Gabriel Zucman, born in 1986, is Professor of economics at the Paris School of Economics and Ecole normale supérieure – PSL, Summer Research Professor at the University of California, Berkeley, and founding Director of the EU Tax Observatory.

He is the author of articles published in journals such as the Quarterly Journal of Economics, the American Economic Review, the Review of Economic Studies, and of two books. His research focuses on the accumulation, distribution, and taxation of global wealth and has renewed the analysis of the macroeconomic and distributional implications of globalization.

In a series of papers and in his book The Hidden Wealth of Nations, he has developed methods to measure the wealth held in tax havens. This research finds that about 8% of the world’s household financial wealth is held in tax havens, with large variation across countries—from a few percent in Scandinavia to 50% in Russia. Data leaked from offshore financial institutions (such as the Panama Papers) suggest that offshore wealth is highly concentrated and frequently evades taxation absent cross-border information exchange.

A second strand of research combines theory and empirics to quantify the redistributive effects of international tax competition. The results suggest that close to 40% of multinational corporate profits are shifted to tax havens globally and more than 50% for US multinationals. This profit shifting has redistributive implications across countries and social groups. Granular results of this research, available at MissingProfits.world, make it possible to assess alternative forms of taxation of multinational companies, such as minimum taxes and the use of apportionment formulas.

With the members of the World Inequality Lab, he has developed prototype distributional national accounts, statistics that decompose macroeconomic growth by social group annually and in real time. With Emmanuel Saez, he has constructed series on the distribution of US wealth and with Thomas Piketty he has studied inequality in China, Russia, and the accumulation of capital in rich countries back to 1700. The results are available on the World Inequality Database and on RealTimeInequality.org for the United States.

Another area of research analyzes the economic effects of wealth taxation on capital accumulation, international mobility, inequality, tax avoidance, and tax evasion in France, Denmark, other European countries, and the United States. These studies shed light on current debates about the desirability and practicality of taxing wealth and of imposing minimum taxes on ultra-high-net-worth individuals.

The Triumph of Injustice, written with Emmanuel Saez, presents an analysis of the progressivity of the US tax system taking into account all taxes at all levels of government since the creation of the income tax in 1913. The book, supplemented by an open-source tax reform simulator, proposes to reinvent progressive taxation around three pillars: a progressive wealth tax, a new way to tax multinational companies, and a national income tax. It was awarded the Hans Matthöfer Prize and the Colbert Prize.

Gabriel Zucman received his PhD in 2013 and taught at the London School of Economics before joining the Berkeley faculty in 2015, and the Paris School of Economics and Ecole normale supérieure in 2023. He is the founding director of the PSE Stone center on Global Wealth Dynamics.

He received the John Bates Clark medal of the American Economic Association in 2023. He was elected Fellow of the Econometric Society in 2024. In 2021 he was named an Andrew Carnegie Fellow. He was awarded the Bernacer Prize and a Sloan Research Fellowship in 2019, the Best Young French Economist Prize awarded by Le Monde and le Cercle des Economistes in 2018, and the Excellence Award in Global Economic Affairs from the Kiel Institute for the World Economy in 2017.
