The downside of formula apportionment: evidence on factor demand distortions

This paper investigates the impact of corporate taxes on the input factor choice of multi-jurisdictional entities (MJEs) under a formula apportionment (FA) regime. Our testing ground is the German local business tax that applies FA regulations with income apportionment according to the relative payroll share. Using unique data on the population of German firms, we find that MJEs distort their employment and payroll costs in favor of low-tax locations. On average, a 1-percentage-point-increase in the tax rate differential between an affiliate and foreign group members is found to lower the affiliate’s payroll to capital ratio by 1.9%.     

How Big is the Tax Advantage to Debt?

This paper uses an option valuation model of the firm to answer the question, “What magnitude tax advantage to debt is consistent with the range of observed corporate debt ratios?” We incorporate into the model differential personal tax rates on capital gains and ordinary income. We conclude that variations in the magnitude of bankruptcy costs across firms can not by itself account for the simultaneous existence of levered and unlevered firms. When it is possible for the value of the underlying assets to jump discretely to zero, differences across firms in the probability of this jump can account for the simultaneous existence of levered and unlevered firms. Moreover, if the tax advantage to debt is small, the annual rate of return advantage offered by optimal leverage may be so small as to make the firm indifferent about debt policy over a wide range of debt-to-firm value ratios.     

The Determinants of Debt Maturity Structure: Evidence from France,Germany and the UK

We examine the determinants of the debt maturity structure of French, German and British firms. These countries represent different financial and legal traditions that may have implications on corporate debt maturity structure. Our model incorporates the factors representing three major theories (tax considerations, liquidity and signalling, and contracting costs) of debt maturity. It also controls for capital market conditions. The results confirm the applicability of most theories of debt maturity structure for the UK firms. However, the evidence from France and Germany are mixed. Overall the findings suggest that the debt maturity structure of a firm is determined by firm‐specific factors and the country's financial systems and institutional traditions in which it operates.     

Debt,Agency Costs,and Industry Equilibrium

We show that risk characteristics of projects' cash flows are endogenously determined by the investment decisions of all firms in an industry. As a result, in reasonable settings, financial structures which create incentives to expropriate debtholders by increasing risk are shown not to reduce value in an industry equilibrium. Without taxes, capital structure is irrelevant for individual firms despite its effect on the equityholders' incentives, but the maximum total amount of debt in the industry is determinate. Allowing for a corporate tax advantage of debt, capital structure becomes relevant but firms are indifferent between distinct alternative debt levels.     

Restricted interest deductibility and multinationals’ use of internal debt finance

This paper reconsiders the role of interest deductibility for internal debt financing of multinational corporations (MNCs). We provide quasi-experimental evidence using restrictions on interest deductibility through thin-capitalization rules. Explicitly distinguishing between firms subject to a binding restriction and unrestricted firms, a panel data sample selection model is used to explore the tax sensitivity of the capital structure of foreign subsidiaries of MNCs. Our results confirm that the tax incentive for using internal loans is effectively removed for restricted subsidiaries. While internal debt financing of unrestricted subsidiaries positively responds to taxes, the effects are relatively small.     

Optimal capital structure under corporate and personal taxation

In this paper, a model of corporate leverage choice is formulated in which corporate and differential personal taxes exist and supply side adjustments by firms enter into the determination of equilibrium relative prices of debt and equity. The presence of corporate tax shield substitutes for debt such as accounting depreciation, depletion allowances, and investment tax credits is shown to imply a market equilibrium in which each firm has a unique interior optimum leverage decision (with or without leverage-related costs). The optimal leverage model yields a number of interesting predictions regarding cross-sectional and time-series properties of firms' capital structures. Extant evidence bearing on these predictions is examined.     

