Regulatory Influence and the International Diffusion of Pesticide Standards

Abstract This paper provides new empirical evidence on the international diffusion of sanitary standards, focusing on pesticide Maximum Residue Limits (MRLs) in the agri-food sector. We construct a novel dataset combining detailed information on national MRL regulations with bilateral trade flows and develop a measure of regulatory distance across countries. We show that countries trading more intensively tend to exhibit more similar regulatory standards, providing evidence of trade-driven regulatory convergence. This relationship is consistent with mechanisms of regulatory diffusion driven by market access and trade linkages. Citation Disdier, A.-C., Emlinger, C., & Kollegger-Steger, R. (2026).
