INTRODUCTION
GIST OF THE LESSON
Meaning of economics: Economics is the science which studies human behavior as a relationship between ends and scarce means which have alternative uses.
Meaning of an economy:-Economy is the system which provides people the means to work and earn a living. Or it is a frame work within which economic activities like production, consumption, and capital formation are undertaken.
Meaning of scarcity:-It is defined as excess of demand over available supply, i.e, demand of resourses>supply of resources.
Economic problem:-The problem of making a choice is called economic problem.
Causes of economic problem:- It arises due to
1) Scarcity of resources 2) Unlimited human wants 3) Resources can be put to alternative uses
Scarcity and Choice go together:-Scarcity and choice are not separable because resources are limited or scarce and the problem of choice arises due to it.
Economising of resources:-Our wants are unlimited and resources are limited, so we have to use the resources fully and efficiently. It means that resources should be best utilized. This is called economizing of resources.
Central Problems of an Economy:-Central problem of an economy is Allocation of resources.The three central problems relating to allocation of resources are:-
1) What to produce:-The problem of what to produce and in what quantity is the
first basic or central problem. It is related to the selection of goods. Our resources are limited. So first problem that we have to face is which goods and services are to be produced e.g consumer goods or capital goods, war time or peace time goods. After the decision has been taken the quantities of these goods should also be decided.
2) How to produce:- The second important problem is the problem of choice of technique of production. That means we have to decide whether to use labour intensive technique(it uses more of labour than capital) or capital intensive technique(it uses more of capital than labour).How ever the choice of technique depends on the objective of the producer.The producer can use
labour intensive ,capital intensive or both technique of production.The main aim is to use the efficient technique of production.
3) For whom to produce:-This is also called the problem of distribution of National Income among the factor of production. For whom to produce is actually the problem of determining wage rate for the use of labour ,rent for the use of land, interest for the use of capital and profits for the producer to ensure equitable distribution of income and welfare in the society.
Production possibility curve or frontier
A production possibility curve/ frontier shows different combinations of two commodities that can be produced by an economy with the full use of given resources and technology.
(i)Normally, the production possibility curve is concave to the origin. It is because of increasing marginal opportunity cost.
(ii)A production possibility curve shifts out due to technological progress or increase in thesupply of resources available to an economy or both.
Assumptions of PPC-1)Resources are constant.
2)Technology is given. 3)Resources are fully and efficiently used. 4)Production of only two goods can be shown in a PPC.
Features of PPC-1) It is downward sloping.
2) It is concave to the origin.
PPC can be explained with the help of a schedule
.
Shifting/Rotation of PPC
a) Change of Resources
(ii) Change in technology
• Efficient technology for the production of Commodity – X: Efficient technology
for the production of Commodity – X would mean more production of commodity – X with the same resources. Accordingly, PPC would rotate (NOT SHIFT) as shown in Fig
Efficient technology for the production of Commodity – Y : Efficient technology for the production of commodity – Y would mean more production of Y with the same resources. Accordingly, PPC would rotate (NOT SHIFT) as shown in Fig
Efficient technology for the production of both X and Y:
Efficient technology for the production of both X and Y would mean much greater production of both X and Y with the same resources. Accordingly, PPC would shift to the right as shown in Fig.
Opportunity Cost (Transformation cost)-
The opportunity cost of a factor is equal to the value of a factor in its next best
alternative use. Eg-A plot of land can be used for wheat and rice production.Production of wheat provides earning of Rs. 1 lakh and Production of rice provides earning of Rs. 90000.If we produce wheat then its opportunity cost is Rs. 90000,which is the value of rice sacrificed.
Marginal opportunity cost(or Marginal Rate of Transformation)-
The marginal opportunity cost of good X is the rate of sacrifice of the other good, say, Y, per unit increase in the production of good X.
Or
The marginal opportunity cost of good X is defined as the amount / quantity sacrificed of good Y per unit increase in production of good X.
Marginal opportunity cost along a PPC.
Production of Good X
Production of
Good Y
Marginal Opportunity Cost of Good X in terms of Good Y or amount sacrificed of good Y per
unit increase in good X
0 18 - 1 17 1 2 15 2 3 12 3 4 8 4 5 3 5
Note: The above table shows the case of increasing marginal opportunity cost. To produce one more unit of Good X, increasing units of Good Y have to be sacrificed. For example, to produce the first, second, third, fourth and fifth unit of Good X, 1, 2,3,4 and 5 units of Good Y have been sacrificed respectively.
The shape of PPC depends on MOC :
1. If MOC is increasing PPC is concave.
2. If MOC is decreasing, PPC is convex.
3.If MOC is constant, PPC is a straight line.
The Fig Illustrates the concept of marginal opportunity cost. It is assumed that initially resources are employed such that, output in Use-1 = OK and output in Use- 2=OL
M.O.C = Loss of Output of Good Y/Gain of Output of Good X
= KK1 / LL1
= ab / bc= Slope of production possibility curve
Micro and Macro Economics:
Micro economics studies the behaviour of individual economic units of an economy like a consumer, a producer for different goods and services.
Macroeconomics studies aggregates at the level of the economy as a whole like
aggregate demand, aggregate supply, problem of full employment, total saving, total investment, aggregate price level, etc.

QUESTIONS FOR BRIGHT LEARNERS
VERY SHORT ANSWER TYPE QUESTIONS: - (1 Mark Each)
Q.1. Why is there a need for economizing of resources?
Ans. Because resources are limited.
Q.2. Why does economic problem arise?
Ans. It arises mainly because of scarcity of resources.
Q.3. Why is PPC downward sloping from left to right?
Ans. Because in situation of full employment of resources, production of one good can be increased only with less of other good.
Q.4. What does a rightward shift of PPC indicate?
Ans. The rightward shift of PPC indicates growth of resources or technological progress.
Q.5. Why does the problem of choice arise?
Ans. Relative scarcity of resources having alternative uses in relation to unlimited wants, gives rise to an economic problem.
Q.6. Why does PPC look concave to the origin?
Ans. PPC is concave to the origin because of increasing marginal rate of transformation (or increasing marginal opportunity cost).
Q.7. Which factor lead to a shift of PPC towards right hand side?
Ans. Growth of resources or technological progress leads to a shift of PPC towards right-hand side.
Q.8. What does a point below PPC indicate?
Ans. It shows inefficient/underutilization of resources.
Q.9. What is the slope of PPC? What does it show?
Ans. Slope of PPC refers to MRT (marginal rate of transformation).It shows that in order to produce more units of one good, say X, some units of the other good, say Y must be sacrificed. So slope of PPC= ∆Y/∆X
Q.10. When allocation of resources is considered as inefficient?
Ans. Allocation of resources is considered as inefficient when economy performs below the PPC curve.
Q.11.When can PPC be a straight line?
Ans. When MOC is constant.
Q.12 What is the opportunity cost of opting for higher studies rather than a job?
Ans.It is the amount of wage/salary the person would have earned in a job.

X
O Commodity X P P’ Ans. (a) Full employment of resources - A point anywhere on the PPC, shows the efficient use or full employment of resources.
(b) Underutilisation of resources - A point anywhere inside of the curve, shows inefficient/under utilisation of resources.
(c) Growth of resources – It refers to the shift in PPC. If more resources are generated, the level of production will increase. In the figure it is represented by a shift in PPC from PP to P‟P‟.
Q.2. Why does PPC look concave to the origin? Explain.
Ans. PPC looks concave to the origin because of increasing marginal rate of transformation/ substitution (or increasing marginal opportunity cost). It means that more and more units of commodity „y‟ are to be sacrificed, to get each additional unit of commodity „x‟.
Q.3. What does a PPC show? When will it shift to the right?
Ans. Production Possibility Curve shows the different combinations of two goods which an economy can produce with available technology and resources.
It would shift towards right-hand side in case of growth of resources or technological progress.
Q.4. Does production take place only on the PP curve?
Ans. Yes and no, both. Yes, if the given resources are fully and efficiently utilized. No, if the resources are underutilized or inefficiently utilized or both.

Refer to the above figure; on a point anywhere on the PPC the resources are fully and efficiently employed. On point U, below the PPC or any other point but below the PPC, the resources are either underutilized or inefficiently utilised or both. Any point below the PP curve thus highlights the problem of unemployment and inefficiency in the economy.
Q.5. Why does an economic problem arise? Explain.
Ans. Reasons-
1. Unlimited wants - Human wants go on multiplying with the expansion of education, knowledge, scientific advancement and economic growth. A man can not satisfy all of his wants and therefore he has to make a choice in order of urgency.
2. Limited resources - The resources are limited in relation to need for them. It is the main cause of economic problem.
3. Alternative use of resources - A resource can be utilized in a different way and for different purposes. Therefore choice has to be made among different uses of resources.

Value based question:-
Q1 A basic economic problem is that there is oil shortage in INDIA. What measures do you suggest to mee t the growing demand of oil?
Ans:-Measures taken are : 1) oil is limited so it should be efficiently and fully(optimum use)used.
2)Massive awareness on shortage of oil and people should be encouraged
to use public transport system.
Q2. The state govt. has sanctioned acertain amount to increase production in rural areas. Which technique of production will you suggest to the state govt. for this project?
Ans.:-Labour intensive technique of production.
Q3. Why is it that on one hand coal is found in plenty, yet it is scarce , while a rotten fruit is rare but not scarce?
Ans:- Coal is scarce because its demand is greater than its supply.A rotten fruit is not scarce because there is no demand for rotten fruits.
Q4. For a devolepmental project, logs of wood another building material have to be carried to the upper floor of building under renovation by the labour .Alternatively elevators and lifts can do the job ,which one will you choose and buy?
Ans:- I will choose the second alternative as it is efficient and time and money saving method.
Q5. If more and more resources are constantly explored and new and new technique of production are constantly discovered,don‟t you think a day will come when our central problems will be solved once for all?
Ans:-When new resources are explored and new technology is discovered,PPC wouldexpand,indicating larger and larger flow of goods &services in the economy.But our wants are limlted, so scarcity of resources in relation to human wants will always exist.And,so long as limited resources are to colliding with unlimited wants,central problems can never be solved once for all.

