Fiscal externalities and the design of intergovernmental grants

This paper describes the tax and expenditure externalities that can occur in a federation, focusing on the (relatively neglected) vertical tax and expenditure externalities which arise when state governments' tax and expenditure decisions affect the federal government's budget constraint and vice versa. Formulas are derived for matching grants which correct the distortions in governments' decision-making caused by fiscal externalities. With vertical tax externalities, the matching revenue grant may result in transfers from the state government to the federal government. With vertical expenditure externalities, the federal government should provide a matching expenditure grant equal to the additional federal revenue that is generated from an additional dollar spent by a state on productivityenhancing activities such as education.     

A Tax on Tax Revenue: The Incentive Effects of Equalizing Transfers: Evidence from Germany

Several recent studies suggest that equalizing transfers in a federal system may distort the tax policy decisions of states. We study this issue for the German federal fiscal system. In a simple theoretical model, we first identify a substitution effect and an income effect of equalizing transfers. Our main hypothesis is that both effects should tend to reduce tax revenue of German states. We perform various empirical tests which confirm this hypothesis.     

Tax Setting in a Federal System: The Case of Personal Income Taxation in Canada

In a decentralised tax system, the effects of tax policies enacted by one government are not confined to its own jurisdiction. First, if both the regional and the federal levels of government co-occupy the same fields of taxation, tax rate increases by one layer of government will reduce taxes collected by the other. Second, if the tax base is mobile, tax rate increases by one regional government will raise the amount of taxes collected by other regional governments. These sources of fiscal interdependence are called in the literature vertical and horizontal tax externalities, respectively. Third, as Smart (1998) shows, if equalisation transfers are present, an increase in the standard equalisation tax rate provides incentives to raise taxes to the receiving provinces. A way to check the empirical relevance of these hypotheses is to test for the existence of interactions between the regional tax rate, on the one hand, and the federal tax rate, the tax rate set by competing regions, and the standard equalisation tax rate, on the other hand. Following this approach, this paper estimates provincial tax setting functions with data on Canadian personal income taxation for the period 1982–1996. We find a significant positive response of provincial tax rates to changes in the federal income tax rate, the tax rates of competing provinces, and the standard equalisation rate (only for receiving provinces). We also find that the reaction to horizontal competition is stronger in the provinces that do not receive equalisation transfers.     

Sickness absence and health care in an economic federation

This paper addresses vertical fiscal externalities in a model where the state governments provide health care and the federal government provides a sickness benefit. Both levels of government tax labor income and policy decisions affect labor income as well as participation in the labor market. The results show that the vertical externality affecting the state governments’ policy decisions can be either positive or negative depending on, among other things, the wage elasticity of labor supply and the marginal product of expenditure on health care. Moreover, it is proved that the vertical fiscal externality will not vanish by assigning all powers of taxation to the states.      

Tax Evasion and Auditing in a Federal Economy

This paper analyzes the relation between tax auditing and fiscal equalization in the context of fiscal competition. We incorporate a model of tax evasion by firms into a standard tax competition framework where regional governments use their audit rates as a strategic instrument to engage in fiscal competition. We compare the region’s choice of audit policies for three different cases: A scenario of unconfined competition without interregional transfers, a scenario with a gross revenue equalization (GRS) scheme and finally, a scenario with net revenue sharing (NRS), where not only the revenues from taxation but also the regions auditing costs are shared. Without regional transfers, fiscal competition leads to audit rates which are inefficiently low for revenue-maximizing governments. While in general GRS aggravates the inefficiency, NRS makes the decentralized choice of auditing policies more efficient.JEL Code: H26, H71, H77     

The revolutions in China’s inter-governmental fiscal system

There were three periods in the development of China’s inter-governmental fiscal system. In the first period (1950s to 1979), local governments collected tax revenues and remitted upward to the central government. Reforms during the next two periods made revolutionary changes to the system. The tax-sharing system (established in 1994) provides for revenue centralization, spending decentralization, and large central transfers to local governments. This system remains largely in force.     

Tax Competition and Fiscal Equalization

This paper analyzes the relation between tax competition and fiscal equalization. In particular, it asks the question whether fiscal equalization schemes can mitigate inefficient tax competition. Two transfer schemes are considered: tax revenue and tax base equalization schemes. The paper shows that equalizing transfers may internalize fiscal externalities. In particular, in a small open economy tax base equalization yields efficient tax rates. Thus, transfer mechanisms with an explicit redistributive character do not always impair efficiency.     

