Key Figures

Optimal Tax Design Theory era

Agnar Sandmo [1] held positions at University of Pennsylvania [3] and Norwegian School of Economics [4] during this era. Sandmo [1] contributed to the theory of income tax evasion with the paper Income tax evasion: a theoretical analysis [6], demonstrating how enforcement, audits, and penalties shape distortionary incentives and welfare. James A. Mirrlees [2] was based at University of Oxford [5] during this era. Mirrlees [2] authored An Exploration in the Theory of Optimum Income Taxation [7], which established foundational ideas for optimal income tax design and clarified how distortion costs and welfare considerations interact in tax policy.

Taxation and Corporate Incentives era

John D. Wilson [1] worked across Indiana University Bloomington [3] and Michigan State University [4] during this era. His key contribution, Theories of Tax Competition [7], formalized interjurisdictional tax competition and elucidated how marginal tax rates shaped location incentives and strategic choices for firms, a foundational insight for policy in this era. Jeffrey K. MacKie–Mason [2] was affiliated with University of California, Berkeley [5] and Berkeley College [6] in this period. Do Taxes Affect Corporate Financing Decisions? [8] analyzed how tax policy influences corporate financing decisions, revealing tax sensitivity of leverage and investment timing that helped explain corporate responses to reforms during 1990–2008.

Enforcement and Tax Governance era

Scott Dyreng [1] is a prominent scholar affiliated with Duke University [3] and the College of Accounting [4] during the Enforcement and Tax Governance era (2009-2024). His key contributions include The Effects of Executives on Corporate Tax Avoidance [7] and Using Financial Accounting Data to Examine the Effect of Foreign Operations Located in Tax Havens and Other Countries on U.S. Multinational Firms' Tax Rates [8], illustrating how executive incentives and cross-border operations shape tax avoidance under enforcement and disclosure regimes. Michelle Hanlon [2] is a leading scholar at Massachusetts Institute of Technology [5] and the University of Washington [6] during this era. Her contributions include co-authorship of The Effects of Executives on Corporate Tax Avoidance [7] and authorship of The taxman cometh: Does tax uncertainty affect corporate cash holdings? [9], underscoring how governance, information, and uncertainty reshape corporate tax behavior and capital management under enforcement regimes.
