Suggested Answers Economics (MB141) : April 2004
1. Answer : (b) Reason : I. When a local rent control ordinance establishes a ceiling of Rs.3500 per room, which is
much higher than the equilibrium rent, it will not affect the equilibrium rent and quantity of rooms available.
II. If the government announces a minimum support price of Rs.9, which is more than the equilibrium price of wheat, the support price reduces quantity demanded and increases quantity supplied. This will result in a surplus in the market.
III. When a minimum wage is enforced which is below the prevailing market equilibrium wage of Rs.100 per day, it will have no effect on labor hours. (a) Is not the answer because in I above (b) Is the answer because there is a surplus in the market in II above (c) Is not the answer because there is a surplus in II, but no surplus in I above (d) Is not the answer because there is no surplus in I and III above (e) Is not the answer because there is a surplus in the market II but no surplus in III above.

2. Answer : (b) Reason : The law of demand is directly derived from the law of diminishing marginal utility. When the
price of the good falls, the consumer buys more of the good so as to equate the marginal utility to the lower price. The downward sloping marginal utility curve can be converted into the downward sloping demand curve. (a) Is not the answer because indifference curve doesn’t resemble the demand curve of a
consumer. An indifference curve depicts the various alternative combinations of the goods, which provide same level of satisfaction to the consumer.
(b) Is the answer because marginal utility curve resembles the demand curve of a consumer. (c) Is not the answer because budget line is not same as the demand curve of a consumer. Budget
line represents all the combinations of the two commodities, which the consumer can buy by spending his entire income for the given prices of the two commodities.
(d) Is not the answer because total utility curve is not same as the demand curve of a consumer. Total utility curve is a curve representing the sum of all the utilities derived from the total number of units consumed.
(e) Is not the answer because average utility curve is not same as the demand curve of a consumer.
< TOP >
3. Answer : (c) Reason : Consumer surplus is the excess of the price that a consumer is willing to pay for the commodity
over and above what he actually pays for it. (a) Is not the answer because Parma is offered a job below the price what she expected. So, this
doesn’t reflect the consumer surplus. (b) Is not the answer because Raju refused to buy the same shirt at Rs.180,but he pays for the
same shirt a sale price of Rs.150. So, this doesn’t reflect the consumer surplus. (c) Is the answer because Tendulkar is ready to pay Rs.8 for a pepsi, but he gets it free. This is a
case of consumer surplus. (d) Is not the answer because the price of the burgers has reduced by 50 percent. This is not a
case of consumer surplus. (e) Is not the answer because Rajesh has a marginal cost of Rs. 500 for a unit of output and sells
that unit at Rs.600.This is not the excess of the price that a consumer is willing to pay for the commodity over and above, what he actually pays for it. So this is not a case for a consumer surplus.

4. Answer : (c) Reason : When the prices of consumer electronics have dropped, while consumer spending on these
electronic goods has increased, the demand for consumer electronic goods is relatively elastic. In this case the percentage change in quantity demanded is greater than the percentage change in price
< TOP >
and the value of price elasticity of demand will be greater than one. (a) Is not the answer because in case of a perfectly inelastic demand, if the price of a good
decreases, consumer spending on these goods has to be decreased. (b) Is not the answer because in case of a relatively inelastic demand, if the price of a good
decreases, consumer spending on these goods has to be decreased. (c) Is the answer because in case of a relatively elastic demand, if the price of a good decreases,
consumer spending on these goods has to be increased. (d) Is not the answer because in case of a unitary inelastic demand, if the price of a good
decreases, consumer spending on these goods remain constant. (e) Is not the answer because in case of a perfectly elastic demand, if the price of a good
decreases, consumer spending on these goods undetermined.
5. Answer : (d) Reason : Since Coke and Pepsi are perfect substitutes, (i.e. gives same amount of satisfaction) Ramesh
would consume the one that is available at a cheaper price. With the increase of price of Pepsi, Coke becomes cheaper. Hence, Ramesh would spend his entire income on Coke. Hence the correct answer is (d).
< TOP >
6. Answer : (b) Reason : When the price of good X doubles, the consumer can buy less of the good X with the given
income, but can buy same quantity of another good. Hence, the the Y-intercept remains the same but the X-intercept falls.
(a) Is not the answer because the budget line will not shift towards left (b) Is the answer because the Y-intercept remains the same but the X-intercept falls (c) Is not the answer because the Y-intercept remains the same but the X-intercept does not increase (d) Is not the answer because the budget line will not shift towards right (e) Is not the answer because the budget line will be affected.
< TOP >
7. Answer : (b) Reason : A consumer can maximize total utility (TU) when
= = - - - - - = . This equilibrium condition says that to maximize Total Utility, Marginal Utility for the last rupee spent on all the goods should be equal. (a) The consumer may not maximize Total Utility as price of all the goods may not be equal. (b) The consumer maximize Total Utility as Marginal Utility for the last rupee spent on all goods
is equal. (c) Though elasticity of demand is same for all the goods this does not ensure maximum Total
Utility as the above condition is not satisfied. (d) This may not maximize Total Utility as irrespective of the price paid, Total Utility of every
good is same. Further, this does not satisfy the above utility maximizing condition. (e) Budget may not permit the consumer to reach the state of maximum Total Utility for each
and every good at which point Marginal Utility is equal to zero.

