Dr Paulsen draws upon rigorous archival research to afford a historical context to contemporary concerns. She is completing a book (with Oxford University Press) that will reconceptualise normative debates concerning the functions and limits of the most-favoured-nation principle for multilateral trade governance during the interwar period. Her forthcoming article in the Yale Journal of International Law (2025) reconstructs U.S. planning for multilateral institutions designed to secure the global economy, with two case studies from 1947 to 1953 to demonstrate how U.S. trade policy never separated economics and security. Her 2020 article, Trade Multilateralism and U.S. National Security: The Making of the GATT Security Exceptions, has been cited by a WTO dispute settlement panel report for the dispute US — Origin Marking (Hong Kong, China).
