A policymaker's guide to fiscal decentralization

Abstract

Fiscal decentralization has been an important topic among public finance economists for nearly 40 years now, but recently it has become important in the real world as well. The United States has, in effect, implemented a decentralization strategy as it has tried to cut its federal government budget deficit, largely by reducing state and local grants. For Canada, fiscal decentralization is tied up closely with the Quebec issue, and, for Germany, with the unification issue. The European Community is beginning to worry about fiscal decentralization issues in connection with policy harmonization—what policies and/or conventions should be harmonized and what need not be? Many developing countries are also groping with decentralization issues as they try to find a way to manage the public sector side of their growth process. Decentralization has always been understood to mean the proper location, by level of government, of various taxes, spending programs, grants, and regulations. What types of spending should be conducted by what levels of government, what types of taxes should be assessed by what levels of government, how should grants help fill in gaps, and how should regulations be harmonized? On the one hand, taste differences across jurisdictions argue for separate policies—governments in jurisdiction x should do what the voters in jurisdiction x want. On the other hand, the existence of benefit spillovers across jurisdictions and the potential migration of taxpayers and spending beneficiaries across jurisdictional lines make things complicated.
