INTERNATIONAL TAX COMPETITION AND DOUBLE TAXATION

This paper examines international tax competition, with respect to both corporate income tax rates and tax rules for double taxation. Unlike existing studies, this study assumes that governments set non-discriminatory tax rates on domestic- and foreign-sourced corporate income and can choose no tax allowance as the tax rule. Consequently, the Nash equilibrium outcomes contradict the intuition underlying previous studies: no tax allowance is chosen as the tax rule where world economic welfare can be maximized. A capital-exporting country gains whereas a capital-importing country loses, compared to the case where there is a tax allowance of any kind.     

INTERNATIONAL CORPORATE TAX AVOIDANCE: A REVIEW OF THE CHANNELS,MAGNITUDES, AND BLIND SPOTS

This paper reviews the rapidly growing empirical literature on international tax avoidance by multinational corporations. It surveys evidence on the main channels of corporate tax avoidance including transfer mispricing, international debt shifting, treaty shopping, tax deferral, and corporate inversions. Moreover, it performs a meta-analysis of the extensive literature that estimates the overall size of profit shifting. We find that the literature suggests that, on average, a 1 percentage-point lower corporate tax rate will expand before-tax income by 1%—an effect that is larger than reported as the consensus estimate in previous surveys and tends to be increasing over time. The literature on tax avoidance still has several unresolved puzzles and blind spots that require further research.     

TAX COMPETITION

In the modern world, capital enterprise and skilled labour are increasingly mobile, and naturally attracted to countries with low taxes. Indeed tax competition can be healthy, and far preferable to a 'tax collectors' cartel.' The right of the fiscally oppressed to move themselves and their capital elsewhere is a great defender of economic freedom.     

HOW SHOULD CAPITAL BE TAXED?

This survey discusses how capital should be taxed in advanced economies. We review the theoretical optimal tax literature, survey empirical studies on the distribution of capital and the distortionary costs of capital taxation, and analyze the desirability of specific taxes on capital income, wealth, property, inheritances, and corporate profits. Our overall conclusion is that capital taxation plays an important role in an optimal tax system, but only certain ways of taxing capital are able to strike a balance between optimality and administrative feasibility.     

Local business taxation and competition for capital: the choice of the tax rate

A theoretical model describes the local choice of the tax rate on capital income. It establishes preferences and various fiscal conditions — including the tax rates of competing jurisdictions — as determinants of the tax rate. The empirical implications are tested using a large panel of jurisdictions in Germany, which have discretion in setting the local rate of the business tax. Tax competition is identified by means of instrumental variables techniques. Despite significant competition effects between local neighbors, where tax rates are strategic complements, jurisdictions are found to have some leeway in using the tax rate as an instrument of their policy. In particular, large jurisdictions set higher tax rates in interjurisdictional competition.     

NONLINEAR GROWTH EFFECTS OF TAXATION: A SEMI‐PARAMETRIC APPROACH USING AVERAGE MARGINAL TAX RATES

One of the major challenges of empirical tax research is the identification and calculation of appropriate tax data. While there is consensus that average marginal tax rates are most suitable for studying the effects of tax policy on economic growth, because of data limitations the calculation of marginal tax rates has been limited to the USA and the UK. This paper provides calculations of average marginal tax rates for the four Scandinavian countries using the methodologies of Seater (1982, 1985) and Barro and Sahasakul (1983, 1986). Then, by pooling the newly calculated tax rates for the Scandinavian countries with the data for the USA and the UK, we investigate the effects of tax policy shocks on the per capita GDP growth rate. Our results suggest that an increase in average marginal tax rates has a negative impact on economic growth. Employing additive mixed panel models with penalized splines as estimation approach, we show that changes in tax rates have nonlinear effects. Increasing average marginal tax rates turn out to be the most distorting at relatively moderate tax rates. Copyright © 2013 John Wiley & Sons, Ltd.

Lowering the Marginal Corporate Tax Rate: Why the Debate?

