Leviathans, Federal Transfers, and the Cartelization Hypothesis

Federal fiscal arrangements are argued to give rise to tacit collusion among competing Leviathans (Brennan and Buchanan, The Power to Tax, CUP, 1980). Though frequently encountered in academic and policy discussions, the cartelization hypothesis has rarely been scrutinized formally. This paper explores the effect of federal equalizing transfers on Leviathans engaged in tax competition. Contrary to the hypothesis, equalization is found to potentially complement tax competition in taming the Leviathan by implicitly taxing tax revenues extracted by the Leviathan. Thus, transfers might be an appropriate constitutional provision against fiscal expropriation.JEL classification: H7, H1, H20Leviathan, fiscal transfers, fiscal competition, federalism, constitution

Tax Competition in a Fiscal Union with Decentralized Leadership

This paper examines capital tax competition in the presence of an interstate transfer policy without federal commitment. Lack of commitment implies that tax policy is chosen prior to federal transfers. The paper’s main result is that ex-post federal policy internalizes horizontal fiscal externalities, insulating tax policy from capital mobility. Federal policy, however, introduces a new source of inefficiency unrelated to tax competition. Specifically, ex-post transfer payments prove to be equivalent to an interstate revenue-sharing system which may render federal intervention in the presence of fiscal externalities welfare-deteriorating relative to tax competition.federalism, capital tax competition, commitment, soft budget constraints

Government Spending and Legislative Organization: Quasi-experimental evidence from Germany

This paper presents empirical evidence of a positive effect of council size on government spending using a data set of 2,056 municipalities in the German state of Bavaria over a period of 21 years. We apply a regression discontinuity design to avoid an endogeneity bias. In particular, we exploit discontinuities in the legal rule that relates population size of a municipality to council size to identify a causal relationship between council size and public spending, and find a robust positive impact of council size on spending. Moreover, we show that municipalities primarily adjust current expenditure in response to a rise in council size.Legislative organization; Regression-discontinuity design; Government spending; Mayor-council system

Social Security Reform and Intergenerational Trade: Is there Scope for a Pareto-Improvement?

In earlier literature, the suggested Pareto improvements in pay-as-you-go (PAYG) systems have relied on the presence of externalities or the possibility of intragenerational redistribution. We show that neither assumption is necessary in an economy with intergenerational trade in a fixed factor of production, here labeled as land. Reducing the social security tax rate encourages investment in complementary human capital. Future efficiency gains accruing to land are capitalized in its value which compensates the land-owning pensioners for reduced benefits. We also explain why the PAYG system may have lost its appeal even for pensioners after its introduction.social security reform, fixed factor, pay-as-you-go system, capital gains taxation

Ex-post redistribution in a federation: implications for corrective policy

This paper analyzes whether changes in the timing of equalizing transfers to state governments necessitate an adjustment in federal corrective policy. According to the existing literature (assuming an ex-ante choice of transfers), the corrective grant is equal to the marginal damage/benefit inflicted by externality generation. When the federal government accommodates state finances ex-post, the grant differs in formula from existing prescription. Allocative federal policy corrects state policy incentives twofold. It entails a correction for the distortion in the marginal benefit of state spending (as in earlier literature) and for the distortion in the marginal cost of public funds induced by the ex-post provision of transfers. The required grant rule is generically disproportionate to the equilibrium externality (even with lump-sum taxation). Furthermore, the ex-post provision of transfers is critical for the nature of the equilibrium inefficiency. Equalizing transfers at least partly internalize consumption spill-overs, but simultaneously establishes a new source of inefficiency. As a final result, the existing prescription for allocative federal policy continues to apply if the public good is pure

Revisiting the decentralization theorem: on the role of externalities

The Decentralization Theorem (Oates, 1972) is central to the discussion of fiscal federalism. We revisit the role of consumption spillovers in evaluating the merits of (de)centralization. Unlike the general prediction, a higher degree of spillovers may reduce the difference in utility of centralization and decentralization. The non-monotonicity result relates to the difference in expenditures on public consumption. Provided decentralized choices yield higher levels of public expenditure, a rise in the amount of spillovers allows residents to enjoy larger gains in public consumption (and thereby utility) under decentralization relative to centralization

Federal tax-transfer policy and intergovernmental pre-commitment

Federal and state governments often differ in the capacity to pre-commit to expenditure and tax policy. Whether the implied sequence of public decisions has any efficiency implications is the subject of this paper. We resort to a setting which contrary to most of the literature does not exhibit a perfect tax-base overlap. We show that a federal government's pre-commitment capacity is welfare-improving. Efficiency, however, does not improve over all decision margins. The welfare-increasing policy entails a more distorted level of public consumption. Moreover, welfare may also improve if local governments are able to pre-commit towards the upper level. The rationale is that although federal transfers are formally unconditional they nevertheless entail a tax-price effect; thereby potentially counteracting incentives to engage in a race to the bottom in fiscal competition among local governments

Does Tax Competition Really Promote Growth?

This paper considers the relationship between tax competition and growth in an endogenous growth model where there are stochastic shocks to productivity, and capital taxes fund a public good which may be for final consumption or an infrastructure input. Absent stochastic shocks, decentralized tax setting (two or more jurisdictions) maximizes the rate of growth, as the constant returns to scale present with endogenous growth implies “extreme” tax competition. Stochastic shocks imply that households face a portfolio choice problem, which may dampen down tax competition and may raise taxes above the centralized level. Growth can be lower with decentralization. Our results also predict a negative relationship between output volatility and growth, consistent with the empirical evidence.tax competition ; uncertainty ; stochastic growth
