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.     

Measuring the Agency Cost of Debt

We adapt a contingent claims model of the firm to reflect the incentive effects of the capital structure and thereby to measure the agency costs of debt. An underlying model of the firm and the stochastic features of its product market are analyzed and an optimal operating policy is chosen. We identify the change in operating policy created by leverage and value this change. The model determines the value of the firm and its associated liabilities incorporating the agency consequences of debt.     

Implications of Debt Renegotiation for Optimal Bank Policy and Firm Behavior

This paper analyzes the problems associated with the renegotiation of debt contracts involving a bank (the lender) and a firm (the borrower) when the latter is operated by a risk averse manager. Firms undertake risky projects with loan capital borrowed from the bank. When a firm cannot pay off a loan it is technically bankrupt. Both the borrower and the lender may however experience a Pareto-improvement in their positions by renegotiating the loan. By renegotiating the terms of the debt the financially distressed firm can avoid the stigmatization of bankruptcy and the bank can avoid the costs of seizing the borrower's assets. However, our main finding is that, from the bank's point of view, renegotiating as a policy of recovering loan payments may be inefficient in practice because of false bankruptcy claims and moral hazard problems associated with exposure of the borrowing firm to the risk of default. We present a solution to the false bankruptcy claim problem that involves a mixe d strategy between asset seizure by the bank and debt renegotiation.     

The Cost of Debt

We use exogenous variation in tax benefit functions to estimate firm‐specific cost of debt functions that are conditional on company characteristics such as collateral, size, and book‐to‐market. By integrating the area between the benefit and cost functions, we estimate that the equilibrium net benefit of debt is 3.5% of asset value, resulting from an estimated gross benefit (cost) of debt equal to 10.4% (6.9%) of asset value. We find that the cost of being overlevered is asymmetrically higher than the cost of being underlevered and that expected default costs constitute only half of the total ex ante costs of debt.     

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.     

Employee well-being,firm leverage,and bankruptcy risk

Employees of liquidating firms are likely to lose income and non-pecuniary benefits of working for the firm, which makes bankruptcy costly for employees. This paper examines whether firms take these costs into account when deciding on the optimal amount of leverage. We find that firms with leading track records in employee well-being significantly reduce the probability of bankruptcy by operating with lower debt ratios. Moreover, we observe that firms with better employee track records have better credit ratings, even when we control for differences in firm leverage.     

On the Interaction of Real and Financial Decisions of the Firm Under Uncertainty

This study analyzes the interaction between the optimal level of investment and debt financing. For this purpose, a model is structured in which a firm, facing an uncertain price, has to decide on its optimal level of investment and debt. The amount of investment sets a limit on output whose optimal level is determined after price is realized. The debt involved is risky (there exists a possibility of bankruptcy). The analysis proves that investment and its optimal financing have to be simultaneously determined and that a negative relationship exists between operating and financial leverage. We also demonstrate that as the tax rate increases, optimal capacity decreases and optimal leverage increases. An analysis of the impact of changes in the expected price shows that under some conditions, an increase in expected price would lead to an increase in optimal investment (firm size) and a decrease in optimal debt.     

Debt and managerial rents in a real-options model of the firm

We present a theory of capital investment and debt and equity financing in a real-options model of a public corporation. The theory assumes that managers maximize the present value of their future compensation (managerial rents), subject to constraints imposed by outside shareholders’ property rights to the firm's assets. Absent bankruptcy costs, managers follow an optimal debt policy that generates efficient investment and disinvestment. We show how bankruptcy costs can distort both investment and disinvestment. We also show how managers’ personal wealth constraints can lead to delayed investment and increased reliance on debt financing. Changes in cash flow can cause changes in investment by tightening or loosening the wealth constraints. Firms with weaker investor protection adopt higher debt levels.     

Corporate Debt Value,Bond Covenants,and Optimal Capital Structure

This article examines corporate debt values and capital structure in a unified analytical framework. It derives closed-form results for the value of long-term risky debt and yield spreads, and for optimal capital structure, when firm asset value follows a diffusion process with constant volatility. Debt values and optimal leverage are explicitly linked to firm risk, taxes, bankruptcy costs, risk-free interest rates, payout rates, and bond covenants. The results elucidate the different behavior of junk bonds versus investment-grade bonds, and aspects of asset substitution, debt repurchase, and debt renegotiation.     