Utility Analysis Utility - Want satisfying Power of a good. Cardinal Utility – It says that utility can be measured in number. (Quantitative Concept) Ordinal Utility – It says that utility being a mental concept can‟t be measured in number. (Qualitative Concept) Total Utility – It is the sum total of Utility derived from the consumption all units of consumption.TU= Sum of MU Marginal Utility – It refers to the additional utility on account of consumption of an additional unit of commodity. MU=TUn-TUn-1
Consumption of x TU MU
1 20 20 2 36 16 3 46 10 4 50 4 5 50 0 6 44 -6 7 42 -2 8 38 -4
Law of Marginal Utility – The law says that when a consumer consumes more and more amount of one commodity, the utility derived from successive units of commodity will go on declining.
Consumer Equilibrium- Consumer‟s equilibrium is a situation where the consumer maximises his satisfaction out of his limited income. Indifference Curve - It refers to the locus of all possible combinations of two commodity which gives equal level of satisfaction to the consumer. Budget line – It is the locus of all possible combinations of two commodities which can be purchased at a given level of income.
Question and Answer 1. What do you mean by monotonic preference?
Ans . it mean that a rational consumer always prefer more of a commodity as it offers him a higher level of satisfaction.
2. What price the consumer is ready to pay for a commodity in a state of his equilibrium?
Ans:- in a state of equilibrium the price that the consumer is ready to pay is exactly equal to the price prevailing in the market . Because, in a state of equilibrium , money worth of marginal utility that the consumer gets is exactly equal to market price he has to pay.
3. What happen when Mux/Px is greater than MUy/Py ? Ans. This situation implies that by spending a rupee on Good –X the consumer gets grater marginal utility that in case of Good-Y. Accordingly, he will spend more on X than Y .As consumption of X rises, Mux will fall .On other hand ,as consumption of Y falls ,MUy will rise. The consumer will stop buying more of X in place of Y only when Mux/Px=MUy/Py. It is here only that the equilibrium is struck.
4. How is equilibrium of the consumer affected when Mum happens to rise ,and Px is constant. Ans . Equilibrium is struck when Mux/Px=Mum. If MUm rises and price is constant ,the consumer will be off the point of equilibrium .Because Mux/Px would then be less than Mum . the consumer will reach back his equilibrium only if Mux rises ,as Px is given to be constant . This will happen only when consumption of commodity –X is decreased.
5. How will the consumer move along his IC in a situation when MRSxy> Px/Py Ans. The consumer should move downward to the right along the IC . Convexity of the IC ensure that as the consumer moves downward to the right along his IC, MRSxy tends to fall. Implying that the consumer should start consuming more of X in place of Y.
6. How will a consumer adjust his consumption of Good-X and Y in asitution when MRSxy=Px/Py Ans. The consumer should start consuming more of Y in place of X . That is, he should move upward to the left along the IC . Convexity of the Ic ensure that as the consumer moves upward to the left along his IC , MRSxy tends to rise . He should stop at a point when MRSxy=Px/Py
7. Why should a consumer buy more of a commodity even when MU of every successive units tends to decrease Ans. Even when MU is decreasing ,its money worthy still be greater than the price he has to pay. We know ,the consumer stops buying a good only when its money worth of MU is equal to its price.
8. State the condition of consumer‟s equilibrium.
Ans. Hint: A consumer strikes his equilibrium when rupee worth of marginal utility actually received by the consumer is equal to marginal utility on money Mux/Px=Mum
Demand and Law of Demand Demand – Demand for a commodity is defined as the amount of commodity which a consumer purchase at a given price and at a given time. Individual Demand – It shows the amount of commodity purchased by an individual consumer at a given price and at given time. Market Demand – It shows the amount of commodity purchased by all consumers present in the market at a given price and at a given time. Demand function – It is the functional relationship between the quantity demanded and the factors affecting it. Symbolically it is written as Q = f( P R I N T), where
P-Price of the commodity, R- Price of the related commodity, I – Income of the consumer
N – Number of consumer, T – Taste and Habits and Preference of the consumer Law of Demand- Law of demand says that other thing remaining same more is demanded at a less price and less is demanded at a high price. Hence there exist an inverse relationship between the price and quantity demanded. Change in demand – When quantity demanded of a commodity changes due to change in the other factors, price of the commodity remaining constant, it is called change in demand. It is also called movement of the demand curve. It is of two types such as a) Increase in Demand
b) Decrease in demand and Increase in Demand – When quantity demanded of a commodity increases due to positive changes in the other factors, price remaining constant, it is called increase in demand.
Decrease in Demand – When quantity demanded of a commodity decreases due to negative changes in the other factors, price remaining constant, it is called decrease in demand. Change in quantity demanded – When quantity demanded of a commodity changes due to change in its price, other factors remaining constant, it is called change in quantity demanded. It is also called movement along the demand curve. It is of two types such as:-
a) Expansion in demand b) Contraction in demand.
Expansion in demand – when quantity demanded of a commodity increases due to fall in the price of the commodity, it is called expansion in demand.
Contraction in demand – When quantity demanded of a commodity decreases due to rise in the price of the commodity, it is called contraction in demand.
Elasticity of demand Price elasticity of demand- It is defined as the degree of responsiveness in the quantity demanded of a commodity due to change in its price, other factors remaining constant. Factors affecting price elasticity of demand: 1. Nature of commodity 2. Availability of Substitutes 3. Diversity of uses 4. Income level of the buyer 5. Habit of the consumer 6. Proportion of income spent on a commodity 7. Time Period 8. Postponement of use Methods of measuring price elasticity of demand - There are three methods of measuring price elasticity of demand. These are 1. Percentage Method
2. Total expenditure method 3. Geometric Method
Percentage Method: By percentage method the price elasticity of demand is measured by taking the ratio between the percentage change in quantity demand and the percentage change in price.
Ed= (-) % Change in quantity Demanded/
% Change in price. Ed = q1-q/q*100
P1-p/p*100 = Δq/q
Δp/p = Δq/q *p/Δp Ed = p/q * Δq/ Δp
Question and Answer 1. If the quantity demanded of a commodity „X‟ decreases as
the household income increases, what type of good is „X‟?
Ans. Inferior good. 2. Write down one factor responsible for increase in demand.
Ans. Rise of income or favourable taste for a good. 3. At the given price when will be the demand of a commodity be less?
Ans. Fall in the income. or
Ans. Fall in the price of a substitute good.
4. When two demand curves intersect with each other which will be more elastic. Ans. The demand curve which is more flattered will be more elastic.
5. If the demands for good „Y‟ increases as price of another good „X‟ rises
how the two goods are related? Ans. These are substitute goods.
6. Answer in one sentence the assumption on which a demand curve is constructed Ans. That all the determinates are constant.
7. What is cross price effect? Ans. Cross price effect refers to the effect of change in the price of commodity-X on the demand for commodity Y when X and Y are related goods.
8. What types of goods find a rise in their demand even income of the buyer reduces? Ans. Inferior goods
9. Why is demand for water inelastic ? Ans. Demand for water is inelastic ,as water is an essential of life.

2. Why more is purchased when price falls? Or
Why does demand curve slope downwards?
Ans. (a)Income effect: - change in real income due to change in price is income effect. When price falls real income increases that why a person purchases more.
(b)Size of consumer groups: - when price falls the demand extends because the persons who were not purchasing earlier. They also start purchasing.
(c)Substitution effect: - when the price of a substitute good increases the demand of the given god increases as it is relatively cheaper.
(d)Law of diminishing marginal utility:- by using more and more units of a commodity the marginal utility from each successive unit goes on decreasing. This is why the consumer buys more commodities at low price. 3.Explain with the help of diagram, the effect of the following changes on
the demand of a commodity.
10. Fall in the price of a substitute good .
11. Fall in the income of its buyers.
Ans. (a) Fall in the price of a substitute good will cause fall in the demand of
the given commodity from 0q to 0q1. the demand curve will shift
towards left to d1d1
(b) Fall in the income of its buyer will cause fall in the demand of normal
goods from 0q to 0q1. the demand curve will shift towards left from dd

Q1. Distinguish between substitute and complementary good. Give example in each case.
Ans:- Substitute good:- Goods which are demanded in place of one another is known as substitute goods. For example-tea and coffee, wheat and rice, bike and scooter etc.
Complementary good:- Goods which are jointly demanded is known as complementary good. For example-car and petrol, bread and butter, pen and ink etc.
Q2. Explain the effect of change in income of the buyers of a good on its demand.
Ans:- As we know that the income of the consumer either increase or decrease and a rational Consumer behaves accordingly. Incase if consumer income raises then ultimately the demand will also increase and if consumer‟s income decline then consequently he will demand less due to fall in income.(student may take an example to explain the concept by taking the case of normal and inferior good).
Q3. Distinguish between individual demand and market demand.
Ans:- Individual demand:-Demand of a particular commodity by an individual consumer in the market is known as individual demand. For ex- Ram‟s demand for milk.

