Biography

Michael F. Motala, JD, PhD, is an assistant professor of Law and Political Science at the University of Tulsa College of Law who teaches advanced contracts, securities, taxation, and corporate law, he is an Instructor teaching Federal Income Taxation at Osgoode Hall Law School, York University's Professional Development Program, and serves as the Director, Taxation for the G20 Research Group and the G7 Research Group at the University of Toronto’s Munk School of Global Affairs. Michael’s primary expertise is in the global governance of international corporate taxation and its intersection with international economic law, and he has taught, conducted advanced research, and studied in the United States, Canada, the United Kingdom, Switzerland and France.

“This book is an outstanding study of how the remarkable 2021 agreement on the global corporate tax was reached and signed by over 140 countries. It should be read by anyone who is interested in the possibility of reaching multilateral solutions to global problems, not just tax experts.”

- Reuven S. Avi-Yonah, Irwin I. Cohn Professor of Law at the University of Michigan

“Motala’s book demonstrates how systemic shocks, expert networks anchored in the OECD, and distributional conflicts among States combined to alter the foundations of international corporate taxation. The analysis advances a ‘dynamic’ model of global corporate tax governance that explains both the evolutionary adjustments of the past decade and the potentially revolutionary character of the 2021 agreement. This model provides a coherent account of how crises trigger delegation to technical experts, how transnational epistemic communities construct new norms, and how bargaining among major powers and domestic political constraints determine the scope of implementation. This monograph stands out for offering not merely a historical record but an explanatory framework that will inform future scholarship on international economic law and multilateral governance.” 

-Julien Chaisse, Professor & RGC Senior Research Fellow, School of Law, City University of Hong Kong

“The 2021 Agreement on Global Corporate Tax was unambiguously a milestone in the ongoing fight against tax havens and all ensuing negative external effects. The author has managed to put together an authoritative account of the workings of this remarkable achievement, the process that led to it, and its consequences. It is a must read volume for academics and practitioners alike.”
