Free and open markets are the foundation of a vibrant economy. Aggressive competition among sellers in an open marketplace gives consumers — both individuals and businesses — the benefits of lower prices, higher quality products and services, more choices, and greater innovation. The FTC’s competition mission is to enforce the rules of the competitive marketplace — the antitrust laws. These laws promote vigorous competition and protect consumers from anticompetitive mergers and business practices. The FTC’s Bureau of Competition, working in tandem with the Bureau of Economics, enforces the antitrust laws for the benefit of consumers.

The Bureau of Competition has developed a variety of resources to help explain its work. For an overview of the types of matters investigated by the Bureau, read Competition Counts. This Guide to the Antitrust Laws contains a more in-depth discussion of competition issues for those with specific questions about the antitrust laws. From the table at the bottom, you will find Fact Sheets on a variety of competition topics, with examples of cases and Frequently Asked Questions. Within each topic you will find links to more detailed guidance materials developed by the FTC and the U.S. Department of Justice.

The Commission cannot represent individuals or businesses, and these resources are not intended to substitute for legal advice.

Congress passed the first antitrust law, the Sherman Act, in 1890 as a “comprehensive charter of economic liberty aimed at preserving free and unfettered competition as the rule of trade.” In 1914, Congress passed two additional antitrust laws: the Federal Trade Commission Act, which created the FTC, and the Clayton Act. With some revisions, these are the three core federal antitrust laws still in effect today.

The antitrust laws proscribe unlawful mergers and business practices in general terms, leaving courts to decide which ones are illegal based on the facts of each case. Courts have applied the antitrust laws to changing markets, from a time of horse and buggies to the present digital age. Yet for over 100 years, the antitrust laws have had the same basic objective: to protect the process of competition for the benefit of consumers, making sure there are strong incentives for businesses to operate efficiently, keep prices down, and keep quality up.

Here is an overview of the three core federal antitrust laws.

The Sherman Act outlaws “every contract, combination, or conspiracy in restraint of trade,” and any “monopolization, attempted monopolization, or conspiracy or combination to monopolize.” Long ago, the Supreme Court decided that the Sherman Act does not prohibit every restraint of trade, only those that are unreasonable. For instance, in some sense, an agreement between two individuals to form a partnership restrains trade, but may not do so unreasonably, and thus may be lawful under the antitrust laws. On the other hand, certain acts are considered so harmful to competition that they are almost always illegal. These include plain arrangements among competing individuals or businesses to fix prices, divide markets, or rig bids. These acts are “per se” violations of the Sherman Act; in other words, no defense or justification is allowed.

The penalties for violating the Sherman Act can be severe. Although most enforcement actions are civil, the Sherman Act is also a criminal law, and individuals and businesses that violate it may be prosecuted by the Department of Justice. Criminal prosecutions are typically limited to intentional and clear violations such as when competitors fix prices or rig bids. The Sherman Act imposes criminal penalties of up to $100 million for a corporation and $1 million for an individual, along with up to 10 years in prison. Under federal law, the maximum fine may be increased to twice the amount the conspirators gained from the illegal acts or twice the money lost by the victims of the crime, if either of those amounts is over $100 million.

The Federal Trade Commission Act bans “unfair methods of competition” and “unfair or deceptive acts or practices.” The Supreme Court has said that all violations of the Sherman Act also violate the FTC Act. Thus, although the FTC does not technically enforce the Sherman Act, it can bring cases under the FTC Act against the same kinds of activities that violate the Sherman Act. The FTC Act also reaches other practices that harm competition, but that may not fit neatly into categories of conduct formally prohibited by the Sherman Act. Only the FTC brings cases under the FTC Act.

The Clayton Act addresses specific practices that the Sherman Act does not clearly prohibit, such as mergers and interlocking directorates (that is, the same person making business decisions for competing companies). Section 7 of the Clayton Act prohibits mergers and acquisitions where the effect “may be substantially to lessen competition, or to tend to create a monopoly.” As amended by the Robinson-Patman Act of 1936, the Clayton Act also bans certain discriminatory prices, services, and allowances in dealings between merchants. The Clayton Act was amended again in 1976 by the Hart-Scott-Rodino Antitrust Improvements Act to require companies planning large mergers or acquisitions to notify the government of their plans in advance. The Clayton Act also authorizes private parties to sue for triple damages when they have been harmed by conduct that violates either the Sherman or Clayton Act and to obtain a court order prohibiting the anticompetitive practice in the future.

In addition to these federal statutes, most states have antitrust laws that are enforced by state attorneys general or private plaintiffs. Many of these statutes are based on the federal antitrust laws.

