# Principles of Microeconomics/Regulating Anticompetitive Behavior

By the end of this section, you will be able to:
* Analyze restrictive practices
* Explain tying sales, bundling, and predatory pricing
* Evaluate a real-world situation of possible anticompetitive and restrictive practices
The U.S. antitrust laws reach beyond blocking mergers that would reduce competition to include a wide array of anticompetitive practices. For example, it is illegal for competitors to form a cartel to collude to make pricing and output decisions, as if they were a monopoly firm. The Federal Trade Commission and the U.S. Department of Justice prohibit firms from agreeing to fix prices or output, rigging bids, or sharing or dividing markets by allocating customers, suppliers, territories, or lines of commerce.
In the late 1990s, for example, the antitrust regulators prosecuted an international cartel of vitamin manufacturers, including the Swiss firm Hoffman-La Roche, the German firm BASF, and the French firm Rhone-Poulenc. These firms reached agreements on how much to produce, how much to charge, and which firm would sell to which customers. The high-priced vitamins were then bought by firms like General Mills, Kellogg, Purina-Mills, and Proctor and Gamble, which pushed up the prices more. Hoffman-La Roche pleaded guilty in May 1999 and agreed both to pay a fine of $500 million and to have at least one top executive serve four months of jail time.
Under U.S. antitrust laws, monopoly itself is not illegal. If a firm has a monopoly because of a newly patented invention, for example, the law explicitly allows a firm to earn higher-than-normal profits for a time as a reward for innovation. If a firm achieves a large share of the market by producing a better product at a lower price, such behavior is not prohibited by antitrust law.

