Does decentralization matter for regional disparities? A cross-country analysis
利用26国1990-2006年面板数据，发现财政和政治分权对区域不平等的影响取决于发展水平、现有不平等程度和财政再分配能力；高收入国家分权降低不平等，中低收入国家财政分权加剧不平等。
This article looks at the relationship between fiscal and political decentralization and the evolution of regional inequalities in a panel of 26 countries-19 developed and 7 developing-for the period between 1990 and 2006. Using an instrumental variables method, it finds that whereas for the whole sample decentralization is completely dissociated from the evolution of regional disparities, the results are highly contingent on the level of development, the existing level of territorial inequalities, and the fiscal redistributive capacity of the countries in the sample. Decentralization in high income countries has, if anything, been linked with a reduction of regional inequality. In low and medium income countries, fiscal decentralization has been associated with a significant rise in regional disparities, which the positive effects of political decentralization have been unable to compensate. Policy preferences by subnational governments for expenditure in economic affairs, education, and social protection have contributed to this trend.
