Research Project

Is International Economic Law International or Economic (or Law)? This research project challenges conventional wisdom about the nature of the law of the world economic order, with a view to widening the ideational lens through which scholars and professionals perceive the legal and institutional dimensions of global economic governance. It contests beliefs that experts often take for granted in their interactions with systems of liberal international economic ordering, questioning the traditional connections between law, history, political economy, and economics. The overriding goal of this project is to encourage experts to transcend the limits of technocratic discourse, prioritizing the bargaining for surplus between interest groups and the political struggle over rents, over a focus on text, policy, and principles as the prevailing themes of legal analysis.