减税政策对小微企业债务期限结构的影响

本文主要探讨减税政策对小微企业债务期限结构的影响。理论上,减税政策对企业债务期限结构产生两种方向相反的效果:一是减税后企业盈利状况改善,激励银行通过延长债务期限以争取企业客户;二是减税后企业可支配现金流增加,加剧银行与企业间的委托代理问题,促使银行缩短债务期限以便加强企业监督。本文以所得税减半征收政策作为自然实验,基于全国税收调查数据库(2010-2015)考察了减税政策对小微企业债务期限结构的影响。实证结果显示:减税后企业的债务期限整体得以延长;如果减税后企业的盈利状况改善更多,或可支配现金流增长更缓,企业债务期限延长幅度更大。此外,本文发现在快速扩张行业、有产能过剩风险行业以及房地产上下游关联行业中的企业往往会因为较强的代理成本效应而面临减税后债务期限的边际缩短。本文研究结论对改善企业融资结构,特别对提高小微企业获取中长期贷款能力,有一定的参考意义。     

Determinants of Bank Debt in a Continental Financial System: Evidence from Spanish Companies

We test hypotheses about the structure of corporate debt ownership and the use of bank debt by firms in a civil‐law country, Spain. We focus on bank debt effects in the presence of information asymmetries and agency costs, and on efficient versus inefficient firm liquidation. We find that the relation between growth opportunities and bank financing is not as strong as the one found in common‐law countries, that there is a positive relation between firm size and the proportion of bank debt used, and that firms closer to bankruptcy and highly leveraged are more likely to use bank debt.     

Corporate liquidity and dividend policy under uncertainty

We examine optimal liquidity (retained earnings) and dividend choice incorporating debt financing with risk of default and bankruptcy costs as well as growth options under revenue uncertainty. We revisit the conditions for dividend policy irrelevancy and the broader role of retained earnings and dividends. Retained earnings have a net positive impact on firm value in the presence of growth options, high external financing costs and low default risk. High levels of retained earnings enhance debt capacity but have a negative effect on equity value due to the likelihood of losing accumulated cash balances in case of default, unless offset by high external financing costs. Opposite directional effects of retained earnings on equity and debt create a U-shaped relation with firm value. The framework is extended to analyze management-shareholder conflicts, demonstrating that managers accumulate higher than optimal cash.

Valuation of the Debt Tax Shield

In this study, we use cross–sectional regressions to estimate the value of the debt tax shield. Recognizing that debt is correlated with the value of operations along nontax dimensions, we estimate reverse regressions in which we regress future profitability on firm value and debt rather than regressing firm value on debt and profitability. Reversing the regressions mitigates bias and facilitates the use of market information to control for differences in risk and expected growth. Our estimated value for the debt tax shield is approximately 40 percent (10 percent) of debt balances (firm value), net of the personal tax disadvantage of debt.     

The Bankruptcy Decision and Debt Contract Renegotiations

We consider the bankruptcy law and workout practices in theUnited States and model bankruptcy as a strategic decision.We analyze a firm's choice between liquidation under Chapter7, renegotiation of the debt contract in a workout, and reorganizationunder Chapter 11 of the bankruptcy code. Our premise is thata financially distressed firm chooses its action in order tominimize the loss in value caused by the well-known over- andunder-investment problems. We show that the firm initiates aworkout when it faces under-investment, and commences Chapter11 when it faces over-investment. Some of the results are: (i)in default, total firm value and equity value increase uponthe announcement of a workout and decrease upon the announcementof Chapter 11; (ii) firms with shorter maturity of debt aremore likely to reorganize in a workout; (iii) among the firmsthat renegotiate their debt contract, the proportion of firmsentering Chapter 11 is higher for firms in mature industriesthan for firms in growth industries.     

Optimal capital structure: A multi-period programming model for use in financial planning

This paper describes a multi-period, chance constrained mathematical programming model to compute for each period, the firm's optimal debt to equity ratio and the optimal maturity distribution of its debt. The model assumes that the firm's objective is to maximize total value of the firm, and that the firm operates in a world of uncertainty, with corporate income taxes and bankruptcy costs. Finally, the actual coupon rate paid by the firm which is commensurate to the risk of default is endogenously determined by the model.     

Debt overhang and non-distressed debt restructuring

In this paper, we analyse the restructuring of debt in the presence of debt overhang. The firm starts out with a debt liability and an investment opportunity. Then with unrestructured debt, the firm maintains the current borrowing payments until default or investment. If the creditors allow the parties to restructure the debt with exchange offers, then the borrowing payments change as well as the default and investment points. We find that there is a unique optimal restructuring path which maintains debt at positive levels but defers default indefinitely. This path is optimal regardless of whether the debt holders or the firm control the process through superior bargaining power. Moreover, a debt-for-equity exchange to remove all existing debt takes place just before investment that is followed by the issue of an optimal amount of new debt as part of the funding for the investment cost. The optimal investment trigger is higher along the optimal restructuring path than it is for an unlevered firm. We discuss the findings in the light of existing empirical evidence.

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.
