Professor
Isabelle Mejean serves as Professor in the Department of Economics at Sciences Po, specializing in international macroeconomics and international trade. Her prior academic appointments include Ecole Polytechnique, CEPII (Centre d'Etudes Prospectives et d'Informations Internationales), and the IMF Research Department. Education: PhD in Economics, University of Paris 1-Panthéon-Sorbonne (2006) Mejean's research explores micro-foundations of global trade systems, emphasizing firm-level adaptations to geopolitical shifts, environmental regulations, and supply chain disruptions. Her work bridges macroeconomic phenomena with granular trade data, investigating how carbon taxes reshape supply networks, how trade fragmentation affects economic security, and how labor market structures influence volatility resilience. This approach reveals critical mechanisms behind inflation transmission and policy spillovers across borders. Analysis of her 2022-2025 publications shows consistent focus on empirical trade dynamics using French manufacturing datasets and global firm networks. Key trends include quantifying carbon leakage through supply chains, mapping shock propagation in firm-to-firm trade, and evaluating de-risking strategies amid geopolitical tensions. Her research directly informs contemporary debates on climate-trade policy coherence and energy security. Scientific Awards: No awards documented in source material.
