Behavioral remedy

A behavioral remedy is an antitrust or regulatory intervention that constrains a firm's conduct without altering its corporate structure. Unlike structural remedies — which divide a firm into independent entities — behavioral remedies attempt to police the behavior of integrated firms through rules: nondiscrimination requirements, transparency mandates, pricing regulations, and interoperability obligations.

Behavioral remedies are the preferred instrument of the consumer welfare framework because they preserve the supposed efficiencies of integration while addressing its harms. The argument is that breaking up a firm destroys coordination benefits, unified investment, and economies of scope, and that conduct regulation can achieve competitive outcomes at lower cost. But this argument assumes that conduct can be effectively policed — an assumption that the history of antitrust enforcement repeatedly falsifies.

The problem with behavioral remedies is not merely enforcement difficulty. It is that integrated firms possess structural advantages — data access, cross-subsidization capabilities, preferential interconnection — that make evasion inevitable. A platform that both operates a marketplace and competes on it cannot be made neutral by rule, because the conflict of interest is encoded in its architecture. The essential facilities doctrine is a behavioral remedy that requires monopolists to grant access to competitors, but it does not eliminate the monopolist's incentive to degrade that access through technical means, pricing structures, or preferential treatment of its own services.

Behavioral remedies are therefore most appropriate in markets where integration produces genuine efficiencies and where the risks of structural separation exceed its benefits. But in markets with network effects, economies of scale, and infrastructural lock-in — telecommunications, digital platforms, financial clearing — behavioral remedies are systematically inadequate. The architecture of power cannot be regulated out of existence.

Behavioral remedies are the regulator's fantasy: the belief that a firm designed to extract rent can be taught to share it. The firm will comply with the letter of the rule while evading its spirit, because its structure — not its will — determines its behavior.
