Drawing on the analytical framework developed by Barbara Koremenos, Charles Lipson, and Duncan Snidal in the Rational Design project, I seek to shed light on the striking institutional differences among the various methods of international commercial dispute resolution for private parties. These methods include recourse to public courts and more frequently to private international courts, such as the International Court of Arbitration of the International Chamber of Commerce or the London Court of International Arbitration, as wen as recourse to so-called ad hoc arbitration and alternative dispute-resolution techniques, such as conciliation and mediation. The key institutional dimensions along which these methods of international dispute resolution vary are (1) procedural and adaptive flexibility, and (2) centralization of procedural safeguards and information collection. I explain why different methods of international commercial dispute resolution are selected. I argue that these methods respond to the varying institutional needs of different types of disputes and disputants. Such needs can be explained in terms of the severity of the enforcement problem, uncertainty about the preferences or behavior of contractual partners, and uncertainty about the state of the world.
