Optimal fiscal decentralization: Redistribution and welfare implications

The literature has been inconclusive regarding the welfare effects of fiscal decentralization (FD), defined here as the extent to which local governments collect and spend local tax revenues. We present an original model to investigate formally the distributional and welfare implications of FD. In contrast to the standard approach that compares the implications of full FD with that of centralization, we consider that the central government chooses the level of FD to maximize welfare in a heterogeneous country. Noncooperatively, local governments choose their tax collection effort to maximize local utility. We show that an increase in the tax rate leads optimal FD to increase so as to compensate for the welfare loss from decreasing optimal local tax effort. Hence, welfare and income distribution improve in FD at its intermediate, rather than extreme, levels. We coin this result as the decentralization-Laffer curve. As regional spillovers increase, FD is less desirable as it deteriorates welfare and income distribution. This finding provides a novel support for the decentralization theorem and contributes to the fiscal policy debate.     

The incentive effect of fiscal equalization transfers on tax policy

A theoretical analysis considers the impact of a typical system of redistributive “fiscal equalization” transfers on the tax effort of local jurisdictions. More specifically, it shows that the marginal contribution rate, i.e. the rate at which an increase in the tax base reduces those transfers, might be positively associated with the local tax rate while the volume of grants received is likely to be inversely related to the tax rate. These predictions are tested in an empirical analysis of the tax policy of German municipalities. In order to identify the incentive effect the analysis exploits discontinuities in the rules of the fiscal equalization system as well as policy changes. The empirical results support the existence of an incentive effect, suggesting that the high marginal contribution rates induce the municipalities to set significantly higher business tax rates compared with a situation without fiscal equalization.     

Tax havens,income shifting,and redistributive taxation

This paper investigates the effects of tax havens on nonhaven countries’ redistributive policies. We consider that a nonhaven country contains individuals with different labor productivities. A tax is imposed on the income, and the revenues are evenly distributed. The tax rate is determined by majority voting, which reflects the median voter’s preferences. The presence of havens gives rise to the mobility of tax bases, which may increase the nonhaven country’s tax rate in two ways. First, it leads to a median voter with a lower productivity; second, it may enlarge the marginal tax revenue from raising the tax rate. In addition, we find that a stricter antihavens regulation may lower the tax rate. We further show that income shifting is likely to reduce the amount of the transfers. The case of tax evasion is also taken into consideration.     

Revisiting the redistribution effects of intergovernmental fiscal transfers: evidence from Taiwan

This paper employs a panel of 23 local governments in Taiwan over 1998–2010 to re-estimate the redistribution effects of intergovernmental fiscal transfers by considering a self-financing resources of local government as the transition variable in panel smooth transition regression models. Empirical results show that the income (or tax revenues) redistribution effects of fiscal transfer policies are nonlinear and vary with time and across local governments. The grants from central government can improve income and tax revenues distribution of local governments; however, the centrally allotted tax revenues have inverse effects and the total fiscal transfers have ambiguous effects. The total fiscal transfer is a proper policy instrument for improving income redistribution, and the grants for improving tax revenues redistribution. However, high self-financing resources ratios are harmful for these redistribution effects.     

对新疆财政收入状况的分析与判断

近年来我国财政收入增长快于经济增长这一现象引起了世人的普遍关注，并由此引发了对财政收入与经济增长是否协调、企业负担是否加重等问题的思考。从税收负担、地方政府可支配财力、转移支付的公平效果进行分析，可得出结论：新疆财政收入增长过快的同时也加重了企业负担，且受新疆特定产业结构和分税制的影响，地方财力有所削弱。对此应当从产业政策和完善转移支付制度等方面进行调整。     

Resource discovery and the politics of fiscal decentralization

If the central government is a revenue maximizing Leviathan then resource discovery and democratization should have discernible impacts on the degree of fiscal decentralization. We systematically explore these effects by exploiting exogenous variation in giant oil and mineral discoveries and permanent democratization. Using a global dataset of 77 countries over the period 1970–2012 we find that resource discovery has very little effect on revenue decentralization but induces expenditure centralization. Oil discovery appears to be the main driver of centralization and not minerals. Resource discovery leads to centralization in locations which have not experienced permanent democratization. Tax and intergovernmental transfers respond most to resource discovery shocks and democratization whereas own source revenue, property tax, educational expenditure, and health expenditure do not seem to be affected. Higher resource rent leads to more centralization and the effect is moderated by democratization.     

