INTRODUCTION

QUESTIONS BASED ON HOTS WITH MODEL ANSWERS

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. What does a point below PPC indicate?

Ans. It shows inefficient/under-utilization of resources.

Q.6. What does slope of PPC show?

Ans. Negative slope of PPC shows that in order to produce more units of one good,

some units of the other good must be sacrificed.

Q.7. When allocation of resources is considered as inefficient?

Ans. Allocation of resources is considered as inefficient when economy performs

below the PPC curve.

SHORT ANSWER TYPE QUESTIONS: (3/4 Marks Each)

Q.1. 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.-3 Massive unemployment will shift the PPC to the left. Defend or refute.

Ans.- Production is drawn on the basis that the given resources are fully as well

as efficiently utilized. Massive unemployment is a situation when resources are

not fully utilized. Or it is a situation of under employment. It would only mean

that the economy is not operating on the PPC but some-what inside the PPC.

Therefore PPC will not shift to leftward.

Q.-3 What happens to the budget set if both the prices as well as the income

doubled?

Ans.- The budget set remains same.

Q.-4 A consumer consumes only two goods X and Y. At a consumption level of

these two goods, he finds that the ratio of marginal utility of price in case

of X is higher than in case of Y. Explain the reaction of the consumer.

Ans.- The consumer will increase the consumption of good-X and will decrease

the consumption of good-Y.

Q.-5 Does a fall in income have the same effect on the demand for the given

commodity?

Ans.- No, it will depend upon the nature of the good. If good is normal then its

demand will increase and if the good is inferior then its demand will decrease

Q.-6 There is train and bus service between New Delhi and Jaipur. Suppose

that the train fare between the two cities comes down. How will this affect

demand curve for bus travel between the two cities?

Ans.- As train and bus service are substitute to each-other, the demand curve for

bus service between the two cities will shift leftward to the initial demand curve

of bus service

Q.-7 Determine how the following changes (or shifts) will affect market

demand curve for a product.

(a) A new steel plant comes up in Jharkhand people who were previously

unemployed in the area are now employed. How will this affect the demand

for colour T.V. and Black and White T.V. in the region?

(b) In order to encourage tourism in Goa. The Government of India suggests

Indian Airlines to reduce air fare to Goa from the four major cities of

Chennai, Kolkata, Mumbai and New Delhi. If the Indian Airlines reduces

the fare to Goa, How will this affect the market demand curve for air

travel to Goa?

(c) There are train and bus services between New Delhi and Jaipur. Suppose

that the train fare between the two cities comes down. How will this affect

demand curve for bus travel between the two cities?

Ans: (a) There will be rightward shift in market demand curve for colour and Black

and White T.V. This is because of increase of income of the people due to

employment in the new steel plant.

(b) The demand for travel to Goa will expand in response to reduction in the air fare.

However, this will be reflected by a movement along the demand curve. There

will be no shifts in the demand curve.

(c) As train fare comes down the demand for bus travel will reduce. Demand curve

for the bus travel will shift to the left showing less demand at the same price.

Q 8. If a good can be used for many purposes, the demand for it will be elastic.

Why?

Ans: If a good can be used for many purposes , the demand for it will be more

elastic because with a decrease in its price it is put to several uses and with a

rise in its price it is withdrawn from its many existing uses. So that, there is a

considerable change in demand in response to some change in price.

Q 9. “If a product price increases, a family‟s spending on the product has to

increase.” Defend or refute.

Ans: When product price increases, expenditure on the commodity will not increase

in the situation when Ed>1 (elasticity of demand is greater than unity). It will

increase only in situation when Ed<1. In a situation when Ed=1. Expenditure

will remain constant, even when prices rise.

Q 10. Suppose there are 30 consumers for a good, having identical demand

function: d(p) =10-3P for any price less than or equal to 10/3 and d(p)=0

for any price greater than 10/3. Write the market demand function.

