Paris School of Economics


The increased global mobility of capital and labour poses a number of challenges to national tax systems: intricate global structures to hide personal wealth from the eyes of tax administrators and regulators, conflicts about the international allocation of taxing rights, a fast-evolving international tax policy landscape. The seminar focuses on the topic of taxation in the global economy and aims to bring together international junior and senior researchers working on international taxation, tax avoidance and evasion, tax competition, tax harmonization and related topics. Presentations can be polished papers or work in progress. The aim is to learn from each other and to discuss in a friendly atmosphere.

The seminar takes place at Paris School of Economics and via Zoom.

If you would like to book a private time slot to meet the speaker, please email Manon Francois (manon.francois@psemail.eu) specifying which session.

This project has received funding from the European Union (TAXUD/2022/DE/310).

Get ready to delve behind the scenes at The Offshore Talks – our new lecture series designed to spark interdisciplinary dialogue and collaboration on the intricate topics of tax avoidance, tax evasion, and illicit financial flows.

Offshore: Behind the Scenes of Tax Havens  

🗓️ 14 May 2024 │18:00-19:30 (CET) 

Language: French 

📍 Room R2 -21, Paris School of Economics, 48 Bd Jourdan, 75014 Paris   

The Offshore Talks lecture series kicks off with Renaud Van Ruymbeke, whose latest book “Offshore: Dans les coulisses édifiantes des paradis fiscaux” provides unique insights into the workings of the opaque world of tax havens and secrecy jurisdictions.

For nearly two decades, this legendary French investigative magistrate delved into numerous politico-financial cases involving multinational tax evasion, large-scale tax fraud, corruption at the highest levels of government, and the widespread influence of tax havens.

Investigative journalist Maxime Vaudano from Le Monde will also join the discussion, shedding light on topics such as the emergence of new tax havens, frozen Russian assets, the contentious role of offshore banks amid the evolving international tax environment, and the shortcomings of automatic exchange of information agreements (CRS/FATCA). Vaudano’s career has been dedicated, among others, to unravelling the issues of tax evasion, financial crimes, and political-financial affairs, notably through his groundbreaking work on the Panama Papers, Paradise Papers, and OpenLux investigations.
