Evaluating The Long-Term Impact Of Fiscal And Monetary Policy Interventions On Economic Growth: A Comparative Analysis Of Emerging And Developed Economies

This paper examines the impact of long-term fiscal and monetary policy interventions on economic growth by comparing emerging and developed economies. Instead of generating new econometric estimates, the research synthesises empirical results from recent literature in macroeconomics to identify consistent patterns, deviations, and mechanisms underlying long-run growth outcomes. The results indicate that fiscal policy is more prominent in the emerging economies, where productive public expenditure and countercyclical interventions can be used to generate growth in the long term, especially with the assistance of the growing quality of institutions and fiscal governance. In the developed economies, there are further limits to the growth impact of fiscal policy, in terms of the sustainability of debt and dwindling returns, and the focal point is on efficiency and policy coordination. The long-term growth is supported by monetary policy mainly through price stability and anchoring inflation expectations. Plausible and autonomous central banks contribute to higher investment and productivity by decreasing macroeconomic uncertainty, and the greater and more predictable the effects are in developed economies. In both sets of countries, the institutional quality, the policy credibility, and the cooperation between the fiscal and monetary policies are the vital aspects of determining the performance in terms of long-run growth. The paper emphasises the relevance of context-based macroeconomic policies and offers policy-related suggestions on how to design sustainable growth-oriented interventions.
