How Big Are the Tax Benefits of Debt?

I integrate under firm-specific benefit functions to estimate that the capitalized tax benefit of debt equals 9.7 percent of firm value (or as low as 4.3 percent, net of personal taxes). The typical firm could double tax benefits by issuing debt until the marginal tax benefit begins to decline. I infer how aggressively a firm uses debt by observing the shape of its tax benefit function. Paradoxically, large, liquid, profitable firms with low expected distress costs use debt conservatively. Product market factors, growth options, low asset collateral, and planning for future expenditures lead to conservative debt usage. Conservative debt policy is persistent.     

The Effect of Interest Rates on the Value of Corporate Assets and the Risk Premia of Corporate Debt

A growing number of papers have applied option pricing techniques to the valuation of risky debt. This paper deals directly with how a firm's relationship to interest rates affects its debt. A sequential binomial model is used to price the zero-coupon bonds of a firm whose value is related to interest rate changes.The results show that the strength of the relationship between firm value and interest rates (interest-rate risk) can have a significant impact on the value of a firm's debt. The model produces its most powerful results when the volatility of firm value is high and the term structure has a steep (negative or positive) slope; there is no impact when the term structure is flat. Our results indicate that empirical studies of yield spreads may have severe shortcomings if the relationship of firm value to interest rate changes is ignored.     

Financial effects of an uncertain change in VAT rates in the EU

The paper analyses how close relationships to banks influence a firm’s choice of financing its debt through publicly marketed bonds or bank loans. It is shown that large Japanese firms use less bank debt, if banks own shares in the firm or bank employees are members of the firm’s board. This result supports a theoretical framework, where banks are able to control agency problems associated with debt. Firms use bank loans in order to be monitored, which enables them to access cheaper bond finance. Closer bank–firm relationships facilitate monitoring for the bank and reduce therefore the need for bank finance.     

A two-part fractional regression model for the financial leverage decisions of micro,small, medium and large firms

In this paper we examine the following two hypotheses, which traditional theories of capital structure are relatively silent about: (i) the determinants of financial leverage decisions are different for micro, small, medium and large firms; and (ii) the factors that determine whether or not a firm issues debt are different from those that determine how much debt it issues. Using a binary choice model to explain the probability of a firm raising debt and a fractional regression model to explain the relative amount of debt issued, we find strong support for both hypotheses. Confirming recent empirical evidence, we find also that, although larger firms are more likely to use debt, conditional on their having some debt, firm size is negatively related to the proportion of debt used by firms.     

Debt contracts in the presence of performance manipulation

Empirical evidence suggests that firms often manipulate reported numbers to avoid debt covenant violations. We study how a firm’s ability to manipulate reports affects the terms of its debt contracts and the resulting investment and manipulation decisions that the firm implements. Our model generates novel empirical predictions regarding the use and the level of debt covenant, the interest rate, the efficiency of investment decisions, and the likelihood of covenant violations. For example, the model predicts that the optimal debt contract for firms with relatively strong (weak) corporate governance (i.e., cost of manipulation) induces overinvestment (underinvestment). Moreover, for firms with strong (weak) corporate governance, an increase in corporate governance quality leads to tighter (looser) covenant, more (less) frequent covenant violations and lower (higher) interest rate. Our model highlights that the interest rate, which is a common proxy for the cost of debt, neither accounts for the distortion of investment efficiency nor the expected manipulation costs arising under debt financing. We propose a measure of cost of debt capital that accounts for these effects.     

A Dynamic Model of Optimal Capital Structure

This paper presents a continuous time model of a firm that candynamically adjust both its capital structure and its investmentchoices. In the model we endogenize the investment choice aswell as firm value, which are both determined by an exogenousprice process that describes the firm's product market. Withinthe context of this model we explore cross-sectional as wellas time-series variation in debt ratios. We pay particular attentionto interactions between financial distress costs and debtholder/equityholderagency problems and examine how the ability to dynamically adjustthe debt ratio affects the deviation of actual debt ratios fromtheir targets. Regressions estimated on simulated data generatedby our model are roughly consistent with actual regressionsestimated in the empirical literature.     

