How to Study Global Lawmaking: Lessons from Intellectual Property Rights and International Health Emergencies

International agreements on Intellectual Property (IP) have proven to be a good example to study global lawmaking. Beginning by looking at the 1990s Trade-Related Intellectual Property Rights (TRIPS) agreement and into the negotiation and implementation of regional and national trade agreements, this article reflects on the intricate relationship between international IP agreements and public health. The comprehensive analysis of these international rules and their effect provides valuable insights into the dynamic interplay between domestic and international factors in shaping health policies. Building upon the IP case, we categorize existing scholarship on global lawmaking into three methodological approaches: (a) methodological internationalism, (b) methodological nationalism, and (c) the interplay between domestic and international factors. We close with a call for researchers to advocate and integrate into their methods a co-constitutive approach that considers the simultaneous shaping of domestic and international elements.