Ans: Market demand function is simply a horizontal summation of individual

demand functions. Since demand function for all the 30 consumers is identical,

we can write market demand simply as „individual demand function

multiplying by a factor of 30‟. Thus:

Individual demand function :

D(p)= 10-3P

Market demand function:

Md(p)=10 x 30 – 3 (30)P

= 300-90 P.

Q.11 How would you comment on the elasticity of demand when 8% decrease

in price of a commodity causes 2% increase in expenditure of the

commodity?

Ans: Elasticity of demand must be greater than unity (implying a situation of elastic

demand) when expenditure on the commodity responds inversely to any change

in price of the commodity.

Q12. A dentist was charging Rs.300 For a standard cleaning job and per

month it used to generate TR is equal to Rs. 30,000. She has since last month

increased the price of dental cleaning to Rs.350. As a result fewer customers are

now coming for dental cleaning, but the TR is now Rs. 33,250 .From this, what

can we conclude about the elasticity of demand for such a dental service?

Ans. PRICE TOTAL EXPENDITURE (Rs.)

300 30,000

350 33,250

When price increases, total expenditure also increases. So elasticity is less than 1.

Q. 13. The elasticity of demand for X is twice the elasticity of demand for Y.

Price of X falls by 5% and Price of Y rises by 5% . What will be the % change

in the quantity demanded of X and Y?

Ans. Suppose elasticity of demand for Y = 1 , and

elasticity of demand for X will be = 2

So, % decrease in qt. demanded of Y will be 5% , because price rises by

5%, and

% increase in qt. demanded of X will be 10% , because price falls by 5% .

Q.14 If prices of salt and cigarettes, both rises by 10% , will the qt. demanded

of both goods affected in an equal manner?

Ans. No, because the nature of the two goods is different. Salt , a necessary good,

will have constant consumption and marginal consumers will reduce the

consumption of cigarettes , which is non-essential.

Q 15. Given eD = - 0.02, and percentage increase in price = 20%, find change in

expenditure on the commodity.



www.studiesto

Implying that expenditure on the commodity increses by 15.2% owing to increase

the commodity by 20% . Which is why ed is less than 1.

less of commodity X to reach the equilibrium position. Is it right or

wrong?



www.studiesto

Ans.- Wrong. Because in that situation consumer should increase consumption of

good-X so that the ration of MUX to its price may become equal to the ratio of

MUY to its price.

Q. 17 Law of diminishing marginal utility will operate even if consumption

takes place in intervals. Defend or refute.

Ans.- No, the of diminishing marginal utility will operate even if consumption takes

place in intervals. Because it is based on the assumption that consumption is

taking place in continuation

Q. 18 What changes will take place in TU, when: (i) MU curv remain above the

X-axis, (ii) MU curve touches the X-axis, (iii) MU curve lies below the X-

axis.

Ans.- (i) TU increases at decreasing rate. (ii) TU becomes maximum. And (iii) TU

starts to decline

Q. 19 A good may be an inferior good for one consumer and normal for another

consumer. Defend or refute.

Ans.- Yes it is right. A good may be inferior for a higher income person and the

same good may be a superior good for a low income person

UNIT – III

PRODUCER BEHAVIOUR AND SUPPLY


Q.1. What happens to MPP when TPP increases at decreasing rate?

Ans. MPP falls but remains positive.

Q.2. As the variable input is increased by one unit, total output falls. What

would you say about of marginal productivity labour?

Ans. Marginal productivity of labour is negative.

Q.3. Why is MC curve in short run U-shaped?

Ans. MC Curve in short run is U-shaped due to operation of the law of returns to a

factor.

Q.4. Why does fixed cost not influence marginal cost?

Ans. Because marginal cost do not include fixed cost.

Q.5. When a seller sells his entire output at a fixed price, what will be the

shape of AR & MR curves?

Ans. Both AR & MR are equal and coincide with each other on a horizontal line.

Q.9. What happens to TPP when marginal productivity of variable input is

negative?

Ans. TPP falls.

