Answers

Answer 1.
a. Excess demand

Answer 2.
The ratio of nominal to real GDP

Answer 3.
iii. Monopoly

Answer 4.

Answer 5.
ii. 1936

Answer 6.
The ratio of nominal GDP to real GDP is known as GDP deflator

Answer 7.
Multiplier (K) = 1/1 – MPC
That is K = 1/1 – 0.5
K = 1/0.5
K = 2
Increase in total income = K x increase in investment = 2 x 500 crores = 1000 crores

Answer 11.
THE SHORT RUN AND THE LONG RUN.
In the short run, a firm cannot vary all the inputs. One of the factors – factor 1 or factor 2 – cannot be varied, and therefore, remain fixed in the short run. In order to vary the output level, the firm can very only the other factor. The factor that remains fixed is called the fixed input whereas the other factor which the firm can vary is called the variable input. In the long run, all factors of production can be varied. A firm in order to produce different levels of output in the long run may vary both the inputs simultaneously. So, in the long run, there is no fixed input. For any particular production process, long run generally refers to a longer time period than the short run. For different production : processes, the long run periods may be different. It is not advisable to define short run and long run in terms of say, days, months or years. We define a period as long run or short run simply by looking at whether all the inputs can be varied or not.

Answer 12.

Answer 13.
The monopolistically competitive firm could sell more of the commodity only by reducing the price. In case of monopolistic competition, the firm expects small increase in demand if it lowers the price. Hence the marginal revenue is slightly less than the average revenue.

Answer 14.
The consumer’s budget set would consist of all bundles (x₁, x₂) such that x₁ and x₂ are any numbers greater than or equal to 0 and p₁x₁ + p₂x₂≤M.
All bundles in the positive quadrant which are on or below the line are included in the budget set. The equation of the line is p₁x₁ + p₂x₂ = M.

Answer 15.
Point E is considerd as consumer’s optimum. The optimum bundle of the consumer is located at the point where the budget line is tangent to one of the indifference curves, it is drawn below.

Condition I : Budget line should be tangent to the indifference curve.

Condition II : Slope of IC should be equal to slope of budget line.

Answer 16.

Answer 17.

Answer 18.

Answer 19.
i. S₁ elastic supply
S₂ Unitary elastic supply
S₃ Inelastic supply
ii. Geometric method is applied here.

Answer 20.
a. Perfect competition, monopoly
b. Under perfect competition, firm is price taker
Therefore, AR = MR
Under monopoly, firm is price maker,

Answer 21.
a. The equation of the budget line is
P₁x₁ + P₂x₂ = M
Where P₁ and P₂ are prices of good 1 and good 2. x₁ and x₂ are quantities of goods and M is his money income
b. X₁ = M/P₁ = 20/4 = 5 units

Answer 22.
a. Price ceiling increases the demand for wheat. As supply becomes less, there will be shortage of wheat as shown in the diagram.


b. Price ceiling is a situation when the price charged is more than or less than the equilibrium price determined by market forces of demand and supply.

c. Price ceiling also reduce the quality of products as suppliers have less financial resources to reinvest in their business

* Price ceiling will also encourage black markets to thrive in an economy. Shortage in the free market makes the consumer to look for commodities in the black market even though they are highly price.

Answer 23.
Three real value added in the production process is called Gross value added.

Gross value added = Value of output – Intermediate consumption
Gross value added = 5000 – 2000 = 3000

Answer 24.

Answer 25.

Answer 26.
It is usually accepted that an increase in MPs leads to a decrease in saving. This is because, if all the people of the economy increase the proportion of income they save, the total value of savings in the economy will not increase it will either decline or remain unchanged. This result is known as the ‘Paradox of shift’ which states that as people become more thrifty they end up saving less or same or more.

Answer 27.

Answer 28.
a. The total stock of money in circulation among the public at a particular point of time is called money supply. RBI publishes figures for four alternative measure’s of money supply, viz. M1, M2, M3 and M4. They are defined as follows.

b. i. M1 and M2 are narrow money
ii. M3 and M4 are broad money
M1 and M2 are known as narrow money. M3 and M4 are known as broad money. These gradations are in decreasing order of liquidity. M1 is most liquid and easiest for transactions where as M4 is least liquid of all. M3 is the most commonly used measure of money supply, it is also known as aggregate monetary resources.

Answer 29.
a. (i) Budget line or Budget constraint

(ii) Consumer’s Equilibrium

b. • Downward slopping
• Cover to the origin
• Two indifference curves never intersect
• Higher IC shows higher level of satisfaction
c. Yes. because any point on the budget line other than the point at which it touches the indifference curve lies on lower indifference curve and hence is inferior. Therefore such a point cannot be the consumer’s optimum bundle is located on the budget line at the point where the budget line is tangent to an indifference curve.

Answer 30.
a. A country’s exchange rate regime where its currency is set by the foreign – exchange market through supply and demand for that particular currency relative to other currencies. Thus, floating exchanges rates change freely and are determined by trading in the forex market. This is in contrast to a “fixed exchange rate” regime

b. Fixed Exchange Rate
A country’s exchange rate regime under which the government or central bank ties the official exchange rate to another country’s currency (or the price of gold). The purpose of fixed exchange rate system is to maintain a country’s currency value within a very narrow band. Also known as pegged exchange rate.

In a fixed exchange – rate system, a country’s central bank typically uses an open market mechanism and is committed at all times to buy and/or sell Its currency at a fixed price in order to maintain its pegged ratio and, hence, the stable value of its currency in relation to the reference to which it is pegged,

c. Managed float regime is the current international financial environment in which exchange rates fluctuate from day to day, but central banks attempt to influence their countries exchange by buying and selling currencies. It is also known as a dirty float.
Managed float exchange rates are determined in the foreign exchange market. Authorities can and do intervene, but are not bound by any intervention rule. Often accompanied by a separate nominal anchor, such as inflation target. The arrangement provides a way to mix market determined creates with stabilizing intervention in a non – rule based system. Its potential drawbacks are that it doesn’t place hard constraints on monetary and fiscal policy. It suffers from uncertainty from reduced credibility, relying on the credibility to monetary authorities. It typically offers limited transparency.