In an effort to attract new investors and retain existing producers, governments use corporate tax rates as a policy tool for industrial recruitment, resulting in inter‐state tax competition. Foreign direct investment (FDI) growth and GDP growth are the two policy outcomes gauged in inter‐state tax competition. The assumption is that lower corporate taxes lead to increases in FDI, which results in capital formation that generates GDP growth. This 60‐nation panel study tests that assumption through examining economic indicators contingent on taxation, such as FDI and mergers and acquisitions among multinational corporations between 1999 and 2009. The results suggest that reduced corporate tax rates can increase FDI but decrease annual GDP growth. The main policy implication is that tax competition may attract investment, but may not promote overall economic growth, offering support for value‐extraction theories.     

The heterogeneous impact of taxation on economic development: New insights from a panel cointegration approach

In this paper, we study the role of taxation on long-run income performance. In the theoretical part of the study, we develop a stylized model based on Barro (1990), in which income taxation has two contradictory roles in the standard Solow (1956) setup: on the one hand, taxation appropriates resources that would otherwise be used for physical capital accumulation, and on the other, it is the source of government spending, which is used to support private production. In the empirical part of the study, the impact of consumption tax, personal income tax, corporate profit tax and property tax on income is estimated using the common correlated effects (CCE) panel cointegration approach, which allows for cross-sectional dependencies and provides both panel- and country-specific results. The panel findings for 30 OECD countries for the period of 1995–2016 indicate that only consumption tax has a statistically significant negative effect on long-run income. However, because the type and sign of the tax coefficients are heterogeneous for the country-specific results, we conclude that taxation has heterogeneous effects on income.     

MARGINAL COMMODITY TAX REFORMS: A SURVEY

Abstract.  As noted 30 years ago by Martin Feldstein, optimal taxes may be useless for practical purposes and emphasis should instead be placed on the possibility of enhancing welfare by reforming existing tax rates. In this perspective, marginal commodity tax reforms are gaining increasing attention due to political and economic constraints on large reforms of direct (or indirect) taxation. In this paper, we summarize the main features and results of the literature on marginal commodity tax reforms pioneered by Ahmad and Stern, further developed by Yitzhaki and Thirsk and recently reinterpreted by Makdissi and Wodon. We establish new links to other fields of research, namely the literature on the use of equivalence scales and on poverty measurement. We also critically examine some issues associated with the implementation of marginal tax reforms with special reference to the calculation of welfare weights and revenue effects. Finally, we suggest directions for future research on poverty-reducing commodity tax reforms.     

A tax-based motive for the underpricing of initial public offerings

This paper presents a model of entrepreneurial wealth maximization for the pricing of initial public offerings (IPOs). It is an extension of one previously presented in the literature. The model shows that personal tax rates on ordinary income and capital gains may, in part, determine IPO pricing: an increase in the capital gains tax rate should lower the degree of underpricing. An empirical analysis of the effect of the Tax Reform Act of 1986, which raised the capital gains tax rate, shows that the average degree of underpricing did decrease as predicted, and that this occurs after controlling for other possible influences.     

CORPORATE TAX AVOIDANCE: A LITERATURE REVIEW AND RESEARCH AGENDA

Tax avoidance can range from reduction of the corporate tax burden by legitimate use of tax rules to violation of tax laws. In this paper, we endeavor to synthesize the major findings of tax avoidance research from the accounting and finance literatures over the past ten years. We consider theoretical developments and the related empirical findings about the interconnected issues of measuring tax avoidance, and the possible causes and outcomes of corporate tax avoidance. We present some ideas for further research to examine underexplored topics regarding tax avoidance.     

The interaction of corporate dividend policy and capital structure decisions under differential tax regimes

We develop a valuation model that integrates corporate capital structure and dividend payout policies. The resulting “extended” Miller (J Financ 32:261–297, 1977) model explicitly incorporates the different tax rates on corporate income, personal interest, dividends, and capital gains. We apply the model to ten different U.S. tax regimes since 1979 and generate several testable predictions. When the dividend tax rate exceeds the capital gains tax rate, dividend payout can partially offset value-enhancing effects of leverage. When the two rates are close, dividend payout loses its moderating influence. Using the S&P 1500 universe, we obtain empirical results that are consistent with the model’s predictions.     

