What is fiscal federalism in simple terms?

It is the theory of which public tasks and taxes are best handled by the central government and which by local governments.

Is decentralization always good?

No. When spillovers between regions are large or local governments overborrow expecting central bailouts, decentralization can cause problems.

Fiscal Federalism

📈 Economics By CampusDown Wiki Editorial Team Last updated October 27, 2026

Fiscal federalism is the field of public and political economics that asks how fiscal functions such as providing public goods, taxation and transfers should be divided between central and local governments. Wallace Oates systematized it in 1972. Its core is the decentralization theorem, which holds that because preferences vary by region, local public goods are best supplied locally; it later developed into second-generation theories stressing political incentives and institutions.

First-generation theory: assigning functions

Musgrave (1959) divided fiscal functions into allocation, distribution and stabilization, arguing that the central government should handle distribution and stabilization while local governments allocate local public goods. Tiebout (1956) argued that residents' 'voting with their feet', moving to places whose mix of taxes and services fits their preferences, leads to efficient provision of local public goods.

Oates's decentralization theorem

Oates (1972) proposed the decentralization theorem: absent interregional spillovers and major economies of scale, local governments supplying public goods tailored to local preferences is more efficient than uniform central provision. Oates (1999) synthesized the theory, covering intergovernmental grants to correct spillovers, the assignment of taxing powers and the pros and cons of interjurisdictional competition.

Second-generation theory: political incentives

Weingast (1995) proposed market-preserving federalism, under which federalism restrains state predation and preserves markets when subnational governments hold primary economic authority, a common market is ensured and budget constraints are hard. Qian and Weingast (1997) argued that China's decentralization reforms had this effect. Rodden (2006) highlighted the soft budget constraint problem, in which local governments that expect central bailouts overborrow, concluding that the effects of decentralization depend on institutional design.