8. Answer : (d) Reason : A combination of inputs to the right of the cost line indicates that it is a point above the cost
function which cannot be reached with the given budget. Hence, the correct answer is (d). (a) Is not the answer because the combination of capital and labor lies to the right of the firm’s cost line
is not undesirable. (b) Is not the answer because the combination of capital and labor lies to the right of the firm’s cost line
is not concerned whether the combination is efficient or not, given the budget. (c) Is not the answer because the combination of capital and labor lies to the right of the firm’s cost line
is not concerned whether the combination is inefficient or not, given the budget (d) Is the answer because the combination of capital and labor lies to the right of the firm’s cost line is
unattainable, given the budget. The firm’s cannot hire the combination of capital and labor, given the budget.
(e) Is not the answer because the combination of capital and labor are not inferior to the points within
< TOP >
the constraint in terms of production, but it is not attainable.
9. Answer : (c) Reason : The law of diminishing returns states that by employing more units of some factors of production
to work with one or more fixed factors, the total product will increase at an increasing rate, then at a constant rate and finally at a diminishing rate. (a) Is not the answer because the law of diminishing returns holds good when all labors are
equally efficient i.e. labor are homogeneous. (b) Is not the answer because the law of diminishing returns is relevant only when the time period
is short because in long run all factors are variable. (c) Is the answer because the law of diminishing returns is not applicable when the two inputs
are used in same proportion. When all factor inputs are increased by the same proportion, this law is not relevant.
(d) Is not the answer because the law of diminishing returns assumes that the state of technology is given and remains constant.
(e) Is not the answer because according to the law of diminishing returns, one factor of production must always be kept constant at a given level. So if capital is held constant, with varying labor, this law of diminishing returns holds good.
< TOP >
10. Answer : (d) Reason : An isoquant is a curve showing all combinations of inputs that can be used to produce a given
output. In case of perfect substitutes, the isoquant would be a negatively sloped straight line because inputs can be substituted and only one input can be employed for the production of goods desired. It would be L-shaped, in case of complementary goods as two inputs have to be used together simultaneously for the production of goods. For normal goods, isoquant would be convex to the origin because of decreasing marginal rate of substitutability. Hence (d) is the answer.
(a) Is not the answer because the shape of the isoquant will not be horizontal straight line. (b) Is not the answer because the shape of the isoquant will not be vertical straight line (c) Is not the answer because the shape of the isoquant will not be convex to the origin (d) Is the answer because the shape of the isoquant will be negatively sloped straight line (e) Is not the answer because the shape of the isoquant will not be L-shaped.

