In the United States, antitrust law is a collection of federal and state government laws that regulates the conduct and organization of business corporations, generally to promote competition for the benefit of consumers. The main statutes are the Sherman Act of 1890, the Clayton Act of 1914 and the Federal Trade Commission Act of 1914. These Acts serve three major functions. First, Section 1 of the Sherman Act prohibits price-fixing and the operation of cartels, and prohibits other collusive practices that unreasonably restrain trade. Second, Section 7 of the Clayton Act restricts the mergers and acquisitions of organizations that would likely substantially lessen competition. Third, Section 2 of the Sherman Act prohibits the abuse of monopoly power.