PRODUCER BEHAVIOUR AND SUPPLY (16 Marks)
A. PRODUCTION FUNCTION: TOTAL PRODUCT, AVERAGE PRODUCT, MARGINAL PRODUCT, RETURNS TO A FACTOR & PRODUCER‟S
EQUILIBRIUM BASIC CONCEPTS:
1. Production function: refers to the technological relation between physical inputs and physical output. It is the technological knowledge that determines the maximum level of output that can be produced by employing different levels of inputs. It is expressed in terms of a function as follows:
q = f (x1, x2),
where x1 is the amount of factor1, x2 is the amount of factor2, and „q‟ is quantity of output to be produced.
2. Total Product: refers to total quantity of goods produced by a firm during a given period of time by varying the units of a variable input like factor 1.
3. Average product is defined the output per unit of a variable input, say, factor1.
That is, AP1 = TP/x1.
4. Marginal product refers to addition to total product, when one more unit of
variable factor is employed, that is, MP1 = = TPn –TPn-1
5. Short Run and Long Run: Short run is a period in which some factors are variable (variable input) and other factors remain fixed (fixed input). On the other hand, in the long run, all factors of production are variable, nil is the fixed factor.
6. Returns to a factor refers to change in total product due change in only the variable input in the short run, while fixed inputs remain constant.
7. Law of Variable Proportion: states that if we go on increasing more and more units of a variable factor with fixed factor remain constant, total product increases at an increasing rate, but beyond a certain level of employment total product increases at a decreasing rate and finally TP falls.
8. Law of Diminishing Marginal Product states that if we keep on increasing the employment of a variable input with other inputs fixed, finally a point will be reached after which the marginal product will start falling.
9. Relation between: (i) TP and MP, and (ii) MP and AP in terms of a schedule:
Factor1 TP1 MP1 AP1 O 0 - - 1 10 10 10 2 24 14 12 3 40 16 13.3 4 50 10 12.5 5 56 6 11.2 6 57 1 9.5 7 57 0 8.1 8 56 -1 7
(i) From the above schedule, the relation between TP and MP is derived as follows:
Stages I:IncreasingReturnto factor1(uptofactor employment level 3 units ) II: Diminishing Return to factor 1 (from 4units to 0 unit) III: Negative Return to factor1 (after 7 units)
TP1
Increases at increasing rate
Increasesat diminishing rate
Starts falling
MP1
an Increasing
a Diminishing
Negative
* When TP is maximum, MP is zero.
(ii) From the above schedule, the relation between MP and AP is derived as follows:
(a) When AP rises, MP is higher than AP,
(b)When AP falls, MP is less than AP, and
(c) When AP is maximum, MP =AP,
(d) MP may be positive, zero or negative but AP is always positive.
10. Reasons for the operation of increasing returns to a factor:
(i) better utilization of the fixed input with increase in variable input,
(ii) benefits of division and specialization of the variable input used, say, labour,
(iii) indivisibility of fixed input.
11. Reasons for the operation of diminishing return to a variable input, say, labour:
(i) optimum combination between fixed and variable inputs is disturbed with increasing use of the variable input,
(ii) After a certain level of employment of the variable input, the benefits from the division of labour will diminish leading to diminishing return.
(iii) imperfect substitutes between fixed input and variable input.

B.COST & REVENUE:
Meaning-Cost means the total expenditure incurred in the Production of a commodity. Broadly Costs are of two types:- Short-run costs & Long-run costs.
Short run costs-Short-run is a period of time when some factors are fixed and some factors are Variable. Expenditure incurred in the Production of a commodity in the short-run is known as short-run cost.
Long-run costs-Long-run is a time period when all the factors are variable. Expenditure incurred in the production of a commodity in the long-run is known as Long-run cost.
Types of Short-run costs:
1. Total Fixed Cost (TFC)-Expenditure incurred on the fixed factors of production
are known as Total fixed costs. Fixed costs do not vary with change in output.

TFC=TC-TVC
2. Total Variable cost (TVC)- Expenditure incurred on the variable factors of production are known as Total Variable Cost. Variable costs vary with change
in output. TVC=TC-TFC
Total Cost (TC)-Total Cost is the total expenditure incurred on the production
3. of a commodity. It is the sum total of Total Fixed Cost and Total Variable Cost.
TC=TVC+TFC Average Fixed Cost (AFC)-AFC is obtained by dividing the Total Fixed Cost By the total number of units produced.
4. AFC=TFC/Q Average Variable Cost (AVC)-AVC is obtained by dividing the Total Variable Cost by the number of units produced.
AVC=TVC/Q
5. Average Total Cost (ATC)-ATC is obtained by dividing the Total Cost by the number of units produced.
ATC=TC/Q Marginal Cost (MC)-Marginal cost is the addition made to the total cost by
6. producing an additional unit of Output. MC = ∆TC/∆Q, MCn = TCn-TCn-1

Cost Schedule:
Out Put 0 1 2 3 4 5 6 7 8 9 10
Diagrams: MARGINAL AND AVERAGE COSTS:
Marginal cost curve is U-Shaped because:
MC falls in the beginning because of increasing return to a factor(decreasing cost ) and then increases due to diminishing return to a factor(increasing costs).
Relationship:
1. Between Total Cost and Marginal cost. MCn =TCn-TCn-1 When Total Cost increases at a diminishing rate Marginal Cost decreases. When Total Cost increases at an increasing rate Marginal Cost increases.
2. Between Total Variable Cost and Marginal Cost. MCn =TCn-TCn-1 When Total Variable Cost increases at a diminishing rate Marginal Cost decreases. When Total Variable Cost increases at an increasing rate Marginal Cost increases.
3. Between Average Variable Cost and Marginal Cost. When MC ‹ AVC, then AVC falls. When MC =AVC, then AC is Minimum. When MC› AVC, then AVC rises. MC curve always intersect AVC at its minimum point.
4. Between Average Total Cost and Marginal Cost.
When MC ‹AC, then AC falls. When MC =AC, then AC is Minimum. When MC ›AC, then AC rises. MC curve always intersect AC curve at its minimum point.
REVENUE
Revenue is the total money receipt of the firm from sale of its product.Three main concepts of revenue are total revenue, marginal revenue, and average revenue.
Total Revenue refers to the total money receipt of the firm from the sale of its total output
TR = Number of units sold (Q) x price per unit (p)
TR = P X Q
Average Revenue: AR is revenue per unit of output sold.
MARGINAL REVENUE: It is the addition to total revenue when an extra unit of output is sold.
MR = TRn – TR n - 1
Relationship between AR & MR
i) If AR is constant MR is equal to AR
ii) If MR is above AR, AR increases.
iii) If MR is below AR, AR decreases.
AR and MR in Perfectly competitive market:
AR, MR
Output
AR = MR
In this market price or AR is constant. So MR isequal to AR. Both are represented by the same horizontal line parallel to OX-axis.
AR & MR in non-competitive markets
1) The average revenue curve and marginal revenue curve slope downward from left to right.
2) Since AR falls MR curve lies below the AR curve.
3) MR falls twice the rate of fall in MR.
Relationship between TR & MR:
1) As long as MR is positive TR increases.
2) When MR increases TR increases at increasing rate.
3) When MR decreases, but positive TR increases at decreasing rate.
4) When MR is zero TR is maximum.
5) When MR is negative TR diminishes.

C. THEORY OF SUPPLY:
1. Supply:
It is that quantity of a commodity which a seller or producer is ready to sell in the
market at a certain price within a given time period.
Factors Affecting Supply of the commodity:
1) Own price of commodity
2) State of technology
3) Prices of factors of production
4) Taxation policy
5) Price of related goods
6) Other factors like natural calamities.
Law of Supply: Other things being constant, there is a direct relation between price
of a commodity and its quantity supplied i.e. higher the price more the supply and
vice-versa.
Supply Schedule: It is a schedule / table showing different quantities supplied of a
commodity by a seller at different prices.
Price Quantity
Supplied
5 20
4 15
3 12
2 10
Supply Curve -If supply schedule is shown on a graph, we get a curve which is
called supply curve.
Market Supply: It is the horizontal summation of the supply of a product by all the
producers in the market at a given price and at a point of time.

Diagrammatic Presentation:
Change in Quantity Supplied: When there is change in supply of a commodity due
to change in price (This is movement along the supply curve)
This Change is of two types.
1) Expansion in supply -Supply increases due to increase in price
(Figure 3.10)
2) Contraction in supply -Supply decreases due to decrease in price.
Change in Supply -(Shift in supply curve) When supply of a commodity changes
due to factors other than price, like technique, taxation policy, prices of factors of
production etc. This is called change in supply.
This change is of two types:
a) Increase in supply -when supply of a commodity rises due to factor other than
price it is increase in supply. In this case the supply curve shifts rightward.
b) Decrease in supply -when supply of a commodity falls due to factors other than
price it is decrease in supply. In this case the entire supply curve shifts to the left
(upward).
(Figure 3.11)
Price Elasticity of Supply:
It is the measurement of degree of change in supply of a commodity to change in its
price.
Es = % change in quantity supplied / % change in price
Es = x P
S
Factors Affecting Elasticity of Supply:
1. Nature of commodity
Durable goods -Elastic
Non-durable -Inelastic
2. Change in cost of production -
3. Technique of production
4. Time period.
Methods of Measuring Elasticity:
1. Percentage method or Proportionate method.
Es = % Change in QS or % change in price
2. Geometric method
a) Es > 1
Proportionate change in Supply = S x P
Proportionate change in PriceS x
(Figure 3.12)
b) Es = 1 Supply curve passes through origin.
c) Es < 1
(Figure 3.13)

10. Demand for a good is elastic whereas its supply is inelastic. What impact it will have, when demand for good increases? Explain.
Ans. When supply is inelastic, it means supply for such a product cannot be increased. Now when demand for it increases, it will raise price for such a good.
11. “Supply of agricultural goods is inelastic”. Explain.
Ans. Yes, it is true that supply of agricultural goods is inelastic because it is not inspired by price-rise rather it depends upon natural, climatic and biological factors. Such goods take lot of time in its production, therefore no price-frame can guide there production.
12. Imports of production with less elastic supply can fetch higher revenue. Explain.
Ans. True, those imported goods which are inelastic or less elastic like petrol and diesel and can fetch higher revenue. It is because of the reason that such goods will be sold at high price because of limited supply. Therefore, the yield from such import will be higher.