# Restrictive Practices

Antitrust law includes rules against restrictive practices—practices that do not involve outright agreements to raise price or to reduce the quantity produced, but that might have the effect of reducing competition. Antitrust cases involving restrictive practices are often controversial, because they delve into specific contracts or agreements between firms that are allowed in some cases but not in others.
For example, if a product manufacturer is selling to a group of dealers who then sell to the general public it is illegal for the manufacturer to demand a minimum resale price maintenance agreement, which would require the dealers to sell for at least a certain minimum price. A minimum price contract is illegal because it would restrict competition among dealers. However, the manufacturer is legally allowed to “suggest” minimum prices and to stop selling to dealers who regularly undercut the suggested price. If you think this rule sounds like a fairly subtle distinction, you are right.
An exclusive dealing agreement between a manufacturer and a dealer can be legal or illegal. It is legal if the purpose of the contract is to encourage competition between dealers. For example, it is legal for the Ford Motor Company to sell its cars to only Ford dealers, for General Motors to sell to only GM dealers, and so on. However, exclusive deals may also limit competition. If one large retailer obtained the exclusive rights to be the sole distributor of televisions, computers, and audio equipment made by a number of companies, then this exclusive contract would have an anticompetitive effect on other retailers.
Tying sales happen when a customer is required to buy one product only if the customer also buys a second product. Tying sales are controversial because they force consumers to purchase a product that they may not actually want or need. Further, the additional, required products are not necessarily advantageous to the customer. Suppose that to purchase a popular DVD, the store required that you also purchase a portable TV of a certain model. These products are only loosely related, thus there is no reason to make the purchase of one contingent on the other. Even if a customer was interested in a portable TV, the tying to a particular model prevents the customer from having the option of selecting one from the numerous types available in the market. A related, but not identical, concept is called bundling, where two or more products are sold as one. Bundling typically offers an advantage for the consumer by allowing them to acquire multiple products or services for a better price. For example, several cable companies allow customers to buy products like cable, internet, and a phone line through a special price available through bundling. Customers are also welcome to purchase these products separately, but the price of bundling is usually more appealing.
In some cases, tying sales and bundling can be viewed as anticompetitive. However, in other cases they may be legal and even common. It is common for people to purchase season tickets to a sports team or a set of concerts so that they can be guaranteed tickets to the few contests or shows that are most popular and likely to sell out. Computer software manufacturers may often bundle together a number of different programs, even when the buyer wants only a few of the programs. Think about the software that is included in a new computer purchase, for example.
Recall from the chapter on [/contents/59781170-f68d-4de0-b434-96107a724c1e%408 Monopoly] that predatory pricing occurs when the existing firm (or firms) reacts to a new firm by dropping prices very low, until the new firm is driven out of the market, at which point the existing firm raises prices again. This pattern of pricing is aimed at deterring the entry of new firms into the market. But in practice, it can be hard to figure out when pricing should be considered predatory. Say that American Airlines is flying between two cities, and a new airline starts flying between the same two cities, at a lower price. If American Airlines cuts its price to match the new entrant, is this predatory pricing? Or is it just market competition at work? A commonly proposed rule is that if a firm is selling for less than its average variable cost—that is, at a price where it should be shutting down—then there is evidence for predatory pricing. But calculating in the real world what costs are variable and what costs are fixed is often not obvious, either.
The Microsoft antitrust case embodies many of these gray areas in restrictive practices, as the next Clear it Up shows.
Did Microsoft$^®$ engage in anticompetitive and restrictive practices?
The most famous restrictive practices case of recent years was a series of lawsuits by the U.S. government against Microsoft—lawsuits that were encouraged by some of Microsoft’s competitors. All sides admitted that Microsoft’s Windows program had a near-monopoly position in the market for the software used in general computer operating systems. All sides agreed that the software had many satisfied customers. All sides agreed that the capabilities of computer software that was compatible with Windows—both software produced by Microsoft and that produced by other companies—had expanded dramatically in the 1990s. Having a monopolyor a near-monopoly is not necessarily illegal in and of itself, but in cases where one company controls a great deal of the market, antitrust regulators look at any allegations of restrictive practices with special care.
The antitrust regulators argued that Microsoft had gone beyond profiting from its software innovations and its dominant position in the software market for operating systems, and had tried to use its market power in operating systems software to take over other parts of the software industry. For example, the government argued that Microsoft had engaged in an anticompetitive form of exclusive dealing by threatening computer makers that, if they did not leave another firm’s software off their machines (specifically, Netscape’s Internet browser), then Microsoft would not sell them its operating system software. Microsoft was accused by the government antitrust regulators of tying together its Windows operating system software, where it had a monopoly, with its Internet Explorer browser software, where it did not have a monopoly, and thus using this bundling as an anticompetitive tool. Microsoft was also accused of a form of predatory pricing; namely, giving away certain additional software products for free as part of Windows, as a way of driving out the competition from other makers of software.
In April 2000, a federal court held that Microsoft’s behavior had crossed the line into unfair competition, and recommended that the company be broken into two competing firms. However, that penalty was overturned on appeal, and in November 2002 Microsoft reached a settlement with the government that it would end its restrictive practices.
The concept of restrictive practices is continually evolving, as firms seek new ways to earn profits and government regulators define what is permissible and what is not. A situation where the law is evolving and changing is always somewhat troublesome, since laws are most useful and fair when firms know what they are in advance. In addition, since the law is open to interpretation, competitors who are losing out in the market can accuse successful firms of anticompetitive restrictive practices, and try to win through government regulation what they have failed to accomplish in the market. Officials at the Federal Trade Commission and the Department of Justice are, of course, aware of these issues, but there is no easy way to resolve them.

# Key Concepts and Summary

Firms are blocked by antitrust authorities from openly colluding to form a cartel that will reduce output and raise prices. Companies sometimes attempt to find other ways around these restrictions and, consequently, many antitrust cases involve restrictive practices that can reduce competition in certain circumstances, like tie-in sales, bundling, and predatory pricing.

# Self-Check Question

Why would a firm choose to use one or more of the anticompetitive practices described in [/contents/6f0e17ec-6ef1-4114-a112-c053ac7eaae6%407 Regulating Anticompetitive Behavior]?
Because outright collusion to raise profits is illegal and because existing regulations include gray areas which firms may be able to exploit.

# Review Questions

What is a minimum resale price maintenance agreement? How might it reduce competition and when might it be acceptable?
What is exclusive dealing? How might it reduce competition and when might it be acceptable?
What is a tie-in sale? How might it reduce competition and when might it be acceptable?
What is predatory pricing? How might it reduce competition, and why might it be difficult to tell when it should be illegal?

# Critical Thinking Questions

Can you think of any examples of successful predatory pricing in the real world?
If you were developing a product (like a web browser) for a market with significant barriers to entry, how would you try to get your product into the market successfully?