Q.10. When is TPP maximum in relation to MPP?

Ans. When MPP is zero.

Q.11. What happens to MPP when TPP is declining?

Ans. MPP declines and remains negative.

Q.12. How does fall in MPP affect TPP?

Ans. TPP increases at decreasing rate.

Q.13. What effect does an increase in input price have on the supply curve?

Ans. The supply curve will shift towards left-hand side.

Q.14. Why does average cost fall as output rises?

Ans. AC falls due to operation of the law of increasing returns to a factor as output

rises.

Q15. Does fixed cost affect marginal cost? Give the answer with reason.

Ans. No, because fixed cost is not subject to change and it is not considered while

calculating MC.

Q.16. What would be the effect of increase in the output on the TFC?

Ans. There would not be any effect of increase in the output on the TFC, It will be

constant at different levels of production.

Q.17. If marginal revenue falls, will total revenue fall?

Ans. It may fall when MR falls and becomes negative. If MR falls but remains

positive then TR may increase with diminishing rate.

Q.18. What is the price elasticity of supply of a commodity whose straight line

supply curve passes through the origin forming an angle of 25º?

Ans. Price elasticity of supply will be equal to one when a straight line supply

curve passes through the origin; angle does not matter anything.

Q. 19. Can MC be equal to TVC?

Ans.- Yes MC may be equal to TVC at output level one.

Q. 20 Why does the minimum point of AC curve fall towards right of AVC

curve?

Ans.- Because AC is sum total of AVC and AFC.

Q.21. The two inversely S-shaped short run cost curves are parallel to each

other and maintain a constant distance of Rs. 50. What is indicated by Rs.

50? Also identify the two inversely S-shaped short run cost curves.

Ans.- Rs. 50 is TFC. And two inversely S-shaped cost curves are TVC and TC

respectively.

Q. 22. The equality of MC and MR is a condition necessary for equilibrium, but

it is not by itself sufficient to ensure the attainment of producer‟s

equilibrium. Comment.

Ans.- Yes. For consumers equilibrium it is also essential that after the equilibrium

level of production MC should be greater than MR. Other-wise there will be

an incentive to increase the output in order to maximize the profit.

Q. 23. Ram produces both Jeans and Shirts. How will an increase in the price of

Jeans affect the supply curve of Shirts?

Ans.- An increase in the price of Jeans will decrease the supply of Shirts, because

now it will be profitable to the producer to produce and sell more of Jeans

instead of Shirts, as it has become expensive.

Q. 24. Will a firm stop production at break-even point in short run? Why?

Ans.- No, firm will not stop the production at break-even point because that firm has

given best employment to its factors of production.


Q.1. Why is more of a commodity supplied only at a higher price?

Ans.- Because increase in production leads to decrease in returns to a factor. That in

turn leads to increase in cost. That is why more of a commodity supplied only

at a higher price

Q. 2. Suppose the functions of demand and supply curves of a commodity are

given by: qD = 100-p

qS = 60 + p for p≥ 15

= 0 for 0≤p<15



www.studiesto

(i) What does p =15 indicate?

(ii) Find the equilibrium price and equilibrium quantity.

(iii) Whether the given commodity comes under the category of viable

industry.

(iv) Calculate market demand and supply at price of Rs. 25 and Rs. 10.

Show that at price of Rs. 25, there is excess supply and at price of Rs.

10, there is excess demand.

Ans.-

(i) P=15 indicates that the minimum average cost of the firm is Rs. 15 and

firm will not supply the commodity for any price less than Rs. 15

(ii) Equilibrium Price = Rs. 20 and equilibrium quantity = 80 units

(iii) Yes, the given commodity comes under the category of viable industry as

there is some price, at which supply and demand happens to coincide.

(iv) At price Rs. 25 market demand = 75 units and market supply = 85 units.

Therefore there will be excess supply of 10 units

And at price of Rs. 10 market demand = 90 units and market supply = 70

units. Therefore there will be excess demand of 20 units.

