The Sherman Antitrust Act, passed by the U.S. Congress in 1890, is a landmark federal statute designed to promote fair competition and prevent monopolies and anticompetitive practices in the marketplace. Named after its primary sponsor, Senator John Sherman of Ohio, the act aimed to address growing concerns about the concentration of economic power in the hands of a few large corporations, often referred to as "trusts," during the late 19th century.
The Sherman Antitrust Act consists of two main provisions:
- Section 1: This section prohibits agreements, contracts, or conspiracies that unreasonably restrain trade or commerce among the states or with foreign nations. The language used in the statute is intentionally broad, encompassing a wide range of anticompetitive conduct. Over time, courts have interpreted this provision to cover both horizontal restraints (agreements among competitors) and vertical restraints (agreements between businesses at different levels of the supply chain). Examples of illegal conduct under Section 1 include price-fixing, bid-rigging, and market allocation agreements.
- Section 2: This section targets monopolization and attempts to monopolize any part of trade or commerce among the states or with foreign nations. To establish a violation of Section 2, the government must typically prove two elements: (a) the possession of monopoly power in the relevant market, and (b) the willful acquisition or maintenance of that power through exclusionary or anticompetitive conduct. Mere possession of monopoly power is not illegal; it is the abuse of that power that constitutes a violation of the act.
Enforcement and interpretation of the Sherman Antitrust Act primarily falls under the jurisdiction of the U.S. Department of Justice (DOJ) and the Federal Trade Commission (FTC), as well as private parties who may bring lawsuits for antitrust violations. Over the years, the scope and application of the act have evolved through court decisions and the development of economic theories. The act has also been supplemented by other federal antitrust laws, such as the Clayton Antitrust Act of 1914 and the Federal Trade Commission Act of 1914, which further refine and expand upon the principles established by the Sherman Act.
The Sherman Antitrust Act remains a critical tool for preserving competition and preventing anticompetitive practices in the United States. It seeks to protect consumers by promoting a competitive marketplace, which encourages innovation, drives down prices, and ensures a wide variety of goods and services.
