Fiscal Policy and Economic Growth Dynamics
Summary
Fiscal policy, defined as government intervention through taxation and public expenditure, plays a pivotal role in shaping economic growth trajectories. It operates on dual objectives: stabilising cyclical fluctuations and enhancing long-run productive capacity. Empirical literature emphasises the composition of public spending—particularly investment in infrastructure, education and technology—as a fundamental determinant of potential output. In contrast, unproductive current expenditures and rising debt burdens have been linked to slower growth and heightened vulnerability to external shocks. Advances in econometric methods, including dynamic panel estimation and structural modelling, have improved our understanding of fiscal multipliers under varying macroeconomic conditions. Moreover, institutional quality and governance frameworks emerge as critical mediators of fiscal effectiveness, moderating the translation of budget outlays into sustainable growth. Global comparative studies reveal that optimal policy mixes are context-specific, requiring careful calibration of revenue measures, expenditure priorities and fiscal rules to balance efficiency, equity and intergenerational sustainability.
