Regime Complexes and European Studies in Interdisciplinary Perspective (EUROCOMPLEX) aims to foster interdisciplinary collaboration on the topic of regime complexes. Regime complex means that many policy areas are governed not by one overarching International Organization (IO) but rather by overlapping sets of rules and institutions that are loosely connected. The extension of policy competences to the European Union (EU) in the 1990 has led to the superposition of different regulatory and procedural regimes. The central question for the EUROCOMPLEX project is how the existence of regime complexes has impacted the policy options available to the EU as it tackles pressing international challenges created by economic globalization. EUROCOMPLEX provides a framework for collaborative research projects bringing together Princeton and University of Geneva faculty as well as undergraduate and graduate students from the European Union Program at Princeton (EUPP), the Global Studies Institute (GSI), and affiliated departments and programs, to study the constraints and opportunities offered to the EU by the proliferation of regime complexes. The project mixes students and senior researchers to investigate the impact of regime complexes in three specific policy areas: 1) the politics of foreign direct investment; 2) the taxation of multinational companies; and 3) the EU role in global governance. Each cluster is organized as a summer “lab” headed by one senior researcher and including students from each institution. Each lab carries out collaborative research in an interdisciplinary perspective blending notably Political Science and Law.   Participants Prof. Nicolas Levrat Ph.D. University of Geneva, Global Studies Institute Dr. Sophie Meunier Princeton University, Woodrow Wilson School of Public and International Affairs at Princeton University Dr. Didier Wernli University of Geneva, Global Studies Institute Yuliya Kaspiarovich University of Geneva, Global Studies Institute Grégoire Carasso University of Geneva, Global Studies Institute
