The Institutional Model of Decentralization (IMD) is elaborated and used to explain two things: first, how the hypothesized improvements in efficiency and growth after decentralization may fail to materialize; second, how the interplay among economic, administrative and institutional factors affect the welfare outcome of decentralization, given the widespread local capture following political decentralization. Rather than exerting direct effects, however, the mechanism is complex, involving intangibles and feedback effects. When applied to actual cases in some regions, a particular method capable of capturing complex inter-relations and quantifying intangibles is therefore used. It is revealed that people's participation plays the most critical role in reducing capture while simultaneously maximizing welfare. As the quality of local leaders is found to be decisive in influencing the outcome, a typology of leaders is subsequently constructed.

IntroductionDecentralization is a multi-dimensional phenomenon, encompassing several interconnected aspects. Its theoretical supports originate in the informational advantage and coordination (policy enforcement) capability of local government. Although informational advantage can be secured by adopting a pro-market policy, a market system alone may not be sufficient to establish an effective coordination at the local level unless the decision making is decentralized. A more decentralized system, particularly on fiscal front, is also superior for promoting economic growth (United Nations 1991, Oates 1994, Bruno and Pleskovic 1996 No wonder the World Bank embraced decentralization as one of the major governance reforms on its agenda (World Bank 2000, Burki-PerryDillinger1999).Yet, the experience in many countries shows that the performance after decentralization has not always been consistent with the promise. Growth can be lower, and overall welfare conditions may not improve, if not worsen. Imperfections in local provision and poorly trained local bureaucrats are among the suggested reasons (Prud'homme 1994, Tanzi a Asian Development Bank, E-mail: iazis@adb.org ; and Cornell University 213 West Sibley Hall Ithaca, NY 14853, USA, E-mail: ija1@cornell.edu 1 Other justifications for decentralization include: raising efficiency through reduced transaction costs, diffusing social and political tensions, strengthening people's participation, and ensuring political and cultural autonomy.