Q. 3. There are three different supply curves passing through the origin. A

curve makes an angel of 60o. Curve B makes an angel of 45

o and curve C

makes an angel of 30o. What will be the price elasticity of curve A, B and

C?

Ans.- Price elasticity of supply of good will be equal to one if supply curve is

passing through the origin point, irrespective of the angel made by it with the

origin.

Q. 4. Why should MC curve cut MR curve from below to achieve producer‟s

equilibrium?

Ans.- Because after equilibrium level of output, marginal cost should become

greater than the marginal revenue. Other-wise there will be an incentive to

increase the output in order to maximize the profit.

Q. 5. The gap between AC and AVC keeps on decreasing with rise in output,

but they never meet each other. Comment.

Ans.- Yes it is right statement. Because the gap between AC and AVC is equal to

AFC which goes on diminish as output increases. Since TFC is fixed at all

levels of output, AFC goes on diminish as output increases

Q. 6. If TVC=0, TC is also zero. Is it true or falls? Give reason for your answer.

Ans.- It is falls. Because in short TC = TFC + TVC. Therefore in short run TC will

be some-thing positive even if TVC=0. But in long run TC = TVC. Therefore

in long run TC will be zero if TVC=0.

Q. 7. Why increasing MP not sustainable?

Ans. Decrasing MP set in due to following reasons:-

1. Fixity of the factor: As more and more units of the variable factor continue

to be combined with the fixed factor, the later gets over-utilized.

2. Imperfect Substitution among Factor: Beyond a certain limit, factors of

production cannot be substitute for one another e.g. more and more of

labour cannot be continuously used in place of additional capital.

Q. 8. Why MC cuts AC at its minimum?

Ans. because (i) When MC < AC, AC falls.

(ii) When MC = AC, AC is minimum.

(iii) When MC > AC, AC rises.

(iv) MC falls & rises faster than AC.

(v) Both are obtained from TC.

Q. 9. How do changes in MR affect TR?

Ans. i) If MR increases, TR increases at increasing rate.

ii) If MR is constant, TR increases at constant rate.

ii) IF MR falls, TR increases at diminishing rate.

Q.10. What is MR? How is it related to AR?

Ans. MR refers to the change in TR due to sale of an additional unit.

Relation –

(i) If AR (Price) is constant, MR = AR

(ii) If AR (Price) falls, MR < AR.

(iii) If AR (Price) rises, MR > AR.

Q. 11. What will be the price elasticity of supply if the supply curve is a

positively sloped straight line?

Ans. Es = 1 if the curve starts from the origin point.

Es> 1 if the curve starts from the y-axis and

E<1 if the curve starts from the x-axis.

Q. 12. State the relation between marginal revenue and average revenue when a

firm:

(i) is able to sell more quantity of output at the same price.

(ii) is able to sell more quantity of output only by lowering the price.

Ans. Marginal revenue is the addition to total revenue from producing one more

unit of output.

SHORT ANSWER TYPE QUESTIONS: - (3 /4 Marks Each)

Q 1. Explain how the efficiency may increase if two firms merge?

Ans: When the two firms merge, their combined efficiency is expected to improve

owing to:

(A) Increase in the scale of output and the consequent economies of scale.

(B) Better division of labour and specialization; and

(C) Use of better technology, saving the cost of production.

Q 2. Why is the demand curve facing a monopolistically competitive firm likely

to be very elastic?

Ans: It is because the products produced by the monopolistically competitive firms

are close substitutes to each other. If products are close substitutes to each

other the elasticity of demand is high, which is what makes the firm‟s demand

curve(under monopolistic competition) very elastic.

Q 3. Why is the demand curve facing a firm perfectly elastic under perfect

competition but less than perfectly elastic under monopolistic

competition?

Ans. The demand curve under perfect competition is perfectly elastic. Perfectly

elastic demand curve means any quantity can be sold only at a given price.

