Lucas Chancel is an economist. His work focuses on the study of economic inequality, its interactions with unsustainable development patterns, and on the implementation of social and ecological policies. His recent projects focused on the trends and determinants of income and wealth inequality (both past and present) in rich and developing countries as well as at the global level, based on the use of tax data, household surveys, national accounts and rich lists. He also seeks to better understand the trends and drivers of pollution inequalities within countries and between them.

He is also Co-Director of the World Inequality Lab at the Paris School of Economics (PSE), Senior Advisor at the European Tax Observatory.
