, Question 1
A firm's demand curve is estimated as Q = 500 - 4P + 0.5I, where Q is
quantity, P is price, and I is consumer income. If P = 50 and I = 2000, what is
the income elasticity of demand?
A. 0.5
B. 1.0
C. 2.0
D. 0.25
Correct Answer: C - 2.0
RATIONALE
Income elasticity = (Q/I)*(I/Q). Q/I = 0.5. At P=250, I=2000,
Q=500-4(250)+0.5(2000)=500-1000+1000=500. Thus elasticity =
0.5*(2000/500)=2.0. Options A, B, and D are incorrect because they
do not match the calculated value.
Question 2
A production function is Q = 10L^0.5 K^0.5. If the wage rate is $20 and the
rental rate of capital is $80, what is the cost-minimizing input combination to
produce 100 units?
A. L=10, K=10
B. L=20, K=5
C. L=5, K=20
D. L=25, K=4
Correct Answer: B - L=20, K=5
Page 2
, RATIONALE
Cost minimization requires MRTS = w/r. MRTS = MPL/MPK =
(5L^{-0.5}K^{0.5})/(5L^{0.5}K^{-0.5}) = K/L. So K/L = 20/80 =
0.25 => K = 0.25L. Also Q=10L^0.5 K^0.5 =100 => L^0.5 K^0.5 =10
=> LK=100. Substitute K=0.25L: L*(0.25L)=100 => 0.25L^2=100 =>
L^2=400 => L=20, K=5. Thus option B is correct. A, C, and D do not
satisfy both conditions.
Question 3
In a Cournot duopoly, market demand is P = 100 - 2Q, where Q = q1 + q2.
Firm 1 has marginal cost MC1 = 10 and Firm 2 has MC2 = 20. What is Firm
1's equilibrium output?
A. 20
B. 25
C. 30
D. 15
Correct Answer: D - 15
RATIONALE
With symmetric marginal costs of 10, each firm's reaction function is
q = (100 - 2q_other - 10)/4 = 22.5 - 0.5q_other. Solving the system
yields q1 = q2 = 15. Thus Firm 1's output is 15. Options A, B, and C
are incorrect because they do not satisfy the Cournot equilibrium
conditions.
Question 4
A firm practices third-degree price discrimination across two markets. Demand
in Market A is P_A = 100 - 2Q_A, and in Market B is P_B = 80 - Q_B.
Marginal cost is constant at $20. What price should the firm charge in Market
A?
A. $60
B. $50
Page 3
, C. $70
D. $40
Correct Answer: A - $60
RATIONALE
Profit maximization in each market: MR = MC. For Market A: MR_A
= 100 - 4Q_A = 20 => 4Q_A = 80 => Q_A = 20. Then P_A = 100 -
2(20) = $60. For Market B: MR_B = 80 - 2Q_B = 20 => 2Q_B = 60
=> Q_B = 30, P_B = 80 - 30 = $50. Thus price in Market A is $60.
Options B, C, and D are incorrect.
Question 5
Which of the following best explains why a firm might experience economies
of scope?
A. Increasing output reduces average cost due to spreading fixed costs.
B. Producing multiple products jointly reduces total cost compared to
separate production.
C. Learning by doing lowers marginal cost as cumulative output
increases.
D. Bulk purchasing of inputs lowers average variable cost.
Correct Answer: B - Producing multiple products jointly reduces
total cost compared to separate production.
RATIONALE
Economies of scope exist when the cost of producing two products
together is less than the cost of producing them separately. Option B
captures this. Option A describes economies of scale, C describes
learning curve effects, and D describes pecuniary economies.

Correct Answer: C - 2.0
RATIONALE
Income elasticity = (Q/I)*(I/Q). Q/I = 0.5. At P=250, I=2000,
Q=500-4(250)+0.5(2000)=500-1000+1000=500. Thus elasticity =
0.5*(2000/500)=2.0. Options A, B, and D are incorrect because they

, RATIONALE
Cost minimization requires MRTS = w/r. MRTS = MPL/MPK =
(5L^{-0.5}K^{0.5})/(5L^{0.5}K^{-0.5}) = K/L. So K/L = 20/80 =
0.25 => K = 0.25L. Also Q=10L^0.5 K^0.5 =100 => L^0.5 K^0.5 =10
=> LK=100. Substitute K=0.25L: L*(0.25L)=100 => 0.25L^2=100 =>
L^2=400 => L=20, K=5. Thus option B is correct. A, C, and D do not
satisfy both conditions.

In a Cournot duopoly, market demand is P = 100 - 2Q, where Q = q1 + q2.
Firm 1 has marginal cost MC1 = 10 and Firm 2 has MC2 = 20. What is Firm

With symmetric marginal costs of 10, each firm's reaction function is
q = (100 - 2q_other - 10)/4 = 22.5 - 0.5q_other. Solving the system
yields q1 = q2 = 15. Thus Firm 1's output is 15. Options A, B, and C

A firm practices third-degree price discrimination across two markets. Demand
in Market A is P_A = 100 - 2Q_A, and in Market B is P_B = 80 - Q_B.

Profit maximization in each market: MR = MC. For Market A: MR_A
= 100 - 4Q_A = 20 => 4Q_A = 80 => Q_A = 20. Then P_A = 100 -

=> Q_B = 30, P_B = 80 - 30 = $50. Thus price in Market A is $60.
Options B, C, and D are incorrect.
