Summary

Antitrust violations refer to breaches of laws designed to promote economic competition and prevent unjustified monopolies. In the United States, these are primarily governed by federal laws such as the Sherman Act of 1890, the Clayton Act of 1914, and the Federal Trade Commission Act of 1914, which prohibit practices like price fixing, cartels, monopolization, anti-competitive mergers, and price discrimination. Enforcement is carried out by federal agencies like the Federal Trade Commission and the U.S. Department of Justice's Antitrust Division, as well as private parties and state governments. The scope and impact of antitrust laws are subjects of ongoing debate, with economists generally agreeing on the need for vigorous enforcement and expressing concerns about concentrated corporate economic power. A recent significant development involves the European Union charging Microsoft with antitrust violations for bundling Microsoft Teams with its dominant Microsoft Office suite, a case initiated by a complaint from Salesforce, highlighting ongoing discussions about bundling's impact on innovation and fair market competition.

United States antitrust law

In the United States, antitrust law is a collection of mostly federal laws that govern the conduct and organization of businesses in order to promote economic competition and prevent unjustified monopolies. The three main U.S. antitrust statutes are the Sherman Act of 1890, the Clayton Act of 1914, and the Federal Trade Commission Act of 1914. Section 1 of the Sherman Act prohibits price fixing and the operation of cartels, and prohibits other collusive practices that unreasonably restrain trade. Section 2 of the Sherman Act prohibits monopolization. Section 7 of the Clayton Act restricts the mergers and acquisitions of organizations that may substantially lessen competition or tend to create a monopoly. The Robinson–Patman Act, an amendment to the Clayton Act, prohibits price discrimination. Federal antitrust laws provide for both civil and criminal enforcement. Civil antitrust enforcement occurs through lawsuits filed by the Federal Trade Commission (FTC), the Antitrust Division of the U.S. Department of Justice, and private parties who have been harmed by an antitrust violation. Criminal antitrust enforcement is done only by the Justice Department's Antitrust Division. Additionally, U.S. state governments may also enforce their own antitrust laws, which mostly mirror federal antitrust laws, regarding commerce occurring solely within their own state's borders. The scope of antitrust laws, and the degree to which they should interfere in an enterprise's freedom to conduct business, or to protect smaller businesses, communities and consumers, are strongly debated. Some economists argue that antitrust laws actually impede competition, and may discourage businesses from pursuing activities that would be beneficial to society. One view suggests that antitrust laws should focus solely on the benefits to consumers and overall efficiency, while a broad range of legal and economic theory sees the role of antitrust laws as also controlling economic power in the public interest. Surveys of American Economic Association (AEA) members since the 1970s have shown that professional economists generally agree with the statement: "Antitrust laws should be enforced vigorously." A 1990 survey of AEA members found that 72 percent generally agreed that "Collusive behavior is likely among large firms in the United States", while a 2021 survey found that 85 percent generally agreed that "Corporate economic power has become too concentrated."

    In the past several years, the FTC and DOJ, along with many state attorneys general, have filed five lawsuits against the four tech giants on different claims of antitrust violations (see sidebar).

The companies are fiercely defending themselves, arguing that they are not violating antitrust laws, that they invest in innovation that benefits consumers, and that they are not stifling competition. Amazon, for one, calls the antitrust lawsuit against it a “fundamental misunderstanding of retail” and warns that if the FTC wins, product prices may rise and its popular Prime shipping [...] After a long dry spell in antitrust prosecution — the last major case was against Microsoft in the late 1990s — the federal government is suing Apple, Amazon, Meta (Facebook’s parent company), and Google for allegedly constructing illegal monopolies that harm consumers and choke innovation.
