International Taxation Overview

Principles

Definition

International taxation is the academic field and area of legal and economic research focused on the tax implications of cross-border activities and the interaction of different national tax systems. It investigates how income, assets, and transactions spanning multiple countries are taxed, addressing issues such as the allocation of taxing rights between states, the prevention of double taxation, and the analysis of international tax planning, avoidance, and evasion strategies. Key characteristics include the study of bilateral tax treaties, domestic tax laws impacting international flows, transfer pricing principles, and the influence of international organizations and cooperation on global tax policy, underscoring its significance for facilitating international trade and investment, ensuring equitable taxation, and addressing challenges like base erosion and profit shifting in an interconnected global economy.

Key Figures

Modeling Tax Competition era

John D. Wilson [1], affiliated with Columbia University [3] and the University of Arkansas for Medical Sciences [4] during the 1980s, contributed to formal models of interregional tax competition. The 1986 paper A theory of interregional tax competition [7] introduced an analytical equilibrium framework that shows how mobile capital and jurisdictional sovereignty shape tax policy and the incentives for federal coordination in shaping open-economy outcomes. John Mutti [2], associated with the University of Wyoming [5] and Grinnell College [6] during this era, contributed to the literature on multinational decision making. His 1991 paper Taxes, Tariffs and Transfer Pricing in Multinational Corporate Decision Making [8] advanced understanding of how transfer pricing and cross-border taxation affect multinational behavior and provided empirical approaches aligned with endogeneity-aware analysis of jurisdictional policy in open economies.

Political-Economy Dynamics era

John D. Wilson [1] is associated with Indiana University Bloomington [3] and Michigan State University [4] during the Political-Economy Dynamics era. His contribution in this era centers on Theories of Tax Competition [7], which articulates how jurisdictional tax competition shapes policy choices and can drive race-to-the-bottom outcomes. Joel Slemrod [2] is affiliated with Massachusetts Institute of Technology [5] and Stanford University [6], and his scholarship in this era advanced understanding of tax evasion and compliance as central to international tax dynamics. Cheating Ourselves: The Economics of Tax Evasion [8] analyzes how tax evasion behavior affects policy design and enforcement, underscoring why compliance dynamics were crucial for understanding international tax competition in this period.

Information and Measurement era

Gabriel Zucman [1] is a prominent economist associated with University of California, Berkeley [3] and Princeton University [4] during the Information and Measurement era. The Missing Profits of Nations [6] is a key contribution from his work in this era, illustrating how data-driven measurement can quantify multinational profit shifting and inform enforcement-oriented policy. Ludvig Wier [2] is affiliated with University of California, Berkeley [3] and University of Copenhagen [5] during this era. As co-author of The Missing Profits of Nations [6], Ludvig Wier [2] contributes to the same measurement agenda, reinforcing the use of cross-border statistics to test the effectiveness of tax-avoidance controls in the Information and Measurement era.
