The ability of deferred tax to predict future tax

We examine the usefulness of tax allocation accounting (deferred tax) for predicting future tax paid and future tax expense. Deferred taxes increase the explanatory power (R²) of regression models where future taxes paid or future tax expense is the dependent variable. However, the mean out‐of‐sample forecast errors for tax paid (future tax expense) is 30 (45.5) percent. Deferred tax increases predictive ability on pooled data, but is inconsistent on a year‐by‐year basis. We examine three explanations for poor predictive ability: losses, tax changes and asset growth. We discuss the policy and practical implications of our findings.     

Multiple taxes and alternative forms of FDI: evidence from cross-border acquisitions

This paper explores the role of tax instruments in affecting foreign direct investment (FDI), paying particular attention on their effect on two forms of FDI strategy, ‘horizontal’ and ‘vertical’. Applying a decomposition of FDI strategies to the universe of cross-border mergers (the dominant form of FDI) over the period 1999–2010, it emerges that taxes have a much more nuanced effect on FDI than frequently suggested; while corporate taxes affect FDI negatively, the tax elasticity varies depending on the FDI strategy (with vertical FDI being in general more responsive), the exact measure of taxation, and international tax considerations (double taxation, withholding taxes). Sales taxes also affect FDI, but only horizontally.     

全球化和发展中国家财政改革的必要

全球化为发展中国家带来压力，促使他们增加公共支出以改善国家的基础设施，改进制度，弥补为了纠正错误政策而支付的最终成本，补偿某些在迅速的全球化中受到最大影响的群体，对其中的一些人进行再培训，用最基本的现代保障网络去取代传统的简单无效的社会保障体系。各国应首先努力提高公共税收的使用效率，然后改革其税制，通过征收个人所得税和增值税，尤其是后者，来提高税收。     

Sharing Risk with the Government: How Taxes Affect Corporate Risk Taking

Using 113 staggered changes in corporate income tax rates across U.S. states, we provide evidence on how taxes affect corporate risk‐taking decisions. Higher taxes reduce expected profits more for risky projects than for safe ones, as the government shares in a firm's upside but not in its downside. Consistent with this prediction, we find that risk taking is sensitive to taxes, albeit asymmetrically: the average firm reduces risk in response to a tax increase (primarily by changing its operating cycle and reducing R&D risk) but does not respond to a tax cut. We trace the asymmetry back to constraints on risk taking imposed by creditors. Finally, tax loss‐offset rules moderate firms’ sensitivity to taxes by allowing firms to partly share downside risk with the government.     

Effective labor taxation and the international location of headquarters

Profit taxes are widely acknowledged to influence the location of firms’ headquarters. This paper sheds light on the role of aspects of labor taxation for the international location of headquarters. While profit taxes can be avoided in various ways, it is much harder for firms to manipulate the firm-specific labor tax base so that labor taxes may be relatively important for firm location. We construct a unique data set of effective labor taxes in 120 countries and use data on the location of 35,206 firms to analyze the impact of labor income tax rates, the progressivity of the income tax schedule, and social security contributions on firms’ decisions where to locate their headquarters. The findings suggest that both a higher progressivity of the tax system and higher (employee- and employer-borne) social security contributions negatively influence a country’s attractiveness for headquarters location. Hence, a one percentage point increase in these payroll taxes, reduces the probability of a country to attract headquarters by 6.1 %. The results prove robust in various empirical model specifications and subsets of the data.     

Mapping tax compliance: Assemblages,distributed action and practices: A new way of doing tax research

Tax compliance denotes the act of reporting and paying taxes in accordance with the tax laws. Current social science scholarship on tax compliance can almost entirely be divided into behavioural psychology analyses and critical tax studies. This article, which presents two cases of how tax compliance is constructed, challenges the explanatory reaches of today's social science approaches, arguing that an alternative approach to understanding tax compliance is worthwhile exploring. This other choice of approach, inspired by actor–network theory (ANT), adopts a more practice-oriented focus that studies tax compliance where it takes place as well as what it is made of. Consequently, this article argues that tax compliance is a socio-material assemblage and that complying is a distributed action. The article concludes by highlighting how an ANT approach contributes to the further theoretical development of social science studies of taxation.     

