How Profit Shifting May Increase the Tax Burden of Multinationals: A Simple Model with Discrete Investment Choices

This paper models a Stackelberg tax setting game between two revenue‐maximizing countries which compete for the location of a single production plant owned by a multinational firm. We introduce the possibility of profit‐shifting activities by the multinational firm and investigate how a change in the costs of profit shifting affects equilibrium tax rates, revenue, and the tax burden of the multinational firm. We show that in most cases, tax rates of the two countries will be higher under profit shifting than without. If the costs for profit shifting are not too low, the strategic adjustment of profit tax rates will typically harm the multinational firm.     

Capital and Consumption Tax Reforms in a Small Open Economy

The effects of a reform in capital and consumption taxes on private welfare and government tax revenue are examined for a small open, capital‐importing economy. A trade‐off between private welfare and tax revenue is encountered in maximizing social welfare. Nonetheless, lowering capital taxes and raising consumption taxes can increase both private welfare and tax revenue if the initial tax rates are not optimal. In addition, a tax reform by this fashion is a likely response to a rise in the foreign rate of return on capital.     

Volatile Mining Revenues and State Government Budget Decisions

Mining royalties provide a volatile source of revenue for state governments in Australia. We explore the effects of changes in royalty revenue received by a state government on current-year budget decisions about expenditure, tax revenue and the budget surplus. The literature postulates different models for how lower-level government budget decisions respond to a revenue windfall from a higher level of government. Empirical evidence on these models over 1998–2019 provides strong evidence that over a half of a royalty windfall becomes a change in budget expenditure. Estimates of changes to tax revenues and the surplus are not definitive nor robust.     

Tax Evasion,Corruption and Tax Loopholes

This paper addresses tax loopholes that allow firms to exploit borderline cases between legal tax avoidance and illegal tax evasion. In general, tax loopholes are detrimental to a revenue‐maximizing government. This may change in the presence of corruption in the tax administration. Tax loopholes may serve as a separating mechanism that helps governments maximize revenues and curb corruption, which may explain why developing countries only gradually close loopholes in their tax codes.     

Asymmetric Capital Tax Competition with Profit Shifting

This paper analyses capital tax competition between jurisdictions of different size when multinational firms can shift some fraction of their tax base between them. For the case of revenue maximizing governments, we show that introducing profit shifting will not generally increase downward pressure on tax rates. We find that profit shifting decreases the tax-base sensitivity of the low tax jurisdiction while increasing the sensitivity of the high tax jurisdiction. Tax rates will converge as a result of additional profit shifting opportunities. This will be the case even though in general equilibrium tax rates in both jurisdictions may decrease or increase.     

Revising the conventional tax-effort principle

The standard methodology on tax-effort (i.e., the ratio of actual tax revenue to its optimal level) is to run a regression of actual tax revenue on countries’ specific (macroeconomic, demographic, geographical, political, social, and institutional) variables. The resulting predicted (fitted) values are then taken to represent the optimal (desired or maximum) level of tax revenue. The crucial issue of tracing out how the optimal tax revenue should be allocated to the fiscal objectives (equity, efficiency) does not seem to be of any interest to the researchers on tax-effort. The present paper argues that the standard methodology is not without faults and needs revising. We demonstrate that an optimal tax system can be safely derived from maximizing a utility function with respect to (in)direct tax rates. The manipulation of the first-order conditions, using a novel mathematical module, leads to an infinite number of optimal direct–indirect tax rates. The selection of the optimal mix of these tax rates is dependent on the country-specific households’ preferences over equity/efficiency, as they are formulated by voters’ volition in election periods. A simulation procedure helps understanding how the optimal tax revenue is chosen and how it can be optimally allocated to fiscal objectives, in the context of a panel data set including a large number of developed and developing countries. Throughout our text, the optimal tax revenue is defined as the sum of the products of the optimal (in)direct tax rates and their corresponding tax bases. In the simple Arrow–Debreu economy, the above sum is shown to be equal to the difference between income and consumption.     

