Accepted Answer

$40

Because the monopolist must lower the price on all units to sell more, reducing additional revenue.

Question 8

In the market for cable subscriptions, if the monopolist increases the number of subscribers from 2 to 3 and total revenue rises from $$120 to 150$$, what is the average revenue at Q = 3?

Accepted Answer

The firm earns less revenue per unit sold because of the price decrease.

Question 10

If a monopolist faces the demand curve $$P = 80 - 10Q$$, what is the total revenue function?

Accepted Answer

$$TR = 80Q - 10Q^2$

Question 11

Which of the following is a consequence of the output effect for a monopolist?

Accepted Answer

The firm earns more revenue because it sells more quantity at the lower price.

Question 12

Question 13

If a monopolist’s marginal revenue is negative, what does this imply about total revenue?

Accepted Answer

Total revenue is decreasing.

Question 14

Which statement is true regarding the elasticity of a monopolist’s demand curve compared to the market demand curve?

Accepted Answer

A monopolist’s demand curve is the same as the market demand curve.

Question 15

If a monopolist faces the demand curve $$P = 80 - 10Q$$, what is the marginal revenue function?

Accepted Answer

$$MR = 80 - 20Q$$

Question 16

Which of the following best explains why barriers to entry are important for monopoly power?

Accepted Answer

They prevent new firms from entering, allowing the monopolist to maintain market power.

Question 17

If a monopolist’s average revenue at Q = 4 is $$40, and its marginal revenue for the 4th unit is 20$$, what does this indicate about the relationship between AR and MR?

Accepted Answer

Average revenue is greater than marginal revenue.

Question 18
