Question 1

Which of the following is NOT a typical barrier to entry that can lead to monopoly power?

Accepted Answer

Perfect information among consumers

Question 2

Suppose a monopoly faces the demand function $$P = 700 - 2q$$ and has a marginal cost $$MC = 6q. $$What is the profit-maximizing quantity?

Accepted Answer

$$q = 70$$

Question 3

For a monopoly, which of the following relationships always holds at the profit-maximizing output?

Accepted Answer

$$MR = MC$$

Question 4

Why does a monopoly's demand curve coincide with the market demand curve?

Accepted Answer

Because the monopoly is the only seller in the market

Question 5

If a monopoly sets a price above marginal cost ($$P \u003e MC$$), what does this imply about allocative efficiency?

Accepted Answer

The monopoly is allocatively inefficient because the value to consumers of the last unit exceeds the cost of production

Question 6

Accepted Answer

Question 8

Accepted Answer

The firm must produce at minimum efficient scale

Question 9

If a monopoly faces the demand curve $$P = 700 - 2q$$ and chooses $$q = 70$$, what is the price charged to consumers?

Accepted Answer

$$P = 560$$

Question 10

Which of the following best describes third-degree (multi-market) price discrimination?

Accepted Answer

Charging different prices to different market segments based on observable characteristics

Question 11

Accepted Answer

Question 14

Which of the following is a potential consequence of price matching (low price guarantee) policies?

Accepted Answer

They can facilitate collusion and reduce price competition

Question 15

If a monopoly faces an average total cost function $$ATC = \frac{8000}{q} + 3q$$ and produces $$q = 70$$ units, what is the average total cost?

Accepted Answer

$$ATC = 117$$

Question 16

Which of the following is true about perfect (first-degree) price discrimination?

Accepted Answer

The firm charges each consumer their exact willingness to pay

Question 17

Which of the following is a federally regulated industry in Canada where monopoly or near-monopoly is common?

Accepted Answer

Rail transportation

Question 18

Suppose a monopoly's profit is given by $$\pi = (P - ATC) 	imes q. If$$ $$P = 560$$, $$ATC = 117$$, and $$q = 70$$, what is the total profit?

Accepted Answer

$$\pi = 16,550$$

Question 19

Which of the following is a reason why monopolies are considered inefficient?
