CHAPTER 17PROMOTING MORE EFFICIENT MARKETS

I. CHAPTER OVERVIEW

Government has three major roles to play in supporting a modern domestic economy: maintain efficiency,

promote macroeconomic stability and growth, and establish a fair distribution of income. This chapter

concentrates on one of government’s primary challenges in exercising its efficiency role—performing a

watchdog function to prevent excessive abuse of market power. Also, the chapter focuses your attention on the

two major tools employed by the U.S. government to put some “teeth” into its careful monitoring of business

activity: regulation and antitrust activity.

Regulation is often employed when economies of scale are so significant in a production process that a

monopoly is the only efficient solution. Government agencies are organized to monitor the behavior of the

monopolist and to protect the interests of consumers. Antitrust legislation is designed to prevent monopolies

from forming and to attack anticompetitive abuses. The Sherman Antitrust Act and the Clayton Act form the

backbone of antitrust policies; the Federal Trade Commission Act established the FTC as the agency in charge

of monitoring and enforcing the legislation. Of course, as with any laws, the courts ultimately interpret their

meaning, and a century of legal precedent defines the meaning of these statutes.

II. LEARNING OBJECTIVES

IV. SUMMARY AND CHAPTER OUTLINE

This section summarizes the key concepts from the chapter.

A. Business Regulation: Theory and Practice

1. In the United States, regulation is the most popular mechanism with which governments at all levels

protect their citizens from potential abuses of market power, particularly when a natural monopoly is under

scrutiny. Regulation, in its broadest context, includes all rules and laws designed to change or control the

operation of an economic enterprise. There are, in fact, two major categories within that context: economic and

social. Economic regulation can be accomplished by controlling prices, production, standards, and exit and

entry conditions. Social regulation is directed at correcting (negative) externalities.

2. There are several reasons to regulate industry. First, government may want to contain market power and

encourage competition in markets. However, when natural monopolies exist, regulatory agencies are

established to protect consumer interests while allowing the monopoly to operate. Second, information failures

may need to be remedied. In some cases, consumers may have insufficient information on products. Before

the government began to take on this task, the markets cried out, “Let the buyer beware!”—implying that it was

the consumer’s responsibility to make sure that products were safe and effective. Now the government protects

consumers by overseeing the production and distribution of many products, from food to infant car seats.

Third, government may want to diminish the severity of externalities. For example, the Environmental

Protection Agency is a regulator whose main activity is to design and enforce pollution control strategies.

Finally, government may choose to step into an industry when the regulators have been “captured” by the

regulated. This happens when the regulators actually begin to protect the firm’s best interest rather than the

consumer’s.

3. The next logical question is, how do regulators set industrial standard? Several alternative strategies exist.

With average-cost pricing, regulated firms are allowed to set price equal to the average total costs of

production. That is, the firm takes all its costs and distributes them to each product sold. This brings them to

a solution that is similar to the long-run perfectly competitive solution that has firms producing at minimum

average total costs.

With marginal-cost pricing, the firm is restricted to setting price equal to marginal cost. This again brings

them to a solution that is similar to perfect competition. However, particularly when economies of scale are

significant, this may lead to losses for the firm. For example, many municipal transportation systems exist as

regulated natural monopolies. (Running several subway systems in the same city hardly seems practical.)

Equity considerations imply that these companies hold their prices to a bare minimum as a service to

commuters and working people. Because these firms cannot generate enough revenues to cover costs at this

price, they are often subsidized by the city government.

291

4. For the past two decades, a significant trend toward deregulation has been spreading across the economy.

From airlines to trucking to banking to electricity, many industries have shed the yoke of regulation and

entered the world of free competition. Most of these industries have emerged stronger and more competitive

than they were under regulation.

B. Antitrust Policy

1. Antitrust policy exists to limit the excesses of imperfect competition. Unregulated monopoly power

allows firms to operate at socially inefficient levels, charging too much for too little product. Monopolists

charge a price that is greater than marginal cost, and often greater than average costs, allowing them to earn

economic profits into the long run. This means that the monopoly solution yields a distribution of resources

that is not allocatively efficient.

Imperfect competition can emerge due to the existence of economies of scale. If the technology in an

industry is such that output can be produced efficiently only when a single firm exists, we have a natural

monopoly.

2. Of course, antitrust policy is written with full knowledge that imperfect competition has both a good and a

bad side. Unbridled exploitation of market power can, on the one hand, depress output and generate excessive

prices and profits. On the other hand, however, there do exist economies of scale that should not be sacrificed

simply for the sake of having many firms instead of few. There is, moreover, a demonstrable correlation

between market concentration and research into discovery and development of new products and new processes.