The Financing of Foreign Aid and Welfare: Income Versus Consumption Tax

Empirical evidence shows that developed countries use income or consumption taxes to generate tax revenue, of which they transfer a certain fraction as aid to less developed countries. This paper constructs a two-country general equilibrium trade model that takes into account these realities, and examines the terms of trade, employment and welfare effects of international transfers when the donor country increases the fraction of its income or consumption tax revenue transferred as aid. The desirability of each method of aid financing is discussed from the viewpoint of national and world welfare, and conditions are identified under which aid improves world welfare with the one method of financing, and may worsen it with the other.     

The general equilibrium effects of fiscal policy: Estimates for the Euro area

This paper describes a dynamic stochastic general equilibrium model featuring a fraction of non-Ricardian agents in order to estimate the effects of fiscal policy in the Euro area. The model takes into account distortionary taxation on labor and capital income and on consumption, while expenditures are broken down into purchases of goods and services, compensation of public employees and transfers to households. A newly computed quarterly data set of fiscal variables is used. Our results point to the prevalence of mild Keynesian effects of public expenditures. In particular, although innovations in fiscal policy variables tend to be rather persistent, government purchases of goods and services and compensations for public employees have small and short-lived expansionary effects on private consumption, while innovations in transfers to households show a slightly more sizeable and lasting effect. The effects are more significant on the revenue side: decreases in labor income and consumption tax rates have sizeable effects on consumption and output, while a reduction in capital income tax favors investment and output in the medium run. Finally our estimates suggest that fiscal policy variables contribute little to the cyclical variability of the main macro variables.     

EFFECTS OF TAXES AND BENEFITS ON INCOME DISTRIBUTION IN KOREA

This paper examines the redistributive effects of Korea's fiscal policies, including consumption taxes and in‐kind benefits. Using the Household Income and Expenditure Survey of 2007, we find that taxes and transfers reduce income inequality in Korea by 13.8 percent. Contrary to the popular belief that direct taxes are the key tool for redistribution, in‐kind benefits, direct taxes, and social security contributions all decrease the Gini coefficient by 6.7, 4.7, and 2.9 percentage points, respectively. The redistributive effect of consumption taxes is small and negative (?0.5 percentage point). Policy simulations indicate that education spending financed by the personal income tax has a positive redistributive effect and that the lower 70 percent of households enjoy positive net benefits. Spending targeting the poor has a strong redistributive effect, which implies low popularity because the majority of households face net losses.     

中国均衡性转移支付对地方政府收入行为的激励效应评估*——基于动态空间工具变量与空间杜宾模型分析

本文基于全国县级面板数据，采用动态空间工具变量模型和空间杜宾模型，从地方政府收入行为视角对均衡性转移支付的激励效应进行评估。结果表明：均衡性转移支付对地方政府收入行为具有双重作用。在直接效应方面，其在一定程度上缓解了地方政府的财政压力，且不会对地方政府造成直接税收扭曲影响。但在间接效应方面，均衡性转移支付会引致地区间扭曲的税收竞争。其产生的税基效应和税率效应相互抵消，对地方政府的征税努力的影响不显著，对地方政府的财政收入行为呈现中性影响，并未产生正向激励效应。

The suboptimality of local taxation under two-tier fiscal federalism

Increased taxation in a single, local jurisdiction changes the tax base of the national as well as the local government. Changes in national-government tax revenue then affect citizens in other jurisdictions. Local fiscal decisions, which neglect such national spillovers, are suboptimal. If factor supply decreases with the local tax rate, a reduction in tax-financed spending on local-government goods increases welfare. A reduction in tax-financed local-government redistributions increases welfare generally.     

Markets as beneficial constraints on the government

We study the role of anonymous markets in which trades cannot be monitored by the government. We adopt a Mirrlees approach to analyze economies in which agents have private information and a benevolent government controls optimal redistributive tax policy. While unrestricted access to anonymous markets reduces the set of policy instruments available to the government, it also limits the scope of inefficient redistributive policies when the government lacks commitment. Indeed, the restrictions that anonymous markets impose on the optimal fiscal policy, especially on capital taxation and the history-dependence of income taxation, can have positive welfare effects in this case.     

