Does decentralization … make it more difficult to adjust fiscal accounts once a structural deficit has developed? The experience of many countries suggests that under the circumstances often found in developing countries subnational governments are likely to contribute – sometimes significantly – to the aggravation of macroeconomic problems.

[C]ontrary to a common misconception, decentralized fiscal systems offer a greater potential for improved macroeconomic governance and regional fiscal equity than centralized fiscal systems. While empirical evidence on these questions is quite weak, nevertheless it further supports the conclusion that fiscal decentralization is associated with improved fiscal performance and better functioning of the internal common market. This is to be expected as decentralized fiscal systems require greater clarity in the roles of various players (centers of decision making), transparency in rules and greater care in the design of institutions that govern interactions to ensure fair play and limit opportunities for rent seeking.