Revenue‐enhancing Trade Liberalization in a Differentiated Duopoly

Existing studies suggest that in developing countries, tax reforms that increase consumption taxes can compensate for shortfalls in revenue from a tariff reduction. However, these revenue‐enhancing tariff–tax reforms have a critical shortcoming—they generally reduce welfare under imperfect competition. This paper shows that tax reforms such as consumption tax reforms do not necessarily have to be implemented to make up for revenue shortfalls from tariff reductions under imperfect competition, because trade liberalization through tariff cuts leads to an increase in government revenue when domestic and imported goods have a high substitutability. This revenue‐enhancing effect of a tariff reduction occurs for a wider degree of product substitutability when initial tariff and consumption tax rates are high. More importantly, we show that even if initial tariff and consumption tax rates are sufficiently low, a tariff reduction still increases government revenue for a low degree of product differentiation under Bertrand competition.     

通货膨胀、政府收益与社会福利损失

传统"Cagan规则"认为,政府通货膨胀税收益最大化的条件是,通货膨胀率应该为(货币需求关于)利率半弹性的倒数。这一规则是局部均衡条件下的结果,并未考虑通胀的实际经济效应。本文基于交易成本方法在一般均衡框架内讨论收益最大化时通货膨胀率的决定问题。该框架中收益最大化的通货膨胀率小于Ca-gan规则值,这一结论得到了中国1945—1949年恶性通胀时期经验数据的支持。经验结果还表明,相对于Cagan规则,根据交易成本方法设定的通货膨胀率尽管并没有明显提高政府的通货膨胀税收益,却大幅降低了社会福利损失。     

Intra-Jurisdictional Tax Competition

While much has been written about inter-jurisdictional competition for tax revenues, especially concerning the choice between harmonization and competition, the literature has largely ignored intra-jurisdiction issues. The few articles examining this issue focus on how lower level governmental entities react to the tax decisions of a national government. However, in some instances, multiple co-equal taxing authorities might share the same base. These bodies face a dilemma over whether to harmonize their policies or to compete. We present a simple model of revenue maximizing tax authorities and derive the conditions under which harmonization dominates competition.     

Tax Reform with Useful Public Expenditures

We examine the effects of tax reform in an endogenous growth with two types of useful public expenditures. The optimal fiscal policy shifts the tax base to private consumption and generally requires a change in the size of government. If a tax reform holds the size of government fixed to satisfy a revenue‐neutrality constraint, then the reform will be suboptimal; theory alone cannot tell us if welfare will be improved. For some model calibrations, we find that a revenue‐neutral consumption tax reform can result in large welfare gains. For other quite plausible calibrations, the exact same reform can result in tiny or even negative welfare gains as the revenue‐neutrality constraint becomes more severely binding. Overall, our results highlight the uncertainty surrounding the potential welfare benefits of fundamental tax reform.     

Imperfect Capital Mobility and Local Government Behaviour in a Two‐Period Economy

One clear result in the tax competition literature is that, when head taxes on immobile residents are available, the optimal capital tax rate for local government is zero. However, zero tax rate, when resident taxes are available, is incompatible with the phenomenon actually observed. In most countries, local governments use capital taxes as policy variables for choosing a nonzero tax rate. This paper presents a model of a two‐period economy with imperfect mobile capital to explain the behaviour of local government providing capital subsidies on capital. It further examines an equilibrium tax rate where local government’s objectives include Niskanen‐type revenue‐maximizing.     

Public investment,taxation, and long-run output in economies with multi-level governments

This paper examines the dynamic effects of taxation and investment on the steady state output level of an economy. A simple neoclassical growth model with different tiers of government is developed. The initial focus is on governments that aim to maximise their citizens' welfare and economic performance by providing consumption goods for private consumption and public capital for private production. It is shown that a long-run per capita output maximising tax rate can be derived and that there also exists an optimal degree of fiscal decentralisation. The analysis then extends to the case where governments attempt instead to maximise their own tax revenue to fund expenditures which do not contribute to the utility of their citizens. Three different cases of taxation arrangement are considered: tax competition, tax sharing, and tax coordination. The modeling shows that intensifying tax competition will lead to an increase in the aggregate tax rate as compared to the cases of sharing and coordination amongst governments. These tax rates are both higher than the long-run per capita output maximising rate that was implied under the welfare maximising government scenario.     

