Decentralization as a constraint to Leviathan: a panel cointegration analysis

This paper extends the empirical literature about the effects of fiscal decentralization on the growth of government along three dimensions. It distinguishes between the effects of the level of decentralization from the way local governments finance their expenditures (common pool versus own resources); it uses a panel cointegration approach to separate the long run effects of decentralization from the short run dynamics; and it extends and revises the datasets generally used in these empirical analyses. The results show that the amount of revenue raised by sub-national governments leads to a long-term fall in the size of government but grants have the opposite effect. In addition, a greater decentralization of expenditure leads to greater overall spending. When the short-term is considered these influences work slowly, as the speed of adjustment towards the desired government size is relatively sluggish. In addition, in the short run, there is also a clear effect from the role of local revenue raising powers that stimulates the growth of government. These results appear robust to changes in the composition of the variables, countries and periods included the sample.