Interjurisdictional Tax Competition in a Federal System of Overlapping Revenue Maximizing Governments

Academic literature in public finance has focused on interjurisdictional tax competition—namely among similar types of local governments—but has leaved vertical externalities arising from interactions between two overlapping governments sharing the same tax base aside. The purpose of this paper is to provide a simple model within which interjurisdictional tax competition and vertical interactions between two overlapping governments that share the same tax base can be analyzed simultaneously. We find that interjurisdictional tax competition reduces the global tax rate set by both overlapping governments (federal and local) but is unable to solve completely the distortion arising from vertical externalities. The model is also extended to allow for government subsidies to industrial capital. We give sufficient conditions for capital subsidies to be more efficient to attract capital when they are granted at a federal level rather than at a local level.     

Local fiscal equalisation based on fiscal capacity: the case of Austria

This paper deals with local fiscal equalisation in Austria. The system of intergovernmental relations in Austria includes different regulations in order to equalise differences in the fiscal capacity of the municipalities. This leads to so‐called ‘compensation effects’, because additional revenues from a local government's own tax are (at least partly) compensated by losses from equalisation grants. This paper carries out a detailed analysis of these compensation effects. It is shown that they create strong fiscal disincentives for the local governments: on average, 55 per cent of additional revenues from the communal tax (which is the most important of a local government's own taxes) are compensated by losses of equalisation grants. In extreme cases, local governments can lose up to 144 per cent of the additional tax yields collected. These local governments would be better off if they made no effort to increase their tax base.     

Federal tax competition and the efficiency consequences for local taxation of revenue equalization

Recent work has shown that a system of equalization grants can neutralize the efficiency loss caused by tax competition among lower-level governments. These models, however, ignore the vertical tax externalities that occur when the federal and lower-level governments levy taxes on the same base. This paper incorporates equalization grants into a standard capital tax competition model in which there are horizontal tax externalities between jurisdictions and vertical tax externalities between the levels of government. It is shown that, even in the presence of vertical tax externalities, an efficient level of lower-level government taxation can be achieved with a modifying version of a standard equalization grant formula.     

Shared Tax Sources and Public Expenditures

This paper deals with a specific vertical assignment of public functions in a federation: Two levels of government share both the same tax source and expenditure on a productivity increasing public service. We consider surplus maximizing Leviathan governments which provide public services in order to increase their potential tax base. The Nash equilibrium is characterized by overtaxation and relative to surplus maximization—depending on whether or not the public goods are sufficiently complementary with the entire tax base—either underprovision or overprovision of the public service. The implications of these results, in terms of welfare and potential use for earmarking taxes are also considered.     

Fiscal Transfers and Fiscal Sustainability

We examine whether the U.S. and German state governments pursue sustainable fiscal policies taking into account fiscal transfers. Using panel data techniques we investigate whether the debt‐to‐GDP ratio had a positive influence on the primary surplus (Bohn model). We show that including/excluding fiscal transfers changes the results. If fiscal transfers are not included in the primary surplus, the test results do not indicate that the U.S. and German state governments pursued sustainable fiscal policies. Our results also suggest that fiscal transfers were positively related to debt. These findings indicate that intergovernmental transfers have implicitly subsidized debts.     

Fiscal federalism and local public finance: A computable general equilibrium (CGE) framework

This paper attempts to make an argument for the feasibility and usefulness of a computable general equilibrium approach to studying fiscal federalism and local public finance. It begins by presenting a general model of fiscal federalism that has at its base a local public goods model with (1) multiple types of mobile agents who are endowed with preferences, private good endowments, and land endowments, (2) local governments that produce local public goods funded by a property tax, and (3) a land market that capitalizes local policies to equilibrate supply and demand. To this, a state (or national) government producing a state public good is added, and all levels of government abide by majority rule voting. A computable general equilibrium framework is derived from this theoretical model and calibrated to New Jersey micro tax data. It has been applied elsewhere to study the dominance of property in local tax bases as well as the general equilibrium effects of state or national intergovernmental programs such as redistributive grants in aid, district power equalization, and the deductibility of local taxes. Results in these areas are summarized and potential future applications discussed.

