In one sentence

Antitrust (competition policy) uses laws and enforcement to prevent conduct or mergers that harm competition and consumers.

What antitrust targets

Common categories:

  • Cartels: price fixing, bid rigging, market allocation.
  • Exclusionary conduct by dominant firms: predatory pricing, refusal to deal, tying/bundling, exclusive dealing (jurisdiction-specific rules).
  • Mergers that substantially lessen competition.

Enforcement and tools

Typical tools include investigations, fines, behavioral remedies, structural remedies (divestitures), and merger review.

Comparative Analysis

In the United States, antitrust policy is characterized by a stringent legal framework and active enforcement primarily by the Department of Justice’s Antitrust Division and the Federal Trade Commission. This can be contrasted with the UK’s approach, where the Competition and Markets Authority (CMA) evaluates monopolies and mergers on a discretionary basis, focusing on overall market harm rather than absolute legal thresholds.

Case Studies

  • United States vs. Microsoft Corporation (1998): This landmark case addressed Microsoft’s monopolistic practices in the software industry, leading to a significant antitrust settlement.
  • AT&T Monopoly (1982): This historic breakup of the AT&T Corporation, which led to the creation of multiple smaller regional companies, demonstrated the application of antitrust policies to alleviate monopoly in telecommunications.
