Deck 15: Monopoly

Question 1

The De Beers Diamond company is not worried about differentiating its product from all other gemstones.

Answer 1

False

Question 2

The amount of power that a monopoly has depends on whether there are close substitutes for its product.

Answer 2

True

Question 3

If a product can be produced by a natural monopoly, society will benefit in the form of lower prices if the monopolist is broken up into several smaller firms.

Answer 3

False

Question 4

Monopolists can achieve any level of profit they desire because they have unlimited market power.

Question 5

A patent gives a single person or firm the exclusive right to sell some good or service forever.

Question 6

Even with market power, monopolists cannot achieve any level of profit they desire because they will sell lower quantities at higher prices.

Question 7

When a monopolist increases the quantity that it sells, price decreases, which, all else equal, decreases total revenue; this is called the price effect.

Question 8

Average revenue for a monopoly is the total revenue divided by the quantity produced.

Question 9

A patent gives a single person or firm the exclusive right to sell some good or service for a specific period of time.

Question 10

For a monopoly, marginal revenue is often greater than the price it charges for its good.

Question 11

When a monopolist increases the quantity that it sells, all else equal, total revenue increases, which is called the output effect.

Question 12

The De Beers Diamond company advertises heavily to promote the sale of all diamonds, not just its own. This is evidence that it has a monopoly position to some degree.

Question 13

One characteristic of a monopoly market is that the product is virtually identical to products produced by competing firms.

Question 14

The fundamental cause of monopolies is barriers to entry.

Question 15

The three main sources of barriers to entry are monopoly resources, government regulation, and the firm's production process.

Question 16

If the government deems a newly-invented drug to be truly original, the pharmaceutical company is given the exclusive right to manufacture and sell the drug for 50 years.

Question 17

A natural monopoly has economies of scale for most if not all of its range of output.

Question 18

If the ABC company owns the exclusive rights to mine land in Afghanistan for Lapis Lazuli, a rare stone used in jewelry which is found only in Afghanistan, the company benefits from a barrier to entry.

Question 19

Declining average total cost with increased production is one of the defining characteristics of a natural monopoly.

Question 20

Copyrights and patents are examples of barriers to entry that give firms monopoly pricing powers.

Question 21

During the life of a drug patent, the monopoly pharmaceutical firm maximizes profit by producing the quantity at which marginal revenue equals marginal cost.

Question 22

A monopoly creates a deadweight loss to society because it produces less output than the socially efficient level.

Question 23

A monopolist produces an output level where marginal revenue equals marginal cost and charges a price where marginal cost equals average total cost.

Question 24

Like competitive firms, monopolies choose to produce a quantity in which marginal revenue equals marginal cost.

Question 25

Deadweight loss measures the loss in society's welfare that occurs because a monopolist does not produce the socially efficient level of output.

Question 26

In a monopoly market, the socially efficient quantity of output is typically higher than the profit-maximizing quantity of output for the monopolist.

Question 27

The profit that a monopolist earns represents a loss to society that is measured through deadweight loss.

Question 28

Deadweight loss measures the loss in society's welfare that occurs because a monopolist can earn profits without the concern of new firms entering its industry.

Question 29

The deadweight loss for a monopolist equals one-half of its profits for any given level of output.

Question 30

Like competitive firms, monopolies charge a price equal to marginal cost.

Question 31

The socially efficient quantity is found where the demand curve intersects the marginal cost curve.

Question 32

A monopolist's supply curve is vertical.

Question 33

A monopolist produces where P > MC = MR.

Question 34

A monopolist's profit is equal to (Price - Marginal Cost) × Quantity.

Question 35

At the profit-maximizing quantity of output for a monopolist, average revenue, marginal revenue, and price are all equal.

Question 36

A monopolist does not have a supply curve because the firm's decision about how much to supply is impossible to separate from the demand curve it faces.

Question 37

A monopolist produces where P = MC = MR.

Question 38

A monopolist maximizes profit by producing an output level where marginal cost equals price.

Question 39

A monopoly creates a deadweight loss to society because it earns both short-run and long-run positive economic profits.

Question 40

A monopolist's supply curve is horizontal.

Question 41

Suppose a profit-maximizing monopolist faces a constant marginal cost of $10, produces an output level of 100 units, and charges a price of $50. The socially efficient level of output is 200 units. Assume that the demand curve and marginal revenue curve are the typical downward-sloping straight lines. The monopoly deadweight loss equals $4,000.

