The aim of this edited volume is to bring back multilateralism in global governance research by going beyond the state-centric and formal models of multilateralism of the 1990s and deeper into the informal private agents and structures of global governance. The volume is situated within the third generation scholarly research tying together disparate efforts from various disciplines, such as International Relations, Public Administration, International Law and International Political Economy under the overarching theme of multilateralism approached from the three different angles: normative dimensions of global governance, issue-areas, such as migration and international trade, as well as the limits of multilateralism.
