'''Fiscal federalism''' is the study of how spending responsibilities and revenue-raising powers are allocated among different levels of government, and of the economic consequences of alternative arrangements. It addresses which public functions should be performed centrally and which locally, and how intergovernmental transfers should be designed.

== Assignment of Functions ==
The classical theory of fiscal federalism, associated with Wallace Oates, holds that the provision of public goods and services should be assigned to the level of government whose jurisdiction most closely matches the geographic extent of the benefits and costs. National defence, with nationwide benefits, belongs at the central level. Local services, such as street lighting and refuse collection, belong at the local level.

The decentralisation theorem formalises this principle. Where local preferences differ, decentralised provision can match services to preferences better than uniform central provision, improving welfare. This efficiency gain from decentralisation is the central argument for a substantial local role in public finance.

== The Case for Centralisation ==
Decentralisation is not always superior. Where public goods generate spillovers across jurisdictions, local governments will underprovide them, because they do not account for benefits accruing elsewhere. Where there are economies of scale in provision, centralisation may be more efficient. Redistribution and macroeconomic stabilisation are generally better performed centrally, since mobile factors would migrate in response to local redistribution and local governments cannot conduct countercyclical policy effectively.

== Intergovernmental Transfers ==
Because local revenues rarely match local responsibilities, systems of intergovernmental transfers are pervasive. Transfers may be general purpose or conditional, tied to specific programmes. They may be designed to equalise fiscal capacity across jurisdictions, to internalise spillovers, or to secure minimum standards of service.

The design of transfers affects incentives. Conditional transfers can distort local spending priorities, and equalisation transfers can weaken the incentive to develop local tax bases. Balancing equity and efficiency in transfer design is a central challenge.

== Tax Assignment ==
The assignment of taxes follows a related logic. Taxes on mobile bases, such as capital income, are difficult to levy at the local level without inducing migration, and are better assigned to higher levels. Taxes on immobile bases, such as property, are suited to local use. Where subnational governments do levy taxes on mobile bases, competition among jurisdictions can lead to inefficiently low rates.

== Practical Experience ==
Countries differ greatly in their degree of fiscal decentralisation. Some are highly centralised, with limited subnational autonomy; others are federations with substantial devolved powers. The performance of different arrangements depends on institutional context, including the strength of accountability at each level and the capacity of local governments to manage resources effectively.

== Second-Generation Theory ==
Second-generation theories of fiscal federalism emphasise political economy and information. They analyse how decentralisation affects the incentives of politicians and bureaucrats, the accountability of governments to citizens, and the scope for experimentation and policy learning. In this view, decentralisation is not only a matter of matching jurisdictions to spillovers but also a way to create competition and accountability.

The benefits of decentralisation depend on the strength of local institutions and on the information available to voters. Where local accountability is weak or capture is possible, decentralisation may not deliver the expected improvements and may worsen outcomes.

== Soft Budget Constraints ==
A central concern in federations is the soft budget constraint, the expectation that higher levels of government will bail out subnational governments in financial difficulty. Such expectations weaken incentives for prudent fiscal management and can lead to excessive borrowing.

Institutions to harden budget constraints include clear rules on subnational borrowing, no-bailout commitments, and frameworks for insolvency and restructuring. The design of these institutions must balance the need for discipline against the risk that subnational governments are unable to provide essential services.

== Intergovernmental Competition ==
Competition among jurisdictions can promote efficiency by allowing citizens to choose where to live and firms to choose where to invest. This mobility can discipline governments, encouraging them to provide services efficiently and to avoid excessive taxation. However, competition can also lead to a race to the bottom in taxation and regulation, and to underprovision of redistributive policies.

The balance between the benefits and costs of competition depends on the mobility of factors, the extent of spillovers, and the scope of central redistribution. These considerations inform the design of transfer systems and of rules coordinating subnational policy.

== Fiscal Decentralisation and Growth ==
Empirical research on the relationship between decentralisation and growth, service delivery, and macroeconomic stability yields mixed results. The effects depend on the form of decentralisation, the capacity of subnational governments, and the broader institutional context. Decentralisation of expenditure responsibilities without corresponding revenue powers can create fiscal imbalances and dependence on transfers, while decentralisation of revenue without clarity of responsibilities can undermine accountability.
