Question 1

Which of the following best explains why a monopolistically competitive firm faces a downward-sloping demand curve?

Accepted Answer

Because the firm sells a differentiated product, so some customers are willing to pay more for its unique features.

Question 2

Suppose Blue Bottle Coffee can sell 5 coffees at $4 each or 6 coffees at $3.50 each. What is the marginal revenue of selling the 6th coffee?

Accepted Answer

$$MR = (Total\ Revenue\ at\ Q=6) - (Total\ Revenue\ at\ Q=5) = (6 	imes 3.50) - (5 	imes 4.00) = 21.00 - 20.00 = 1.00$$

Question 3

A monopolistically competitive firm maximizes profit in the short run by producing the quantity where:

Accepted Answer

$$MR = MC$$

Question 4

In the long run, what happens to the economic profits of firms in a monopolistically competitive market?

Accepted Answer

Firms earn zero economic profit as new firms enter and drive down demand for existing firms.

Question 5

Which of the following is NOT a characteristic of monopolistic competition?

Accepted Answer

Firms sell identical products

Question 6

Why does a monopolistically competitive firm have excess capacity in the long run?

Accepted Answer

Because it produces less than the output that minimizes average total cost.

Question 7

Which of the following best describes the difference in efficiency between perfect competition and monopolistic competition in the long run?

Accepted Answer

Perfect competition is both productively and allocatively efficient, while monopolistic competition is neither.

Question 8

Suppose a monopolistically competitive firm is currently producing where $P > ATC$. What will likely happen in this market in the long run?

Accepted Answer

New firms will enter, reducing demand for existing firms until $P = ATC$ and economic profit is zero.

Question 9

Which of the following strategies can help a monopolistically competitive firm maintain economic profit in the long run?

Accepted Answer

Continuously differentiating its product and reducing costs below competitors.

Question 10

If a monopolistically competitive firm wants to show profit on a graph, which area represents profit?

Accepted Answer

The rectangle with height $(P - ATC)$ and length $Q$ at the profit-maximizing quantity.

Question 11

Which of the following is a real-world example of product differentiation in monopolistic competition?

Accepted Answer

A coffee shop offering unique blends and direct trade beans.

Question 12

What is the primary role of advertising for a monopolistically competitive firm?

Accepted Answer

To increase demand and differentiate its product from competitors.

Question 13

In the context of monopolistic competition, what is 'brand management'?

Accepted Answer

The actions of a firm intended to maintain the differentiation of a product over time.

Question 14

Suppose a monopolistically competitive firm is making a loss in the short run. What is the firm's best option?

Accepted Answer

Continue operating if $P \geq AVC$ and try to minimize losses.

Question 15

Which of the following equations correctly represents the profit-maximizing condition for any firm that can adjust output marginally?

Accepted Answer

$$MC = MR$$

Question 16

Why does the demand curve for a monopolistically competitive firm become more elastic in the long run?

Accepted Answer

Because consumers have more substitutes as new firms enter the market.

Question 17

Which of the following best describes allocative efficiency?

Accepted Answer

Producing all goods up to the point where marginal benefit equals marginal cost.

Question 18

A monopolistically competitive firm is currently producing where $MC < MR$. What should the firm do to maximize profit?

Accepted Answer

Increase output until $MC = MR$.

Question 19

Which of the following is a plausible reason why consumers might prefer monopolistic competition over perfect competition?

Accepted Answer

Consumers value product variety and differentiation, even at a higher price.

Question 20

If a monopolistically competitive firm wants to avoid zero economic profit in the long run, which of the following is most effective?

Accepted Answer

Continuously innovating and maintaining strong brand loyalty.