In light of this dichotomy of properties, it is the primary lesson of this chapter that antitrust activity should (1)

keep the barriers to competition low, (2) tolerate bigness when size is determined by technology, and (3) be

vigilant against anticompetitive practices whenever they occur.3. The three most significant pieces of antitrust legislation in the United States are the Sherman Antitrust Act,the Clayton Act, and the Federal Trade Commission Act. The Sherman Act declares contracts, combinations,and conspiracies in restraint of trade illegal and further states that attempting to monopolize is illegal. TheClayton Act outlines specific anticompetitive behaviors that are illegal, such as price discrimination, tyingcontracts, and interlocking directorates. The Clayton Act also limits corporate mergers that would lessencompetition; horizontal mergers are the most troublesome in this regard. The FTC Act established acommission whose duty is to prohibit “unfair methods of competition” and to warn against anticompetitiveactivity.

4. The application of these antitrust laws is not an easy task. It is often difficult to know if any illegal

behavior exists or to determine exactly what a firm’s intent might be. Thus, on the basis of conduct, it is hard

to know whether or not firms are behaving illegally. In addition, it is often difficult to know exactly how to

define a market or how to define competitors. For example, consider the automobile industry. Is it

oligopolistic, consisting of just three big firms (Ford, Chrysler, GM) in the United States, or is it perfectly

competitive, consisting not only of Ford, Chrysler, and GM but also of Honda, Toyota, BMW, Mazda, etc.?

How do we define markets, and, once we define them, how can we describe the behavior of firms relative to one

another? On the basis of structure, it is hard to know whether or not firms are operating in an illegal fashion.

5. Recent antitrust activity has, in fact, focused on promoting efficiency in business practices and not on

attacking “bigness” per se. The notion underlying this concentration on conduct rather than structure, in an

economy that is facing increasing competition from around the world, is that collusive agreements that try to

fix prices are the most troublesome source of inefficiency. Large firms that can exploit decreasing costs as they

compete internationally can be a source of economic strength as long as they do indeed compete.

V. HELPFUL HINTS

1. Figure 17-2 in your text is complicated, so we have reproduced it here as Figure 17-1. First, notice the

shape and position of the average and marginal cost curves. Because they are everywhere downward-sloping,

this looks like a natural monopoly. The larger the firm gets, the lower its per unit costs. Given a market

demand and marginal revenue curve, the profit-maximizing firm will produce where marginal cost is equal to

marginal revenue and set the highest price it possibly can. This leads to PM and QM as industry price and

output.

292

Figure 17-1

Notice further the inefficiencies inherent in this solution. At QM price is greater than average costs, and it is

greater than marginal costs. This opens the door to regulators, who would like to make some adjustments.

Remember that regulators, in theory, are charged with the duty of protecting consumer interests. This means

they should be fighting to establish prices and output levels that come closer to the competitive ideal.

Average-cost pricing moves in that direction by setting price equal to average costs, allowing the firm to cover

its opportunity costs (R). Marginal-cost pricing often pushes prices below the firm’s average costs, forcing the

firm to incur a loss (I). No monopolist will remain in business given this sort of price, unless they are

subsidized by another government agency.

2. When an industry is deregulated, several events may occur. First, supply might increase as the number of

competing firms increases. (Examples include telephone service and airlines.) This increase in supply should

lower prices for consumers. Along with this increase in supply comes increased competition, which often takes

the form of advertising. Advertising may increase consumer demand, expanding the size of the market for all

competitors. This chain of events seems to reflect both the market for telephone service and the market for

airline travel. Deregulation led to tremendous increases in supply, followed by a barrage of advertising as

competitors scrambled for market share. The resulting increase in demand has enlarged opportunities for all

firms.

3. There are many reasons for firms to pursue conglomerate mergers. One of the most appealing has to do

with risk and uncertainty. A firm that acquires subsidiaries in other industries is able to spread its risk across a

greater number of options, limiting the uncertainty it faces in the marketplace. For example, Philip Morris, a

large producer of cigarettes, purchased the Kraft food chain several years ago. As the market for cigarettes

became increasingly risky, the firm began searching for ways to diversify its holdings. It achieved this

diversification, in part, by purchasing relatively safe product lines.

VII. PROBLEM SOLVING

The following problems are designed to help you apply the concepts that you learned in this chapter.


