Introduction
Over the last several decades, a revolution has been occurring in many countries around the globe, with the devolution of fiscal and political powers to subnational governments. This trend could be as influential for good governance and for improving the lives of ordinary citizens as major institutional transformations of the past century, such as decolonization in Africa and Asia or the transition from planned to market economies in the former Soviet Union and the People’s Republic of China (PRC).
Due to decentralization, many subnational governments have become key public sector actors. As such, their roles have grown, and expectations placed on them have increased. As countries continue to abandon centralized governance, it becomes increasingly important to know the impact of decentralization on a number of economic issues including growth and development; reducing poverty and achieving the Millennium Development Goals; advancing public services, such as education and health; and achieving greater macroeconomic stability with lower unemployment and inflation. The fundamental question is whether the ongoing decentralization trend is helping or hurting with these issues. The impact of devolution on a gamut of fundamental institutional issues, such as country unity versus separatism as well as the level of corruption, should also be scrutinized.
This policy note explores (i) why countries choose to decentralize their governance; (ii) what economic theory expects from decentralization; and (iii) what is known about the impact of decentralization on a relevant list of economic and political variables, as well as what conclusions are appropriate.
The Causes and Basic Theory of Decentralization
Countries begin decentralization processes for different reasons. Some are searching for a more efficient—and leaner—public sector, while others are disenchanted with the performance of planning and centralized policies (e.g., socialist economies). There are often grassroots demands to achieve democratic ideals. On the other hand, some movements are designed to contain or to appease centrifugal forces, ethnic conflicts, and/or separatism, and to diffuse social and political tensions by allowing local cultural and political autonomy. There may even be some political opportunism using decentralization for electoral objectives and/or just a desire to not be left behind in this popular form of institutional reform. While governments do not generally decentralize to pursue greater macro stability and economic growth, decentralization may impact upon these.
“Decentralization” generally means the devolution of decision-making powers. A related concept is “deconcentration,” in which operations are decentralized, but decision-making powers are not devolved. For example, many observers state that Bangladesh is a deconcentrated system, in which local governments are still subject to the control of central authorities, as opposed to a decentralized one, in which local governments have autonomy to set their own priorities and decide how best deliver public services. In addition, decentralization does not necessarily denote an erosion of central control nor of powers over issues and processes with national dimensions.1 Instead, it has political, administrative, and fiscal dimensions that are replicated more or less completely in different vertical spheres (i.e., regional and local).2
In recent years, there have been multiple extensions of the traditional theory of fiscal federalism (or the organization of intergovernmental fiscal relations) first developed by Oates in 1972. Viewing government as a benevolent agent, he created a decentralization theorem, which states that in the presence of diverse preferences and needs, provision of services from a decentralized government will lead to increased citizen welfare. This occurs because decentralized government leads to information advantages and more flexibility in adapting to citizens’ needs and preferences, as emphasized earlier by Hayek (1945). Today, the growing second-generation literature is based on the theory of “public choice,” assuming a political economy with selfish officials, as opposed to the benevolent agents in the previous literature. A branch of this literature, known as market-preserving federalism, focuses on incentives for government officials not to deviate from good behavior and emphasizes the role of decentralization as a mechanism to control an intrusive, expansive public sector and to support effective private markets (Weingast 1995, McKinnon 1997).
Classical federalism and the Tiebout hypothesis (addressing the competition among local governments and the mobility of individuals to find their preferred package of services) play major roles in the theory of local public finance.3 Unlike the case of pure Samuelson goods (in which the addition of individuals does not diminish the amount available to others and no one can be excluded from its consumption),