11. Answer : (b) Reason : Implicit cost is also known as opportunity cost. These costs are not paid out-of-the pockets. It
refers to income that could have been earned by factor input in their best alternative use. (a) Payments to the non-owners of the firm for the resources they supply constitute an out-of-
the- pocket cost. Hence (a) is not correct. (b) Implicit cost is also known as opportunity costs. It refers to income that could have earned by
factor input in their best alternative use. Money payment, which the self-employed resources could have earned in their best alternative employment, signifies opportunity cost of self-employed resources.
(c) An undisclosed cost does not constitute implicit costs. (d) Fixed cost is the cost that remains same during a period of time. Fixed costs consist of both
implicit and explicit costs. (e) Is not the answer because (b) is correct.
< TOP >
12. Answer : (b) Reason : (a) Profit will be maximum when the MC is equal to MR and the slope of MC curve > slope of MR curve
(b) As long as MC>AC, AC is increasing and as long as MC<AC, AC is decreasing. Therefore, when MC and AC are equal, AC is at its minimum.
(c) MC is minimum when slope of MC curve is zero (d) There is no relation between the intersection point of MC & AC and the opportunity cost (e) Profit will be minimum when the MC is equal to MR and the slope of MC curve < slope of
MR curve.
< TOP >
13. Answer : (b) Reason : I. When output becomes very large, average fixed cost approaches zero, but it never reaches
< TOP >
zero, if there is a certain amount of fixed costs. II. It is not true that AFC reaches minimum when MC interests AFC. AFC does not reach
minimum when MC cuts AFC. There is no minimum point of AFC III. It is not true that the shape of AFC curve is linear. The shape of average fixed cost curve is
rectangular hyperbola indicating that when the output increases by a certain percentage, the average fixed cost decreases by the same percentage such that their product representing total fixed cost remains constant thoughtout.
IV. Average fixed cost is maximum when output is zero. (a) Is not the answer because I above is true and II above is not true if the fixed cost of a
firm is Rs.10,000 (b) Is the answer because both II and III are not true if the fixed cost of a firm is Rs.10,000. (c) Is not the answer because II above is not true, while IV above is true if the fixed cost of
a firm is Rs.10,000 (d) Is not the answer because I above is true, while II and III above are not true if the fixed
cost of a firm is Rs.10,000 (e) Is not the answer because II and III above are not true, while IV above are true if the
fixed cost of a firm is Rs.10,000.
14. Answer : (d) Reason : The prices of inputs remain constant; a 15% increase in all inputs will increase the output by 15%
results in no change in average variable cost, fixed cost and marginal cost. (a) Is not the answer because average variable cost will not change as the output increases. (b) Is not the answer because fixed cost will not change as the output increases. Fixed cost
remains same at different level of output, even if the output is zero. (c) Is not the answer because marginal cost will not change as the output increases. (d) Is the answer because average variable cost, fixed cost and marginal cost will not change as
the output increases.
< TOP >
15. Answer : (d) Reason : Perfect competition is a form of market structure which represents a market without rivalry among
the individual firms. When the product is similar and identical, given all other conditions, a perfectly competitive firm can only be a price taker. The price of the good is determined by the market forces. The demand curve is horizontal to x-axis implying that the producers can produce as much as quantity of output to the given level of price. (a) Oligopoly is a form of market structure where there are few sellers. The demand curve is
indeterminable because of the interdependence between the firms and it depends on the reaction curves of the competitor.
(b) Monopoly is a form of market structure where there is only one producer of the good. The demand curve is downward sloping implying that the producer is a price-maker. The distinguishing feature of this form of market structure is that the average costs of production continually decline with increased output as a result of which average costs of production will be lowest when a single large firm produces the entire output demanded.
(c) Monopolistic competition is a market structure where there are many firms selling closely related but non-identical goods. The demand curve is downward sloping because of product differentiation.
(d) The demand curve in the perfect competition is horizontal to x-axis implying that producer can produce as much as the quantity of output for a given level of price.
(e) The demand curve of a duopolist is indeterminate because of high degree of interdependence between the firms.
Hence, the correct answer is (d).
< TOP >
16. Answer : (c) Reason : If any firm earns more than normal profits, new firms will enter the industry in the long run,
leading to fall in good prices. This decline in the price reduces the volume of profits of the existing firms. This process continues till all existing firms earn only normal profits. On the contrary, when existing firms get losses, some of the firms leave the industry. This increases the price of good. This process continues till the existing firms get normal profits.
< TOP >
(a) Product homogeneity in the industry ensures equal price for the good in the industry, but it does not result in normal profits.
(b) Presence of large number of sellers and buyers in the industry does not allow individual buyer or seller, however large, to influence the price by changing the purchase or output.
(c) Free entry and exit of firms in an industry ensures normal profits in the long run as higher profits increases the entry of new firms, while losses make existing firms to move out of the industry.
(d) As (a) and (b) are not the answers, (d) cannot be the answer. (e) As (b) is not the answer, (e) cannot be the answer.
17. Answer : (a) Reason : A perfectly competitive firm is in equilibrium only when P = MR =MC because in perfect
competition, MR = P. (a) Is the answer because a perfectly competitive firm is in equilibrium only when P = MR =MC. (b) Is not the answer because a perfectly competitive firm is not in equilibrium when P = MR, but
MR > MC. (c) Is not the answer because a perfectly competitive firm is not in equilibrium when P = MC,
but MR < MC. (d) Is not the answer because a perfectly competitive firm is not in equilibrium when MR = MC,
but P < MR. (e) Is not the answer because a perfectly competitive firm is not in equilibrium when MR= MC,
but P > MR.
< TOP >
18. Answer : (e) Reason : Least-cost production implies that the producer produces a given level of output where the
marginal physical product to the factor price ratio is equal to the factor inputs. (a) It is not appropriate in this instance because it is indicating that all factor prices are equal
indicates the demand and supply of that factor. (b) It is not appropriate in this instance because it indicates the addition to total output by the
employment of an additional unit of a factor of production all else equal. (c) It is not appropriate in this instance because marginal physical product is the slope of the