21. In your opinion, which market can yield more revenue – perfect competition or monopoly?(3) Ans. Under perfect competition, price is kept as competitive which results into higher sale and higher revenue. On the other hand under monopoly, monopolist wants to change a higher price and sales lower amount of good. It therefore, under perfect competition, there is larger revenue earned with lesser amount of profits.
22. Suggest a suitable price policy that helps a firm to make value addition.
(3) Ans. A firm should adopt following of price policy for promoting its sale and overall revenue of the firm. (i)Keep a competitive price that helps a firm to raise its sale. (ii)Spend some amount on advertisement of the good show as to attract new
buyers. (iii)Provide cash discounts, guarantee of qualitative product, and home delivery
of goods and warranty of durable goods.
23. Why equilibrium is essential for a producer? (1)
Ans. Because it will help him in maximizing profits. 24. Given below is AC and price of different units produced by a firm. Determine

Output (units) 50 60 70 80
Output Price (Rs.) Average cost Total revenue (Rs Total cost (Rs Total profit
(units)(Rs.)(Rs.) 50 20 15 1000 750 250 60 20 15 1200 900 300 70 20 18 1400 1260 140 80 20 20 1600 1600 0
Ans. Producer will be in equilibrium, when he produces 60 units [he earns maximum amount of profit in this situation.
25. Under perfect competition, when a producer would gain higher profits, during short period or long period.(3) Ans. During short period, a producer has risk of earning losses as well as super normal profits. But during long period, he will earn normal profits by which his aggregate amount of profits will be higher. It is therefore long period yields higher amount of profits to the producers.
26. Demand and Supply equation for a product are given below: (3)
Yd =100-P Ys =70+2P
Determine equilibrium price and quantity.
Ans. Under equilibrium:
Yd = Ys
100-P = 70+2P 30 = 3P P = Rs. 10
Putting the value of P in the equation Yd =100-10 = 90 units Ys =70+2(10) = 90 units
Therefore, equilibrium quantity = 90units
UNIT IV
FORMS OF MARKET AND PRICE DETERMINATION UNDER PERFECT COMPETITION WITH SIMPLE APPLICATIONS
(12 MARKS)
Market: It refers to a region in which buyers & sellers interact with each other – may be directly or indirectly – in order to exchange the commodities at certain price.
Types of Market: Market can be categorised on the basis of time, location and competition. On the basis of competition, the market is classified into two categories i.e. perfect and imperfect markets.
Perfect market / competitive market- It refers to such a market structure where the firms are price takers and the price of the good remains same.
Imperfect market/ non-competitive market- It refers to the market structure where the prices of the goods differ and firms are not only price taker but also price maker.
Perfect Competition Market: It refers to such a market structure where there are large numbers of buyers and sellers and firm sell a homogenous product at uniform price.
Characteristics / Features/ Conditions of the perfect competitive market
1. Large number of buyers and sellers – There are large number of buyers and
sellers in perfect competitive market it means no single buyer or seller can influence the market It is because each seller sells a very small portion of the market supply, similarly the demand of each buyer is also very small in the market.
2. Homogeneous product - The product sold in the market is homogeneous or identical in all respect i.e. shape, size, colour, composition, etc.
3. Free entry and exit of firms - Under perfect competition there are no barrier to entry and exit of firms in industry. But entry and exit may take time so it happens only in long runs. This freedom ensures that firms earn just the normal profits in the long run.
4. Perfect knowledge of market- In this market all the sellers as well as buyers have the complete information about the market situation. It means they are well aware about the product and its price. Thus the price remain same.
5. Perfect mobility– The factors of production i.e. land, labour, capital and entrepreneur are perfectly mobile. There is no geographical and occupational restriction on their movement. It means factors of production are free to move from one place to another place and one job to another job in which they get better price.
6. No selling and transportation cost- It assumes that there is no selling and transportation cost. Thus the price remains same everywhere.
Monopoly – It‟s a market situation where there is a single seller of a commodity which has no close substitutes.
Main features of a monopoly market are-
1. Single seller- Under monopoly there is an only seller of commodity in the
industry, so the difference between firm and industry get vanished. It means the monopolist has full control over the supply and price of commodity.
2. No close substitute- The monopolist produces a distinct product which has no close substitute in the market. Therefore the monopoly firm has no fear of competition from any other commodity.
3. Barriers on entry- There are strong or significant barrier to the entry of new firms. These barriers may be legal barriers like patent right or licensing etc.; as a result monopolist firm can earn abnormal profit in the long run.
4. Price discrimination- When a monopolist charge different prices from different buyers for the same product is called price discrimination. It‟s a distinct feature of monopoly market. E.g. railways charge different fare for senior citizens, children and others for same journey.
5. Independent price policy - In monopoly, firm and industry are same so the firm has complete control over the output and it fixes its price by itself. Thus firm is price marker in monopoly.
Monopolistic Competition- It refers to such a market structure where there are large number of buyers and sellers and the firms produce & sell differentiated product which has many close substitute available.
Characteristics /feature/conditions-
1. In this kind of market situation, there exist a fairly large number of firms which
have a greater competition among themselves. Due to this, the firms do not have total control over the market supply of the product.
2. The firms produce & sell heterogeneous (differentiated) products, in this kind of markets, which enable the firms to have control on their own output, & thus the firms are price makers.
3. There is a freedom of entry & exit of firms in the market, to a considerable extent, due to which the number of firms always remain fairly large. As a result, the firms can earn only the normal profits in the long run.
4. The unique feature of this type of market situation is prevalence of selling cost, i.e. the expenditure made by the firms to promote the sales of their products viz. sale exhibition, discount offer, showroom demonstration, advertisement & wide campaigning cost etc.
5. The firms, in this type of markets, are price makers, as all these firms have distinct consumers of their product. As the firms produce & sell differentiated product, the price of products of each firm is different, irrespective of their similarity. Because of this, the AR (demand) curve slopes negatively at gradual rate.
Oligopoly is a market structure in which there are few large sellers of a commodity, which sell homogenous and differentiated product.
If in an oligopoly market, the firms produce homogeneous products, it is called perfect oligopoly.
If the firms produce differentiated products, it is called imperfect oligopoly.
Collusive oligopoly is one in which the firms cooperate with each other in deciding price and output.
Non collusive oligopoly is one in which firms compete with each other.
Features of oligopoly
1. Few firms - Few firms mean either only a few firms in number or a few big firms producing most of the output of the industry. The exact number of firms is not defined. The word „few‟ signifies that the number of firms is manageable enough to make a guess of the likely reactions of rival by a firm.
2. Firms are interdependent in taking price and output decisions -When there are only a limited number of firms, it is likely that rivals have some knowledge as to how these firms operate. It one firm does something about the price and quantity of the product it produces, the rivals are likely to take quick note of it and
react by changing their own price and output plAns- It makes each firm dependent on other firms in the industry.
3. Barriers to the entry of firms- The main reason why the number of firms is small is that there are barriers which prevent entry of firms into industry. Patents, large capital, control over the crucial raw materials etc. prevent new firms from entering into industry. Only those who are able to cross these barriers are able to enter.
4. Non-price competition- Firms try to avoid price competition for the fear of price war. They use other methods like advertising, better services to customers, etc to compete with each other.

demand curve Short answer question(For High Achievers) ( 3&4 Marks)
4. Explain briefly why a firm under perfect competition is a price taker not a price maker? Ans - A firm under perfect competition is a price taker not a price maker because the price is determined by the market forces of demand of supply. This price is known as equilibrium price. All the firms in the industry have to sell their outputs at this equilibrium price. The reason is that, number of firms under perfect competition is so large. So no firm can influence the price by its supply. All firms produce homogeneous product.
5. What are the reasons which give emergence to the monopoly market?
Ans- The main reasons are as under- i) Patent Rights- Patent rights are the authority given by the government to a particular firm to produce a particular product for a specific time period. ii) Formation of Cartel- Cartel refers to a collective decision taken by a group of firms to avoid outside competition and securing monopoly right. iii) Government licensing- Government provides the license to a particular firm to produce a particular commodity exclusively
6. Why is demand curve facing a monopolistic competition firm likely to be more elastic? Ans- In monopolistic competition market the demand curve of a firm is likely to be more elastic, the reason behind this is that all the firm in the industry produce close substitute of each other. If close substitute of any good is available in the market then elasticity of demand is very high because whenever there is a hike in price the consumer will shift to its substitutes. That is why a firm„s demand curve under monopolistic competition is more elastic.
7. Explain how the efficiency may increase if two firms merge. Ans- When two firms merge then there combined efforts and efficiency brings more output to the firm. Increase in the sale of output and economies of scale can be availed. It leads to division of labour and can get advantage of the specialization. Use of better and advanced technology saves the cost of production.
8. Explain the implication of the feature product differentiation under
Monopolistic competition. Ans- Product differentiation is a distinct feature of monopolistic market. It means that buyers differentiate between the products produced by different firms. Therefore, they are willing to pay different prices for the products of
different firms. Different groups of buyers prefer products of different firms. This gives an individual firm some monopoly power, i.e. power to influence the demand for its product by changing price.
9. Explain the implication of the feature freedom of entry & exit of firms under perfect competition. Ans- Free entry and exit of firms: It means that there is no barrier for entry and exit of firms in the industry. This freedom ensures that firms earn just the normal profits in the long run. If the existing firms earn above-normal profits, new firms enter in the industry, raise supply, which brings down the price. The profits fall till each firm is once again earning only the normal profits.
If the existing firms are having losses, the firms start leaving, supply falls and price goes up. The price continues to rise till the losses are wiped out and firms are just earning normal profits.
Price determination under perfect competition
Under perfect completion price of commodity is determined by demand and supply of a commodity in an industry.
Equilibrium price is the price at which demand and supply of commodity are equal.
The market equilibrium is determined by equality between quantity demanded and quantity supply. It means at equilibrium point - Quantity demanded = Quantity supplied
The price determined at equilibrium point is called equilibrium price.
The price has a tendency to persist. If at a price , market demand is not equal to market supply there will be either excess demand or excess supply and the price will have tendency to change until it reach a point where demand and supply are equal.

