109. Over short period, when income
rises, average propensity to consume usually
(1) rises
(2) falls
(3) remains constant
(4) fluctuates
Answer:
109. (2) Keynes postulated that aggregate consumption is
a function of aggregate current disposable income.
The Keynesian consumption function is written as:
C = a + cY a > 0, 0 < c < 1; where a is the intercept, a constant which measures consumption at a
zero level of disposal income; c is the marginal propensity to consume (MPC); and Y is the disposal income. So as income increases, average propensity
to consume (APC = C/Y) falls.

116. Savings rate is relatively low in
developed economies because of
(1) Low per capita income
(2) Welfare programmes
(3) Liquidity/Borrowing constraint
(4) High interest rate
Answer:
116. (2) As a general rule, saving is considered as a derivative of consumption. Developed economies have lower
saving rates than developing countries because at the
same income level, the level of consumption is higher
in their cases. Besides, as seen in the recent case of
the United States, welfare programmes have been found
to be responsible for falling saving rate. Redistributing
from young and future generations to older generations raises national consumption and lowers national
saving (The Concise Encyclopedia of Economics).

found the relationship between interest rates (nominal interest rate and real interest rate) and the consumption level. Though his theory is about interest
rate and inflation, it discusses the effect of real interest rate on savings and gives an inverse relationship
between nominal interest rates and consumer expenditures.

121. Regarding money supply situation in India it can be said that
the :
(1) Currency with the public is
inconvertible only.
(2) Currency with the public is
less than the deposits with
the banks.
(3) Currency with the public is
more than the deposits with
the banks.
(4) Currency with the public is
almost equal to the deposits
with banks.
Answer:
121. (2) Money supply in India includes the following: (i)
Currency with the public; (ii) Demand deposits and
time deposits with banks; (iii) Deposits with reserve
Bank of India; and (iv) Deposits in Post Office. The
currency with public is less than the total currency
issued by RBI. This is because of cash reserves with
banks, i.e., a part of currency issued remains with
banks. As far as deposits are concerned, during the
last four decades, the proportion of demand deposits, time deposits and other with banks in relation to
total supply of money has been increasing with reciprocal diminution in currency held by the public. This
is mainly due to the expansion of banking facilities in
the country. Almost all the money in the economy
exists as bank deposits – and banks create these
deposits simply by making loans.

is a/an :
(1) increase in supply combined
with a decrease in demand.
(2) increase in both demand and
supply.
(3) decrease in both demand and
supply.
(4) increase in demand accompanied by a decrease in supply.
Answer:
122. (4) Price of a commodity is always determined by the
forces of demand and supply in the market. The price
at which the amount demanded and amount supplied
are equal is known as ‘equilibrium price.’ The equilibrium price definitely increases when there is an increase in demand combined with the decrease in
supply.

a proportionate change in output, it is case of
(1) Constant returns to scale
(2) Diminishing returns to scale
(3) Increasing returns to scale
(4) Variable returns to scale
Answer:
123. (1) If output increases by that same proportional change
as all inputs change then there are constant returns
to scale (CRS). If output increases by less than that
proportional change in inputs, there are decreasing
returns to scale (DRS). If output increases by more
than that proportional change in inputs, there are
increasing returns to scale (IRS).

124. Which of the following is a consequence of inflationary price
rise ?
(1) Obstacle in development
(2) Increase in economic inequalities
(3) All of these
(4) Adverse effect on the balance of payment
Answer:
124. (3) Inflationary price rise is harmful to a country’s
economic performance and to the welfare of its citizens. It can create a random redistribution of income
given that inflation does not have an equal impact on
individuals and groups. The balance of payments may
deteriorate because domestic inflation stimulates import spending, given that imports appear relatively
cheaper, and dampens export sales. A continuous
price rise can be an obstacle to development as it has
an adverse effect on saving and investment and causes a fall in growth.

(1) arise when there is expansion
in an industry.
(2) arise in an economy as it
makes progress.
(3) accrue to a firm when it expands its output.
(4) arise when there is expansion
in internal trade.
Answer:
126. (1) Internal economies are those economies in production—those reductions in production costs—which
accrue to the firm itself when it expands its output
or enlarges its scale of production. The internal economies arise within a firm as a result of its own expansion independent of the size and expansion of

128. Which of the following costs is
related to marginal cost?
(1) Variable Cost (2) Implicit Cost
(3) Prime Cost (4) Fixed Cost
Answer:
128. (1) In economics, marginal cost is the change in the
total cost that arises when the quantity produced is
incremented by one unit. That is, it is the cost of
producing one more unit of a good. Marginal cost is
independent of the fixed cost and depends on the
changes in the variable factors. Since fixed costs do
not change with output, there are no marginal fixed
costs when output is increased in the short run. It is
only the variable costs that vary with output in the
short run. Therefore, the marginal costs are in fact
due to the changes in variable costs, and whatever
the amount of fixed cost, the marginal cost in unaffected by it.