total output curve and therefore will not indicate the least cost production. (d) It is not appropriate in this instance because it is not indicating the least-cost-production. (e) It is appropriate in this instance because, it is the change in the total revenue of the firm that
results from the employment of one additional unit of a factor of production. Therefore the marginal physical product to factor price ratio equal to the factor inputs indicates the least-cost production.
The correct answer is (e).
< TOP >
19. Answer : (c) Reason : In an oligopoly market there are few sellers so that there is interdependence among the sellers and
the sellers are aware of it. This encourages them to form cartels for their mutual benefits. Oligopsony is a complementary form of oligopoly, where there exists a few buyers and a large number of sellers. Cartels imply direct agreement among competing oligopolists with the aim of reducing uncertainty. Hence, (c) is the correct answer.
(a) Is not the answer because cement industry is India is not a monopoly. Monopoly indicates a market structure characterized by a single seller.
(b) Is not the answer because cement industry is India is not perfectly competitive. In a perfectly competitive market, there are large numbers of buyers and sellers in the market.
(c) Is the answer because cement industry is India is an oligopoly (d) Is not the answer because cement industry is India is not a monopsony. (e) Is not the answer because cement industry is India is not an oligopsony.
< TOP >
20. Answer : (c) Reason : Monopoly is a market structure in which there exists a only a single seller. There are no close
substitutes for the product and there are barriers to entry in to the industry. In India, the Government of India is the only producer of atomic energy and there are barriers to entry for the
< TOP >
private entrepreneurs. So, atomic energy best illustrates a monopoly. (a) Is not the answer because agriculture is not a monopoly in India, rather it is a perfectly
competitive market. (b) Is not the answer because automobile industry is not a monopoly in India, rather it is an
oligopoly. (c) Is the answer because atomic energy is a monopoly in India. (d) Is not the answer because cola drinks is not a monopoly in India. (e) Is not the answer because television industry is not a monopoly in India.
21. Answer : (b) Reason : Stock is a variable which is measured at a point of time.
(a) GDP is the money value of goods and services produced within the domestic territory of a country (which includes depreciation) in a year and hence not a stock because it is measured over a period of time, usually a year.
(b) Inventories refer to the unsold stock or the raw materials maintained by a firm to be use in the production process. Hence it is measured at a point of time, i.e., number of unsold goods as on 31 March, 2003 are 100. Hence, it is a stock variable
(c) Inflation refers to persistent increase in prices over a period of time. It is measured over a period of time hence it is a flow and not a stock variable.
(d) National Income is the sum of factor income and labour income earned by the residents of a country earned usually over a period of one year. Hence it is also a flow concept.
(e) Since (a) and (d) are not correct options, (e) cannot be the right answer.
< TOP >
22. Answer : (a) Reason : Since the value added within the domestic territory will belong to the domestic factor inputs, NDP
at factor cost must be equal to domestic factor income. Hence answer is (a). (b) Is not the answer because the net factor income earned within the domestic territory of a
country is not equal to Net Domestic Product at market price. (c) Is not the answer because the net factor income earned within the domestic territory of a
country is not equal to Net National product at factor cost (d) Is not the answer because the net factor income earned within the domestic territory of a
country is not equal to Net National Product at market price (e) Is not the answer because the net factor income earned within the domestic territory of a
country is not equal to Personal income.
< TOP >
23. Answer : (d) Reason : GDP refers to money value of final goods and services produced within the domestic territory of a
country including depreciation. There are certain goods which are produced but will not be included in GDP. For example services of house wives (a) Bobby purchase of a new suit is nothing but the consumption expenditure of bobby, which is part of GDP (b) Purchase of new Ford car also refers to consumption expenditure and hence part of GDP (c) New computer purchased by community Bank for its loan office refers to purchase of capital goods. Hence it is part of capital expenditure and hence part of GDP (d) Tomatoes grown in home garden by Market are not taken as part of GDP Even though goods are produced, they are not taken as part of GDP as it refers to production for self consumption. If she sells them in the market then it becomes part of GDP. (e) Fort India could not sell 100 cars, hence they are part of inventories and hence part of capital expenditure. Hence included in GDP as part of capital goods expenditure.
< TOP >
24. Answer : (e) Reason : (a) Consumption depends on the income and as income increase consumption also increase.
(b) Propensity to consume refers to the changes in consumption as a result of change in income. Hence propensity to consume effects consumption.
(c) Propensity to save refers to changes in savings as a results of changes in income. The level of savings affects the level of consumption. Hence changes in savings does affect consumption
< TOP >
(d) Consumption demand does not depend upon the level of wealth (e) Consumption demand does not depend upon the level of marginal efficiency of
investment.
25. Answer : (a) Reason : When investment < Depreciation, capital stock decreases and net investment will be negative.
Note that capital consumption is nothing but depreciation. (a) Is the answer because when the addition to capital goods in an economy is less than the capital
consumption allowance, the economy experiences negative net investment (b) Is not the answer because the economy does not experience zero net investment (c) Is not the answer because the economy does not experience positive net investment (d) Is not the answer because the economy does not experience negative gross investment (e) Is not the answer because the economy does not experience zero gross investment.
< TOP >
26. Answer : (e) Reason : APS + APC = 1 If APS < 0, APC > 1
(a) Is not the answer because when the average propensity to save (APS) is negative, then the average propensity to consume (APC) is not negative
(b) Is not the answer because when the average propensity to save (APS) is negative, then the average propensity to consume (APC) is not zero
(c) Is not the answer because when the average propensity to save (APS) is negative, then the average propensity to consume (APC) is positive but not less than one
(d) Is not the answer because when the average propensity to save (APS) is negative, then the average propensity to consume (APC) is not one
(e) Is the answer because when the average propensity to save (APS) is negative, then the average propensity to consume (APC) is greater than one.