In the above schedule and diagram market equilibrium is established at a price of ₹ 3 per unit, because at this price both the market demand and market supply are equal.
Suppose a price is less than the equilibrium price and if it is ₹ 2 per unit. At this price market demand is greater than market supply. It is called an excess demand situation. In this case the buyers will not be able to buy all what they want to buy. The pressure of excess demand will push the market price up. This will have two effects. Extension of supply and contraction of demand. The tendency of supply going up and demand going down will continue till market supply becomes equal. This is achieved at price ₹ 3 per unit. The equilibrium is restored and vice versa. Ceiling Price: it refers to fixing the maximum price of a commodity at a level lower than the equilibrium price. Floor Price: it refers to the minimum price (above the equilibrium price), fixed by the government, which the producers must be paid for their produce.
Q- How an increase in demand of a commodity affect the equilibrium price? Explain
Ans- When demand of commodity increases it lead to excess demand situation at equilibrium point. So competition among the buyers‟ increase. Hence price of commodity increases.
We can explain it with the help of diagram as follows In the diagram, demand and supply of good are equal at point E. So E is equilibrium point. At this
Y
D
Price D

point OP is equilibrium price and OQ is equilibrium quantity. When demand increases,
S demand curve shifts to right i.e. D1 D1, then at OP price there is EF excess demand. This results competition among buyers which will raise the
E price. Due to increase in price there will be contraction of demand and extension of supply.
E This reduces the gap between quantity demanded F and quantity supplied.
D
S
O Q Q Q
D
X Quantity
These changes will continue till we reach the new equilibrium point E 1 where quantity demanded is equal to quantity supplied.
Now OP1 is new equilibrium price. Since new equilibrium price [OP1] is higher than the old equilibrium price [OP] which shows that equilibrium price has increased.
Q- How an increases in supply of a commodity affect the equilibrium price? Explain
Ans- An increase in supply of a commodity results in a rightward shift of supply curve as shown by dotted supply curve in the diagram which lead to decrease in price It can be explain by diagram as follow -
We can explain it with the help of following diagram:

In diagram, demand and supply of good are equal at point E. So E is equilibrium point. At this point OP is equilibrium price and OQ is equilibrium quantity. When supply increases new supply curve S1S1 shifts to right, it shows that at OP price, there is EE2 excess supply. This excess supply results competition among the sellers leading to fall in the price. A fall in price results in rise in quantity demanded (a downward movement along the new demand curve) and fall in quantity supplied (a downward movement along new supply curve).
O Q Q1 Q2
Quantity
These changes continue till quantity demanded and supplied are equal at point E 1. So E1 is new equilibrium point and OP1is new equilibrium price.
Since OP1< OP which shows that equilibrium price has decreased.
Q.1. When will equilibrium price not change even if demand and supply increase? Ans: - When proportionate increase in demand is just equal to proportionate increase in supply. Equilibrium price will not change. It can be shown in the following diagrams.
Price D D′ S S′

O Q Q1
E1E
In the above diagram increase in demand is just equal to increase in supply. Demand curve shift from D to D1 and supply curve shift from S to S1 which intersect at point E. Thus equilibrium price remain unchanged at OP though equilibrium quantity increased from OQ to OQ1.
Q.2 . How does increase in price of substitute goods in consumption affect the equilibrium price of a good? Explain with a diagram. Ans:- An increase in price of substitute goods (coke) will cause increase in demand for its related goods (Pepsi) . The demand curve for Pepsi will shift to the right side.
The supply curve of Pepsi remains the same. It will lead to an increase in equilibrium price of Pepsi and increase in quantity also.

Macro Economics: Macroeconomics is the study of aggregate economic variables of an economy. It studies the economy as a whole.
Consumption goods: Consumption goods can be defined as the goods which are bought by consumers as final or ultimate goods to satisfy their wants. e.g: Durable goods like -car, television, radio etc. Non-durable goods and services like- fruit, oil, milk, vegetable etc.
Semi durable goods such as- crockery etc. Compulsory goods, like – medicine, rice, pulses, edible oil etc.
Capital goods Capital goods can be defined as the goods, which are used and help in the process of production of other goods and services. E.g.: plant, machinery, land, buildings etc.
Final goods: Final goods can be defined as the goods, which are used either for final consumption or for investment. It includes final consumer goods and final production goods. They are not meant for resale. So, no value is added to these goods. Their value is included in the national income.
Intermediate goods Intermediate goods can be defined as the goods, which are used either for resale or for further production. Example for intermediate good is- milk used by a tea shop for selling tea. Wheat flour for baking bread, cake etc.
Stock: Quantity of an economic variable which is measured at a particular point of time. Stock has no time dimension. Stock is static concept. Eg: wealth, water in a tank.
Flow: Flow is that quantity of an economic variable, which is measured during the period of time. Flow has time dimension- like per hr, per day etc. Flow is a dynamic concept. Eg: Investment, water in a stream.
Investment: Investment is the net addition made to the existing stock of capital. It can be defined as the expenditure made on creation of assets or final goods like: Purchase of land, Buildings, Machines, establishment of power plants, construction of dams, etc. It is also called as Gross investment, because, it also include depreciation value of assets.
Net Investment It can be defined as the difference between Gross Investment and Depreciation value of the assets. Net Investment = Gross investment – Depreciation.
Depreciation: Depreciation refers to fall in the value of fixed assets due to normal wear and tear, passage of time and expected obsolescence. It is also known as the consumption of fixed capital during production process.
Circular flow of National Income:
It is a pictorial illustration of interdependency between the major sectors of the economy.
It refers to flow of money income or the flow of goods or services across different sectors of the economy in a circular form.
Types of Circular flow :
1. Product Flow (Real Flow): This is the flow of factor services and
flow of goods.
2. Income Flow: This refers to the money flow in the form of factor
payments and consumption expenditure.
Significance of Circular flow of Income :
1. Knowledge of Interdependence. 2. Size of National income. 3. Level of Economic Activity. 4. Injections and Leakages.
Circular Flow of Income in a Two Sector Economy: 1. The circular flow in a two sector economy will keep on flowing without end as
there is no leakage from and injection in the income stream.
2. Whatever is produced by firms is consumed by the household sector.
3. Factor payments by firms are equal to factor income of household sector.
4. Whatever is the factor income of the household sector is spent on consumption.

RESIDENT:
A resident, whether a person or an institution, is one whose centre of economic interest lies in the economic territory of the country. In which he lives or is located. INDIRECT TAXES:
The burden of these taxes is shifted to buyers. Since the burden indirectly falls on
buyers. They are called indirect taxes e.g. sales tax, excise duty etc.
SUBSIDIES: Subsidies are financial assistance by government to enterprises on
production of a certain commodity. The effect of subsidies is to bring down the price
like: indirect tax it is also generally passed on to the consumers.
Gross Domestic product at market price It is the money value of all final goods and services produced during an accounting year within the domestic territory of a country. Domestic territory means the geographical boundaries of the nation.
Gross National product at market price: It is a money value of all final goods and services produced by a country during an accounting year including net factor income from abroad.
GNPmp = GDPmp + NFIA Net factor income from abroad: Difference between the factor incomes earned by our residents from abroad and factor income earned by non-residents within our country. Factor income earned by non-residents is also known as the factor income to abroad.
NFIA = FIFA – FITA Where, FIFA = Factor income from abroad.
FITA = Factor income to abroad.
Components of Net factor income from abroad
Net compensation of employees

Concept of domestic (economic) territory:
Domestic territory is a geographical territory administered by a government within which persons, goods and capital circulate freely. (Areas of operation generating domestic income, freedom of circulation of persons, goods and capital)
Scope identified as *Political frontiers including territorial waters and air space. *Embassies, consulates, military bases etc. located abroad but including those locates within the political frontiers. *Ships, aircrafts etc., operated by the residents between two or more countries. *Fishing vessels, oil and natural gas rigs etc. operated by the residents in the international waters or other areas over which the country enjoys the exclusive rights or jurisdiction. Resident (normal resident):- Normal resident is a person or an institution who ordinarily resides in that country and whose center of economic interest lies in that country. (The Centre of economic interest implies :-( 1) the resident lives or is located within the economic territory. (2) The resident carries out the basic economic activities of earnings, spending and accumulation from that location 3. His center of interest lies in that country.
Relation between national product and Domestic product.
Domestic product concept is based on the production units located within domestic (economic) territory, operated both by residents and non-residents. National product concept based on residents and includes their contribution to production both within and outside the economic territory.
National product = Domestic product + Residents contribution to production outside the economic territory (Factor income from abroad) - Non- resident contribution to production inside the economic territory (Factor income to abroad)
Methods of calculation of national income
1- PRODUCT METHOD (Value added method):
Value of output = Sales + change in stock
Change in stock = closing stock – opening stock
Gross value added (GDPMp) = Value of output - Intermediate consumption
NNPfc (N.I) = GDPmp - consumption of fixed capital + Net factor income from abroad - Net indirect tax.
2- INCOME METHOD: Components are: 1. Compensation of employees. (wages, Salary and contribution made by the employers) 2. Operating surplus.
Income from property
Rent & Royalty Interest
3. Mixed income of self-employed. Thus ,
Income from Entrepreneurship
Profit
CorporateCorporatedividend TaxSavings
(Net retained earnings)
NDP fc = Compensation of employee + Operating Surplus + Mixed income of the self employed.
NNP fc = NDP fc + Net factor income from abroad
GNP mp = NDP fc + consumption of fixed capital + Net indirect tax [Net Indirect Taxes = Indirect tax – subsidy]
Expenditure method: Components are: 1. Government final consumption expenditure. 2. Private final consumption expenditure. 3. Net Export.
4. Gross domestic capital formation. (Gross investment expenditure)
Gross Domestic fixed+ Capital formation Thus, GDPmp = (1) + (2) + (3) + (4) GNPmp = GDPmp + NFIA NDPmp =GDPmp – Depriciation NNP fc = NDPmp - Net indirect taxes

