Firstly, it supports the classic public goods theory of a trade-off-between the economic benefits of size and the costs of heterogeneity. Secondly, it rejects the “Leviathan” hypothesis because of vertical power imbalance and lack of fiscal competition among regions. Thirdly, the paper argues that government size is mediated by financial resources obtained through intergovernmental grants, consistent with welfare economics and positive economic politics. Keywords: government size, fiscal decentralization, leviathan hypothesis, vertical imbalances, flypaper effect.