27. Answer : (a) Reason : In the Keynesian model, unemployment could be reduced if the aggregate demand increases.
Therefore, unemployment is caused by demand deficiency. The Keynesian theory of unemployment suggests that governments can play an active role in the economy by adjusting the aggregate demand through its fiscal and monetary instruments. (a) Is the answer because unemployment in the Keynesian model is caused by demand
deficiency. (b) Is not the answer because unemployment in the Keynesian model is not caused by supply
deficiency. (c) Is not the answer because unemployment in the Keynesian model is not caused by demand
sufficiency. (d) Is not the answer because unemployment in the Keynesian model is not caused by supply
sufficiency. (e) Is not the answer because unemployment in the Keynesian model is not caused by both
demand deficiency and supply deficiency.
< TOP >
28. Answer : (a) Reason : An important difference between the approaches of the classical and Keynesian economists use to
achieve a macroeconomic equilibrium is that Keynesian economists actively promote the use of fiscal policy; the classical economists do not. Classical economists believe intervention can be de-stabilizing and advocate laissez- faire economy. Therefore the answer is (a).
(a) Is the answer because Keynesian economists actively promote the use of fiscal policy while the classical economists do not
(b) Is not the answer because Keynesian economists actively promote the use of monetary policy to improve aggregate economic performance while classical economists artificially separated the monetary theory from the value theory.
< TOP >
(c) Is not the answer because classical economists do not believe that monetary policy will certainly affect the level of output.
(d) Is not the answer because Classical economists do not believe that fiscal policy is an effective tool for achieving economic stability while Keynesians do.
(e) Is not the answer because none of the above cannot be the answer.
29. Answer : (d) Reason : Money supply = Currency in the hands of the public + Demand Deposits with banks. A rupee
deposited in a bank reduces currency by Rs.1 but raises deposits by Rs.1, and hence does not affect the money supply in the system. As banks are holding entire deposits in reserves, it cannot affect money multiplier and hence supply of money. (a) If banks maintains 100% of their deposits as reserves, there could be no lending and hence no
deposit creation. Thus, when the reserve ratio is 100%, the banking system can no longer affect the money stock in the country.
(b) Money supply = Money multiplier x High-powered money (H). When the banks maintain 100% reserves, the value of money multiplier will be 1. Hence, change in the foreign exchange reserves leads to an equal change in the money supply.
(c) If banks have to maintain 100% of their deposits with RBI, then naturally the lending capacity of banks would be narrowed down to zero.
(d) A rupee deposited in a bank reduces the currency with the public, but at the same time increases the deposits of the banks. Hence, there will be no affect on the money supply in the economy. Hence, the statement is not correct.
(e) Money supply = Money multiplier x High-powered money (H). When banks maintain 100% reserves, then the value of money multiplier will come down to 1. If the value of money multiplier is 1, then naturally the money supply must be equal to high-powered money.
< TOP >
30. Answer : (e) Reason : Contractionary (tight) fiscal policy involves increasing tax rate and/or decreasing the government
spending to bring down the aggregate demand and price level in the economy. Reduced government spending reduces the public borrowings, and thereby interest rate and output in the economy. The tight monetary policy, conversely, reduces the money supply and thereby increases the interest rate in the economy. Increased interest rate reduces both consumption and investment and thereby reduces output in the economy. Thus, we can say that the combined effect of tight fiscal policy and tight monetary policy lowers the output. But, the direction of change in interest rate is not known unless we know the magnitude of influence of fiscal and monetary policies on interest rate.
I. A contractionary fiscal policy combined with a tight monetary policy result in a lower level of output.
II. A contractionary fiscal policy combined with a tight monetary policy do not result in a higher level of output.
III. A contractionary fiscal policy combined with a tight monetary policy do not result in a lower interest rate
IV. A contractionary fiscal policy combined with a tight monetary policy result in a higher interest rate
V. A contractionary fiscal policy combined with a tight monetary policy result in a lower or higher interest rate depending on the relative magnitude of fiscal and monetary policies. So, the answer is (e).
< TOP >
31. Answer : (a) Reason : Stagflation refers to a situation where there is high unemployment and high inflation occurs
simultaneously. Statement I is true as stagflation refers to coexistence of stagnant output and high inflation. Statement II is false because during stagflation, there is no increase in output and hence the output is stagnant. Therefore real GDP is not growing. Statement III is true because during stagflation, the output is stagnant, new employment
< TOP >
opportunities are not created and hence unemployment level is high. Statement IV is false as the price are high and there is unemployment, the aggregate demand tends to be low.
So the answer is (a).
32. Answer : (e) Reason : Inflation is a serious problem on the part of the government worldwide. The effect of inflation is
ranging from redistribution of income and wealth of the society to the worsening the balance of payments position of the country. (a) It is true statement that unanticipated inflation hurts the fixed income earners most. Though
their monetary income is constant, real income is reduced because of inflation. (b) It is true statement that higher than expected inflation hurts creditors but benefits debtors.
Debtors repay the amount, which is fixed in nominal terms. The real values of repayments in the future will decrease with an increase in inflation, leads to an increase in the wealth of the debtors. On the other hand, the wealth of the creditors will decrease with an increase in the rate of inflation.
(c) It is a true statement that inflation creates inefficiency in the economy because people spent lot of time to find a reasonable price.
(d) It is a true statement that inflation can lead to a misallocation of resources because inflation misleads people to invest logically.
(e) Is the answer because all the above statements are correct.

