This comprehensive review synthesizes theoretical frameworks and empirical evidence on FD, examining its core pillars (expenditure assignment, revenue autonomy, transfers, borrowing) and diverse impacts. While FD holds potential for improving service delivery, accountability, and economic efficiency, outcomes vary significantly. The paper analyzes FD's complex effects on economic growth, poverty, inequality, regional disparities, environmental governance, macroeconomic stability, crisis response (including COVID-19), corruption, party systems, and secession risks. It underscores that FD's success is highly context-dependent, requiring robust institutions, political coherence, and careful design tailored to a country's history, capacity, and objectives. No single model fits all contexts. Length: 64 pages Creation-Date: 2025-07 File-URL: https://icepp.gsu.edu/files/2025/07/paper2511v3.pdf File-Format: application/pdf Handle: RePEc:ays:ispwps:paper2511
