Key Research Areas in Public Economics Students Can Explore

Public economics is a broad and rich discipline. Before you settle on a specific topic, it helps to understand the major research areas available to you. These areas are grounded in established academic literature and current policy debates.

Fiscal Policy and Government Budgeting This area examines how governments raise revenue and allocate public funds. Research in this space covers tax reform, deficit management, and the macroeconomic effects of fiscal decisions.

Taxation and Tax Policy Taxation remains one of the most active areas of public economics research. Topics range from the behavioural effects of income tax to the economics of carbon taxes and digital taxation.

Public Expenditure and Welfare Economics This area focuses on how public money is spent on education, health, housing, and social protection, and how effectively those funds achieve social outcomes.

Public Debt and Fiscal Sustainability With rising debt levels across many economies, there is growing academic interest in the long-term sustainability of government borrowing and its effects on growth and inequality.

Intergovernmental Fiscal Relations This covers how fiscal responsibilities are shared between central and local governments, including grants, fiscal decentralisation, and regional inequality.

Behavioural Public Economics This emerging area examines how psychological insights can improve the design of taxes, benefits, and public programmes.

Environmental and Climate Fiscal Policy Research here looks at how fiscal tools such as carbon pricing, green subsidies, and environmental taxes can support climate goals.
