The Federal Trade Commission, established over 100 years ago, has two enforcement arms: a "competition" bureau that enforces antitrust laws, and a "consumer protection" bureau with authority to prohibit unfair and deceptive practices. Given that they have long been combined in a single dual-mission agency, one might expect these two competencies—antitrust and consumer protection—to be closely interrelated. But traditionally they have not been, and lawyers specializing in the two areas have largely occupied separate and distinct provinces.
