Centralized versus decentralized provision of local public goods: a political economy approach

This paper takes a fresh look at the trade-off between centralized and decentralized provision of local public goods. It argues that the sharing of the costs of local public spending in a centralized system will create a conflict of interest between citizens in different jurisdictions. When spending decisions are made by a legislature of locally elected representatives, this conflict of interest will play out in the legislature. Depending on precisely how the legislature behaves, the result may be excessive public spending or allocations of public goods characterized by uncertainty and misallocation across districts. The extent of the conflict of interest between districts is affected by spillovers and differences in tastes for public spending. Thus, the relative performance of centralized and decentralized systems depends upon spillovers and differences in tastes for public spending, but for different reasons than suggested in the existing literature.