33. Answer : (c) Reason : Monetized deficit refers to increase in net RBI credit to the Central Government, comprising the
net increase in the holdings of T-bills of the RBI and its contribution to the market borrowings of the Government. Fiscal deficit = Borrowings and liabilities of the Central Government and primary deficit = Fiscal deficit – interest payments. (a) Is not the answer because monetized deficit doesn’t refer fiscal deficit minus interest
payments (b) Is not the answer because monetized deficit doesn’t refer borrowings and other liabilities of
the Central Government (c) Is the answer because monetized deficit refers Increase in the net RBI credit to the Central
Government (d) Is not the answer because monetized deficit doesn’t refer fiscal deficit minus Primary deficit (e) Is not the answer because monetized deficit doesn’t refer RBI’s credit to the commercial
banks.
< TOP >
34. Answer : (e) Reason : If a government has a surplus budget, and the government repays its past debts using its surplus
budget, public debt will be falling. (a) Is not the answer because if a Government is running surplus in its budget, public debt may
not be rising. (b) Is not the answer because if a Government is running surplus in its budget, public debt may
not be falling. (c) Is not the answer because if a Government is running surplus in its budget, public debt may
not be constant. (d) Is not the answer because if a Government is running surplus in its budget, public debt may
not be falling if there are tax cuts. (e) Is the answer because if a Government is running surplus in its budget, public debt will be
falling if the Government uses the surplus to repay its past debts.
< TOP >
35. Answer : (a) Reason : Creation of credit is a major function of a commercial bank. When a bank creates credit or
advances loans, there tends to be a multiple expansion of credit in the banking systems. (a) Is the answer because credit creation by the commercial bank is limited by the Cash Reserve
Ratio(CRR), i.e. every commercial bank must keep on deposit with the Reserve Bank certain amounts of funds equal to a specified percentage of it’s own deposit liabilities.
(b) Is not the answer because commercial banks cannot create as much credit as they want.
< TOP >
(c) Is not the answer because RBI has control over the credit created by commercial banks. (d) Is not the answer because CRR has an impact on credit creation.
36. Answer : (d) Reason : (a) Reserves with RBI (both surplus reserves and statutory reserves) are assets of a commercial
bank. (b) Loans given to public sector undertakings are assets of the banks. (c) Credit given to any individual, firm or government is an asset to the bank lended. (d) Deposits from the public are liabilities to the bank because it has to repay the amount at a

