In today’s global economy, services make up a significant part of trade flows between countries. These include particularly dynamic sectors such as finance and the digital economy.

In this volume, renowned scholars and practitioners explain the rules of the GATS in detail, including a comprehensive and up-to-date analysis of WTO jurisprudence and scholarship.
