Read the following passage excerpt on fiscal federalism carefully:
"In analyzing the fiscal relations between central authorities and sub-national units, economists emphasize the delicate balance required when distributing unconditional block grants. While centralized revenue collection prevents inter-regional tax competition, it frequently creates a moral hazard where local administrations expand welfare liabilities without commensurate local taxation. To curb these profligate spending tendencies, federal oversight commissions usually introduce performance-indexed matching grants. However, policy analysts caution that when central oversight is applied too aggressively, it risks extinguishing sub-national fiscal autonomy altogether. A well-designed fiscal framework must therefore temper central regulatory intervention with statutory protections for regional policy discretion, ensuring that central fiscal discipline does not undermine the adaptive capacity of local governance."