One Mark questions. 1. When will the domestic income be greater than the national income? Ans: When the net factor income from abroad is negative.
2. What is national disposable income? Ans.It is the income, which is available to the whole economy for spending or disposal
NNP Mp + net current transfers from abroad = NDI 3. What must be added to domestic factor income to obtain national income? Ans. Net factor income from abroad. 4. Explain the meaning of non-market activities Ans. Non marketing activities refer to acquiring of many final goods and services not through regular market transactions. E.g. vegetable grown in the backyard of the house.
5. Define nominal GNP Ans. GNP measured in terms of current market prices is called nominal GNP.
6. Define Real GNP. Ans. GNP computed at constant prices (base year price) is called real GNP. 7. Meaning of real flow. Ans. It refers to the flow of goods and services between different sectors of the economy. Eg. Flow of factor services from household to firm and flow of goods and services from firm to household. 8. Define money flow. It refers to the flow of money between different sectors of the economy such as firm, household etc. Eg. Flow of factor income from firm to house hold and consumption expenditure from house hold to firm.
3- 4 Mark Questions 1. Distinguish between GDPMp and GNP FC
Ans. The difference between both arise due to (1) Net factor income from abroad. and 2) Net indirect taxes. In GDPMp Net factor income from abroad is not included but it includes net indirect taxes.
GNP FC = GDPMp + net factor income from abroad – net indirect taxes 2. Distinguish between personal income and private income Ans. Personal income: -It is the sum total of earned income and transfer incomes received by persons from all sources within and outside the country. Personal income = private income – corporate tax –corporate savings (undistributed profit) Private income consists of factor income and transfer income received from all sources by private sectors within and outside the country. 3. Distinguish between nominal GNP and real GNP Ans. Nominal GNP is measured at current prices. Since this aggregate measures the value of goods and services at current year prices, GNP will change when volume of product changes or price changes or when both changes. Real GNP is computed at the constant prices. Under real GNP, value is expressed in terms of prices prevailing in the base year. This measure takes only quantity changes. Real GNP is the indicator of real income level in the economy.
4. Explain the main steps involved in measuring national income through product method Ans.
a) Classify the producing units into industrial sectors like primary, secondary and tertiary sectors.
b) Estimate the net value added at the factor cost. c) Estimate value of output by sales + change in stock d) Estimate gross value added by value of output – intermediate consumption e) Deduct depreciation and net indirect tax from gross value added at market
price to arrive at net value added at factor cost = NDP Fc
f) Add net factor income received from abroad to NDP Fc to obtain NNP FC
which is national income
5...Explain the steps involved in calculation of national income through income method
a) Classify the producing enterprises into industrial sectors like primary, secondary and tertiary.
b) Estimate the following factor income paid out by the producing units in each sector i.e.
*Compensation of employees *Operating surplus *Mixed income of self employed
c) Take the sum of the factor income by all the industrial sectors to arrive at the NDP Fc
(Which is called domestic income) d) Add net factor income from abroad to the net domestic product at factor cost
to arrive at the net national product at factor cost. 6. Explain the main steps involved in measuring national income through expenditure method.
a) Classify the economic units incurring final expenditure into distant groups like households, government, firms etc.
b) .Estimate the following expenditure on final products by all economic units
Private final consumption expenditure
Government final consumption expenditure
Gross domestic capital formation
Net export (Sum total of above gives GDPMp)
c) Deduct depreciation, net indirect taxes to get NDP Fc
d) Add net factor income from abroad to NDP Fc to arrive at NNP FC. 7. What are the precautions to be taken while calculating national income through product method (value added method)
a) Avoid double counting of production, take only value added by each production unit.
b) The output produced for self-consumption to be included c) The sale & purchase of second hand goods should not be included. d) Value of intermediate consumption should not be included e) The value of services rendered in sales must be included.
8. Precautions to be taken while calculating national income through income method. a) Income from owner occupied house to be included. b) Wages & salaries in cash and kind both to be included. c) Transfer income should not be included d) Interest on loans taken for production only to be included. Interest on loan
taken for consumption expenditure is non-factor income and so not included. 9. Precautions to be taken while calculations N.I under expenditure method.
a) Avoid double counting of expenditure by not including expenditure on intermediate product
b) Transfer expenditure not to be included c) Expenditure on purchase of second hand goods not to be included.
10. Write down the limitations of using GDP as an index of welfare of a country 1) The national income figures give no indications of the population, skill and
resources of the country. A country may be having high national income but it may be consumed by the increasing population, so that the level of people‟s wellbeing or welfare standard of living remains low.
2) High N. I may be due to greater area of the country or due to the concentration of some resources in out particular country.
3) National income does not consider the level of prices of the country. People may be having income but may not be able to enjoy high standard of living due to high prices.
4) High N. I may be due to the large contribution made by a few industrialists 5) Level of unemployment is not taken into account. 6) National income does not care to reduce ecological degradation. Due to
excess of economic activity which leads to ecological degradation reduces the welfare of the people. Hence GNP and economic welfare are not positively related. Income in GNP does not bring about increase in economic welfare.
11. „Machine purchased is always a final good‟ do you agree? Give reason for your answer Whether machine is a final good or not depends on how it is being used (end use). If machine is bought by a household, then it is a final good. If machine is bought by a firm for its own use, then also it is a final good. If the machine is bought by a firm for resale then it is an intermediate good.
12. What is double counting? How can it be avoided? Counting the value of commodities at every stage of production more than one time is called double counting. It can be avoided by a) taking value added method in the calculation of the national income.
b) By taking the value of final commodity only while calculating N.I
1. State whether following is true or false. Give reason for your answer.
a) Capital formation is a flow True, because it is measured over a period of time. b) Bread is always a consumer good. False, it depends upon the end use of bread. When it is purchased by a household it is a consumer good. When purchased by restaurant for making sandwich, it is an intermediate (producer) good. c) Nominal GDP can never be less that real GDP False. Nominal GDP can be less than the prices in the base year. d) Gross domestic capital formation is always greater than gross fixed capital formation. False, gross domestic capital formation can be less than gross fixed capital formation if change in stock is negative.
2. Why are exports included in the estimation of domestic product by the expenditure method? Or Can the gross domestic product be greater than the gross national product? Explain Expenditure method estimates expenditure on domestic product i.e., expenditure on final goods and services produced within the economic territory of the country. It includes expenditure by residents and non residents both. Exports though
purchased by non residents are produced within the economic territory and therefore a part of domestic product. Domestic product can be greater than national product, if the factor income paid to the rest of the world is greater than the factor income received from the rest of the world i.e, when net factor income received from abroad is negative.
3. How will you treat the following while estimating domestic product of India? a) Rent received by resident Indian from his property in Singapore. No, it will not be included in domestic product as this income is earned outside the economic territory of India. b) Salaries if Indians working in Japanese Embassy in India. It will not be included in domestic product of India as embassy of Japan is not a part of economic territory of India. c) Profits earned by branch of American bank in India. Yes, it is included as part of domestic product since the branch of American bank is located within the economic territory of India. d) Salaries paid to Koreans working in the Indian embassy in Korea. Yes, it will be part of domestic product of India because the income is earned within the economic territory of India. Indian embassy in Korea is a part of economic territory of India. 4 How are the following treated in estimating national income from expenditure method? Give reason. a) Purchase of new car by a household: purchase of car is included in the national income because it is final consumption expenditure, which is part of national income. b) Purchase of raw material by purchase unit: purchase of raw material by purchase unit is not included in the national income because raw material is intermediate goods and intermediate goods and service are excluded from the national income. Purchase of raw material, if included in national income will result in double counting. c) Expenditure by the government on scholarship to student: It is not included in the national income because it is a transfer payment and no productive service is rendered by the student in exchange.
5 Are the following item included in the estimating a country„s national
income? Give reason. 1) free cloth given to workers: free cloth given to worker is a part of wages in kind i.e. compensation to employee such compensation to employee is paid for the productive services in the economy, it is included in the national income. 2) Commission paid to dealer in old car: commission paid to dealer in old car is included in the estimation of national income because it is the income of the dealer for his productive services to various parties. 3) Growing vegetable in a kitchen garden of the house: growing vegetable in a kitchen garden of the house amount to production, though not for sale for self-consumption. It is included in the national income because it adds to the production of goods.