1. Place (E) or (S) in the blanks provided to indicate whether each of the following regulatory activities is an

example of an economic regulation or a social regulation:

___ a. Restraints on price-setting practices among firms

___ b. Clean air policy

___ c. Limits on the rates of return earned by utilities

___ d. Drug testing by the FDA

___ e. Requirement to provide electricity to every one who asks for it

___ f. Constraints on entry into and exit from given markets

2. Price controls are frequently mentioned as a possible means of controlling the potential abuses of

monopoly power. Pervasive use of price controls to limit monopoly power can, however, cause a plethora of

economic problems. In the blanks provided, check off those effects that might appear in a list of possible

difficulties existing with price controls:

___ a. Alienation of business and government

___ b. International trade problems

296

___ e. Shortages and surpluses

___ d. Absence of necessary flexibility in relative prices

___ e. Increased unemployment

3. Consult Figure 17-3.

Figure 17-3

a. For the indicated demand and cost curves, it is clear that the unregulated monopolist would produce

___ units of output for sale at a price of $___. Excess pure economic profits of $___ would then be

earned.

b. Regulation to the point of zero profits would meanwhile require a price specification of $___, at which

___ units of output would be expected. Consumer surplus would, in this case, increase from the

unregulated monopoly level of $18 to $___.

c. Ideal price regulation to the point where efficiency conditions were satisfied would, meanwhile, require

a price specification of $___, with ___ units of output expected only if the monopolist’s losses in the

amount of $___ were covered. Consumer surplus would rise further to $___ but would actually equal

$___ if the subsidy to cover the losses just noted were deducted. This (would / would not) represent an

improvement over the average-cost pricing alternative.

B. Antitrust Policy

4. a. Imperfect competition is undesirable from an economic standpoint mainly because of the (excess

profits generated by the exploitation of price and quantity / distortions that it produces in the

allocation of resources).

b. For a monopolist, the equality of marginal benefit and marginal cost does not result from self-

motivated profit maximization. Since price is always (greater than / equal to / less than) marginal

revenue, profit maximization requires that marginal cost be maintained at a level that is (higher than /

equal to / lower than) the going price. Why? Because profits are maximized where marginal cost equals

marginal revenue, and marginal revenue is less than price. Price ratios still reflect ratios of marginal

utility, though, so monopoly power yields marginal cost that is (higher than / equal to / lower than)

marginal benefit. Total welfare (cannot / can) then be improved by rearranging resources. How? In a way

which (brings resources into / moves resources out of) the monopolists’ markets to (increase / decrease)

their output. Based on the efficiency properties of the perfectly competitive market, it is clear that the

marginal utility derived from consuming the monopolist’s product is (greater than / less than / equal to)

the marginal cost of producing the good in question.

5. Consult Figure 17-4. The long-run competitive output and price for a market with the indicated cost

structure must equal __ units and $__, respectively. If this market is monopolized, an unregulated, profit-

maximizing monopolist would sell ___ units at a price of $___. The result would be a reduction in

297

consumer surplus from $___ to $___. Of that reduction, $___ would go to the monopolist in the form of

excess profit, and $___ would represent lost welfare that would disappear (deadweight loss).

Figure 17-4

6. a. Suppose that the monopolist depicted in Figure 17-4 faces a lump-sum tax on profits of $8. The

unregulated, profit-maximizing monopolist would then (increase the price above $8 / decrease the price

below $8 / maintain the price at $8) to support a (larger / smaller / constant) level of production and

sales.

b. Suppose, instead, that government taxes the monopolist’s implicit return to capital and that the

effective (constant) marginal cost of production thereby increases from $6 to $8 per unit. Output should

(fall to / rise to / continue to remain fixed at) ___ units; price would (climb to / fall to / remain at)

$___, representing an increase in price (equal to / less than / greater than) the $___ increase in unit

costs.

7. The text notes three important pieces of antitrust legislation that laid the groundwork for subsequent

antitrust activity:

1. The Sherman Antitrust Act (1890) (SA)

2. The Clayton Antitrust Act (1914) (CA)

3. The Federal Trade Commission Act (1914) (FTCA)

Match each of the following provisions to its landmark legislation by recording SA, CA, or FTCA in the

blanks provided; if none applies, write “none”:

___ a. Price discrimination that is not based upon cost differentials and is designed to lessen competition

is declared illegal.

___ b. Unfair and deceptive business activities and practices are declared illegal.

___ c. No corporation can acquire another if such an acquisition would substantially reduce competition.

___ d. Forming a monopoly is declared a felony.

___ e. Lobbying for tariff protection against foreign competition is declared illegal.

___ f. Restraint of trade or commerce among states is declared illegal.

___ g. Restraint of trade or commerce with foreign nations is declared illegal.

___ h. Imposing a contract which prohibits the purchase of a competitor’s product is illegal.

8. One significant change in the way that the legal system of the United States deals with the potential

problems of imperfect competition is found in the judicial attention paid to how business is actually conducted.

