A Note on the Composition of Public Expenditure under Capital Tax Competition

Keen and Marchand ( Journalof Public Economics, 1997, 66, 33–53) argue that undercapital tax competition, the composition of public expenditureis inefficient in that too much is spent on public inputs benefitinglocal business and too little on public goods benefiting residents.Their result depends on labor immobility. This note shows thatthe Keen-Marchand argument may not hold if both labor and capitalare mobile. An interesting case is identified where capital taxationdoes not distort the mix of public goods and public inputs, eventhough the overall level of public expenditure is inefficientlylow.     

Tax Competition, Income Differentials and Local Public Services

This paper examines strategic tax setting between fiscal authorities in the presence of mobile workers who locate across these jurisdictions in response to differing tax structures and congestable local public amenities. We find that the nature of the tax setting outcomes depend crucially on the proximity between cities. For distant cities with the same size populations, the pressure on tax rates of a more mobile workforce depends on the whether mobile workers are net beneficiaries or net contributors. If mobile workers are either high or low income earners, cities lower tax rates. If mobile workers are middle income earners, cities raise tax rates. For close or neighbouring cities, workers locate in one of the cities and tax rates and local public amenities are dispersed.     

国际税收竞争的实质及应对

国际税收竞争实质上是市场竞争规律在政府行政领域的体现形式。良性税收竞争有助于降低总体税负、减少经济扭曲、提升公共产品生产效率,但对此类竞争的国际协调难以取得实质成效。恶性税收竞争则会掠夺性地侵占他国税基,对此类竞争的遏制具备理论的必要性和可行性。政府可通过改革现行税制、精简规范收费、优化公共服务以及加强国际合作来应对国际税收竞争。     

Two Games of Interjurisdictional Competition When Local Governments Provide Industrial Public Goods

In this paper we investigate two different games of interjurisdictional competition when local governments provide public goods that benefit industry. Governments play a game either in tax rates on mobile industrial capital or in public expenditures. Although the literature suggests that competition in public expenditures is more competitive than in tax rates, this is not necessarily true in the case of industrial public goods. Moreover, in the presence of industrial public goods interjurisdictional competition may also lead to overprovision of public services.     

Some Equity and Efficiency Considerations of International Tax Competition

The paper uses a dynamic 2-country equilibrium model with imperfections in the labour market calibrated for the US and EU economy to investigate dynamic efficiency and equity aspects of international tax competition. We focus on tax policy where governments can only decide on the levels of corporate and labour taxes, given a constant share of government consumption and transfers in GDP and a constant VAT rate. We find that the welfare effect of a tax shift from capital to labour depends heavily on the distortionary nature of labour taxes. In contrast to existing results we find substantial positive international spillover effects of corporate tax reduction in one country, with long term gains outweighing short term losses. Results are very different, however, if one goes beyond the representative agent framework. According to our results, a tax switch is most likely not Pareto improving since net wages tend to decline in both regions even in the long run.     

Mixed Tax Systems and the Public Provision of Private Goods

In contrast to what used to be conventional wisdom among economists,several recent contributions have shown that in-kind transfersschemes can be welfare-improving in the presence of distortionarytaxes (usually, linear taxes or a general income tax). In thisnote, we extend previous work by considering the most generaltax system compatible with reasonable information constraints,i.e. a mix of linear indirect and non-linear direct taxes. Threemain results are noted. We find that in the presence of a mixedtax system (as opposed to the non-linear income tax alone): i) not only encouraged but also discouraged goods satisfy a conditionfor the desirability of public provision; ii) there is a tendencyfor the optimal level of in-kind transfers to be lower; iii)there is a basic equivalence between uniform and income-contingentin-kind transfers. We also show how previous results can be derivedas special cases of ours and others have to be modified to accountfor the mixed tax system.     

Optimal International Taxation and Growth Rate Convergence: Tax Competition vs. Coordination

Optimal international taxation and its implications for convergence in long run income growth rates are analyzed in the context of an endogenously growing world economy with perfect capital mobility. Under tax competition (i) the residence principle will maximize national welfare; (ii) the optimal long run tax rate on capital incomes from various sources will be zero in all countries; and (iii) long term per capita income growth rates will be equalized across countries. Under tax coordination, (i) becomes irrelevant while (ii) and (iii) will continue to hold. In other words, optimal tax policies are growth-equalizing with and without international policy coordination.