(1) Boom (2) Depression
(3) Famines (4) War
Answer:
129. (2) Surplus budget is a budget in which government
receipts are greater than government expenditures.
Such a budget is desired when the economy is battling inflation due to excess aggregate demand (AD).
Surplus budget plugs the inflationary gap by lowering the level of aggregate demand. AD is lowered on
account of (i) rise in revenue collection by the government, and (ii) fall in government expenditure.

130. Economic profit or normal profit
is the same as :
(1) optimum profit
(2) accounting profile
(3) maximum profit
(4) net profit
Answer:
130. (4) Normal profit or economic profit is an economic
condition occurring when the difference between a
firm’s total revenue and total cost is equal to zero.
Simply put, normal profit is the minimum level of profit
needed for a company to remain competitive in the
market. In a sense, normal profit is the same as
net profit which is calculated by subtracting a company’s total expenses from total revenue, thus showing what the company has earned (or lost) in a given
period of time. Accounting profit occurs when revenues are greater than costs, and not equal, as in the
case of normal profit.

131. When income increase, consumption also increases :
(1) in a lower proportion
(2) in a higher proportion
(3) in the same proportion
(4) None of the options
Answer:
131. (1) According to the Keynesian Consumption theory,
“men are disposed, as a rule and on average, to increase their consumption as their income increases,
but not by as much as the increase in their income.”
Another feature of consumer behavior is that when
income increases, people do not spend their entire
incremental income on consumption. They save a part
of it for their financial security during the period of
unemployment, illness, etc. In simple words, the marginal propensity to consume decreases, i.e., households spend a decreasing proportion of marginal income on consumption. That is why families on lower
income scale save a lower percentage of their income
and those on higher scale of income save a larger
proportion of their income.

132. The total utility from 9 units of
commodity x is 20 and from 10
units is 15. Calculate the marginal utility from 10th unit.
(1) 0.5 (2) –0.5
(3) 5 (4) –5
Answer:
132. (4) Marginal Utility = Change in Total Utility / Change
in number of Units consumed. The first component
of the formula is to calculate the change in total utility. The second component of the marginal utility formula is the change in the number of units that have
been consumed. This is done by subtracting the number that is currently being consumed from a previously consumed amount.
So Marginal Utility (MU) from 10th Unit = TU10 - TU9=

(1) Reducing public expenditure
(2) Price control through Public
Distribution System
(3) Higher taxation to mop up liquidity
(4) Credit control
Answer:
134. (2) The issue of inflation is addressed from both demand and supply sides. demand management is
achieved by measures such as postponing public expenditure, mopping up excess liquidity either through
taxes or savings schemes, etc. On the supply side,
the mechanism of Public Distribution System (PDS)
ensures availability of essential commodities for the
vulnerable sections of society. This helps to maintain
price levels. Coupled with this is the open market
sale of rice and wheat resorted to by FCI from its
buffer stock in times of price rise.

principle that maintains that taxes should be levied
according a taxpayer's ability to pay. It is concerned
with the equitable distribution of taxes according to
the stated taxable capacity or ability to pay of an
individual or group. The emphasis in this approach

by a firm in the short-run product of a good or service and the quantity produced. it is relatively high at
small quantities of output, then declines as production increases. It is downward sloping because as
output increases, the firm spreads its fixed costs
over larger and larger amounts of output.

138. In which of the following market
forms, a firm does not exercise
control over price?
(1) Monopoly
(2) Perfect competition
(3) Oligopoly
(4) Monopolistic competition
Answer:
138. (2) In perfect competition, the existence of a large
number of firms producing and selling the product
ensures that an individual firm exercises no influence
over the price of the product. The output of an individual firm constitutes a very small fraction of the
total output of the whole industry so that any increase
or decrease in output by an individual firm has a negligible effect on the total supply of product of the industry. As a result, a single firm is not in a position to
influence the price of the product by the increasing or
reducing its output.