Under perfect competition, the price of the product is determined by the

industry by the forces of demand and supply and the firm has no option but to

accept it. Uniform price prevails because all firms are selling a homogeneous

product. A firm cannot influence or alter the price. Implying that a firm can

sell any quantity at the given price. Therefore, the demand curve will be a

straight line parallel to the X-axis as shown in Fig. ; which is perfectly elastic,

showing Ed=infinity

The demand curve under monopolistic competition is less than perfectly

elastic. It means more can be sold only at lower price. Under monopolistic

competition, the seller sells a differentiated product, so he exercises partial

control over price. But he can sell more only by lowering the price; certainly

not at the existing price.

This is what makes the demand curve less than perfectly elastic.

Q 4. Which features of monopolistic competition are monopolist in nature?

Ans. (i) Product differentiation

(ii) Control over price

(iii) Downward sloping demand curve

Q 5. How does an increase in the price of a substitute good in consumption

affect the equilibrium price?

Ans: With increase in the price of the substitute good, the equilibrium price of the

concerned good will increase owing to shift in demand curve to the right.

Q 6. „Changes in both demand any supply of a commodity may or may not

affect its equilibrium price.‟ Explain.

Ans: If the demand and supply of a commodity change equally, and in the same

direction there will be no effect on its price. On the other hand, an unequal

change in demand and supply will affect equilibrium price. When demand

increases more than supply, equilibrium price will rise. On the other hand,

when supply increases more than demand, equilibrium price will fall.

Q 7. When will the equilibrium price of a commodity not change even if its

demand and supply both increase? Explain with the help of a diagram.

Ans. If both increases equally.

Q 8. A severe drought results in a drastic fall in the output of wheat. Analyze

how will it affect the market price of wheat?

Ans: As a result of severe drought, the output of wheat is reduced. It means the

supply of wheat in the market will reduce, causing a shift of supply curve to

the left. Accordingly, market price of wheat will increase.

Q 9. Suppose the demand for jeans increases. At the same time, because of an

increase in price of cotton, the supply of jeans decreases. How will it

affect the price and quantity sold of jeans?

Ans: Increase in market demand for jeans along with a decrease in the supply of

jeans should raise the price of jeans and the quantity sold will decline.

Q 10. China is a big manufacturer of technology of telephone instruments. It

has recently become a member of W.T.O., which means it can sell its

products in other member countries like India. Suppose that it does

export a large number of telephone instruments to India:

(A) How will it affect the price and quantity sold of telephone instruments

in India?

(B) Suppose that the demand for telephone instruments is relatively

elastic. How will it affect India‟s total expenditure on telephone

instruments?

Ans: (A) As a result of large export of telephone instruments by Chine to India, the

market supply of telephone instruments increases. It reduces the price of

telephone instruments while the quantity sold will increase.

(B) If the demand for telephone instruments is relatively elastic, reduction in

price should increase total expenditure on telephone instruments in India.

Q 11. Mrs. Ramgopal says that economists say inconsistent things: as price

falls, demand rises, but as demand rises, price rises. Defend or refute.

Ans: The statement of Mrs. Ramgopal that “as price falls, demand rises, but as

demand rises, price rises”, can be defended. The first part of the statement i.e.

as price falls demand rises is the general behavior of the consumer in the

market. This is simply a forward movement along a demand curve. Demand

changes due to change in the price of the commodity. But, there may also be

situation when increase in demand leads to increase in price. When the supply

of the commodity remains unchanged. And demand increases (due to factors

other than price such as increase in income of the consumer or change in taste

preference of the consumer.) The demand curve shifts upward and it raises the

market price. Fig. illustrates the two situations:

Q 12. Answer all the questions in terms of shifts in or movements along the

demand and supply curves.

(A) In 2001, the Supreme Court of India banned smoking in public

places. How is this likely to affect the average price of cigarettes and the

quantity sold?

(B) New discoveries of oil reduce the price of petrol and diesel. Consider

their effects on the market for new cars.

