIA) is defined as the difference between factor income received from abroad andthe factor income paid abroad. This concept is used to make distinction between national and domestic. If we NFIA

from national, we get domestic and if we add NFIA to domestic, we get national.

8. GDP at market price refers to the total market value of all the final goods and services produced within the domestic

territory of a country in an accounting year, i.e., GDP = P*Q.

9. GNPMP = GDPMP + NFIA.

10. NDP = GDP Depreciation.

11. NNP = NDP + NFIA.

12. NNP = GNP Depreciation.

13. NDPMP = NNPMP NFIA.

14. GNPFC = GNPMP NIT.

15. NDPFC = NDPMP NIT.

16. Net National Product at factor cost is called National Income while the Net Domestic Product at factor cost is called

Domestic Income, i.e., NNPFC = National Income and NDPFC = Domestic Income.

17. Other related aggregates of national income are : (i) Income from domestic product occurring to private sector, (ii)

Private income, (iii) Personal income, (iv) Personal disposable income, (v) Gross national disposable income and (vi)

Net National disposable income.

18. Income from domestic product occurring to private sector = NDPFC Surplus of government sector. The main

components of surplus of govt. sector are : (i) Income from property and entrepreneurship accruing to government

administration departments and (ii) Savings of non-departmental undertakings of government.

19. Private Income is the income of the private sector. It is obtained by adding four terms : (i) Net Factor Income from

Abroad, (ii) Net current transfers from the rest of the world, (iii) Current transfers from government and (iv) Interest

on national debt to income from domestic product accruing to private sector.

20. Personal income is the income received by individuals or households of a country from all sources. This is obtained by

deducting two terms : (i) undistributed profits and (ii) corporate taxes from private income.

21. Personal Disposable Income refers to that part of personal income which is actually available to household for

consumption or saving. It is obtained by subtracting personal taxes and other miscellaneous receipts of government

(such as fines and penalties) from the personal income.

22. National Disposable Income (NDI) is the sum of all incomes received by the residents of a country which is available

for spending on consumption and for saving.

23. There are two measures of NDI : (i) Gross NDI and (ii) Net NDI.

24. Gross NDI is the sum of GNPMP and net current transfers from the rest of the world. Symbolically, Gross NDI = GNPMP

+ Net current transfers from the rest of the world.

25. Net NDI is the sum of NNPMP and net current transfers from the rest of the world. Symbolically, Net NDI = NNPMP +

Net current transfers from the rest of the world.

26. Gross National Income is another name for Gross National Product at factor cost (GNPFC). Alternatively, GNP = NI (or

NNPFC) + Depreciation.

27. Gross National Product is another name for Gross National Product at Market Price (GNPMP).
