Describe how government is involved in creating amonopoly. Why might the government create one? Give an example.ANS:The government can create a monopoly by giving a single firm the exclusive right to produce some good. Monopolies are created for many reasons. When an industry is characterized by high fixed costs, a single firm can usually supply the entire market at a lower cost than having multiple firms in the industry. Examples include most utility companies. The government also grants sole ownership of inventions through patent laws in order to help eliminate the market failure that is likely to otherwise occur in the markets for those goods. Patents encourage creativity and research and development.DIF: 2 REF: 15-1 NAT: Analytic LOC: MonopolyTOP: Patents | Regulation MSC: Applicative2. What is the defining characteristic of a natural monopoly?

Discuss the context in which your electricity provider is a monopolist. Is this characterization universally applicable?Explain your answer.ANS:In this case, the firms are monopolists in the short run when consumers are unable to change their "home heating" systems. In the long run, consumers can change from electric appliances to natural gas appliances and thus lessen the monopoly power of utility providers. As long as consumers are able to substitute, in the long run the monopoly pricing power is reduced.DIF: 3 REF: 15-2 NAT: Analytic LOC: MonopolyTOP: Monopoly MSC: Analytical4. There has been much discussion of deregulating electricity and natural gas delivery companies in the UnitedStates. Discuss the likely effect of deregulation on prices in these two industries.ANS:If deregulation leads to increased competition, then production and prices should move toward the competitive equilibrium. If deregulation does not lead to increased competition, then the monopoly production and price outcome is likely. The success of deregulation movements hinges on their ability to use markets to promote competitive market outcomes. If the industry is characterized by economies of scale, deregulation may worsen rather than improve the market as costs and prices could rise if more than one firm supplies output to the market.

Explain how a profit-maximizing monopolist chooses its level of output and the price of its goods.ANS:A profit-maximizing monopolist produces the output levelwhere marginal revenue equals marginal cost and charges the corresponding price from the market demand curve.

Graphically depict the deadweight loss caused by a monopoly. How is this similar to the deadweight loss fromtaxation?ANS:A profit-maximizing monopolist will choose to produce Q0 units of output and sell at price P0. However, marginal cost is MC0.

What is the deadweight loss due to profit-maximizing monopoly pricing under the following conditions: The price charged for goods produced is $10. The intersection of the marginal revenue and marginal cost curves occurs where output is 100 units and marginal revenue is $5. The socially efficient level of production is 110 units. The demand curve is linear and downward sloping, and the marginal cost curve is constant.ANS:1/2*(110-100)*($10-$5) = $25DIF: 3 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: Deadweight loss MSC: Applicative8. Assume that a monopolist decides to maximize revenue rather than profit. How does this operating objective change the size of the deadweight loss? If you are a "benevolent" manager of a monopoly firm and areinterested in reducing the deadweight loss of monopoly, should you maximize profits or maximize revenue?Explain your answer.ANS:A revenue maximizer operates where MR = 0. This solution moves the monopolist closer to the socially optimal competitive outcome and reduces deadweight loss. Revenue maximization is potentially a more "socially" optimal objective for monopoly markets than profit maximization.DIF: 3 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: T otal revenue MSC: Analytical9. One example of price discrimination occurs in the publishing industry when a publisher initially releases anexpensive hardcover edition of a popular novel and later releases a cheaper paperback edition. Use thisexample to demonstrate the benefits and potential pitfalls of a price discrimination pricing strategy.ANS:The answer should address the three basic lessons of price discrimination. First, price discrimination is a rational strategy that can lead to higher monopoly profits. Second, price discrimination requires an ability to separate customers according to their willingness to pay. Third, price discrimination can raise economic welfare.DIF: 2 REF: 15-4 NAT: Analytic LOC: MonopolyTOP: Price discrimination MSC: Analytical。

