Symposium: the global minimum tax – introduction

In October 2021, 137 countries of the OECD's Inclusive Framework reached an historic agreement paving the way for the introduction of a global minimum tax (GMT) on the profits of large multinational companies (MNEs). The agreement was hyailed by Janet Yellen, Secretary of the US Treasury, as a "once-in-a-generation accomplishment for economic diplomacy." If the GMT is successfully implemented, then this claim would arguably be justified. The group of papers included in this symposium address some of the key issues arising in the design of the GMT.
