Massive Institutional Structures in Global Governance

Global governance consists of elementary regimes that form regime complexes, which in turn give rise to what we call superclusters around broad policy domains. In recent years, scholars have explored what these macroscopic structures look like and how they evolve over time. Yet the complex ways in which entire governance superclusters interact and coevolve, and what might emerge through this process, have not received much attention. In this article, we expand the ontological frontier of global governance research by offering a first bird’s-eye view on supercluster-level institutional interaction with an empirical focus on trade and environment. We constructed and analyzed a dynamic network-of-networks model, revealing a
