Law Enforcement Under Incomplete Law: Theory and Evidence from Financial Market Regulation

Working Paper: CEPR ID: DP3788

Authors: Katharina Pistor; Chenggang Xu

Abstract: This Paper studies the design of law-making and law enforcement institutions based on the premise that law is inherently incomplete. Under incomplete law, law enforcement by courts may suffer from deterrence failure. As a potential remedy, a regulatory regime is introduced. The major functional difference between courts and regulators is that courts enforce law reactively, that is only once others have initiated law enforcement procedures, while regulators enforce law proactively, i.e. on their own initiative. We study optimal regime selection between a court and a regulatory regime and present evidence from the history of financial market regulation.