Note that a monopolist charges a price that exceeds marginal cost, unlike a competitive firm, for which price equals marginal cost.DIF: 2 REF: 15-2 NAT: Analytic LOC: MonopolyTOP: Profit maximization MSC: AnalyticalChapter 15/Monopoly 1007 6. Graphically depict the deadweight loss caused by a monopoly. How is this similar to the deadweight loss fromtaxation?ANS:A profit-maximizing monopolist will choose to produce Q0 units of output and sell at price P0. However, marginal cost is MC0. This is identical to the deadweight loss of taxation when the tax forces a wedge between market price and marginal cost.DIF: 2 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: Deadweight loss MSC: Analytical7. What is the deadweight loss due to profit-maximizing monopoly pricing under the following conditions: Theprice charged for goods produced is $10. The intersection of the marginal revenue and marginal cost curves occurs where output is 100 units and marginal revenue is $5. The socially efficient level of production is 110 units. The demand curve is linear and downward sloping, and the marginal cost curve is constant.ANS:1/2*(110-100)*($10-$5) = $25DIF: 3 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: Deadweight loss MSC: Applicative8. Assume that a monopolist decides to maximize revenue rather than profit. How does this operating objectivechange the size of the deadweight loss? If you are a "benevolent" manager of a monopoly firm and areinterested in reducing the deadweight loss of monopoly, should you maximize profits or maximize revenue?Explain your answer.ANS:A revenue maximizer operates where MR = 0. This solution moves the monopolist closer to the socially optimal competitive outcome and reduces deadweight loss. Revenue maximization is potentially a more "socially" optimal objective for monopoly markets than profit maximization.DIF: 3 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: Total revenue MSC: Analytical9. One example of price discrimination occurs in the publishing industry when a publisher initially releases anexpensive hardcover edition of a popular novel and later releases a cheaper paperback edition. Use thisexample to demonstrate the benefits and potential pitfalls of a price discrimination pricing strategy.ANS:The answer should address the three basic lessons of price discrimination. First, price discrimination is a rational strategy that can lead to higher monopoly profits. Second, price discrimination requires an ability to separate customers according to their willingness to pay. Third, price discrimination can raise economic welfare.DIF: 2 REF: 15-4 NAT: Analytic LOC: MonopolyTOP: Price discrimination MSC: Analytical1008 Chapter 15/Monopoly10. What are the four ways that government policymakers can respond to the problem of monopoly?ANS:First, the government can try to make monopolized industries more competitive by using the power of antitrust laws. Second, the government can regulating the behavior of monopolies, which usually occurs with natural monopolies. Third, the government can own and run a monopoly. Four, the government can do nothing.DIF: 2 REF: 15-5 NAT: Analytic LOC: MonopolyTOP: Government MSC: Interpretive11. Give some examples of the benefits and costs of antitrust laws.ANS:Benefits include promoting competition by preventing mergers and breaking-up companies. Costs are that they may increase cost of operating if they restrict synergy mergers.DIF: 2 REF: 15-5 NAT: Analytic LOC: MonopolyTOP: Antitrust MSC: Interpretive12. In many countries, the government chooses to "internalize" the monopoly by owning monopoly providers ofgoods and services. (In some cases these firms are "nationalized," and the government actually buys orconfiscates firms that operate in monopoly markets). What would be the advantages and disadvantages of such an approach to ensure that the "best interest of society" is promoted in these markets? Explain your answer. ANS:As long as the government "owner" pursues a production and pricing policy that approaches a competitive outcome, social well-being can be enhanced. In this case the government ownership would benefit society. However, in most cases, government owners operate much like private sector monopolists. The political economy of government institutions does not ensure that government owners will pursue socially optimal policy. Also, governments have no incentive to reduce costs or innovate.DIF: 3 REF: 15-5 NAT: Analytic LOC: MonopolyTOP: Government MSC: Analytical13. Why might economists prefer private ownership of monopolies over public ownership of monopolies?ANS:The private monopolist is governed by the market. Even though the market solution is sub-optimal, it may be better than outcomes generated by publicly owned monopolies. Publicly owned monopolies may restrict output to levels below the private market outcome and thus generate an even lower level of social surplus than a privateprofit-maximizing monopolist.Private owners have an incentive to minimize cost as long as they reap benefits in the form of higher profits. Government bureaucrats have no incentive to reduce costs. The losers are customers and taxpayers, whose only recourse is the political system.DIF: 2 REF: 15-5 NAT: Analytic LOC: MonopolyTOP: Monopoly MSC: Analytical14. One solution to the problems of marginal-cost pricing of a regulated natural monopolist is average cost pricing.In this model, the monopolist is allowed to price its production at average total cost. How does average-cost pricing differ from marginal-cost pricing? Does this solution maximize social well-being?ANS:Under average-cost pricing, the monopolist earns zero economic profits, but average-cost pricing does not ensure a socially optimal market solution. Under marginal-marginal cost pricing, the monopolist cannot cover its total costs, so it will earn negative economic profits.