143. (2) In microeconomics, an Engel curve describes how
household expenditure on a particular good or service
varies with household income. The curve is named
after the German statistician Ernst Engel (1821–1896),
who was the first to investigate this relationship between goods expenditure and income systematically
in 1857.

144. Malthusian theory is associated
with which of the following ?
(1) Poverty (2) Employment
(3) Diseases (4) Population
Answer:
144. (4) The most well-known theory of population is the
Malthusian theory.It explains the relationship between
the growth in food supply and in population. It states
that population increases faster than food supply and
if unchecked leads to vice or misery. Thomas Robert
Malthus enunciated his views about population in his
famous book, Essay on the Principle of Population as
it affects the Future Improvement of Society, published in 1798.

145. When average product of an input is at its maximum then :
(AP= Average product)
(MP= Marginal product)
(1) AP = 0 (2) AP = MP
(3) AP > MP (4) AP < MP
Answer:
145. (2) There is a close relationship between marginal product and average product because both are derived
from total product. When marginal product is equal to
average product, the average product is at its maximum. In the short-run production function, since marginal product starts off as greater than average product and then falls below average product, we can assume that at the “cross-over point,” when MP = AP,
AP is at its maximum.

146. If total product is at its maximum then:
(AP= Average product)
(MP= Marginal product)
(1) AP = 0 (2) AP < 0
(3) MP = 0 (4) AP = MP = 0
Answer:
146. (3) Total product (TP) is the total output a production
unit can produce, using different combination of factors of production. When marginal product =0 (at point
D in the figure), the total product is at its maximum
(as seen at point C in the figure given below). Then en
as the marginal product becomes negative, the total
product starts going down.

147. Equilibrium output is determined by:
(1) the equality between total
Variable cost and Marginal
revenue.
(2) the equality betweem Marginal cost and Marginal revenue.
(3) the equality between Average cost and Average revenue.
(4) the equality between total
cost and total revenue.
Answer:
147. (2) Equilibrium Output refers to the level of output
where the Aggregate Demand is equal to the Aggregate Supply (AD = AS) in an economy. It signifies that
whatever the producers intend to produce during the
year is exactly equal to what the buyers intend to buy
during the year. According to MR-MC approach, equilibrium refers to stage of that output level at which
Marginal Cost (MC) = Marginal Revenue (MR). As long
as MC is less than MR, it is profitable for the producer to go on producing more because it adds to its
profits. He stops producing more only when MC becomes equal to MR.

148. An employer goes on employing
more and more of a factor units
until :
(1) the Average Revenue Productivity becomes equal to Marginal Revenue Productivity.
(2) the Marginal Revenue Productivity becomes zero.
(3) the Diminishing Marginal Returns sets into operation.
(4) the Marginal Revenue Productivity of a factor becomes
equal to its reward.
Answer:
148. (4) According to the Marginal Productivity Theory, the
reward or the price of a factor unit depends upon its
productivity or its contribution to the total product.
While employing a factor, an employer compares the
marginal revenue productivity (MRP) of the lost unit
and the marginal cost of the factor. He will employ a
factor up to the point where the reward (marginal cost
of the factor) paid to the factor equals its MRP. If MRP
is more than the marginal cost, the employer increases its profits by employing more units of the factor;
on the other hand, if marginal cost of the factor is
greater than MRP, it will reduce employment to reduce its loss.

149. Apart from the availability of raw
material location of an industry
is also dependent on the availability of:
(1) enviornmental protection and
vegetation
(2) man power and energy
source
(3) transport and bio energy
(4) water and inputs
Answer:
149. (2) Some of the factors which affect the industrial location are as follows: availability of raw materials, availability of labour, availability of capital, availability of
power, availability of market and infrastructure. good
supply of labor is one of the traditional factors that is
indispensable for industry. Besides, availability of power/electricity is also a deciding factor.

150. What happens when there is a
demand deficiency in an economy?
(1) Poverty (2) Stagnation
(3) Recession (4) Inflation
Answer:
150. (2) Deficient demand refers to the situation when
aggregate demand for goods and services falls short
of aggregate supply of output which is produced by
fully employing the given resources of the economy.
This deficient demand leads to the decrease in output,
employ-ment and prices in the econo-my. According
to Malthus, deficiency of demand could lead to
stagnation in which both capital and labor are
redundant relative to the opportunities for employing
them profitably.
