Fiscal Devolution and Regional Equity in India: A Quantitative Assessment of Finance Commission Performance

This study provides empirical evidence that India's fiscal devolution mechanism, despite achieving unprecedented vertical resource transfers, has fundamentally failed to reduce regional disparities. Analyzing four Finance Commission cycles (2005-2026) through a novel Fiscal Stress Index and rigorous descriptive analysis, we document a critical paradox: while the 14th Finance Commission's historic increase in states' share from 32% to 42% enhanced fiscal autonomy, the coefficient of regional variation stubbornly persisted at 0.60-0.65, demonstrating that transfers alone cannot bridge structural development gaps. The Bihar case exemplifies this failure—receiving 43% above-average per capita transfers yet exhibiting the nation's worst development indicators, revealing absorptive capacity constraints that render additional resources ineffective. Furthermore, systematic erosion through cesses and surcharges reduced effective devolution from 42% to 33.4%, undermining constitutional principles. Our analysis reveals that 40% of India's population resides in crisis states (FSI > 6.0) trapped in self-reinforcing cycles of low revenue generation, high transfer dependence, and poor development outcomes. Statistical validation confirms fiscal stress explains over 50% of variance in development indicators across education, health, and economic dimensions. Critically, while relative disparities remained stable, absolute income gaps widened dramatically—the Maharashtra-Bihar gap increased 150% (₹79,000 to ₹198,000) between 2011-2022, undermining equity objectives. International comparison with Germany and Brazil demonstrates that institutional design trumps transfer quantum; successful federations achieve superior equity through conditional transfers, systematic capacity building, and performance accountability—mechanisms absent in India's framework. These findings necessitate transformational reform toward performance-based, conditional fiscal federalism. Recommendations include restructuring devolution formulas to reduce income distance weight from 45% to 30% while introducing 25% performance-based allocation, restoring constitutional devolution by bringing cesses under the divisible pool, and establishing crisis intervention protocols for high-stress states. Without such reforms, persistent disparities threaten national integration and federal democratic governance.
