NON-COMPETITIVE MARKETS MCQs

Total Questions : 25 | Page 1 of 3 pages
Question 1. The market demand curve for monopolistic competition is flatter than the demand curve for monopoly. State true or false.
  1.    True
  2.    False
  3.    MC=AR=P
  4.    MC=AR >  P
 Discuss Question
Answer: Option A. -> True
:
A
In case of monopolistic competition, the demand is more elastic as competition is more i.e. products have more substitutes. Hence, the demand curve is flatter.
Question 2. See the MC and MR curves for a firm given below and identify the profit-maximizing level of output.
 
See The MC And MR Curves For A Firm Given Below And Identify...
  1.    4
  2.    10
  3.    12
  4.    24
 Discuss Question
Answer: Option B. -> 10
:
B
Profit maximization occurs when MC=MR. This occurs at an output level of 10 units where the MC and MR curves intersect.
Question 3. For a monopoly firm, MR = 50 -5q. At what output level is the TR maximum?
  1.    5
  2.    10
  3.    20
  4.    50
 Discuss Question
Answer: Option B. -> 10
:
B
TR is maximum at the output level where the MR is zero.
505q=05q=50q=10
TR is maximized at an output level of 10.
Question 4. If the price is Rs 10, quantity supplied is 20 and the average total cost is Rs 3, then calculate profit.
  1.    Rs 100
  2.    Rs 140
  3.    Rs 160
  4.    Rs 200
 Discuss Question
Answer: Option B. -> Rs 140
:
B
Profit =(P-ATC)×q=7×20=Rs140
Question 5. Which of the following markets closely resembles a perfectly competitive market?
  1.    Stock market
  2.    Markets for agricultural products
  3.    Markets for petroleum and natural gas
  4.    All of the above
 Discuss Question
Answer: Option B. -> Markets for agricultural products
:
B
Markets for agricultural products like rice, wheat etc resemble perfectly competitive markets because there are a large number of producers, free entry and exit and products are identical.
Question 6. The demand curve for a monopoly firm is p= 80-0.5q. If the MC is constant at Rs 10, find the profit-maximizing level of output.
  1.    35
  2.    50
  3.    70
  4.    80
 Discuss Question
Answer: Option C. -> 70
:
C
Given that demand curve is p= 80-0.5 q
The slope of demand curve = 0.5
Slope of MR curve = 2 × 0.5= 1
The equation of the MR curve is MR = 80-q
Equating MR=MC, we get 80 -q = 10
Hence, the profit-maximizing output is 70
Question 7. The supply curve for a monopolist is 
  1.    upward sloping
  2.    downward sloping
  3.    horizontal
  4.    none of these
 Discuss Question
Answer: Option D. -> none of these
:
D
Monopolists are price makers i.e. they decide the price at which to sell a product. Hence, the concept of the supply curve is not applicable for a monopolist.
Question 8. In the long run, firms under monopoly or oligopoly must only earn normal profits. State true or false.
  1.    True
  2.    False
  3.    horizontal
  4.    none of these
 Discuss Question
Answer: Option B. -> False
:
B
Monopolies and oligopolies have the freedom to adjust prices and hence, their long-run equilibrium profits are non-zero.
Question 9. What is the profit maximization rule for monopolistic competition?
  1.    MC=MR=P
  2.    P >MC = MR
  3.    MC=AR=P
  4.    MC=AR >  P
 Discuss Question
Answer: Option B. -> P >MC = MR
:
B
Profit maximization rule for a monopolistic competition is the same as that of a monopoly.
P >MC = MR
Question 10. Cartels are inherently unstable because ___
  1.    firms in a collusion have the incentive to sell at lower than agreed prices and drive up profits.
  2.    forming cartels and price fixing is illegal
  3.    all firms in the market have to agree to form cartels and when a new firm enters the market, the cartelisation has to happen again.
  4.    All of these
 Discuss Question
Answer: Option D. -> All of these
:
D
All of the listed reasons contribute to the instability of cartels.
