Market definition

Contents

Place in the Framework

Market definition frames the inquiry into monopoly power by identifying the product and geographic market in which competitive constraints operate.

Core Questions

  • What products or services are reasonable substitutes?
  • What geographic area reflects meaningful competitive constraints?
  • Can direct evidence of market power reduce the need for detailed market definition?
