Question 1

Which of the following best describes a monopoly as defined in the study materials?

Accepted Answer

A market with one producer and no close substitutes, where entry is not free.

Question 2

Why is the demand curve facing a monopolist downward sloping, as opposed to the perfectly elastic demand curve in perfect competition?

Accepted Answer

Because the monopolist is the sole seller and must lower price to sell more units.

Question 3

Suppose a monopolist faces the following linear demand curve: $$P = 200 - 0.5Q. $$What is the marginal revenue (MR) function for this monopolist?

Accepted Answer

$$MR = 200 - Q$$

Question 4

Which of the following is NOT a barrier to entry that can create a monopoly?

Accepted Answer

Homogeneous goods.

Question 5

A monopolist is maximizing profit under uniform pricing. Which of the following statements is correct?

Accepted Answer

The monopolist chooses the price and quantity combination where marginal revenue equals marginal cost.

Question 6

If a monopolist increases the price of its product, what happens to the quantity demanded and total revenue?

Accepted Answer

Quantity demanded decreases, and total revenue may increase or decrease depending on elasticity.

Question 7

In the context of monopoly, what does it mean to be a 'price-maker'?

Accepted Answer

The firm can influence the market price by adjusting its output.

Question 8

Which of the following real-world examples best illustrates a natural monopoly?

Accepted Answer

A local water utility company.

Question 9

Consider a monopolist with total cost function $$TC = 50 + 10Q$$ and demand curve $$P = 100 - 2Q. $$What is the profit-maximizing quantity?

Accepted Answer

$$Q = 15$$

Question 10

Which of the following is a likely consequence of monopoly power in a market?

Accepted Answer

Higher prices and lower quantities compared to perfect competition.

Question 11

Why is the marginal revenue (MR) curve for a monopolist always below the demand curve (except at the first unit)?

Accepted Answer

Because the monopolist must lower the price on all units to sell an additional unit.

Question 12

If a monopolist is not able to price discriminate, what is the relationship between price (P) and marginal revenue (MR) at the profit-maximizing output?

Accepted Answer

$$P \u003e MR$$

Question 13

Which of the following is NOT a key assumption of monopoly as described in the study materials?

Accepted Answer

Entry into the market is free and easy.

Question 14

A monopolist faces the demand curve $$P = 120 - Q$$ and has constant marginal cost $$MC = 40. $$What is the profit-maximizing price?

Accepted Answer

$$P = 80$$

Question 15

Which of the following best explains why monopolists are often associated with negative public perception?

Accepted Answer

They tend to charge higher prices and supply lower quantities than competitive markets.
