Public Finance Management in a Changing World: Dual Pressures from Demographic Transition and Pandemics

Abstract: This article examines the intersection of two critical forces shaping the future of public finance management (PFM): demographic change and pandemics. While demographic shifts—particularly population aging and declining fertility—exert gradual and structural pressures on fiscal sustainability, pandemics present sudden and disruptive shocks that demand immediate fiscal responses. Both phenomena challenge the ability of governments to maintain balanced budgets, deliver essential services, and preserve intergenerational equity. The article explores the revenue and expenditure implications of demographic trends, including the erosion of the tax base and increased obligations for pensions and healthcare. It also analyzes the fiscal mechanisms deployed during pandemics, such as emergency health spending, social protection expansion, and economic stimulus, while addressing the resulting strains on public debt and fiscal space. Through a comparative analysis, the article highlights key differences in temporal dynamics, policy design, and institutional requirements, while identifying synergies in resilient fiscal planning and modernized PFM systems. The study concludes that sustainable public finance systems must be both structurally adaptable to long-term demographic trends and operationally flexible to respond to crises. Recommendations include building fiscal buffers, reforming tax and pension systems, enhancing digital PFM infrastructure, and embedding equity and resilience into fiscal frameworks. By adopting integrated and forward-looking strategies, governments can better navigate the fiscal challenges posed by a rapidly aging world and recurring global health emergencies.