The Federal Government

Both the FTC and the U.S. Department of Justice (DOJ) Antitrust Division enforce the federal antitrust laws. In some respects their authorities overlap, but in practice the two agencies complement each other. Over the years, the agencies have developed expertise in particular industries or markets. For example, the FTC devotes most of its resources to certain segments of the economy, including those where consumer spending is high: health care, pharmaceuticals, professional services, food, energy, and certain high-tech industries like computer technology and Internet services. Before opening an investigation, the agencies consult with one another to avoid duplicating efforts. In this guide, “the agency” means either the FTC or DOJ, whichever is conducting the antitrust investigation.

Premerger notification filings, correspondence from consumers or businesses, Congressional inquiries, or articles on consumer or economic subjects may trigger an FTC investigation. Generally, FTC investigations are non-public to protect both the investigation and the individuals and companies involved. If the FTC believes that a person or company has violated the law or that a proposed merger may violate the law, the agency may attempt to obtain voluntary compliance by entering into a consent order with the company. A company that signs a consent order need not admit that it violated the law, but it must agree to stop the disputed practices outlined in an accompanying complaint or take certain steps to resolve the anticompetitive aspects of its proposed merger.

If a consent agreement cannot be reached, the FTC may issue an administrative complaint and/or seek injunctive relief in the federal courts. The FTC’s administrative complaints initiate a formal proceeding that is much like a federal court trial but before an administrative law judge: evidence is submitted, testimony is heard, and witnesses are examined and cross-examined. If a law violation is found, a cease and desist order may be issued. An initial decision by an administrative law judge may be appealed to the Commission.

Final decisions issued by the Commission may be appealed to a U.S. Court of Appeals and, ultimately, to the U.S. Supreme Court. If the Commission’s position is upheld, the FTC, in certain circumstances, may then seek consumer redress in court. If the company violates an FTC order, the Commission also may seek civil penalties or an injunction.

In some circumstances, the FTC can go directly to federal court to obtain an injunction, civil penalties, or consumer redress. For effective merger enforcement, the FTC may seek a preliminary injunction to block a proposed merger pending a full examination of the proposed transaction in an administrative proceeding. The injunction preserves the market’s competitive status quo.

The FTC also may refer evidence of criminal antitrust violations to the DOJ. Only the DOJ can obtain criminal sanctions. The DOJ also has sole antitrust jurisdiction in certain industries, such as telecommunications, banks, railroads, and airlines. Some mergers also require approval of other regulatory agencies using a “public interest” standard. The FTC or DOJ often work with these regulatory agencies to provide support for their competitive analysis.

States

State attorneys general can play an important role in antitrust enforcement on matters of particular concern to local businesses or consumers. They may bring federal antitrust suits on behalf of individuals residing within their states (“parens patriae” suits), or on behalf of the state as a purchaser. The state attorney general also may bring an action to enforce the state’s own antitrust laws. In merger investigations, a state attorney general may cooperate with federal authorities. For more information on joint federal-state investigations, consult the Protocol for Coordination in Merger Investigations.

Private Parties

Private parties can also bring suits to enforce the antitrust laws. In fact, most antitrust suits are brought by businesses and individuals seeking damages for violations of the Sherman or Clayton Act. Private parties can also seek court orders preventing anticompetitive conduct (injunctive relief) or bring suits under state antitrust laws. Individuals and businesses cannot sue under the FTC Act.

Issues of International Jurisdiction

U.S. and foreign competition authorities may cooperate in investigating cross-border conduct that has an impact on U.S. consumers. For more information on the application of U.S. antitrust laws to businesses with international operations, consult the Antitrust Guidelines For International Enforcement and Cooperation. In addition, as more U.S. companies and consumers do business overseas, federal antitrust work often involves cooperating with international authorities around the world to promote sound competition policy approaches. There are now more than 130 foreign competition agencies. For more information on the agency’s work with these authorities, visit the Office of International Affairs web pages.

In order to compete in modern markets, competitors sometimes need to collaborate. Competitive forces are driving firms toward complex collaborations to achieve goals such as expanding into foreign markets, funding expensive innovation efforts, and lowering production and other costs.

In today’s marketplace, competitors interact in many ways, through trade associations, professional groups, joint ventures, standard-setting organizations, and other industry groups. Such dealings often are not only competitively benign but procompetitive. But there are antitrust risks when competitors interact to such a degree that they are no longer acting independently, or when collaborating gives competitors the ability to wield market power together.

For the most blatant agreements not to compete, such as price fixing, big rigging, and market division, the rules are clear. The courts decided many years ago that these practices are so inherently harmful to consumers that they are always illegal, so-called per se violations. For other dealings among competitors, the rules are not as clear-cut and often require fact-intensive inquiry into the purpose and effect of the collaboration, including any business justifications. Enforcers must ask: what is the purpose and effect of dealings among competitors? Do they restrict competition or promote efficiency?