The Capital Structure of Large Firms and the Use of Dutch Financing Entities

Large firms may issue debt securities to obtain external financing or set up lowly‐taxed affiliates for internal debt‐shifting purposes. In addition, they may channel interest payments through Dutch special purpose entities (SPEs) to avoid withholding taxes, a widely‐used arbitrage strategy. Analysing the capital structure of large EU‐based multinationals, this paper provides evidence that the use of Dutch‐issuing SPEs is associated with higher debt financing relative to equity. Furthermore, it shows that EU subsidiaries of larger firms are more leveraged and that the use of Dutch on‐lending SPEs is also associated with higher subsidiary leverage. Thus, the paper provides evidence that Dutch SPEs facilitate higher external debt financing as well as internal debt shifting. The findings indicate that withholding taxes on interest payments to entities outside the EU, determined by individual EU member states, are not very effective. The national tax systems of EU countries such as the Netherlands, which does not impose interest withholding tax, allow large firms to avoid those taxes.     

Capital structure and international debt shifting

This paper presents a model of a multinational firm's optimal debt policy that incorporates international taxation factors. The model yields the prediction that a multinational firm's indebtedness in a country depends on a weighted average of national tax rates and differences between national and foreign tax rates. These differences matter as multinationals have an incentive to shift debt to high-tax countries. The predictions of the model are tested using a novel firm-level dataset for European multinationals and their subsidiaries, combined with newly collected data on the international tax treatment of dividend and interest streams. Our empirical results show that a foreign subsidiary's capital structure reflects local corporate tax rates as well as tax rate differences vis-à-vis the parent firm and other foreign subsidiaries, although the overall economic effect of taxes on leverage appears to be small. Ignoring the international debt shifting arising from differences in national tax rates would understate the impact of national taxes on debt policies by about 25%.     

Control considerations,creditor monitoring,and the capital structure of family firms

In this paper, I analyze the motives moving founders and their families to influence the capital structure decision. For this, I complement detailed corporate governance information for Germany with data from other countries. The results for the German bank-based financial system contradict prior findings for other institutional environments. According to these results, family firms in Germany rely less heavily on debt than non-family firms. Less surprisingly, the opposite holds true for the international dataset. Different empirical tests indicate that this puzzling result can be explained by control considerations. Founders and their families use the capital structure to optimize their control over the firm. However, whether family firms rely more or less on debt depends on the level of creditor monitoring in an institutional environment. These findings emphasize that control considerations of major shareholders are important—although often overlooked—determinants of the capital structure.     

Personal taxation of capital income and the financial leverage of firms

Tax competition for capital has led to a trend where many countries levy lower taxes on interest income, often introducing differential taxation between interest and business income. This study analyzes the effect on firm debt usage. We exploit Germany’s 2009 tax reform, which introduced a final withholding tax on interest income with a flat rate 18 percentage points below the unchanged tax rate on income from unincorporated businesses, as a quasi-experiment. The results, based on firm-level panel data, indicate that firms increase their leverage when the tax rate on interest income decreases, albeit to a small degree.     

The Effect of Taxes on Corporate Financing Decisions: Evidence from a Panel of Italian Firms

This paper provides additional evidence on the relationship between corporate taxes and debt using panel data on Italian companies. The panel covers 1054 companies for the years 1982–1994.The paper follows the Graham-Shevlin methodology for calculating company specific marginal tax rates (MTR) relying on the non-linearity of corporate tax schedules resulting from company losses and the ensuing tax provisions (carry-forward and backward rules). In the period covered by the panel there were in Italy two taxes on corporate income (IRPEG and ILOR), with different loss carry-forward rules, whose statutory tax rates and tax bases changed several times. For these reasons the simulated MTRs display both cross-sectional and time-series variation.The paper tests whether taxes encourage the use of debt by analysing incremental financing decisions. In order to cope with the endogeneity of the MTR the paper considers two different specifications. The first uses the lagged value of the simulated MTR. The second employs the estimate of before-financing MTR proposed by Graham et al. (1998). Significant cross-sectional tax effects are identified under both specifications whereas time-series variation cannot be identified if due account is taken of firm-fixed tax effects.The paper also investigates whether personal taxes affect corporate financing decisions. The MTR may either overstate or understate the fiscal benefit of debt financing according to whether, at the personal level, interest income is taxed at a rate that is higher or lower than the tax rate on returns from common stocks. Differences in the dividend-payout ratio across companies and several reforms in interest, dividend and capital gains taxation provide sufficient cross-section and time-series variations to identify the effect of personal taxes on debt usage.     

