A Comprehensive Analysis of Expenditure Decentralization and of the Composition of Local Public Spending

S acchi A. and S alotti S. A comprehensive analysis of expenditure decentralization and of the composition of local public spending, Regional Studies . Many industrialized countries have recently implemented fiscal decentralization reforms assigning more spending responsibility to sub-national governments. This paper investigates the causes of the decentralization of different categories of public expenditure in 19 developed countries over the period 1980-2006. Different models for each of the spending functions under analysis are estimated adopting a general-to-specific empirical approach. Results confirm existing findings on the negative link between regional income disparities and expenditure decentralization. A similarly negative relationship is found for a set of demographic variables, leading to the conclusion that macroeconomic and, more importantly, political factors are responsible for the recent increase in decentralization. Finally, the analysis is completed by a study of the factors driving sub-national expenditure composition, with political and demographic changes emerging as the most important determinants.