Commercial Bank and the Central Bank
Q.1 Define Commercial Bank.
Ans. Commercial Bank is an institute which accepts deposits and advances loans with the view to earn profit.
Q.2 Explain the Functions of Commercial Bank.
Ans. Primary Function of Commercial Bank:
• Accepting Deposits: A bank accepts deposit from the public. People can deposits their cash balances.
• Advancing Loans: Banks advance loans mostly for the productive purposes,
against some collateral.
Secondary Functions:
• Overdraft Facilities
• Credit Creation
• Agent as advisor
• Draft facility provider
Q.3 What is Credit Multiplier?
Ans. It indicates the maximum credit that the commercial banks can create with their additional cash reserve.
Credit Multiplier = 1/CRR
Q.4 Define Money Multiplier.
Ans. Money multiplier or deposit multiplier measures the amount of money that the bank is able to create in the form of deposits with every unit of money it keeps as reserve.
Money Multiplier = 1/LRR
Q.5 What is the minimum value of money multiplier?
Ans. The minimum value of money multiplier is 1.
Q.6 Explain the process of Credit Creation by Commercial Bank.
Ans. The deposits held by banks are used for giving loans. However banks can not used the whole of deposits for lending.
It is legally compulsory for the banks to keep a certain minimum fraction of their deposits as resources. The friction is called legal reserve ratio (LRR) is fixed by the central bank.
Example: suppose initial deposits in is bank are rupees 1000 and LRR is 20%
It means, banks are required to keeps only Rs. 200 as cash reserves and free to lend Rs. 800.
This 800 will again come in the bank as deposit.
With new deposit of Rs.800, banks keep 20% as reserves and lend the balance Rs. 640 to other person, and so on…….
Initial deposit Round I Round II ………….. ………..... …………..
Deposits (in Rs.)
1000 800 640 ………….. …………… 5000
Loans (in Rs.)
800 640 512 …………… ………….. 4000
Cash Reserves (20%) 200 160 128 ………….. …………... 1000
Money Multiplier = 1/LRR= 1/0.2=5
Total Deposit = Initial Deposit X Money Multiplier
= 1000X5 = 5000
Q. 7 What is Cash Reserve Ratio?
Ans. This refers to the legally required cash reserves of the commercial banks with the central bank as a percentage of their total deposits.
Q.8 Define Statutory Liquidity Ratio (SLR).
Ans. This refers to liquid assets of the commercial banks which they are required to maintain as a minimum percentage of their total deposits.
Q.9 Dedfine Bank Rate.
Ans. It is the rate at which the central bank gives credit to the commercial banks.
Q.10 Define the Central Bank and explain its functions.
Ans. Central Bank is the apex institution which controls, operates, regulates and directs the entire monetary system of the country.
Functions of Central Bank:
• Issuing of Notes: Central bank of a country has the exclusive right of issuing
notes. This is called currency authority function of the central bank.
• Banker to the Government: Central bank is a banker, agent and financial
advisor to the government; it manages accounts of the government.
• Bankers Bank: It is an apex bank of all banks in the country. The central
bank has almost the same relation with other banks in the country as a commercial bank has with its customer.
• Lender of the last resort: When commercial bank finds trouble in their liquidity condition they directly contact to the central bank for assistance.
• Custodian of foreign exchange: Central bank is the custodian of nation‟s
foreign exchange reserves.
• Control of credit: It implies increase or decrease in the supply of money by
regulating the „creation of credit‟ by the commercial bank.
Q.11 How central bank controlled credit creation by the commercial banks?
Ans. The central bank adopts various measures to control the supply of money in the economy. It can be broadly classified in two categories:
• Quantitative Instruments:
• Bank Rate: It is the important instruments for Central bank to control
money supply in the economy. In order to increase or decrease money supply central bank increases or decreases bank rate.
• CRR: It is the important instruments for Central bank to control money supply in the economy. In order to increase or decrease money supply central bank increases or decreases bank rate.
• SLR: It is the important instruments for Central bank to control money supply in the economy. In order to increase or decrease money supply central bank increases or decreases bank rate.
• Open Market Operation: its refers to the sale and purchase of securities in the open market by the central bank. To increase money supply central bank purchases the securities from the commercial banks and vice versa.
• Qualitative Instruments:
• Margin Requirements: it is refers to the difference between the current value of the security offered for loan and the value of loan granted.in order to increase money supply central bank reduce the margin requirement and vice versa.
• Rationing of Credit: Rationing of credit refers to fixation of credit quotas for different business activities.
• Moral Suasion: Some times, the central banks makes the member banks agree through persuasion or pressure to follow its directives on the flow of credit.
Q.12 Calculate the value of money multiplier and the total deposits created if initial deposit is of rupees 500 crores and LRR is 10%.
Ans. Money multiplier = 1/LRR =1/10%=10
initial deposit is 500 crores
Total deposit= Initial deposit X money multiplier
= 500 X 10 = 5000 Crores.
Q.13 If total deposits created by commercial bank are rupees 12000 crores, LRR is 25% calculate initial deposit.
Ans. Money Multiplier = 1/LRR = 1/.25 = 4
Initial deposit = Total deposit/Money Multiplier
= 12000/4 = 3000 crores.
Q.14 If initial deposit is rupees 200 crores and total deposits is rupees 1600 crores, calculate LRR.
Ans. Money Multiplier = Total deposit/Initial deposits
= 1600/200 = 8
Money Multiplier = 1/LRR 8 = 1/LRR LRR = 1.25

SHORT QUESTION ANSWERS (3/4 MARKS) 1. Briefly explain the components of aggregate demand.
Aggregate demand is the total demand for goods and services in the economy. Aggregate demand in fact represents the total expenditure of goods and services in an economy. There are four components of aggregate demand (AD):
(i)Consumption (ii) investment (ii) government expenditure (iv)net export AD=C+I+G+(X-M)
2. Distinguish between MPC and MPS? Marginal propensity to consume is the ration of change in consumption to change on income. Symbolically, MPC = ∆c/∆Y Where ∆c= change in consumption
∆Y=change in income Marginal propensity to save is the ration of change in saving to change on income. Symbolically, MPS = ∆S/∆Y Where ∆S= change in saving
∆Y=change in income 3. What is consumption function? Draw the consumption schedule.
The relationship between consumption and income is called consumption function consumption function shows the relationship between consumption and income in terms of equation, it is written as under C = f(Y)
INCOME
0
CONSUMPTION (Rs. crores)
50 100 100 200 150 300 200 400 250 500 300
4. What is saving function? Draw the saving schedule.
The relationship between saving and income is called saving function. Saving function shows the relationship between saving and income in terms of equation, it is written as under S = f(Y)
Income 0 100 200 300 400 500
Saving(Rs. Crores) -50 0 50
100 150 200
5. What is meant by investment multiplier? Explain the relation between MPS and investment multiplier? Investment multiplier is defined as the ratio of change in income due to change in investment Symbolically,
Multiplier (k) =∆Y/∆I
Relationship between multiplier and MPS: the value of the multiplier varies inversely with MPS Higher the MPS, the lower will be the size of multiplier and lower the MPS, the larger will be the value of the multiplier. The relationship expressed as k=1/MPS FOR example, if MPS =. 10= 1/10, = 10.
6. Distinguish between Autonomous investment and induced investment . Autonomous investment: autonomous investment is not affected by the level of income of expected profitability. This is the investment made by the government with a view to increase the aggregate demand in an economy. The volume of autonomous investment is same at all the level of income.so AI curve is a horizontal straight line parallel to x axis. Induced investment: induced investment is made with the profit motive by the private sector. Induced investment is positively related with the level of income in an economy.at the higher level of income, consumption increases.
7. Briefly explain the meaning of involuntary unemployment and full employment? Involuntary unemployment: it refers to a situation when a person is unemployed at his own will and he does not want to work at the prevailing rate in the market. Full employment: full employment is the situation in which all those who are willing to work and are able to work at the existing wage rate, get the work
8. Explain the relationship between investment multiplier and marginal propensity to consume. The value of multiplier is determined by the MPC .Higher the MPC, greater the size of multiplier and vice versa. There is a direct relationship between multiplier and MPC Symbolically, k = 1/1-MPC
According to the Keynes, the value of MPC is always greater than zero but less than one accordingly, the value of multiplier would be greater than one but less than infinity. The value of multiplier thus varies from unity to infinity. Since we know that
MPC+MPS = 1 So we can write the investment multiplier.
K= 1/MPS So when MPC is equal to 1
K = 1/1-MPC= 1/1-1=1/0 =∞
It is clear that value of MPC is equal to 1 or MPS is zero then multiplier value will be ∞
K = 1/MPS =1/1=1 K=1
Problems of Excess Demand and Deficient Demand
1. Explain the concept of inflationary gap. Explain by diagram Inflationary gap may be defined as an excess of aggregate demand over aggregate supply at the full employment level. The inflationary gap results in the rise in general price level which is called inflation. The amount by which aggregate demand exceeds the level of aggregate production corresponding to full employment level of national income is known as inflationary gap.
2. What is fiscal policy? How is it used to correct Excess demand suggesting
two measures? Fiscal policy refers to the expenditure and taxation policy of the government. To correct excess demand two fiscal measures can be taken: (i)Reducing Govt Expenditure: There is a lot of non-essential and
non-productive expenditure which can be reduced to control excess demand. Govt can cut down its subsidies as on various items such as food, fertilizers, power supply export etc.
(ii)Increasing Taxes: when there is excess demand in in the economy „Govt should map up more resources from the public by increasing imposing taxes
3. Explain the meaning of deflationary gap. Deflationary gap is the situation when aggregate demand is less than aggregate supply at full employment level .It is the difference between actual level of aggregate demand and the level of aggregate demand required to achieve the full employment equilibrium.
4. Explain the role of CRR and Bank Rate to correct deficient demand. Cash reserve ratio is reduced to increase deficient demand. Bank rate is also reduced to increase demand.
5. Distinguish between fiscal policy and monetary policy to control money supply? Fiscal policy is undertaken by Govt but monetary policy is taken by Central bank of the country to reduce money supply.
Long Answer Questions (6 Marks)
1. Explain the determination of equilibrium level of income by aggregate demand and aggregate supply. According to Keynes, equilibrium level of income and output is determined at that point where Aggregate demand and Aggregate supply are equal to each other. AD= It is the summation of consumption demand and investment demand. Or AD= C+I. AS=It refers to the flow of goods and services in the economy in an accounting year. Diagram to be used for the said purpose.
2. Explain the equilibrium level of income with the saving and investment curve.
The equilibrium level of income is determined at the point where savings and investment are equal. S=I
Diagram to be used for the purpose.
3. Why should planned savings and planned investment be equal at equilibrium level of income? Explain with the help of diagram. Equilibrium GDP is stuck when S=I. S indicates withdrawal while I indicates injection into the circular flow, thus equilibrium GDP is achieved when withdrawal and injection exactly counterbalance each other.
Problems of Excess Demand and Deficient Demand(6 marks)
1. Explain the concept of deflationary gap. What is its impact on output, employment and price level in the economy? It is a situation when resources are not fully utilized and there is excess capacity in the economy. The economy drifting towards a situation of deflation. Accordingly deficiency of AD (compared to its full employment level) is often describe as a situation of deflationary Gap. Impact: (i)When AD fails to facilitate fuller utilization of factors and there is
excess capacity with the producers, they tend to build up unwanted inventory stock.
(ii)Passive inventory stock would forces the producers to plan lesser production. Implying in a cut in planned AS.
2. Explain the concept of inflationary gap. What is its impact on output, employment and price level in the economy? In a situation of excess demand, the level of output does not rise. Infact it cannot raise because factors are already full employed. Output level remain constant corresponding to the full employment level. Only price tend to rise.
IMPACT: (i)When AD increases beyond its full employment level, output remains
constant. But, the pressure on demand on the existing supply starts mounting up.
(ii)Mounting pressure on demand on the existing output causes a rise in the prices.
(iii)Excess demand also generates pressure of demand on existing resources, further it causes rise in the general price level.
3. What is fiscal policy? Explain the various fiscal measures used to control the situation of excess demand. fiscal policy refers to revenue and expenditure policy of the Government .it is also called budgetary policy of the Government. Measures to correct the situation of excess Demand – (i)The Government should step down its expenditure on public
programmer. (ii)The Government should increase the tax as well as new tax might be
introduced by the Government. 4. What is monetary policy? Suggest monetary measures to control the
situation of deficient demand. Monetary policy is that policy of the Government which corrects the situations of excess and deficient demand by regulating interest rate and availability of credit in the economy. Measure to control the situation of deficient Demand:
(i)
(ii)
(iii) (iv)

