Question

25. The "monopolistic" element of monopolistic competition is due to the fact that

B) firms are spending money on advertising and the extra costs must be recovered.

C) each firm overestimates the capacity it needs when it fails to take into consideration how other firms will respond to the output decisions it makes.

A) with two types of customers.

B) with two sellers.

C) a monopolist engages in first degree price discrimination

D) none of the above

29. Economic efficiency involves

D) none of the above

31. A monopoly will produce the efficient rate of output if it                        

A) engages in perfect price discrimination.

B) engages in no price discrimination

C) engages in third-degree price discrimination.

D) is regulated and average-cost pricing is enforced.

32. Third degree price discrimination                                                                      

A) causes consumer surplus to be eliminated

B) is called third-degree because it works best for firms if products can be resold later on

C) will maximize profits if a firm charges a price in each market segment that equals its marginal cost multiplied by the price elasticity of demand

D) none of the above

34. According to the “Golden Rule” of cost minimization;

A) if one input has a lower marginal product than another, it should not be employed

B) if one input costs more per hour than another, it should not be employed

C) inputs should be employed such that the ratio of their respective prices equals the ratio of their respective marginal products

D) none of the above

35. Under two-part pricing

A) profits are maximized by setting a user charge at a monopoly level

B) profits are maximized by establishing a set-up charge to capture consumer surplus that would have otherwise remained

C) profits are maximized by having the sum of the user charge and the set-up charge be as high as possible

D) none of the above

36. Some consumer surplus remains under each of the following EXCEPT                       

A) two-part pricing with multiple consumers

B) third-degree price discrimination

C) first-degree price discrimination

D) block pricing

37. In the case of an increasing cost industry in which consumer demand has decreased

A) the final, long run price will be higher than the price at the very beginning

B) the final, long run price will be lower than the price that first emerges in the short run after the decrease in demand, but in the short-run the price will become higher than the price at the very beginning

C) cost curves shift downward in the long run as firms exit the industry

D) none of the above

38. Which of the following would contribute to the emergence of an industry characterized by oligopoly?

A) the level of production consistent with minimum efficient scale is very small in comparison to the size of the overall market

B) barriers to entry that most firms would have difficulty overcoming

C) anti-trust laws that prevent most mergers

D) none of the above

39. When a profit-maximizing monopolist sells output in two distinct markets, which of the following is true?

A) Price will be higher in the market in which demand is unit-elastic.

B) Price will be lower in the market with the more elastic demand

C) Price will be equal in each market, as long as there is a constant marginal cost.

D) Price will be lower in the market for which there are fewer substitute goods.

40. With intertemporal price discrimination                                                               

A) each consumer is charged his/her full willingness to pay.

B) groups are charged different prices in accordance with the principles of third-degree price discrimination

C) monopolists capture all the consumer surplus.

D) Both A and C are true.

Answer 1

25. The "monopolistic" element of monopolistic competition is due to the fact that

D) the firm, facing a downward sloping demand curve, has some control over price.
Explanation: In monopolistic competition, there is some consumer loyalty due to product differentiation.

26. In the long run, an industry under monopolistic competition is characterized by excess capacity because         

D) entry occurs until zero profits are made, which implies that each firm is producing to the left of the minimum point of its average cost curve.
Explanation: In the long run, output is produced at the point where demand is tangential to ATC.

27. A duopoly is an industry                                                                                                 

B) with two sellers.

Expalantion: Duo stand for 2 .

28. “Deadweight” loss occurs if

D) none of the above
Deadweight loss is total loss of economic welfare.