Question 42

Price discrimination can increase both the monopolist's profits and society's welfare.

Question 43

Suppose a profit-maximizing monopolist faces a constant marginal cost of $10, produces an output level of 100 units, and charges a price of $50. The socially efficient level of output is 200 units. Assume that the demand curve and marginal revenue curve are the typical downward-sloping straight lines. The monopoly deadweight loss equals $2,000.

Question 44

Antitrust laws give the Justice Department the authority to challenge potential mergers between companies in an effort to safeguard society from monopoly power.

Question 45

Movie theatres charge different prices to different groups of people based on the differing marginal costs that exist from group to group.

Question 46

If the government regulates the price a natural monopolist can charge to be equal to the firm's marginal cost, the government will likely need to subsidize the firm.

Question 47

Suppose a profit-maximizing monopolist faces a constant marginal cost of $20, produces an output level of 100 units, and charges a price of $50. The socially efficient level of output is 200 units. Assume that the demand curve and marginal revenue curve are the typical downward-sloping straight lines. The monopoly deadweight loss equals $1,500.

Question 48

Some companies merge in order to lower costs through efficient joint production.

Question 49

The proper level of government intervention is unclear when dealing with a monopoly.

Question 50

By selling hardcover books to die-hard fans and paperback books to less enthusiastic readers, the publisher is able to price discriminate and raise its profits.

Question 51

A monopolist that can practice perfect price discrimination will not impose a deadweight loss on society.

Question 52

In order for a firm to maximize profits through price discrimination, the firm must have some market power and be able to prevent arbitrage.

Question 53

University financial aid can be viewed as a type of price discrimination.

Question 54

Airlines often separate their customers into business travelers and personal travelers by giving a discount to those travelers who stay over a Saturday night.

Question 55

Price discrimination is prohibited by antitrust laws.

Question 56

Goods that do not have close substitutes have downward-sloping demand curves.

Question 57

A monopolist earns higher profits by charging one price than by practicing price discrimination.

Question 58

If the government regulates the price a natural monopolist can charge to be equal to the firm's average total cost, the firm has no incentive to reduce costs.

Question 59

By offering lower prices to customers who buy a large quantity, a monopoly is price discriminating.

Question 60

A common solution to monopoly in European countries is public ownership.

Question 61

Barriers to entry only exist for monopoly markets.

Question 62

​As long as as a monopolist is able to control the resale of its product, then it can successfully practice price discrimination.

Question 63

​The best option to control the behavior of a natural monopoly is to use public ownership of the monopoly.

Question 64

Which of the following statements is not correct?

A)The government may use antitrust laws to break up an existing company to improve competition.
B)The government may break up a natural monopoly to lower the price charged to customers.
C)Private ownership is typically preferred to public ownership.
D)Sometimes the best strategy is for the government to do nothing about monopoly inefficiency because the "fix" may be worse than the problem.

Question 65

Which of the following statements is correct?

A)Firms with some degree of monopoly power are common, but firms with substantial monopoly power are rare.
B)Firms with some degree of monopoly power are rare, as are firms with substantial monopoly power.
C)Firms with some degree of monopoly power are common, as are firms with substantial monopoly power.
D)Firms with some degree of monopoly power are rare, but firms with substantial monopoly power are common.

Question 66

​

Question 68

Most firms have

A)no monopoly pricing power.
B)some monopoly pricing power.
C)absolute monopoly pricing power.
D)the ability to earn monopoly profits.

Question 69

Government intervention always reduces monopoly deadweight loss.

Question 70

Firms with substantial monopoly power are quite common because many goods are unique.

Question 71

Question 72

Which of the following is the preferred strategy for the government to follow to remedy the inefficient allocation of resources associated with monopolies?

A)preventing mergers through antitrust laws
B)regulating the prices that monopolies can charge
C)doing nothing
D)None of the above strategies is preferred. Each is a viable strategy.

Question 73

The supply curve for a monopolist, in the short run, is defined in the same way as that for a competitive firm: it is the portion of the marginal cost curve above average variable cost.

Question 74

The government may choose to do nothing to reduce monopoly inefficiency because the "fix" may be worse than the problem.

Question 75

​Since monopolists that practice price discrimination generally increase market output, compared to a monopoly that charges a single price, practicing price discrimination generally leads to a smaller deadweight loss.

Question 76

A natural monopoly will always operate in the region of the long run average total cost curve where the cost per unit is constant.
​
​
