Sammendrag	IGO network analysis treats the web of states' memberships in intergovernmental organizations as a network and studies its structure and consequences. Using membership data such as the Correlates of War IGO dataset (Pevehouse, Nordstrom, and Warnke 2004), it represents which states belong to which organizations as an affiliation network, projects it into a state-to-state graph of shared memberships, and analyzes how organizational ties bind states together — measuring integration into global governance, detecting institutional blocs, and testing whether shared IGO membership shapes outcomes like trade and conflict.	Trade network analysis studies international trade as a weighted, directed graph in which states are nodes and trade flows are edges, then characterizes its structure and models how ties form. It moves beyond the standard dyadic gravity model by treating trade relationships as interdependent — a state's trade with one partner depends on the wider web of trade — and uses network science and inferential models such as latent space models (Ward, Ahlquist, and Rozenas 2013) to capture this dependence, identify hubs and blocs, and explain the architecture of the world trade system.
