The Offshore Talks – Une exploration de l’évitement fiscal, de la fraude fiscale et des flux financiers illicites

Séminaires antérieurs :

🎥  Offshore: Stealth Wealth and the New Colonialism avec Brooke Harrington, professeur de sociologie économique, Dartmouth College.

🎥  Crack-Up Capitalism: Market Radicals and the Dream of a World Without Democracy avec Quinn Slobodian, professeur d’histoire internationale à la Frederick S. Pardee School of Global Studies de l’université de Boston.

The Golden Passport: Global Mobility for Millionaires avec Kristin Surak, professeur associé de sociologie politique à la London 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.