The tax-efficient use of debt in multinational corporations

Affiliates of multinationals borrow a considerable amount from their parent company, even when the parent is located in a high-tax country. This is at odds with standard theories of a tax-efficient capital structure. We set up a model that analyzes the functioning of the internal capital market and investigates the trade-off between tax savings and capital market frictions within the group. We test the model on data of the universe of German multinationals. The empirical analysis largely supports our model in that: (i) smaller multinationals often rely on parental debt financing; (ii) larger multinationals are more likely to use internal banks; (iii) parental debt and external debt are substitutes and the mix depends on the relative cost of raising capital through the parent and the affiliates; (iv) local and within-group tax incentives play an important role in determining all three types of debt.     

Capital structure policies in Europe: Survey evidence

In this paper we present the results of an international survey among 313 CFOs on capital structure choice. We document several interesting insights on how theoretical concepts are being applied by professionals in the UK, the Netherlands, Germany, and France and we directly compare our results with previous findings from the US our results emphasize the presence of pecking-order behavior. At the same time this behavior is not driven by asymmetric information considerations. The static trade-off theory is confirmed by the importance of a target debt ratio in general, but also specifically by tax effects and bankruptcy costs. Overall, we find remarkably low disparities across countries, despite the presence of significant institutional differences. We find that private firms differ in many respects from publicly listed firms, e.g. listed firms use their stock price for the timing of new issues. Finally, we do not find substantial evidence that agency problems are important in capital structure choice.     

Do corporate tax cuts increase investments?

This paper studies the effect of corporate taxes on investment. Since firms with a foreign parent have more cross-country profit shifting opportunities than domestically owned firms do, their effective tax rate and, consequently, their tax-induced costs to investment are lower. We therefore expect capital investment responses to a corporate tax cut to be heterogeneous across firms. Using firm-level data on German corporations, we exploit the 2008 tax reform, which substantially cut corporate taxes as an exogenous policy shock and expect domestically owned firms' investments to be more responsive to the reform. We show exactly this in a difference-in-differences setting. We find that the reduction in corporate tax payments led to a one-to-one increase in the real investments of domestic firms. The effect is stronger for domestic firms relying more on internal funds. Correspondingly, labor investment increased more for domestic firms, ensuring a constant mix of input factors. In addition, we show that domestic firms' sales grew faster after the tax cut than the sales of foreign-owned firms. Our results imply that corporate tax changes can increase corporate investment but that domestic firms benefit more than foreign-owned firms from a tax cut through higher investment responses resulting in greater sales growth.     

Leverage and Taxes: Evidence from the Real Estate Industry

Finance theory has long viewed corporate income taxes as a potentially important determinant of corporate financing decisions and capital structures. But finance academics have been unable to provide convincing empirical evidence of a material effect of taxes on corporate leverage, in part because of difficulties in constructing an effective proxy for marginal corporate tax rates, and hence for the tax benefits of debt, for large samples of individual companies. The authors address this by analyzing leverage decisions in an industry whose publicly traded entities are organized either as taxable corporations, or as real estate investment trusts (REITs) that effectively avoid entity level taxation. This enables them to measure the relative tax benefits of debt with greater precision while controlling for important nontax characteristics that affect debt usage. The tax hypothesis predicts that for real estate firms with similar asset portfolios, taxable firms should have more debt than their nontaxable counterparts. Both the nontaxable and the taxable real estate firms in our sample routinely have more than twice the leverage of industrial firms, which suggests that factors other than taxes are contributing to their use of debt. But among real estate firms, tax status appears to play a much weaker role. Taxable firms have significantly more leverage only after 2000, when restrictions on REITs were removed through new regulations that made their operations much more like those of taxable real estate firms. Our findings also depend on real estate characteristics—most notably, only residential real estate firms demonstrated differences that are consistent with the tax hypothesis. Taken together, the authors’ findings suggest that although taxes do seem to matter, their role is clearly secondary relative to factors such as the nature of the firm’s assets. A generous interpretation of our evidence puts the effect of taxes between one‐third and one‐half of that implied by prior research.     

