The question of market definition for monopolization cases and thus the issue of the possession of market power by the defendant is crucial for the outcome of these cases. However, unlike antitrust merger analysis, where the DOJ-FTC Horizontal Merger Guidelines has provided a successful paradigm for market definition, monopolization cases lack a guiding market definition paradigm. This chapter addresses this issue, shows the problems that arise when a market definition paradigm is absent, and offers some partial remedies. The best remedy, though, would be the development of a suitable market definition paradigm for these cases.
