Question 2

Suppose there are 1,000 firms in a market, and market demand has a price elasticity of 0.5. Initially, all firms produce the same output and the market price is $5. One firm then decides to double its output. By how much will price change? Show your work.

Question 4

On a monopoly diagram showing demand, marginal revenue, marginal cost, and average total cost, which of the following cannot be illustrated?

Accepted Answer

A monopoly diagram can illustrate demand, marginal revenue, marginal cost, and average total cost because they are all related to revenue and cost. However, fixed costs are not illustrated on the diagram because they do not change with output level.

Question 5

Why is the marginal revenue curve for a monopoly steeper than its demand curve?

Accepted Answer

The answer of Why is the marginal revenue curve for...

Question 6

A monopoly will expand output until total revenue is maximized.

Accepted Answer

A monopoly will expand output until marginal revenue equals marginal cost, not necessarily when total revenue is maximized. This is the profit-maximizing condition for monopolies.

Question 7

When we say that a monopoly has market power, does it mean that the monopoly can produce and charge any amount it wants? Explain.

Accepted Answer

The answer of When we say that a monopoly has...

Question 10

Exhibit 10-2 
-To ascertain the profit-maximizing price on a monopoly diagram, one must first determine output by finding where

Accepted Answer

The profit-maximizing price on a monopoly diagram is determined by finding the point where marginal cost and marginal revenue intersect, and then extending upward to the demand curve to determine the price on the vertical axis. This is because the profit-maximizing quantity will be where marginal cost equals marginal revenue, but the price is determined by the demand curve at that quantity. Option A is incorrect as it suggests doubling the output to determine price, which is not accurate. Option B is incorrect as it suggests using demand instead of marginal revenue, which can be different. Option D is incorrect as it suggests looking at the point of intersection on the vertical axis, which is also not accurate. Option E is incorrect as it suggests using the horizontal axis, which is not relevant for determining price.

Question 11

A profit-maximizing monopoly produces at the point at which marginal cost equals marginal revenue, while a profit-maximizing competitive firm produces at the point at which marginal cost equals price.

Accepted Answer

This statement is true. Monopolies have market power and can influence the price of their product, so they will produce where their marginal revenue equals marginal cost to maximize profit. Competitive firms, on the other hand, are price takers and must accept the market price, so they will produce where their marginal cost equals the market price to maximize profit.

Question 12

To maximize profits, both monopolies and competitive firms must produce at the point at which price equals marginal cost.

Accepted Answer

Monopolies maximize profits by producing at the point where marginal revenue equals marginal cost, not where price equals marginal cost. In contrast, competitive firms produce at the point where price equals marginal cost.

Question 13

In order to maximize profit, a monopoly will set output so that marginal revenue equals marginal cost and will charge a price equal to marginal revenue.

Accepted Answer

A monopoly maximizes profit by setting output where marginal revenue equals marginal cost, but it will charge the highest price consumers are willing to pay for that quantity, which is typically above marginal revenue.

Question 14

When a monopoly maximizes profits, it produces at an output level at which marginal revenue exceeds marginal cost.

Accepted Answer

When a monopoly maximizes profits, it produces at an output level at which marginal revenue equals marginal cost, not exceeds it.

Question 15

On a graph of monopoly, the profit-maximizing output level is determined by noting where the ____ and ____ curves cross.

Accepted Answer

The profit-maximizing output level for a monopoly is determined by producing where marginal revenue (MR) equals marginal cost (MC). Therefore, the answer is D, where the marginal revenue and marginal cost curves cross.

Question 16

If a monopoly charges a price equal to its marginal cost, then it must be the case that the firm has

Accepted Answer

In a monopoly, charging a price equal to marginal cost does not guarantee maximum profits, as monopolies typically maximize profits by setting prices above marginal cost. The actual financial outcome (profit or loss) depends on the firm's cost structure relative to the price.

Question 17

Exhibit 10-2 
-Refer to Exhibit 10-2. Calculate marginal revenue for the second, third, and fourth unit of output.

Accepted Answer

-Refer to Exhibit 10-2. Calculate...

Question 18

To maximize profits, a monopoly produces at ____ and a competitive firm produces at ____.

Accepted Answer

A monopoly maximizes profits by producing the quantity where marginal revenue equals marginal cost, and then sets the price at the point on the demand curve that corresponds to that quantity. A competitive firm also produces where marginal cost equals marginal revenue, but it sells at the market price, which is equal to marginal cost in a competitive market. Therefore, the monopoly produces less output and charges a higher price than a competitive firm would.

Question 19

A profit-maximizing monopoly might choose to produce anywhere along a straight-line market demand curve.

Accepted Answer

A profit-maximizing monopoly will produce at the quantity where marginal cost equals marginal revenue, not just anywhere along the demand curve. This specific quantity maximizes the difference between total revenue and total cost.

Question 20

Which of the following statements is false?

Accepted Answer

A monopoly maximizes profit where marginal revenue equals marginal cost, not where price equals marginal cost. This is due to the downward-sloping demand curve a monopoly faces, which means that to sell more units, the price must decrease, affecting the revenue for all units sold.