A Multinational Perspective on Capital Structure Choice and Internal Capital Markets

This paper analyzes the capital structures of foreign affiliates and internal capital markets of multinational corporations. Ten percent higher local tax rates are associated with 2.8% higher debt/asset ratios, with internal borrowing being particularly sensitive to taxes. Multinational affiliates are financed with less external debt in countries with underdeveloped capital markets or weak creditor rights, reflecting significantly higher local borrowing costs. Instrumental variable analysis indicates that greater borrowing from parent companies substitutes for three‐quarters of reduced external borrowing induced by capital market conditions. Multinational firms appear to employ internal capital markets opportunistically to overcome imperfections in external capital markets.     

Dividend taxation and the ownership structure of private firms

This paper examines the effect of dividend taxation on the ownership structure of private firms. I exploit a German dividend tax increase that only affects corporate shareholders owning a minority stake. Using data on private German firms and their shareholders, I find that corporate shareholders reduce their minority stakes in firms after the dividend tax reform. This result is in line with the notion that, because minority shareholders do not have sufficient decision-making power to influence the payout policy, they can only react to a dividend tax increase by selling their shares. This effect is larger when the affected minority shareholders face high dividend tax costs. However, I find a smaller effect when the benefits of the minority stakes are highly relevant for the firm and the affected shareholders, suggesting that non-tax factors mute the response to dividend taxes. In addition, I find that the largest shareholder of the firm buys the minority stake, resulting in greater ownership concentration. These findings extend the prior literature that finds no effect of dividend taxes on the ownership structure of private firms.     

Corporate tax aggression and debt

We provide a tradeoff model of the capital structure that allows leverage to be a function of a firm’s choice of tax aggressiveness. The model’s testable implications are supported empirically. Debt use is inversely related to corporate tax aggression for most firms, and the relation is economically important. This substitution effect is especially evident for firms exhibiting high tax-shelter prediction scores. The effect attenuates for benign forms of tax avoidance and during the recent credit crisis period. For the most profitable firms, debt and tax aggression are complements. Our results extend the empirical findings of Graham and Tucker (2006).     

Optimal Capital Structure and Industry Dynamics

This paper provides a competitive equilibrium model of capital structure and industry dynamics. In the model, firms make financing, investment, entry, and exit decisions subject to idiosyncratic technology shocks. The capital structure choice reflects the tradeoff between the tax benefits of debt and the associated bankruptcy and agency costs. The interaction between financing and production decisions influences the stationary distribution of firms and their survival probabilities. The analysis demonstrates that the equilibrium output price has an important feedback effect. This effect has a number of testable implications. For example, high growth industries have relatively lower leverage and turnover rates.     

Debt and taxes: Evidence from the real estate industry

Compelling empirical evidence documenting a material effect of corporate taxes on leverage decisions is limited, in part because of difficulties in constructing an effective proxy for the firm's tax benefit of debt. We examine leverage decisions across taxable and nontaxable real estate firms—firms for which we can measure the relative tax benefit of debt with little error. The tax hypothesis implies that for firms with similar asset portfolios, taxable firms should have more debt than their nontaxable counterparts. Consistent with this, leverage ratios of taxable real estate firms are higher than their nontaxable counterparts, but the magnitude of this difference is at most one-half of that implied by studies that employ simulated marginal tax rates.