These Fact Sheets provide more detail about the types of dealings with competitors that may result in an antitrust investigation. For further guidance, read Antitrust Guidelines for Collaborations Among Competitors.

Price fixing is an agreement (written, verbal, or inferred from conduct) among competitors that raises, lowers, or stabilizes prices or competitive terms. Generally, the antitrust laws require that each company establish prices and other terms on its own, without agreeing with a competitor. When consumers make choices about what products and services to buy, they expect that the price has been determined freely on the basis of supply and demand, not by an agreement among competitors. When competitors agree to restrict competition, the result is often higher prices. Accordingly, price fixing is a major concern of government antitrust enforcement.

A plain agreement among competitors to fix prices is almost always illegal, whether prices are fixed at a minimum, maximum, or within some range. Illegal price fixing occurs whenever two or more competitors agree to take actions that have the effect of raising, lowering or stabilizing the price of any product or service without any legitimate justification. Price-fixing schemes are often worked out in secret and can be hard to uncover, but an agreement can be discovered from “circumstantial” evidence. For example, if direct competitors have a pattern of unexplained identical contract terms or price behavior together with other factors (such as the lack of legitimate business explanation), unlawful price fixing may be the reason. Invitations to coordinate prices also can raise concerns, as when one competitor announces publicly that it is willing to end a price war if its rival is willing to do the same, and the terms are so specific that competitors may view this as an offer to set prices jointly.

Not all price similarities, or price changes that occur at the same time, are the result of price fixing. On the contrary, they often result from normal market conditions. For example, prices of commodities such as wheat are often identical because the products are virtually identical, and the prices that farmers charge all rise and fall together without any agreement among them. If a drought causes the supply of wheat to decline, the price to all affected farmers will increase. An increase in consumer demand can also cause uniformly high prices for a product in limited supply.

Price fixing relates not only to prices, but also to other terms that affect prices to consumers, such as shipping fees, warranties, discount programs, or financing rates. Antitrust scrutiny may occur when competitors discuss the following topics:

• Present or future prices
• Pricing policies
• Promotions
• Bids
• Costs
• Capacity
• Terms or conditions of sale, including credit terms
• Discounts
• Identity of customers
• Allocation of customers or sales areas
• Production quotas
• R&D plans

A defendant is allowed to argue that there was no agreement, but if the government or a private party proves a plain price-fixing agreement, there is no defense to it. Defendants may not justify their behavior by arguing that the prices were reasonable to consumers, were necessary to avoid cut-throat competition, or stimulated competition.

Example: A group of competing optometrists agreed not to participate in a vision care network unless the network raised reimbursement rates for patients covered by its plan. The optometrists refused to treat patients covered by the network plan, and, eventually, the company raised reimbursement rates. The FTC said that the optometrists’ agreement was illegal price fixing, and that its leaders had organized an effort to make sure other optometrists knew about and complied with the agreement.

An agreement to restrict production, sales, or output is just as illegal as direct price fixing, because reducing the supply of a product or service drives up its price. For example, the FTC challenged an agreement among competing oil importers to restrict the supply of lubricants by refusing to import or sell those products in Puerto Rico. The competitors were seeking to pressure the legislature to repeal an environmental deposit fee on lubricants, and warned of lubricant shortages and higher prices. The FTC alleged that the conspiracy was an unlawful horizontal agreement to restrict output that was inherently likely to harm competition and that had no countervailing efficiencies that would benefit consumers.

Q: The gasoline stations in my area have increased their prices the same amount and at the same time. Is that price fixing?

A: A uniform, simultaneous price change could be the result of price fixing, but it could also be the result of independent business responses to the same market conditions. For example, if conditions in the international oil market cause an increase in the price of crude oil, this could lead to an increase in the wholesale price of gasoline. Local gasoline stations may respond to higher wholesale gasoline prices by increasing their prices to cover these higher costs. Other market forces, such as publicly posting current prices (as is common with most gasoline stations), encourages suppliers to adjust their own prices quickly in order not to lose sales. If there is evidence that the gasoline station operators talked to each other about increasing prices and agreed on a common pricing plan, however, that may be an antitrust violation.

Q: Our company monitors competitors’ ads, and we sometimes offer to match special discounts or sales incentives for consumers. Is this a problem?

A: No. Matching competitors’ pricing may be good business, and occurs often in highly competitive markets. Each company is free to set its own prices, and it may charge the same price as its competitors as long as the decision was not based on any agreement or coordination with a competitor.
