Jonathan Goupille-Lebret

Jonathan Goupille-Lebret serves as a CNRS Associate Professor in the Department of Economics at École normale supérieure de Lyon and conducts research at the Center for Economic Research on Governance, Inequality and Conflict (CERGIC). He maintains affiliate status with CEPR and CESifo networks in Public Economics while holding research fellow positions at the World Inequality Lab, EU Tax Observatory, and Institut des Politiques Publiques.

His empirical research focuses on tax policy and inequality dynamics, particularly through analysis of French wealth taxation systems and distributional national accounts. Key investigations examine how corporate markups, asset prices, and information availability influence tax elasticity and redistribution effectiveness. His methodology emphasizes large-scale administrative data and historical economic analysis to trace inequality patterns across decades.

Recent publications reveal growing emphasis on the interaction between pre-distribution mechanisms (labor market structures) and post-distribution policies (taxation/transfers), with particular attention to gender disparities in economic growth. His 2025 work extends this to markup-driven inequality and asset price effects on wealth concentration.

Goupille-Lebret actively contributes to collaborative research initiatives at the World Inequality Lab and EU Tax Observatory, where his team develops policy frameworks for progressive taxation. Through CERGIC and Institut des Politiques Publiques, he examines governance implications of rising inequality, connecting academic research to real-world fiscal policy design.