SHORT ANSWER TYPE QUESTIONS Marks (4) (BRIGHT STUDENTS)
Q 1.What is the of Revenue Deficit and what are its implications?
Ans- Revenue deficit: Revenue deficit is equal to the excess of total revenue expenditure over the total revenue receipts.
Revenue deficit= Revenue Expenditure –Revenue Receipts
Implications: (1) It indicates the inability of Govt. to meet its regular and recurring expenditure in the proposed budget.
(2) It implies that govt is dis- saving (3) It also implies that the govt. has to make Up this deficit from
capital Receipts (4)Use of capital Receipts for meeting the extra consumption
expenditure leads to an inflationary situation in the economy.
Q 2.What is the of Fiscal Deficit and what are its implications?
Ans-Fiscal deficit: . Fiscal deficit is equal to the excess of total expenditure over the sum of revenue receipts and capital receipts excluding borrowing.
Fiscal Deficit= Total Expenditure- Total Receipts Excluding Borrowings
Implications: (1)It creates a vicious circle of fiscal deficit and revenue deficit ,Wherein govt tax more loans to repay the earlier loans.
(2)It increases the money supply in the economy and creates inflationary pressure
(3)Govt . also borrows from the rest of the world which raises its dependences on the other countries.
(4)Borrowing increases the financial burden for future generation and this affects the future growth.
Q 3.What is the of Primary Deficit and what are its implications?
Ans-Primary deficit: Primary deficit is equal to fiscal deficit reduced by interest payments.
Primary Deficit=Fiscal Deficit- Interest Payments
Implications:(1)It indicates how much of the govt. borrowings are going to meet expenses other than the interest payment

BALANCE OF PAYMENT
What is Balance of Payments?
It is a systematic record of all economic transactions between the residents of a country & rest of the world during a financial year. In other words, it is a summary record of all international economic transactions of a resident country with the rest of the world during a given period of time.
Balance of Trade: It refers to the systematic record of visible items in a financial year. In other words, it is the value of imports and exports of commodities i.e. merchandise. If the exports exceed imports, the BOT is said to be favourable, and unfavourable in case of vice versa. Thus, Favourable BOT = Exports receipts > Import payments.
Difference between BOP & BOT
The term „Balance of Payments‟ refers to the account of both visible items & invisible items while „Balance of Trade‟ refers to the record of visible items only. BOT is only one of the components of BOP while the BOP is a wider concept & therefore offers a more comprehensive picture of economic transactions of a country with the rest of the world. Moreover, the BOT may be balanced, deficit or surplus, while BOP as a whole always remain balanced. BOT is a simple statements related to the foreign trade of the country while BOP presents a classified record of all receipts on account of goods exported, services rendered and capital received, and payments made on
account of goods imported, services rendered from, and capital transferred to abroad.
Items included in BOP account
1. Visible Items include all merchandise imports and exports i.e. the items which
are recorded at the port & made of some material. 2. Invisible Items include receipts & payments for the services viz. shipping,
banking, insurance, travel etc.; receipts and payments of income on foreign investments; interest on foreign loans & remittances of NRI‟s etc; govt‟s current expenditure in abroad viz. expenditure on embassies etc.; transfer payments & receipts.
3. Capital transfers include the capital receipts & capital expenditure of a resident country.
Structure of BOP: BOP account is categorized into Current Account & Capital Account.
BOP on Current Account refers to transactions related to goods, services, income on investments & unilateral transfers. BOP on current account reveals the net income of the country generated in abroad. Both visible & invisible items constitute the current account of BOP. It need not always be in balance. It may show a surplus or deficit. It represents the difference between payments & receipts of currently produced & consumed goods & services. A deficit in current account indicates lowering down the level of income, creating problem of the payments to the foreigners & have adverse impact on country‟s exchange reserves, & may increase external borrowings. The components of BOP on current account are:
1) Visible trade includes the export and import of the physical goods 2) Invisible items include cost of non-factor services; investment income, &
unilateral transfers. (i)The non-factor services include transportation, finance, tour & travel
etc. The services rendered by the resident country to the ROW are recorded on the credit side, while the services rendered by the foreigners for the resident country are recorded on the debit side.
(ii)Income on investment includes interest payments on foreign loans & credits, transfer of profits & miscellaneous for patents, royalties etc. The interest & dividend payments made by the foreigners are recorded on the credit side, and vice versa.
(iii)Unilateral Payments includes foreign gifts & grants, donations, military aid, technical assistance etc. These are also referred to as unrequired transfers. These refer to those receipts or payments which take place without getting anything in return. These transfers are further classified into Official & Private transfer payments. Official unilateral transfers are the foreign donations & aids, while Private transfers refer to the gifts & donations from foreign residents to the domestic residents & vice versa. Payments of these transfers are recorded as debit & receipts are recorded as credit.
Thus, the balance of visible trade, invisible trade & unilateral transfers is recorded as BOP on current account.
BOP on Capital Account: It refers to the international transactions in financial assets viz. bonds, equities, loans, bank account etc.; fixed plants & equipments, and direct investments. It is a record of those transactions which leads to change in assets or liability of the resident country. In other words, it is record of capital transactions i.e. the private & the official capital transfers as well as the banking capital flows. BOP on capital account deals with payments of debts and claims. The components of BOP on capital account are:
Private Capital Transactions which refer to those transactions which affect
assets or liabilities of the resident country i.e. the individuals, traders & other non-governmental agencies. It is further classified into short term & long term capital transactions. Short term capital includes purchase of short term securities, speculative purchase of foreign currencies, & cash balance held by foreigners. Long term private capital includes foreign direct investment (FDI), portfolio investment, long term loans, foreign currency deposits etc. Foreign direct investment refers to the purchase of assets in abroad & the power to control them. It includes the acquisition of a firm in the resident country by a non resident firm; transfer of firms from the parent company abroad to the subsidiary enterprise in the resident country. It also includes the import or export of capital goods. Portfolio investment refers to the purchase of an asset without any control over them. It includes the purchase of shares, govt‟s bonds, loans to firms or govt. of abroad. The notable feature of this transaction is that export of capital is a debit item as it causes outflow of foreign exchange & vice versa.
Official Capital Transactions refer to the transactions which affect assets & liabilities of the govt. It includes loans, repurchase & resale of securities sold to foreign residents, debt service, gold & foreign exchange reserves, & miscellaneous receipts & payments. Banking Capital Transactions includes movement in the external financial
assets and liabilities of those banks which are authorized to deal in the foreign exchange.
Difference between BOP on current account & capital account: The current account deals with the receipts & payments for those goods which are currently produced, while the capital account deals with debts & claims. Secondly, the BOP on current account has a direct influence on the level of income of a country, while the capital account influences the volume of assets of the country.
Other items in the BOP: There are certain items which do not form the part of current & capital account. These items are kept for balancing the BOP. These items are as follows:
I. Errors & Omissions are the balancing items in the BOP accounts which are used for correcting the BOP
as it is difficult to keep an accurate record of all the transactions which may be due to sample of transactions, dishonesty of traders, smuggling etc.
II. Official Reserve Transactions refer to those transactions which are carried out by the govt. and the
Central bank on behalf of govt. with regard to certain economic policy & their effect on BOP, & the exchange rates. It includes the Country‟s Official Reserve Assets & Foreign official Assets in the country.
The Official Reserves are held in the form of foreign currency or foreign
securities, gold & Special Drawing Rights (SDR) with the IMF. Reduction in these reserves implies purchase of foreign exchange which is taken as credit items in the BOP since it causes inflow of foreign exchange. On the contrary, an increase in these reserve assets is taken as a debit in the BOP as it causes outflow of foreign exchange.
The Foreign Official assets in the country are in the form of rupee reserves of foreign central banks. Increase in these rupee reserves of foreign banks is taken as a credit item as it causes inflow of foreign exchange in the resident country (India), while decrease in these reserves is taken as debit as it causes outflow of foreign exchange.
AUTONOMOUS & ACCOMODATING ITEMS
Items in the BOP account can be also classified into two categories viz.
Autonomous or above the line items and Accommodating or below the line items.
Autonomous items refer to those items which are taken with the motive of
profit maximization. These transactions are not related to the country‟s BOP position. It is, therefore, these items are called as autonomous items. These items are taken as first items before calculating deficit or surplus in BOP account, therefore these items are called as above the line items. If the receipts from autonomous items exceed the payments for autonomous items; the BOP is called to be as surplus, and vice versa. It implies that the resident country has net claims against the ROW. On the other hand, if the payments for these items exceed the receipts from these items, it implies that the ROW has some net claims against the resident country.
Accommodating items refer to those items which are undertaken by the govt. to keep the BOP balanced. These items are transacted when a country faces disequilibrium in the BOP. Through these transactions, the govt. or monetary authorities settle the deficit or surplus in the BOP.
Disequilibrium in the BOP: It refers to such a situation when the BOP of the country is deficit or surplus. In other words, it is a situation when the net balance of all receipts & payments is not zero. If the net balance is in (+), it is surplus; while the negative (-) balance is deficit. In both of the situation, the BOP is in disequilibrium.
Causes for disequilibrium in BOP: Disequilibrium in BOP may be due to the following reasons:
Economic Factors viz. Cyclical fluctuations, huge public expenditure on development projects, hike in inflation which induces large imports of essential goods, development of import substitutes, change in cost structure of the trading partner countries etc; Demonstration effect which implies the effect of developed countries on the lifestyle & consumption pattern of the less developed countries which leads to rise in imports; Political instability which may lead to large scale capital outflow; Social factors viz. changes in the social structure & norms which may affect the propensity to consume, comforts & exports; etc.
Measures to correct adverse BOP: Dear money policy, depreciation of the external value of domestic currency, devaluation of the currency, exchange control restrictions, tariff & import duties, fixing of import quotas, export promotion measures, import substitution etc.
