Tax Competition and International Public Goods

A well known result in the tax competition literature is that tax rates are set too low in the Nash equilibrium to finance an efficient level of public consumption goods. In this model we introduce international spillovers in public goods provision and show that such spillovers reduce, and in the limiting case of perfect spillovers, eliminate tax competition. There is, however, always underprovision of the public good in equilibrium, since larger spillovers increase the problem of free riding. In an extension to the model, we demonstrate that congestion costs may result in overprovision of the public good.     

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 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.     

国际税收竞争、资本管制与企业所得税负担调整

在经济全球化的背景下,为争夺国际资本,各国都实行了相当优惠的公司所得税政策。但是,减税等国际税收竞争措施的作用是不确定的,一国应采取的国际税收竞争战略与其国家规模、资本管制政策等因素密切相关。面对近年来引进外国直接投资(FDI)增速放缓和逐步放松资本管制的大背景,我国必须抓住内外资企业所得税制度合并的有利时机,合理调整我国企业所得税负担。     

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.     

Tax Mimicking and Yardstick Competition Among Local Governments in the Netherlands

This paper provides a spatial-econometric analysis of the setting of property tax rates by Dutch municipalities. We find evidence of tax mimicking: a ten percent higher property tax rate in neighboring municipalities leads to a 3.5 percent higher tax rate. Mimicking is less pronounced in municipalities governed by coalitions backed by a large majority. This points to yardstick competition as the most likely source of tax mimicking. We also find that Dutch voters seem to be able to penalize incumbents for anticipated tax rate differentials, but not for unanticipated tax rate differentials. This limits the effectiveness of yardstick competition as a mechanism to reduce political rent-seeking.JEL Code: D72, H71     

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.     

Tax competition, excludable public goods, and user charges

This paper provides an explanation for the increasing reliance on revenue from user charges on excludable public goods. We develop a model with many identical countries. The government of each country imposes a source-based tax on capital and supplies an excludable public good to heterogeneous households. Without tax competition, the price on the public good is zero. Tax competition induces each country to choose a positive price. The reliance on user charges turns out to be increasing in the intensity of tax competition measured by the number of countries. A coordinated decrease in user charges is shown to raise welfare in all countries.      

解析公共税收的收入职能

税收的收入职能在人类社会不同历史发展阶段的具体表现是不同的,我们对税收收入职能的认识应该持有历史的、发展变化的观点。如何认识公共税收的收入职能,是我国公共税收建设中一个很重要的问题,因此,建议从公共税收收入职能的动因、职责范围及评判标准等方面进行全面剖析。     

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。     

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.     

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. This revised version was published online in July 2006 with corrections to the Cover Date.     

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.

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.     

论规制我国地方政府间制度外税收竞争的法治筹划

制度外税收竞争导致税收法定主义弱化,降低了市场机制对经济资源的配置效率。其法治筹划,从税收立法角度来看,要完善规范税收竞争的相关法律,提升税法立法级次,赋予地方适当税收立法权,加快费改税立法进程;从调整税收政策取向来看,要对税收优惠、区域经济协调发展、税制改革、财政转移支付等方面进行深化改革;同时,要通过强化税收执法监督、健全税收司法保障,对制度外税收竞争进行规制保障。     

Education, Mobility of Labour and Tax Competition

We show that wage-taxfinanced subsidies encourage investment in risky education andoffer welfare gains. Tax competition and labour mobility maylead to substantial erosion of regional taxation. On the otherhand, mobility insures against region-specific shocks encouraginginvestment in education. Thus, welfare effects on the educatedand the owners of the fixed factor may go in either direction.Tax competition is especially fierce if the governments careabout the owners of the fixed factor. Elimination of their interestsfrom the governments' objective functions results in a Pareto-improvementin a federation with tax competition.     

地方税收竞争中公共品供给的动态博弈及应对思路

地方税收竞争在中国具有普遍性,但与市场经济发达国家的税收竞争又存在着内容上的差异.从博弈分析来看,博弈参与主体在完全信息条件下,其最优结果是进行地方税收竞争且投入于公共品.但从中国的现实情况来看,公共品供给不足是源于制度上提供的潜在利益驱动地方政府偏离其应有责任.因此,减少政府层次、合理配给地方政府相对独立的税权、制定良好的公共支出政策是促使经济进入良性循环、地方税收竞争走向规范、有序的重要制度安排.