Indirect Taxes on International Aviation*

There has recently been much discussion of the possible use of internationally coordinated indirect taxes, or equivalent charges, on international aviation, whether as a source of finance for development or as part of a response to heightened concerns with climate change. This paper considers the strengths and weaknesses of the leading candidate instruments of this kind. It argues that, on both policy and administration grounds, the case for increasing indirect taxes on international aviation is strong: the indirect tax burden on international aviation is very low, yet aviation contributes significantly to border-crossing environmental damage, is just as proper an object of taxation as any other commodity, and incipient tax competition is likely to result in these taxes being set at inefficiently low levels. But the form(s) in which such taxes are levied matters: a tax on aviation fuel would address the key border-crossing externalities most directly; a tax on final ticket values would have greater revenue potential, and perhaps some distributional advantage; departure/arrival taxes face the least legal obstacles, but are much blunter instruments. Optimal policy, it is shown, typically requires deploying both a fuel tax and a ticket tax, and the paper explores, both in principle and by simulation, the key considerations and trade-offs involved in designing a suitable indirect tax regime for international aviation.     

CASH FLOW OR INCOME?: The Choice of Base for Company Taxation

Cash flow and equity income (or income) are two alternativebases advocated for taxes on businesses throughout the world.Although in practice most tax systems are hybrids with elementsof both types of taxes, recent literature has stressed the meritsof the cash flow tax because it is simple in concept and itdoes not distort decisions about capital expenditures and financing.But international issues and administrative complexities—particularlytax evasion—present problems that must be sorted out beforea cash flow tax can be implemented.      

The effect of taxes on multinational debt location

We provide new evidence that differences in international tax rates and tax regimes affect multinational firms' debt location decisions. Our sample contains 8287 debt issues from 2437 firms headquartered in 23 different countries with debt-issuing subsidiaries in 59 countries. We analyze firms' marginal decisions of where to issue debt to investigate the influence of a comprehensive set of tax-related effects, including differences in personal and corporate tax rates, tax credit and exemption systems, and bi-lateral cross-country withholding taxes on interest and dividend payments. Our results show that differences in personal and corporate tax rates, the presence of dividend imputation or relief tax systems, the tax treatment of repatriated profits, and inter-country withholding taxes on dividends and interest significantly influence the decision of where to locate debt and the proportion of debt located abroad. Our results are robust to firm and issue specific factors and to the effect of legal regimes, debt market development, and exchange rate risk.     

The effectiveness and valuation of political tax minimization

We find evidence suggesting that corporate lobbying for tax purposes over the period 1999–2009 is one method by which firms managed corporate taxes. Furthermore, tax management strategies employed by these politically active firms were valued by shareholders. Firms lobbying on tax issues have lower book effective taxes and greater discretionary permanent differences in GAAP and IRS taxable income. Investors place a premium on lobbying activities for tax purposes unless the firm already has a low effective tax rate or very high book-tax differences. We conclude that lobbying political officials is one method by which firms manage risks attendant an aggressive tax strategy.     

The Effect of Taxes on the Location of Property-Casualty Insurance Firms

States levy insurance premium taxes, which are essentially gross receipt taxes on premiums. An unusual characteristic of insurance premium taxes is that in each state in which an insurance company writes premiums, the firm pays the higher of the tax rate in the state in which the company is domiciled and the state in which the policy is written. Thus, the choice of location has a significant effect on the firm's tax liability. Using firm-level data for the property-casualty (P-C) insurance industry, we calculate the firm-specific tax rate for each P-C firm for every possible state of domicile. We estimate conditional logistic models to analyze the effect of insurance premium taxes on the choice of the state of domicile of existing and relocated firms. We find robust evidence of a small, negative, and statistically significant effect of these taxes on the choice of the state of domicile.     