Tax Competition and Foreign Capital

This paper derives welfare equivalence of double taxation rules in a tax competition model with discriminatory home taxes and the ability to finance subsidiary operations with host country capital. For a more general model, we provide sufficient conditions on the number of host sectors and factors that support double-tax-rule equivalence. Examples violating these conditions help identify economic factors under which a home country has strict preferences over double taxation rules. If the home tax rate can influence host factor prices, the home country weakly prefers deductions over credits as in the pure-home-equity financing case.     

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.

Tax Competition and Tax Coordination in the European Union

This paper examines the tax competition literature and attempts to draw out its implications for the debate on corporate tax coordination within the EU. It begins with the early basic tax competition model, which derives conditions under which underprovision of public services occurs and tax harmonization unambiguously improves welfare for all states in the union. The paper then turns to a wide variety of extensions of this model, some of which reinforce its results and others that yield rather different conclusions. The analysis concludes by considering the implications of the tax competition literature for the debate on EU corporate tax coordination, drawing on some recent efforts to synthesize this vast literature by estimating the efficiency costs of tax competition and simulating the efficiency gains from various tax coordination palns.     

A Note on Intertemporal Fiscal Competition and Redistribution

This paper studies fiscal competition among jurisdictions in a dynamic framework, where the degree of mobility of private capital across jurisdictions boundaries is perfect. The optimal tax on mobile capital is a source tax that taxes away factor rents. Further we show that taxation of mobile capital can redistribute income in favor of the immobile factor labor. This is because the factor rents generated by public inputs and appropriated by mobile capital exceed the efficient level of public expenditure for investments. JEL Code: H21, H23, H42, H71     

公共品视角下的审计委托模式研究

现行审计委托模式是造成“独立审计不独立”,进而导致审计失败的主要原因。现代企业的“社会企业”特征,使会计报表及其审计信息具有公共品的属性,审计失败很大程度上是会计报表审计信息这一公共品私人供给模式的失败。公共品的非竞争性和非排他性特征决定了其公共供给模式较私人供给模式更有效率;税务机关作为特殊的公共部门,令其作为会计信息审计的委托人在独立性、激励和实践上更具优势。当然,会计报表审计的税务机关委托模式作为一个新的审计委托模式,其制度需不断完善。     

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.     

我国农村公共品供给分析

当前我国农村公共品的供给相对城市而言严重不足 ,但农村公共品的主要供给者———基层政府在公共品供给不足的情况下却存在严重的财政困难 ,其原因即在于我国农村公共品的供给违背了公共品供给的受益原则、公平原则和最优原则。我国应通过改革户籍制度和完善财政税收政策来优化农村公共品的供给。     

义务制教育的公共产品定位

目前,我国将九年义务制教育作为地方性公共产品,主要由地方财政提供资金,这种体制导致了一系列问题,对中国的基础教育产生了严重影响.本文从理论上和实践上提出论据,论证应将义务制教育作为全国性公共产品,由中央财政提供资金.     

税收竞争理论发展综述

上世纪80年代中后期以来,税收竞争理论研究已经成为公共经济学领域研究的重要课题之一。近年来,国外对税收竞争的研究取得了众多的研究成果。而我国的研究起步较晚,仍处于介绍与评析国外理论阶段。随着全球化进程的加快,跨国公司活动的日益活跃,国家与国家之间的联系日益密切,如何充分运用税收竞争理论完善我国涉外税收制度、维护我国在对外经济交往中的税收利益、促进我国国内经济的发展将成为以后重要的研究方向。     

Efficient Tax Competition with Factor Mobility and Trade: A Note

This note shows that residence- and source-based taxes on capital income are not sufficient to sustain an efficient Nash equilibrium when several goods are internationally traded, apart from two special cases. With several traded commodities, domestic fiscal policies affect foreign welfare not only through changes in the world interest rate but also through changes in the equilibrium relative prices of traded commodities. In order to guarantee the existence of an efficient Nash equilibrium in the general case, additional tax instruments are required. In particular, destination-based taxes on traded commodities are needed to enable the government to control the relative commodity prices faced by domestic consumers. In addition, in order to shield domestic producers from changes in world prices, the government must levy either origin-based commodity taxes or taxes on the immobile factors.     

Is Targeted Tax Competition Less Harmful than its Remedies?

Some governments have recently called for international accords restricting the use of preferential taxes targeted to attract mobile tax bases from abroad. Are such agreements likely to discourage tax competition or conversely cause it to spread? We study a general model of competition for multiple tax bases and establish conditions for a restriction on preferential regimes to increase or decrease tax revenues. Our results show that restrictions are most likely to be desirable when tax bases are on average highly responsive to a coordinated increase in tax rates by all governments, and when tax bases with large domestic elasticities are also more mobile internationally. Our analysis allows us to reconcile the apparently contradictory results of the previous literature.
