LOS e: Explain the potential gains from monopoly and the regulation of a natural monopoly.

Which of the following is least likely to be considered a reason for the existence of a natural monopoly? Firms:

A) that can maximize profit when price equals marginal cost.

B) that have significant economies of scope.

C) for which average total cost decreases over the entire range of industry demand.

---

Profit maximization occurs when price equals marginal cost in a perfectly competitive industry, not a monopoly. A natural monopoly exists when economies of scale or scope are so significant that total industry production should be produced by only one firm. In this case, average total cost declines over the entire range of demand.

In a natural monopoly:

A) the average total cost of production continually declines with increased output.

B) one firm controls all natural resources.

C) the price charged by a monopolist is determined by the intersection of the demand curve with the marginal cost curve.

---

A monopoly situation in which the average total cost of production continually declines with increased output is called a natural monopoly.

honeycfa

Which of the following statements regarding monopolies is least accurate?

A) Inefficient producers are able to survive.

B) Monopolists will try to get favorable treatment from the government called rent seeking.

C) Due to the law of diminishing returns, natural monopolies exhibit an upward sloping average total cost curve.

---

 

Natural monopolies have economies of scale that are so pronounced their average total cost curve is downward sloping in the region of relevant market demand.

When a regulatory agency requires a monopolist to use average cost pricing, the intent is to produce the quantity where the:

A) marginal revenue curve intersects the marginal cost curve.

B) the market demand curve intersects the average total cost curve.

C) average total cost curve intersects the marginal revenue curve.

---

When a regulatory agency requires a monopolist to use average cost pricing, the intent is to price the product where the average total cost curve intersects the market demand curve. There are problems in using this method, e.g., determining exactly what the average total cost really is.

Natural monopolies exist because they can produce at lower costs with greater output, which means there are economies of scale. Which of the following industries is typically a natural monopoly?

A) Technology.

B) Utilities.

C) Oil.

---

With a natural monopoly average costs of production will be lowest when a single large firm produces the entire output demanded such as a utility.

B) Firms that have significant economies of scope.

Consider the following statements:

Statement 1: “A natural monopoly exists when economies of scale are so pronounced that all of an industry’s demand should be supplied by one firm.”

Statement 2: “Monopoly is characterized by a single seller of a distinct product for which no good substitutes exist.”

Statement 3: “Average cost pricing is a form of regulation that is intended to force monopolists to reduce output to the point where the monopolist’s average total cost curve intersects its marginal cost curve.”

Which of the following best describes the accuracy of these statements?

Statement 1

Statement 2

Statement 3

A) Correct Correct Incorrect

B) Correct Incorrect Correct

C) Incorrect Correct Incorrect

---

Statement 3 is incorrect because average cost pricing attempts to force the monopolist to produce where the average total cost curve intersects the demand curve and to charge a price equal to ATC.

honeycfa

Which of the following describes the regulatory practice of setting prices at a level where the monopoly firm’s average total cost curve intersects the demand curve?

A) Marginal cost pricing.

B) Cost-of-service pricing.

C) Average cost pricing.

---

Under average cost pricing, regulators attempt to force monopolies to reduce prices to where a firm’s average total cost curve intersects the market demand curve. This will increase output and decrease price, increase allocative efficiency, and ensure zero economic profit.

honeycfa

Which of the following is least likely to be considered a reason why regulation of monopolies is not effective?

A) Regulation reduces the incentive for firms to reduce costs.

B) Regulators do not know the firm’s cost structure.

C) Regulation shifts industry demand and increases prices.

---

Regulation is not associated with a shift in industry demand.