Rollover risk and credit risk under time-varying margin

For a firm financed by a mixture of collateralized (short-term) debt and uncollateralized (long-term) debt, we show that fluctuations in margin requirements, reflecting funding liquidity shocks, lead to increasing the firm’s default risk and credit spreads. The severity with which a firm is hit by increasing margin requirements highly depends on both its financing structure and debt maturity structure. Our results imply that an additional premium should be added when evaluating debt in order to account for rollover risks, especially for short-matured bonds. In terms of policy implications, our results strongly indicate that regulators should intervene fast to curtail margins in crisis periods and maintain a reasonably low margin level in order to effectively prevent creditors’ run on debt.     

On financial contracting: An analysis of bond covenants

With risky debt outstanding, stockholder actions aimed at maximizing the value of their equity claim can result in a reduction in the value of both the firm and its outstanding bonds. We examine ways in which debt contracts are written to control the conflict between bondholders and stockholders. We find that extensive direct restrictions on production/investment policy would be expensive to employ and are not observed. However, dividend and financing policy restrictions are written to give stockholders incentives to follow a firm-value-maximizing production/investment policy. Taking into account how contracts control the bondholder- stockholder conflict leads to a number of testable propositions about the specific form of the debt contract that a firm will choose.     

Corporate taxes,capital structure,and valuation: Combining Modigliani/Miller and Miles/Ezzell

The valuation of a firm with discounted cash flow (DCF) approaches requires assumptions about the firm’s financing strategy. The approaches of Modigliani and Miller and Miles and Ezzell assume that either a passive debt management with predetermined debt levels or active debt management with capital structure targets is applied. Over the last decades, various extensions of these approaches have been developed to allow for a more realistic depiction of financial decision making. However, recent empirical analyses indicate that current theories still have limited power to explain large variances in capital structure across time. We provide an alternative explanation for the empirical observation by assuming that firms combine both capital structure targets and predetermined debt within future periods, and we show how to value a firm given such a partially active debt management. The approaches of Modigliani and Miller and Miles and Ezzell are embedded into a common valuation framework, with the familiar valuation formulas shown as special cases. In a simulation analysis, we illustrate that the textbook valuation formulas may produce considerable valuation errors if a firm applies a partially active debt management.     

Taxes, Financing Decisions, and Firm Value

We use cross-sectional regressions to study how a firm's value is related to dividends and debt. With a good control for profitability, the regressions can measure how the taxation of dividends and debt affects firm value. Simple tax hypotheses say that value is negatively related to dividends and positively related to debt. We find the opposite. We infer that dividends and debt convey information about profitability (expected net cash flows) missed by a wide range of control variables. This information about profitability obscures any tax effects of financing decisions.     

On debt service and renegotiation when debt-holders are more strategic

The contingent claims analysis of firm financing often presents a debt renegotiation game with a passive bank that does not use its ability to force liquidation strategically, contrary to what is observed in practice. We consider two motives that may lead a bank to refuse to renegotiate: maintaining its reputation to preserve its future lending activity and deterring firms from overstating their debt service abatement when they renegotiate. We show that with public information and private debt only, the optimal probability of debt renegotiation is high when the firm’s anticipated liquidation value is high. Under asymmetric information about liquidation value, the high liquidation value firm may be tempted to mimic the low liquidation value firm to reduce its debt service. To deter such mimicking, banks may sometimes refuse to renegotiate with firms having a low liquidation value.     

Real options,agency conflicts,and optimal capital structure

We examine the impact of a stockholder–bondholder conflict over the timing of the exercise of an investment option on firm value and corporate financial policy. We find that an equity-maximizing firm exercises the option too early relative to a value-maximizing strategy, and we show how this problem can be characterized as one of overinvestment in risky investment projects. Equityholders’ incentive to overinvest significantly decreases firm value and optimal leverage, and significantly increases the credit spread of risky debt. Numerical solutions illustrate how the agency cost of overinvestment and its effect on corporate financial policy vary with firm and project characteristics.     

Banks as lenders and shareholders: Evidence from Japan

This paper examines the effects of the main bank's equity–debt structure, (i.e., equity stakes and debt claims) on firm performance and financial policies in Japan over the period 1977–1987. Results show that firms with main bank equity stakes have lower performance than those without. However, among firms with main bank equity stakes, the equity–debt structure of claims has a positive effect on firm performance. The positive effect of the main bank's equity–debt structure is found to be greater in group-affiliated firms than in independent firms. The main bank maximizes its own interests by charging a higher interest rate when its equity stakes are relatively less than its debt claims and by prompting firms to pay more dividends when its equity stakes are relatively high.     

