4 In an imperfectly competitive market, if the Total Revenue is maximum, Marginal Revenue will be ...................... 1
5 State and discuss any two factors that will shift the Production Possibility Frontier (PPF)to the right.
Draft a hypothetical schedule for a straight line Production Possibility Curve. 3
6 Giving reason, state the impact of each of following on demand curve of a normal good ‘X’ if
i) Price of its complementary good falls.
ii) News reports claims that consumption of product X has harmful effect on human health.
iii) Income of consumer increases, 3
7 a. Arrange the following coefficients of price elasticity of demand in ascending order: -0.87, -0.53, -3.1, -0.80, 1
b. Comment upon the degree of elasticity of demand for commodity X,if the price of the commodity falls from 28 per unit to 23 per unit and its quantity demanded rises from 50 units to 100 units. 3
8 What is meant by Price Floor? Discuss in brief, any one consequence of imposition of floor price above equilibrium price with help of a diagram.
How is the price of a commodity determined in a perfectly competitive market? Explain with help of a diagram. 4
9 Explain how the following factors affect the supply of the commodity (any two)
a) Price of factor inputs b) State of technology c) Government taxation Policy 4
10 a) A consumer, Mr Aman is in state of equilibrium consuming two goods X and Y, with given prices Px and Py . What will happen if ? 2
b) Identify which of the following is not true for the Indifference Curves theory. Give valid reasons for choice of your answer: 4
a. Lower indifference curve represents lower level of satisfaction.
b. Two indifference curves can intersect each other.
c. Indifference curve must be convex to origin at the point of tangency with the budget line at the consumer’s equilibrium.
d. Indifference curves are drawn under the ordinal approach to consumer equilibrium.
A consumer has total money income of 500 to be spent on two goods X and Y with prices of 50 and 10 per unit respectively. On the basis of the given information, answer the following questions:
a. Give the equation of the budget line for the consumer.
b. What is the value of slope of the budget line?
c. How many units can the consumer buy if he is to spend all his money income on good X?
d. How does the budget line change if there is a 50% fall in price of good Y?
11 a) Why is Total Variable Cost curve inverse S- shaped?
b) What is Average Fixed Cost of a firm? Why is an Average Fixed Cost Curve a rectangular Hyperbola? Explain with help of a diagram.
12 Suppose the value of demand and supply curves of a Commodity-X is given by the following two equations simultaneously: Qd = 200 –10p Qs = 50 + 15p
i) Find the equilibrium price and equilibrium quantity of commodity X.
ii) Suppose that the price of a factor inputs used in producing the commodity has changed, resulting in the new supply curve given by the equation Qs’ = 100 + 15p Analyse the new equilibrium price and new equilibrium quantity as against the original equilibrium price and equilibrium quantity. 6