Mobile Labor, Multiple Tax Instruments, and Tax Competition

The tax competition literature shows that local governments keep property tax rates inefficiently low to prevent capital outflows, thereby underproviding local public goods. This paper adds mobile labor and an alternative tax instrument to the model. Jurisdictions have access to a property tax levied on land and capital, plus either a head tax or a labor tax. Scale economies in public good provision create incentives to use the property tax, but these incentives are not accompanied by increased incentives to underprovide public goods. In contrast, underprovision is associated with the use of a distortionary labor tax.     

CORPORATE GOVERNANCE OF BANKS: A SURVEY

This paper reviews the empirical literature on the corporate governance of banks. We start by highlighting the main differences between banks and nonfinancial firms and focus on three characteristics that make banks special: (i) regulation, (ii) the capital structure of banks, and (iii) the complexity and opacity of their business and structure. Next, we discuss the characteristics of corporate governance in banks and how they differ from the governance of nonfinancial firms. We then review the evidence on three governance mechanisms: (i) boards, (ii) ownership structures, and (iii) executive compensation. Our review suggests that some of the empirical regularities found in the literature on corporate governance of nonfinancial institutions, such as the positive (negative) association between board independence (size) and performance, do not hold for banks. Also, existing work provides no conclusive results regarding the relationship between different governance mechanisms and various measures for banks’ performance. We discuss potential explanations for these mixed results.     

Why is there so little tax coordination? The role of majority voting and international tax evasion

It is a striking feature of EU tax policy that countries find it difficult to agree on capital tax coordination. This is in conflict with the prevailing theoretical view, according to which tax coordination is beneficial. This paper develops a political economy argument which may help to explain this puzzle. We consider a model of tax competition where fiscal policy decisions are taken via majority voting and tax evasion is possible but costly. It turns out that tax coordination agreements may fail to generate political support because middle income groups may lose from tax coordination, even if their capital income is below average.     

企业所得税对企业资本结构影响的文献综述

资本结构决策是企业发展过程中的重要决策手段,而企业所得税在企业纳税活动中占有重要的地位,企业债务融资利息可以在企业所得税前支付,即负债资金具有避税的效应,因此,在企业所得税因素的影响下,企业选择债务融资的效应更佳,二者存在一定的关联关系。论文主要从企业所得税对资本结构影响的理论研究、实证研究两个方面来对二者的关系的文献进行梳理。     

R&D INTENSITY AND THE EFFECTIVE TAX RATE: A META-REGRESSION ANALYSIS

We apply meta-regression techniques to provide a quantitative review of the empirical literature on how research and development (R&D) expenses affect the effective tax rate (ETR). R&D expenses relate to a well-accepted profit shifting channel, strategic placement of intellectual property within a multinational entity. Using a unique hand-collected data set, we add a new perspective to the current base erosion and profit shifting (BEPS) state of research and debate, in three ways: First, observing that primary studies report mixed evidence on how R&D expenses affect ETR, we provide a consensus estimate for this effect. Second, we consider this effect in more detail by separating a tax accounting effect and a profit shifting effect, which to our knowledge has not yet been investigated. We detect that one-third of the R&D effect on the ETR is due to the tax accounting effect and could be mitigated via book-tax conformity. We further find that 10% of the profit shifting effect can be traced back to R&D tax credits. Third, our meta-regression reveals factors that are possible sources of variation and bias in previous empirical studies.

Is corporate payout taxation a long run phenomenon? Evidence from international data

This paper examines whether dividend and capital gains taxation influences corporate payout policy using the country level data of 21 countries in panel versions of time series models. We find that dividend relative to capital gains tax penalty is cointegrated with corporate payouts (dividends and share repurchases) i.e. corporate payout taxation may be a long run phenomenon. Further, the cointegrating vector estimates are largely consistent with the traditional view of dividend taxation whereby the tax penalty discourages dividends, while the estimates give limited support to the premise that firms substitute dividends for share repurchases in response to an increase in dividend tax penalty. Long run causality also operates between the tax penalty and payouts in the error correction models. Additionally, dividend tax appears to be more influential than capital gains tax on dividend payout decisions. Lastly, taxation affects dividends more significantly in countries with high investor protection.