The capitalization of taxes in bond prices: Evidence from the market for Government of Canada bonds

This paper provides estimates of the extent to which corporate and personal income taxes are capitalized in bond prices. The methodology yields estimates of the degree of tax capitalization, rather than an implied tax rate. This makes it straightforward to identify the marginal investor and test for changes in tax capitalization. The empirical approach also makes it unnecessary to jointly estimate the degree of tax capitalization and the entire yield curve. Corporate taxes are found to have been fully capitalized in pre-tax Government of Canada bond yields during the period 1986–1993. Since 1994, taxes have not been capitalized in yields. These results are consistent with the existence of a marginal investor, but the identity of the marginal investor changed from a financial sector firm to a non-taxed entity in the early 1990s.     

Taxes, Leverage, and the Cost of Equity Capital

We examine the associations among leverage, corporate and investor level taxes, and the firm's implied cost of equity capital. Expanding on Modigliani and Miller [1958, 1963] , the cost of equity capital can be expressed as a function of leverage and corporate and investor level taxes. Based on this expression, we predict that the cost of equity is increasing in leverage, and that corporate taxes mitigate this leverage‐related risk premium, while the personal tax disadvantage of debt increases this premium. We empirically test these predictions using implied cost of equity estimates and proxies for the firm's corporate tax rate and the personal tax disadvantage of debt. Our results suggest that the equity risk premium associated with leverage is decreasing in the corporate tax benefit from debt. We find some evidence that the equity risk premium from leverage is increasing in the personal tax penalty associated with debt.     

The welfare comparison of corrective ad valorem and unit taxes under monopolistic competition

The ad valorem versus unit tax debate has traditionally emphasized tax yield. On this criterion, ad valorem taxes outperform unit taxes in terms of welfare for a wide range of imperfect competition settings including Dixit–Stiglitz monopolistic competition. However, in a number of policy fields such as environmental, health, and trade economics, policy makers use taxes to reduce the production/consumption volume in an industry, i.e., to correct an externality rather than to improve tax yield. This paper compares the two tax instruments with respect to equal corrective effect in a Dixit–Stiglitz setting with love of variety, entry, exit, and redistribution of tax revenues. We find that unit taxes lead to more firms in the industry, less output per firm, less tax revenue, but higher welfare compared to ad valorem taxes.      

Why Capital Income Taxes Survive in Open Economies: The Role of Multinational Firms

This paper discusses the role of multinational firms and double taxation treaties for corporate income taxation in open economies. We show that it is optimal for a small open economy to levy positive corporate income taxes if multinational firms are taxed according to the full taxation after deduction system or the foreign tax credit system. Positive corporate taxes also occur in the asymmetric case where some countries apply the exemption system and others apply the tax credit system. If all countries apply the exemption system, the optimal corporate income tax is zero. We also show that, under tax competition, corporate income taxes are not necessarily too low from the perspective of the economy as a whole. While the undertaxation result is confirmed for the case of the exemption system, tax rates may also be inefficiently high if the deduction or the credit systems are applied.     

The classical tax system,imputation tax and capital budgeting

Differences in the taxation systems in Britain, France, and some other European countries (which use the imputation system) compared with the USA and the Netherlands, among others (which use the classical tax system), mean that the cost of equity capital should be specified, using a capital asset pricing model methodology, in different ways. Under the imputation system its value should be net of personal taxes; under the classical tax system, it should be gross of personal taxes. Similarly the value of the tax shield on debt for input into adjusted present value calculations differs, being significantly greater under the classical tax system. Formulae are set out to enable the calculation of the magnitude of the tax shield readily to be undertaken.     

对提升直接税比重 均衡税制结构的思考

提高直接税比重是税制改革所需迫切解决的重要议题,从而实现税种配置上的大致均衡。但是,由于征管手段等原因,至今未取得实质性突破。构建直接税体系,更符合税负公平和量能纳税为原则的现代税法核心,因此逐步提高直接税比重,并扬长避短,发挥直接税和间接税的各自优势。