Fiscal Externalities and Efficient Transfers in a Federation

This paper investigates properties of the second best allocation in a fiscal federal system in which both federal tax and intergovernmental grants are involved and the taxation is distortionary. Also, optimal federal grants and tax policies in a decentralized fiscal system are examined. Our major findings are: (i) the second best does not require the equalization of marginal cost of public funds across regions in a conventional form; (ii) matching grants based on either the local tax rates or tax revenues should be introduced to internalize the tax externality; and (iii) once lump-sum and matching grants are optimized, federal tax policy becomes redundant so the optimal fiscal gap is indeterminate.     

Bailouts in a Federation

The recent move towards decentralization in countries such as Spain, Hungary, and South Africa and the difficulties that central governments have had in dealing with fiscal irresponsibility on the part of regional governments in countries such as Argentina, Brazil, and India has made the study of transfer systems one of the most important areas of research in federalism today. A model of a federation is developed in which regional governments act as Nash competitors with each other but are first-movers in a Stackelberg game with the central government. The central government finds that it will maximize its expected votes by increasing transfers as regions borrow. This bail out of regional governments creates a regional soft budget constraint and results in two incentive effects, a common pool effect on tax payments and an opportunity cost effect. The soft budget constraint lowers the opportunity cost of borrowing for the region, but also increases the tax-cost since a portion of the borrowing must be paid for through increased taxes. The common property problem associated with tax payments implies that the increased tax cost must be less than the decrease in the opportunity cost (leading to excessive borrowing) unless the central government increases grants to other regions when it institutes a bailout. Somewhat surprisingly, in the latter case the additional increased taxes may increase costs enough to offset the lower opportunity cost resulting from the bailout, leading to efficient borrowing decisions as in the case of a hard budget constraint. The results are also useful for understanding the empirical estimation of soft budget constraints.     

Fiscal Reconstruction and Local Government Financing

This paper investigates the dynamic properties of intergovernmental financing during a fiscal reconstruction process by analyzing the dynamic game among local governments, which operates with soft budget constraints because of concessionary region-specific transfers from a central government. The existence of intergovernmental transfers induces the free-riding behavior of local governments, thereby bringing considerable deficits to the central government. Raising local and/or national taxes is desirable for fiscal reconstruction, but is unable to attain the Pareto-efficient fiscal reconstruction. Taxes on lobbying activities, combined with uniform transfers, induce earlier concession and can attain the Pareto-efficient outcome in the long run.     

State bank transformation in Brazil – choices and consequences

This paper analyzes the different options – liquidation, federalization, privatization and restructuring – that the Brazilian state governments had for the transformation of their state banks under the PROES in the late 1990s. Specifically, this paper explores (i) the factors behind the states’ choices and (ii) the effects of the transformation process on bank performance and efficiency. We find that states that were more dependent on federal transfers, whose banks were already under federal intervention and that established development agencies, were more likely to relinquish control over their banks and its transformation process. We find that privatized banks increased their performance, while restructured banks did not.     

Local tax rebates,corporate tax burdens,and firm migration: Evidence from China

Conflicts of interest between local governments and the central administration in China have yielded many local policies that only serve the interests of local governments. The policy of first levying and then rebating taxes is an example of how local governments eschew the national tax regulations to boost local economies rather than national interests. In 2001, the Chinese government announced the termination of local tax rebates, which had some expected outcomes. We find that local governments complied with the new tax policy even though it no longer allowed local governments to grant tax incentives. However, some companies found ways to avoid the greater tax burdens by moving their business registration locations to tax havens. We also find that firms controlled by local governments were less likely to change registration locations. Our study examines the national tax regulation in China and explores how tax rules influence company decisions. In addition, we show that non-tax incentives, such as local economic development, may also influence company decisions.     

Tax competition and tax base equalization in the presence of multiple tax instruments

The literature on tax competition has argued that tax base equalization, which reduces regional disparities in tax bases, can serve as a means of internalizing horizontal and vertical fiscal externalities. This argument assumes that each government relies on a single tax base (a regional tax on mobile capital and a federal tax on savings). This paper considers the case in which a distortionary labor tax is also available. Internalizing fiscal externalities requires that while the regional capital tax base is fully equalized, a region’s equalization entitlement for the labor tax is positive when its tax base is “larger” than the average tax base of all regions. This efficient tax base equalization system is incompatible with the primary objective of fiscal equalization.
