This project investigates the nexus of trade governance and regulatory standard-setting. More specically, the analysis focuses on the international legalization of Codex Alimentarius (Codex) and the International Organization for Standardization (ISO) through the World Trade Organization (WTO) in 1995. The project contributes to a small body of literature that argues that the international legalization of Codex and ISO through the WTO has led to a politicization of the two standard-setting organizations. Relying on social network analysis and two newly created datasets on the participation of state and non-state actors in the standard-setting processes at ISO and Codex, the principal objective of this project is to quantify the efect of international legalization on regulatory networks. This is important for two reasons: First, given the signicant role that international standards play in global trade and value chains, it is important to understand who actually develops them. Second, given the rise of regulatory networks, it is important to understand the consequences of inter-organizational collaboration and delegation.