37. Answer : (d) Reason : Preparation of BoP statement is based on double-entry system of book keeping. Hence, all debt
items should equal credit items, and the balance is zero. (a) Is not the answer because all entries in the balance of payments statement is not collectively sum to
GDP of the country (b) Is not the answer because all entries in the balance of payments statement is not collectively sum to
GNP of the country (c) Is not the answer because all entries in the balance of payments statement is not collectively sum to
foreign exchange reserves of the country (d) Is the answer because all entries in the balance of payments statement is collectively sum to zero (e) Is not the answer because all entries in the balance of payments statement is not collectively sum to
Exports of the country.
< TOP >
38. Answer : (b) Reason : Because of the double entry concept underlying the recording of transactions, BoP account must
always be in balance. Thus, ‘Balance in current account + Balance in capital account + Change in reserves = Zero’. When there is no change in the foreign exchange reserves, then ‘balance in current account + balance in capital account = zero’ (or) balance in current account = - (balance in capital account). (a) Balance in current account + Balance in capital account = Change in reserves. When balance
in current account ‘plus’ balance in capital account is zero, then balance in the current account = - balance in capital account. Hence, statement (a) is not correct.
(b) There will no change in the foreign exchange reserves of a country only when surplus (deficit) in current account is equal to deficit (surplus) in capital account.
(c) Current account balance may or may not be zero when the change in foreign exchange reserves of a country is zero.
(d) Trade balance (exports – imports) may or may not be zero when the change in foreign exchange reserves of a country is zero.
(e) Capital account balance may or may not be zero when the change in foreign exchange reserves of a country is zero.

