Journal of Management and Business Solutions 3092-7226 In Press 2027 11 01 Political Fragmentation, Oil Revenue Volatility, and Fiscal Instability: A Dynamic Panel Analysis of Resource-Dependent Economies with Evidence from Iraq Political Fragmentation, Oil Revenue Volatility, and Fiscal Instability: A Dynamic Panel Analysis of Resource-Dependent Economies with Evidence from Iraq 1 23 EN Journal Article 2026 05 27 <p><a href="https://journalmbs.com/index.php/jmbs/Resource-dependent economies are particularly exposed to fiscal instability due to the inherent volatility of oil revenues and the constraints imposed by fragmented political systems. This study investigates the dynamic relationship between political fragmentation, institutional quality, oil revenue volatility, and fiscal performance in resource-rich economies, with a focused empirical illustration of Iraq. Using a panel dataset covering major oil-exporting countries and applying advanced econometric techniques such as System Generalized Method of Moments and vector autoregressive models, the study identifies the channels through which political and institutional factors shape fiscal behavior. The findings reveal that political fragmentation intensifies fiscal procyclicality by weakening budget coordination and increasing short-term political bargaining over public expenditures. Oil revenue volatility emerges as a central determinant of fiscal instability, contributing significantly to expenditure fluctuations, deficit cycles, and reduced fiscal predictability. Conversely, stronger institutional quality mitigates these adverse effects by improving fiscal discipline, enhancing budgetary planning, and stabilizing expenditure patterns. The case of Iraq further demonstrates how persistent political divisions and institutional weaknesses exacerbate the negative fiscal consequences of oil dependence, despite substantial hydrocarbon wealth. The study concludes that fiscal sustainability in resource-dependent economies requires institutional strengthening and the adoption of countercyclical fiscal frameworks that can insulate public finances from commodity price shocks and political distortions.">Resource-dependent economies are particularly exposed to fiscal instability due to the inherent volatility of oil revenues and the constraints imposed by fragmented political systems.