(C) New environmental regulations require the drug industry to use a

more environment friendly technology whose running cost are higher but

which discharges less chemicals than before. How would it affect the price

of drug?

Ans: (A) A ban on cigarette smoking in public places should cause a backward shift

in demand curve. Consequently average price of cigarettes should fall. Fall in

average price of cigarette should cause a fall in quantity sold.

(B) New discoveries of oil reducing the price of petrol/diesel should imply

increase in demand for cars (in terms of shift in demand curve to the right), as

cars and petrol/diesel are complementary goods.

(C) Due to the use of costlier (environment friendly) technology, supply curve

of drug will shift to the left, causing a rise in the price of drug.

Q 13. In a state of equilibrium, price greater than MC is ruled out for a

perfectly competitive firm. Show diagrammatically.

Ans: Fig illustrates how prices greater than MC is ruled out for a perfectly

competitive firm in a state of equilibrium. Equality between price (AR) and

MC is struck at point Q where all the conditions of equilibrium are satisfied.

OL is the equilibrium level of output. Suppose the firm decides to produce



www.studiesto

day.com

25

OL1 output where AR(=L1Q1)>MC(=L1T1). As a consequence of shifting

from Q to Q1; loss of TR=Q1L1LQ, while the TC is saved to the tune of Q1TQ.

Evidently, reduction in TC (=Q1TQ) is only a part of reduction in

TR(=Q1L1LQ). Implying that the differential between TR and TC(= profit)

would reduce in case the firm shifts from Q to Q1 Profit is maximized only at

point Q where price = MC.

Q 14. In a state of equilibrium, price lesser than MC is ruled out for a perfectly

competitive firm. Show diagrammatically.(Question for practice)

Q 15. What is firm‟s supply curve in the short run, operating under perfect

competition?

Ans: It is MC curve of the firm starting from a point where MC=AVC (minimum).

In Figure, short period supply curve of the firm is MC curve starting from point Q

where AR= AVC (minimum).

Q.16 In which market situation, the influence of an individual seller is zero?



www.studiesto

day.com

26

Ans. In the Perfectly Competitive market situation.

Q.17 How is a single buyer a price taker in perfect competition?

Ans. A single buyer‟s share in total market demand is so significant that the buyer

cannot influence the market price on his own by changing his demand.

Q.18 Normal profit means zero economic profit. Why?

Ans. Suppose the existing firms are earning above normal profits. Attracted by the

positive profits, the new firms enter the industry .The market supply increases

and the price comes down. New firms continue to enter and the price

continues to fall till economic profits are reduced to zero.

In case of losses, firms start leaving the industry, supply falls and prices

starts going up and all this continues till losses are wiped out. Remaining

firms in the industry then once again earn just normal profits / zero profit.

Q. 19. Why does there are few firms in oligopoly market?

Ans.- There are only few firms in oligopoly market because there are some

restrictions on the entry of firms in the market. Which are inter-dependence of

firms, big requirements of funds, great competition among the firms. The only

firms which can break these restrictions are able to enter the market.

Q. 20. Does a monopolist has full control over the price?

Ans. No, because price is determined by the forces of demand and supply . a

monopolist controls only the supply side and demand side remain

uncontrolled.

29

Ans. (i) It should be included in NI because it is a part of the compensation of

employees (salary in kind).

(ii) It is included in NI because it is a part of the final consumption expenditure

on domestic product.

(iii) It should be included in NI because it is an addition to the capital stock of

the production unit.

(iv) It should not be included in NI because it is a compulsory transfer

payment and paid from past savings of the tax payers.

Q.6. Is net export a part of NFIA? Explain.

Ans. No, it is not.Net export, the difference between export and import (X- M), is

a part of expenditure on domestic product. While NFIA is the difference

between income earned from abroad by the normal residents of a country and

income earned by non-residents in the domestic territory of that country. It is

not included in the domestic product rather it is a component of NI. Therefore

both are different concepts.

