Briefly explain the goals of macroeconomics.
Explain through a figure how a consumer is in equilibrium under the ordinal utility (indifference curve) analysis.
With the help of the following information on output (Q), short-run total fixed cost (TFC), and short-run total variable cost (TVC), compute short-run (i) total cost (TC), (ii) average fixed cost (AFC), (iii) average variable cost (AVC), (iv) average cost (AC), and (v) marginal cost (MC):
Q (in units) | 1 | 2 | 3 | 4 | 5 | 6 |
TFC (Rs.) | 120 | 120 | 120 | 120 | 120 | 120 |
TVC (Rs.) | 60 | 80 | 90 | 110 | 150 | 240 |
If the quantity supply of a commodity x (Q x ) rises from 400 units to 1200 units as its price (P x ) rises from Rs. 200 per unit to Rs. 400 per unit, then (i) compute the price elasticity of supply (e s ) and, (ii) interpret this result.
Derive a short-run supply curve of a firm under the market of perfect competition.
Briefly explain the concepts and types of balance of trade and balance of payment.
Using the marginal cost-and-marginal revenue (MC-MR) approach and an appropriate figure, explain how the monopolist reaches a short-run equilibrium.
Attempt any TWO questions
[2x10=20]From the table given below, (i) compute the income elasticity of demand (E QM ) for a commodity x for the movement from points A to B, B to C, C to D, D to E, and E to F; and (ii) also state the nature of this commodity x based on the values and signs taken by this e y at different levels of income.
Table 1
Units of commodities (x & y) | 0 | 1 | 2 | 3 | 4 | 5 |
TUₓ (in units): | 0 | 5 | 9 | 12 | 14 | 15 |
TUᵧ (in units): | 0 | 6 | 11 | 15 | 18 | 20 |
From the following data in Table 2, compute these four concepts of national income by using the Expenditure Method:
(a) GDPₘₚ,
(b) GNPₘₚ,
(c) NNPₘₚ, and
(d) NNP𝒻𝒸 (= NI)
Table 2
Components for Computing the Four Concepts of National Income by Expenditure Method
Components | Rs. (in billion) |
C | 350 |
I | 130 |
G | 60 |
Xₙ | -10 |
Nᵧ | 10 |
D | 50 |
Tₙ | 70 |
I = Private Investment Expenditure;
G = Government Expenditure;
Xₙ = X - M = Net Exports;
X = Exports;
M = Imports;
Nᵧ = Net Factor Income from Abroad;
D = Depreciation;
Tₙ = Net Indirect Tax = Indirect Tax - Subsidies;
GDPₘₚ = Gross Domestic Product at Market Pricev
GNPₘₚ = Gross National Product at Market Price
NNPₘₚ = Net National Product at Market Price
NNP𝒻𝒸 = Net National Product at Factor Cost;
NI = National Income
