Do U.S. Presidents Shape Tax Policy More Than Congress? New Research from Brandon Parsons Explores

Pepperdine Graziadio Business School faculty member Brandon Parsons has co-authored a new open-access study published in Public Choice, offering fresh insight into how U.S. presidents shape tax policy beyond legislation.

The research examines more than 100 years of tax data to explore the often-overlooked influence of the executive branch. The study finds that while statutory tax rates and congressional action typically dominate public attention, presidential administrations play a significant role in shaping the effective tax system through interpretation, enforcement, and administrative priorities.

The research highlights how presidents leverage institutional authority through agencies such as the U.S. Treasury and the Internal Revenue Service, influencing how tax laws are applied in practice. These executive actions can meaningfully impact tax outcomes, even in the absence of new legislation, particularly during periods of political gridlock.

By analyzing long-term trends, the study demonstrates that presidential leadership can leave distinct "fiscal fingerprints" on the tax system, affecting enforcement climates, shaping taxpayer behavior, and influencing overall tax burdens. The findings contribute to a broader understanding of how policy is implemented and underscore the expanding role of the executive branch in economic governance.