Q.7 Should we treat subsidy as transfer payment?

Ans. No, value addition has already accrued. In fact, subsidies tend to lower the

market value of the good produced .Accordingly, these are added to the

market price to make it equal to the factor cost . Subsidies are a part of NNP

FC which is why these are deducted from factor cost to equate it with market

price.

Q.2. Why are exports included in the estimation of domestic product by the

expenditure method? Can gross domestic product be greater than gross

national product? Explain.(4+2)

Ans. 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 factor income

paid to the rest of the world is greater than the factor income received from

the rest of the world is i.e. when net-factor income received from abroad is

negative.

(viii) Wages and salaries 3500

(ix) Interest payment 1000

(x) Dividend 1500

(xi) Corporate gain tax 300

(xii) Undistributed profit 200

Solution: -

GDPMP = Sales + Increase in the stock - Purchase of raw materials - Purchase of fuel

and power.

= 10,000 + 1000 -1650 -850

= 11,000 -2500

= 8500 Crores.

Net Value Added at factor cost = Sales + Increase in the stock - Purchase of raw

materials –

Purchase of fuel and power - Consumption of fixed capital - Net

indirect tax.

= 10,000 + 1000 - 1650 - 850 - 500 – 800

= 11,000 – 3800

= 7200 Crores.

Income generated = Rent + Wages and salaries + Interest + Dividend + Corporate

gain tax + Undistributed profit.

= 700 + 3500 + 1000 + 1500 + 300 + 200

= 7200 Crores.

Hence it is proved that Net Value Added at factor cost = Income Generated

UNIT VII

DETERMINATION OF INCOME AND EMPLOYMENT


Q. 1 Can consumption exceed income? If yes, what is the saving then?

Ans. Yes, when income is zero or less than subsistence level of

consumption . Saving is –ve.

Q.2 How much new income will be generated in an economy with an

increase in investment by Rs. 200 and when two-third of rise in

income spent on consumption.

Ans. 600 Rs .

Q.3 Why can the value of MPC be not greater than 1?

Ans. It is because change in consumption can never be greater than change in

income.

Q.4 Does an excess of AD over AS always imply a situation of inflationary gap?

Ans. No. Inflationary gap occurs only when AD>AS corresponding to full

employment level of employment.

Q.5 What happens in an economy, when credit availability is restricted and

credit is made costlier?

Ans. Aggregate demands falls


Q.1 What happens if AD>AS prior to full employment level of employment?

Ans. It is a state of disequilibrium in economics. When AD>AS , producers have to

cater to demand out of their existing stock of goods , implying that the desired level



www.studiesto

day.com

38

of stocks will decrease. It implies greater production & therefore there is increase in

AS .This process continues till equilibrium is struck between AD and AS.

Q.2 In poor countries like India , people spend a high percentage of their

income so that APC and MPC are high . Yet , value of multiplier is low . Why?

Ans. Working of the multiplier process is based on one fundamental assumption:

that there exists, excess capacity in the economy , so that whenever consumption

expenditure rises (implying increase in demand ) there is a corresponding increase in

production (implying increase in income ) . But poor countries like India, lack in

production capacity. Accordingly, whenever demand increases (in terms of increase

in consumption expenditure), there is increasing pressure of demand on the existing

output (implying inflation or rise in prices) rather than the increase in output or

loan to such a bank against approved securities. As a lender of the last resort, central

bank exercises control over the entire banking system of the country.

Bank B and Bank B receives a cheque of Rs. 15000 drawn on Bank A. The most

convenient method of settling or clearing their mutual claims is that Bank A should

issue a cheque amounting to Rs 5000 in favour of Bank B, drawn on central Bank.

As a result of this transference, a sum of Rs 5000 will be debited to the account of

Bank A and credited to the account of B. There is not need of cash transactions

between the banks concerned. It facilitates cash transaction across the entire banking

system, it also reduces requirement of cash reserves of the commercial banks.
