This book draws on experiences in developing countries to bridge the gap between the conventional textbook treatment of fiscal decentralization and the actual practice of subnational government finance. The extensive literature about the theory and practice is surveyed and longstanding problems and new questions are addressed. It focuses on the key choices that must be made in decentralizing, on how economic and political factors shape the choices that countries make, and on how, by paying more attention to the need for a more comprehensive approach and the critical connections between different components of decentralization reform, everyone involved might get more for their money.

This paper explores the impact of fiscal decentralization on the efficiency of public service delivery. It uses a stochastic frontier method to estimate time-varying efficiency coefficients and analyzes the impact of fiscal decentralization on those efficiency coefficients. The findings indicate that fiscal decentralization can improve the efficiency of public service delivery but only under specific conditions. First, the decentralization process requires adequate political and institutional environments. Second, a sufficient degree of expenditure decentralization seems necessary to obtain favorable outcomes. Third, decentralization of expenditure needs to be accompanied by sufficient decentralization of revenue. Absent those conditions, fiscal decentralization can worsen the efficiency of public service delivery.

Demand for decentralization is strong in most parts of the world. This close look at the negative side effects of improperly appled decentralization is not an attack on decentralization but an effort to prevent its misapplication -- and to promote fuller understanding and wiser use of this potentially desirable policy.

Reviews recent lessons about decentralized governance and implications for future development programs and policies.

Dissatisfied with centralized approaches to delivering local public services, a large number of countries are decentralizing responsibility for these services to lower-level, locally elected governments. The results have been mixed. The paper provides a framework for evaluating the benefits and costs, in terms of service delivery, of different approaches to decentralization, based on relationships of accountability between different actors in the delivery chain. Moving from a model of central provision to that of decentralization to local governments introduces a new relationship of accountability-between national and local policymakers-while altering existing relationships, such as that between citizens and elected politicians. Only by examining how these relationships change can we understand why decentralization can, and sometimes cannot, lead to better service delivery. In particular, the various instruments of decentralization-fiscal, administrative, regulatory, market, and financial-can affect the incentives facing service providers, even though they relate only to local policymakers. Likewise, and perhaps more significantly, the incentives facing local and national politicians can have a profound effect on the provision of local services. Finally, the process of implementing decentralization can be as important as the design of the system in influencing service delivery outcomes.

This text helps Latin American policymakers meet the challenge of decentralization to improve public sector performance at all levels of government by appropriately assigning jurisdiction over public goods, services, tax authority and user charges.