Partial adjustment toward target capital structures

The empirical literature provides conflicting assessments about how firms choose their capital structures. Distinguishing among the three main hypotheses (“tradeoff”, pecking order, and market timing) requires that we know whether firms have long-run leverage targets and (if so) how quickly they adjust toward them. Yet many previous researchers have applied empirical specifications that fail to recognize the potential for incomplete adjustment. A more general, partial-adjustment model of firm leverage indicates that firms do have target capital structures. The typical firm closes about one-third of the gap between its actual and its target debt ratios each year.     

Risky debt,jump processes,and safety covenants

The usual assumptions in the continuous-time contingent claims pricing of risky debt are (1) the firm is in default only when the value of its remaining assets falls short of the currently due promised payment and (2) the firm value follows continuous diffusion-process dynamics. It is the joint relaxation of these two simplifying assumptions that motivate this paper in its study of the valuation of risky debt and safety covenants when the firm value follows (possibly) discontinuous sample paths. Explicit solutions are derived and compared to the work of Black and Cox (1976).     

Aligning debt and equity claimant interests: Evidence from dual claim investors

This study investigates how investors that own both equity and debt in the same firm affect other shareholders in the firm. It documents that dual claim investors are quite prevalent among the industrial firms listed in the Russell 3000, with over 20% of them having a bank holding company that owns both debt and equity in the firm. The results imply that shareholders are substantially impacted by the presence of dual claim investors in firms, suggesting that relatively small ownership stakes by dual claim banks are associated with greater conflicts of interest among shareholders and debt holders; while relatively large bank equity stakes may benefit outside shareholders when aligned with loan by dual claim banks because they improve bank monitoring incentives and reduce the agency cost of debt.     

Capital Structure Swaps and Shareholder Wealth

We show how capital structure swaps can increase the wealth of a firm's long‐term shareholders when a firm's debt or equity is misvalued. We review the conventional rule that a firm should issue equity and use the proceeds to retire outstanding debt (an equity‐for‐debt swap) when equity is overvalued, or repurchase equity with proceeds of new debt (a debt‐for‐equity swap) when equity is undervalued. We also analyse the more complex case where a firm's debt and equity are both undervalued, showing the optimal swap may be to issue undervalued equity, contrary to the conventional rule.     

Credit risk analysis with creditor’s option to extend maturities

We present a Merton (J Finance, 1974)-type structural model of credit risk in which the borrower firm refinances its debt, there is cost for bankruptcy, and the creditor has an option to extend the date of maturity of debt if the firm defaults. We show that a solution exists in such a model and in that solution the creditor has incentive to extend maturity to avoid bankruptcy cost. We solve the model numerically and argue that such maturity extension option for the creditor can have substantial impact on the debt and stock values of the firm.     

CEO's Inside Debt and Dynamics of Capital Structure

Debt‐type compensation (inside debt) exacerbates the divergence in risk preferences between the chief executive officer (CEO) and shareholders and, in turn, affects capital structure decisions. An excessively risk‐averse CEO tends to use less debt than the shareholders desire, reduce debt quickly when the firm is overlevered, but is reluctant to increase debt when the firm is underlevered. We find that higher CEO's inside debt ratio (i.e., inside debt as a percentage of total incentive compensation) is associated with lower firm leverage and faster (slower) leverage adjustments toward the shareholders’ desired level for overlevered (underlevered) firms. The CEO's inside debt ratio most conducive to capital structure rebalancing is around 10% of the firm's market debt ratio.     

Default Risk, Asset Pricing, and Debt Control

The pricing and control of firms’ debt has become a majorissue since Merton’s (1974) seminal article. Yet Mertonas well as other recent theories presume that the asset valueof the firm is independent of the debt of the firm. However,when using debt finance, firms may have to pay a premium foran idiosyncratic default risk and may face debt constraints.We demonstrate that firm-specific debt constraints and endogenousrisk premia, based on collateralized borrowing, affect the assetvalue of the firm and, in turn, the collateral value of thefirm. In order to explore the interdependence of debt financeand asset pricing of firms, we endogenize default premia andborrowing constraints in a production-based asset pricing model.In this context then the dynamic decision problem of maximizingthe present value of the firm faces an additional constraintgiving rise to the debt-dependent firm value. We solve for theasset value of the firm with debt finance by the use of numericaldynamic programming. This allows us to solve the debt controlproblem and to compute sustainable debt as well as the firm’sdebt value.
