Antitrust Law: Competition Policy

Antitrust law promotes competition by prohibiting agreements and conduct that unreasonably restrict trade. These laws protect consumers from monopolistic practices and ensure market efficiency.

Sherman Act

The Sherman Act prohibits contracts, combinations, and conspiracies in restraint of trade. Section One addresses horizontal and vertical agreements. Section Two addresses monopolization and attempts to monopolize.

Rule of reason analysis examines agreements' actual competitive effects. Per se rules condemn certain arrangements without detailed analysis, including price-fixing, group boycotts, and market allocation.

Clayton Act

The Clayton Act addresses anticompetitive conduct not covered by the Sherman Act. Section Seven prohibits mergers and acquisitions that may substantially lessen competition. Section Two prohibits price discrimination. Section Three addresses tying and exclusive dealing.

Hart-Scott-Rodino requires pre-merger notification for large transactions. Regulatory agencies review proposed mergers to prevent harmful consolidation.

Enforcement

The FTC and Department of Justice enforce federal antitrust laws. State attorneys general pursue antitrust actions on behalf of consumers. Private parties may sue for injunctive relief and treble damages.
