Antitrust & Consumer Protection


ICLE’s antitrust and consumer protection research agenda emphasizes an empirical, evidence-based approach, informed by a decision theory (“error cost”) mode of analysis. Our scholars evaluate the social costs and benefits of proposed interventions, focusing in particular on how institutions affect the appropriateness and the effectiveness of antitrust enforcement.

Towards a Theory of Market Power

This paper analyzes the question of market power. Longstanding definitions and analytical tools are inadequate because they conflate conditions under which a firm has unbeneficial control over its markets (market power) with situations where firms are successful because they are superior in how they serve customers (expanding consumer welfare).