Commodity Taxation and Economic Growth

We construct a variety expansion growth model following Grossman and Helpman (1991) and incorporate various groups of goods into the model. Each group has its own elasticity of substitution. We seek to determine the goods on which the government should impose higher rates of commodity tax in order to raise a certain amount of tax revenue. We thus reconsider the Ramsey Rule (the Inverse Elasticity Rule) in a growing economy.     

Why Do Poor democracies Collect a Lot of Tariff Revenue?

Governments in developing countries typically collect a significantly higher proportion of their revenue in the form of trade taxes, than their developed country counterparts. This paper provides a political–economic explanation for this phenomenon. A model of trade in vertically differentiated products is used in order to determine the preferences of the households among different ways of raising government revenue. It is shown that the majority of households in poor countries will consume low-quality, domestically produced varieties of differentiated products and would thus register a preference for the government to rely more on tariff rather than income tax revenue in order to finance its operations.

Political competition,tax salience and accountability. Theory and evidence from Italy

This paper argues that electoral competition may hinder rather than foster political accountability, especially when elected officers can choose among a number of tax instruments. We develop a political agency model showing that politicians in more competitive jurisdictions use less salient tax instruments more intensely. Defining salience as visibility or, analogously, as voters' awareness of the costs associated with specific government revenue sources, we argue that voters are less likely to hold politicians to account for the associated tax burden of a less salient instrument. This in turn implies that strategic politicians will more heavily rely on less salient revenue sources when electoral competition is stronger. Using data on Italian municipal elections and taxes over a 10-year period, we determine the degree of salience of various tax instruments, including property taxes (high salience) and government fees for official documents (low salience). We then show that mayors facing stronger competition for re-election use less salient tax instruments more intensely.     

政府阶段性政策偏好对税收公平的影响

我国政府在改革开放之初与社会主义市场经济秩序基本建立的两个不同发展阶段,选择了不同的企业所得税政策偏好,通过企业身份设计、税率和优惠措施安排,在促进经济发展同时,对税收公平也产生了程度不一的侵蚀。但政府阶段性政策偏好对税收公平的侵蚀并不具有当然的合理性,在企业所得税法中必须做出精当的制度设计,尽可能减轻或减缓政策偏好对税收公平的侵蚀。     

人口流动性、公共收入与支出--户籍制度变迁动因分析

本文分析了人口流动性的内生决定 ,以此解释中国户籍管理政策变迁的动因。文章表明 ,分权框架下的区际竞争将推动政府降低人口流动成本。一般而言 ,集权 ①框架下的最优流动性水平普遍低于分权框架下的流动性水平。与我国近 2 0年来户籍政策变化相一致的是 ,跨区劳动力配置需求的上升增加了户籍管制的效率损失成本 ,将推动人口流动成本下降。我们认为 ,除了协调地方公共品供给外部性、限制地区间税收竞争以最大化税收收入这两个基本原因之外 ,我国户籍管制的另一个特殊原因是便于执行地区差别政策。而设置流动成本的效率性取决于政府目标与社会福利最大化的一致性程度。     

Equity,efficiency, and the structure of indirect taxation

Optimal tax formulae are derived and optimal tax rates calculated for the case where there are many consumers, an income tax is impossible and the government has to trade off efficiency in order to improve the real distribution of income. Consistent aggregation assumptions are used to permit the derivation of simple tax rules depending only on the behaviour of the average consumer and of a socially representative consumer. Calculations for the U.K. in 1972 show how subsidies and taxes vary with the government's revenue requirement and with the degree of egalitarianism in the social welfare function.     

THE DECLINE OF CHINA'S BUDGETARY REVENUE: REASONS AND CONSEQUENCES

The decline of the government revenue share in GDP has become a major concern for Chinese policy makers and many economists. This article analyzes the reasons and the consequences of low government budgetary revenue in China. It is argued that lowered corporate tax rates, small tax bases, and tax evasions are the main reasons for the decline of government revenue share in GDP. Low budgetary revenues have resulted in low budgetary expenditures and growing budget deficits, stimulated the expansion of extra-budgetary and off budgetary revenues, and made the privatization of state enterprises more difficult. This article also discusses policy options for China.