Global capital markets,direct taxation and the redistribution of income

Standard fiscal theory suggests that taxation should be heaviest on the least mobile factors of production – for both efficiency and revenue reasons. A shift in tax burdens from capital to labour as economies become globally integrated is thus justified. This theoretical tradition (founded by Ramsay and continued by Mirrlees and Lucas) assumes by construction that profit taxes reduce investment and growth; and while sensitive to inter-generational equity, sidesteps the issue of income distribution within generations. In contrast, starting from Keynes’ critique of these assumptions and building on modern endogenous growth models, it can be shown that profit taxation is not necessarily injurious to productive investment. In practice, moreover, the effect of globalisation has not been to reduce tax rates on capital, but rather to erode the tax base itself (i.e. ‘tax evasion’). Improved information exchange between tax authorities, which is now being driven by fiscal insolvency in developed countries, would allow tax incidence to be shifted so as to improve income distribution within OECD countries. Such cooperation could also permit the replacement of the current discretionary system of fiscal transfers from rich to poor countries (‘development aid’) by equitable sharing of global capital tax revenue.     

Dynamic scoring of tax reforms in a small open economy model

We examine dynamic revenue effects of a permanent tax cut on labor and capital income using a small open two-sector dynamic general equilibrium model. We use a dynamic scoring technique to calculate long-run as well as transitional effects on fiscal revenue when a tax cut is financed by either a lump-sum tax or consumption tax. We show that the revenue loss from an income tax cut becomes substantially smaller when agents can use international financial markets compared to the case of the closed economy. Responses of tradable and nontradable sectors to the capital income tax cut display a stark contrast in both long-run equilibrium and transitional dynamics due to different factor intensities. Capital income tax cut in the tradable sector is the most efficient policy instrument in terms of minimizing fiscal revenue loss. These simulation results suggest that fiscal sustainability issue when implementing a tax cut could be overstated.     

Fuel for inequality: Distributional effects of environmental reforms on private transport

This paper provides the first empirical evidence of the distributional effects of subsidies for the purchase of alternative vehicles based on an extended version of Hausman's exact consumer surplus. In consistence with economic theory, we estimate changes in household welfare, inequality, and social welfare resulting from different reforms. First, we find that an additional tax on conventional fuel is regressive. However, returning the additional tax revenue via lump-sum transfers can alleviate this effect. Second, when the additional revenue is also used to finance subsidies for electrical and compressed natural gas (CNG) vehicles, households that own such vehicles experience welfare gains. However, this policy also increases income inequality and decreases social welfare.     

我国企业所得税征管效率测度分析

高效的税收征管是良好税制的重要内容和保障,也是税制改革成功的基本条件。本文在对2000年以来我国企业所得税征管效率测度的基础上,进一步分析了近年来我国企业所得税及征管制度改革的征管效应。研究发现,近年我国企业所得税征管效率呈波浪式上升态势,效率水平还有较大提升空间;在当前情况下,国税局企业所得税征收比重的提高将会降低企业所得税征管效率,企业所得税占税收收入比重越高、在税收部门征管中越重要,就更有助于企业所得税征管效率的提升;2002年、2006年和2009年企业所得税、国地税征管责任分工调整改革,对税收征管效率的影响不显著,2008年内外资企业所得税统一改革,显著提升了企业所得税征管效率。     

Tax revenue and the marginal cost of public funds in Sweden

We assess the welfare cost of raising a marginal unit of tax revenue in a balanced-budget, general-equilibrium framework. The calculated social cost of an increment of public funds is sensitive to both the specific type of tax increase and the type of public spending used on the margin. ‘Best-guess’ assumptions on labor supply elasticities yield marginal costs of public funds for different fiscal mixes of between 0.67 and 4.51 at prevailing tax rates in Sweden. Alternative labor supply assumptions well within the range of current estimates substantially affect the results and can imply infinite marginal welfare costs. Marginal welfare costs are also sensitive to assumptions about both the income and substitution effects of labor supply.     

Striking a balance: Optimal tax policy with labor market duality

We develop a dynamic general equilibrium model where employers may avoid making social security contributions by offering some workers “secondary contracts.” When calibrated using aggregate tax revenue data, the model delivers estimates of secondary “off the books” employment that are consistent with survey evidence for the EU14 and United States. We investigate the fiscal and welfare effects of varying the avoidable and unavoidable shares of labor income tax while keeping the total wedge constant, and find that increasing the employer component raises hours worked, output, and welfare. Partial labor tax evasion makes tax revenues more elastic, but full tax compliance need not be a welfare enhancing policy mix.
