Economic Analysis of Tax Policy

Vak
2026-2027

Admission requirements

Prospective students are recommended to have completed at least one year of university education (not necessarily in law or economics). Proficiency in English; both verbal and written; is expected.

Description

Context
Economics is the social science that studies choices and tradeoffs: households and firms only have limited resources (time, money), hence they cannot choose everything all at once. This course serves as an introduction to household and firm decision-making and the role taxes play in affecting agents’ behavior.

We study the challenges faced by governments in designing their tax systems in line with their policy goals while being constrained by individuals and businesses who intend to reduce their tax liability. Such strategic behavior by individuals has implications for economic activity in general and the income and wealth distribution in particular. We study these contributions from an economic perspective, including welfare economics. Rather than focusing on the details of a specific tax law, the course introduces key concepts that help understand the functions and effects of tax systems as a whole. Students can use these concepts to analyze current tax policy debates.

Place within the minor '(inter)national Tax Planning and Policy'
This course is part of the foundational track of the minor ‘(Inter)national tax planning and policy’. The minor investigates the nature and impact of tax planning activities by individuals and companies as well as the policy responses by governments; both in domestic law and through international cooperation. This course introduces students to the economic perspective by studying optimizing behavior of both citizens and businesses; and the strategic behavior of governments in response to this.

Design of the course
The course starts with an introduction of the key economic principles of tax incidence and the welfare loss of taxation. The course then applies these insights to various parts of the tax system. This includes the taxation of income and wealth, and the taxation of businesses. We discuss what tax design implies for income redistribution and what incentives exist for strategic interaction between governments. This includes international cooperation amongst governments on topics such as profit shifting and labor taxation.

Course objectives

Upon successful completion of the course, students know the basic insights underlying the economic analysis of tax systems and are able to apply this knowledge to a number of recent policy debates.
At the end of this course, students will be able to:

  • explain the basic principles of the economic analysis of tax systems;

  • describe how the economic perspective compares to the legal perspective;

  • explain how individuals and businesses behave in response to tax systems;

  • explain how governments design tax systems strategically and in cooperation with other governments;

  • interpret recent policy debates using the economic concepts discussed.