According to this new view of how the law should be enforced, it is more important to attack behavior that

signifies the abuse of market power than it is to concentrate on markets that display offensive industrial

organization. These abusive methods of conducting business, including (a) price fixing, (b) output restraint, (c)

market division, (d) predatory pricing, and (e) price discrimination, are not necessarily confined to the

concentrated industries with extreme and potentially profitable market power. Some of them can appear in

competitive markets as well.

The following list contains examples of the five types of conduct just noted. Identify each example with

the conduct that it represents, and record your answer in the space provided.

a. An agreement between retailers and the manufacturer not to sell a certain doll for less than $25:

298

b. The pricing of computers below production costs to prevent entry by potential competitors:

c. An agreement among suppliers of oil not to sell more than 1 million barrels per day:

d. A policy in which a particular firm sells hammers to hardware stores for $8.99 each and to the Defense

Department for $410.22 each:

e. An agreement among sugar retailers to sell only in specified geographical regions of the United States:

f. An agreement among airlines to increase fares 20 percent over the weekend:

g. The destruction of thousands of pounds of coffee beans before they get to market:

VIII. DISCUSSION QUESTIONS

Answer the following questions, making sure that you can explain the work you did to arrive at the answers.

1. Why might regulation using market incentives be more efficient than regulation using command-and-

control orders?

2. What major factors must be considered when deciding whether to regulate a monopolistic industry or break

it up? What basic criteria might you establish to help make this decision?

3. What are economies of scope? How do they differ from economies of scale?

4. Why might a regulator choose to impose marginal-cost pricing for a monopoly? List and explain two

different scenarios in which marginal-cost pricing might be appropriate. What will the effect be on the firm?

5. Review the three main pieces of antitrust legislation in the United States. What does each add to extend or

clarify the nature of antitrust policy?

6. Review the path of antitrust policy as it has been interpreted by the courts during this century.

7. Around the world today, many countries have different attitudes toward antitrust. In Japan, for example,

companies are encouraged to work together to gain a competitive edge over international competitors. The

government maintains a careful process of subsidization of industry that helps to germinate young businesses

and cushion the blows dealt by the business cycle. Given the nature of antitrust policy in the United States,

can our firms expect to compete in the global economy? Has the Sherman Antitrust Act outlived its

usefulness?

8. Do you think that the Bell doctrine, along with the recent decision against Microsoft, will discourage firms

from innovation?

VIII. Discussion Questions

1. Market incentives encourage firms to change their behavior as part of their own profit-maximizing strategy.

Command-and-control orders require firms to make decisions in order to avoid penalty. Thus, market

incentives may be more efficient.

2. Is the monopoly reasonable? Does the monopolist use unfair tactics to maintain monopoly power?

Criteria might include the difference between price and marginal cost, and the difference between price and

average costs. This would help us to determine how far the monopolist is from the competitive ideal.

3. Economies of scope exist when several products can be produced more efficiently by a single firm than by

separate firms. Economies of scale exist when a firm’s long-run average costs decline as output increases.

4. A regulator might choose marginal-cost pricing for a monopoly if it desires an outcome that mirrors the

competitive ideal. This holds prices low for customers. Marginal-cost pricing might be appropriate for a

public transportation company or for public housing. In both these cases, regulators want to keep prices for

consumers as low as possible. Firms would have to receive subsidies if they are to stay in business.

300

5. The three important pieces of legislation are the Sherman Antitrust Act, the Clayton Act, and the Federal

Trade Commission Act. Sherman is antimonopoly legislation, Clayton details illegal practices, and the FTC

Act established a regulatory agency to oversee antitrust activity.

6. Key points include swings between the rule of reason and per se illegality during this century, as well as

the existence of “merger mania” during the 1980s.

7. We may find that in order to compete internationally, U.S. firms must be allowed to work together in

some ways. However, this runs counter to the path of antitrust policy as it has been enforced over the past 100

years. The Sherman Act will have outlived its usefulness if we are willing to admit that decreased competition

among domestic producers is in the best interest of international competitiveness and consumer welfare.

8. Only time will tell. The returns to innovation are economic profits. Profitability is greater the longer the

firm can hang onto its monopoly power. If the FTC seems intent on prosecuting firms that are monopolies,

then the returns to innovation will fall!
