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.

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。     

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.     

加强离岸股权转让税收管理

离案股权转让涉及税种较多,本文从离岸股权转让涉及的有关税种出发,逐一剖析了离岸股权转让过程中的税收问题,并从税收政策和征管两个方面对加强离案股权转让税收管理提出了建议。     

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。     

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.

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.     

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.     

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.

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.     

税收优惠的国际竞争与影响

税收优惠竞争具有促进自由竞争、保障发展中国家的利益、保障外国投资者利益、对征税权力的约束的正面影响,也具有破坏生产效率、损害税收公平与社会福利、侵蚀其它地区的税基、破坏所得税的累进效果等负面影响。我国在新时期的税收优惠调整中,应该根据税收优惠竞争的正、负面影响综合考虑吸引投资与全民福利最大化双重因素。     

Tax Evasion and Equity Theory: An Investigative Approach

Traditional economic theory assumes rational individuals with stable preferences who, given an array of options and probabilities, maximize their expected utility. However, experimental research finds that individuals make systematic mistakes when attempting to maximize their expected utility. The economic psychology approach includes aspects of the traditional economic approach and the psychological approach that emphasizes values, attitudes, norms, conformity and morals.This paper investigates equity theory and tax evasion using the framework of prospect theory pioneered by Tversky and Kahneman. We design an investigation to identify if individual behavior follows the usual results of prospect theory, given a scenario that frames a perception of inequity. The investigation frames a scenario to invoke a controlled tax regime. The frame varies according to which inequity is being measured, exchange or social. Once the scenario is established, a questionnaire is designed to determine how the individual responds when filing taxes. The responses to the control questions are consistent with prospect theory. However, in general the responses to the framed questions, depicting inequity, are more consistent with expected utility theory.     

Exchange-of-Information Clauses in International Tax Treaties

This paper examines bilateral double taxation treaties, with an emphasis on information exchange among tax authorities. A major objective is to understand which countries are more likely to sign a tax-relief treaty and when information-exchange clauses will be added to a treaty. A simple model with two asymmetric countries and repeated interactions among governments is used. The paper shows that no information exchange clause may be added to a tax treaty when there is a reciprocity requirement, when there is a high cost of negotiation, when there is a cost of providing information, or with one-way capital flows. It is also shown that an information clause increases the gains from a tax relief treaty, but may make it less sustainable.     

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
