What drives fiscal decentralisation? Further assessing the role of income

This paper investigates the determinants of fiscal decentralisation, focusing in particular on the impact of the level of income on the level of fiscal decentralisation. Various measures of fiscal decentralisation, several of them novel in this context, are employed in a cross-country econometric model to test established and more recent hypotheses. Paying careful attention to variable measurement, model specification and sample coverage, the results suggest that there are significant relationships between fiscal decentralisation and income, as well as a range of other factors. However, these relationships may be more complicated than previously reported. For the entire large sample of countries, and for the OECD subsample, a positive relationship between income and decentralisation is found. This corroborates the results found in earlier studies. However, for the middle- and lower-income nations, higher income is found to be associated with less decentralisation.