41. 42. Answer : (c)
Reason : Monopoly is a market structure in which there is one seller of the product implying that the producer has complete control over market supply of the commodity. The monopolist must decrease the price he receives for every unit in order to sell an additional unit. Hence, the marginal revenue of the monopolist would be lesser than price. Hence, the correct answer is (c).
(a) Is not the answer because in monopoly, price is not lesser than marginal revenue. (b) Is not the answer because in monopoly, price is equal to average revenue. (c) Is the answer because in monopoly, price is greater than marginal revenue. (d) Is not the answer because in monopoly, price is not equal to total revenue. (e) Is not the answer because option (b) above is not true, while option (c) is true. So, the answer is (c).

44. Answer : (d) Reason : Marginal Utility is change in Total Utility when additional unit of the good is consumed. If MU is
negative, Total Utility will be decreasing. (a) As long as marginal utility is positive, total utility will be increasing. (b) Total utility will be at its minimum point when marginal utility is zero and the derivative of
marginal utility (second derivative of total utility) is positive. (c) Total utility will be at its maximum point when marginal utility is zero and the derivative of
marginal utility (second derivative of total utility) is negative. (d) When marginal utility falls below zero, the total utility starts falling. Hence (d) is the answer. (e) Marginal utility can be negative; which implies that a consumer is deriving negative
satisfaction by consuming one additional unit.

45. Answer : (e) Reason : (a) Long run average cost (LAC = LTC/Q) is U-shaped because of economies of scale initially
and diseconomies of scale at later stages of production. (b) Long run marginal cost (LMC = ∂LTC/∂Q) is U-shaped as cost of producing additional units
reduces at the beginning because of economies of scale, but raises later due to diseconomies of scale.
(c) & (d) Short run average cost (SAC = STC/Q) and AVC (= TVC/Q) falls and raises due to operation of ‘law of diminishing marginal productivity’.
(e) Average fixed cost (AFC = TFC/Q) falls at a decreasing rate with the increase of output because of constant total fixed cost.

48. Answer : (d) Reason : Phillips curve shows the relationship between the unemployment and inflation. In short-run there
exist inverse relationship between inflation rate and unemployment rate because actual rate of inflation is not always the same as the expected rate. But in the long run, the actual rate of inflation equals expected rate and hence the economy automatically reach its natural rate of unemployment. As there is no trade off between inflation and unemployment in the long run, the long run Phillips curve is vertical.
(a) Is not the answer because the long run Phillips curve is not an upward sloping curve (b) Is not the answer because the long run Phillips curve is not a downward sloping curve (c) Is not the answer because the long run Phillips curve is not a horizontal straight line (d) Is the answer because the long run Phillips curve is a vertical straight line (e) Is not the answer because the long run Phillips curve is not indeterminable.

50. Answer : (b) Reason : Monetary policy mainly controls the economy by regulating the interest rates through changes in
money supply. If the private investment is more sensitive to interest rate, then monetary policy can more effectively regulate the economy. (a) A recessionary condition cannot make a monetary policy more effective. (b) When private investment is more sensitive to interest rate monetary policy will be more
effective as a small change in the interest rate would lead to a greater change in the output. (c) Monetary policy will not be more effective when the private investment is less sensitive to
interest rate. (d) During liquidity trap, the effectiveness of monetary policy decreases because during such
policy, changes in interest rate cannot have any effect on investments. (e) Effectiveness of the monetary policy is not determined by the phases of business cycle.

51. Answer : (a) Reason : Price elasticity of demand = ∂Q/∂P × P/Q
Given P = 10 Demand function: P = 20 – 2Q Or, 2Q = 20 – P Or, Q = 10 – 0.5P
Thus, ∂Q/∂P × P/Q = -0.5 × 10/5 = -1
< TOP >
52. Answer : (b) Reason : Qs = 400P – 500
Qd = 1500 – 100P
Equilibrium price is determined when Qs = Qd.
∴ 400P – 500 = 1500 – 100P or, 500P = 2000 or, P = 4
When P = 4, Qs = 400(4) – 500 = 1600 – 500 = 1100.

54. Answer : (d) Reason : When price is Rs.75, demand is 10 units When price is Rs.70, demand is 12 units If the demand is linear, then Q = a + bP Where, b = Change in quantity demanded/Change in price = (12 – 10)/(70 – 75) = 2/(-5) = -0.4.
Thus, Q = a – 0.4P At Rs.75, 10 = a – 0.4(75) Or, a = 40 Thus, demand function = Q = 40 – 0.4P The maximum quantity can be demanded when the price is zero. Hence, maximum quantity
demanded = 40 – 0.4(0) = 40 units.

73. Answer : (c) Reason : C = α + βYd
Where, α = autonomous consumption and β = marginal propensity to consume (MPC) β = ∆C/∆Yd = (475 – 400)/100 = 0.75
If MPC = 0.75, autonomous consumption: 475 = a + 0.75(500) Or, a = 100. Thus, C = 100 + 0.75Yd
Or, S = – 100 + 0.25Yd
When S = 100, 100 = –100 + 0.25Yd
or, 200 = 0.25Yd
or, Yd = 800
Since the economy is a two sector economy, Y = Yd (disposable income).
