An endogenous structural credit risk model incorporating with moral hazard and rollover risk

In this paper, we embed optimal contracting between the manager and equity holders into Leland-Toft endogenous structural credit risk model to study the impact of moral hazard on the firm's credit risk with rollover debts. Our model quantitatively shows that the agency costs induced by the moral hazard can endogenously have significant impacts on credit spreads, besides the costs of rolling over the maturing debts of the firm. It originates from the conflicts that these two costs should be covered by equity holders while both the manager and maturing debt holders are still paid in full. The numerical results show that the credit spread with the agency costs of moral hazard is larger than the one without the agency costs. Thus, the moral hazard could be used to explain “credit spread puzzle” as an endogenous factor. The explicit formulae of the equity value, the debt value, and the endogenous default boundary are also given.     

债务期限结构影响公司价值吗?

使用OLS多元回归分析方法研究了中国上市公司的债务期限结构对其市场价值的影响。结果表明,上市公司的长期债务比例越高,公司的市场价值越低。在自由现金流量较高的上市公司样本中,长期债务比例与公司价值间的负相关关系的显著水平和系数绝对值都明显大于在自由现金流量较低的上市公司样本中的情况。这表明,使用更多的短期债务有利于降低公司的代理成本,从而提高公司的市场价值。     

Strategic debt service and investment decisions

Firms alter investing decisions when there is debt in the capital structure. Security design features can exacerbate the situation. This article studies how strategic debt service may affect investment distortions resulting from debt financing in a dynamic framework. When the production decision involves an expansion option, the shareholders’ option to strategically default on the outstanding debt eliminates bankruptcy costs but, in contrast to previous literature where production decisions are fixed, leads to suboptimal investing decisions. This is due to higher wealth transfers from shareholders to debt holders upon exercise of the growth option. Strategic debt service, therefore, may reduce the value of the firm. The setting of an endogenous production set offers a potential explanation for empirical observations of wide credit spreads and low leverage.     

Is the use of bank debt as a governance mechanism conditioned by the financial system? The cases of Chile and Spain

We test whether the use of bank debt as a governance mechanism is conditioned by the financial system in which firms operate. Our results indicate that the legal and institutional environment determines the use of bank debt to finance growth opportunities. Firms use bank debt to finance their growth opportunities when the country's banking system contributes to solving agency and asymmetric information problems and avoiding information monopoly costs. The evolutionary process of the financial systems in each country means that market imperfections such as information asymmetry or agency costs can have a diverse influence on firms’ bank debt decisions.     

Optimal size, optimal timing and optimal financing of an investment

Corporate investment is an important determinant of economic well-being. The existing literature identifies optimal investment size and timing without the possibility of debt financing, as well as the effect of debt financing on investment timing without the option to choose investment size. This paper contributes to the literature by identifying the optimal size, optimal timing and optimal financing for an investment when the firm controls all three decisions (as it usually does in practice). The investment size and investment trigger are generally positively related: when investment is delayed (accelerated) it is larger (smaller) in size, thus the overall effect on investment is ambiguous. However, when tax rate or bankruptcy cost is increased, the trigger rises and size falls, hence the effect on investment is unambiguously negative. The effect of debt financing on investment depends on the amount of debt used; with the optimal amount of debt, investment is delayed relative to the no-debt case, and this delay can be economically significant; however, the investment, when eventually made, will be larger in size. Overall, it is not appropriate to ignore either the firm’s ability to choose investment size or its option to use debt financing, when modeling the investment decision.     

Debt, managerial compensation and learning

Using a dynamic model with uncertainty and asymmetric information, we study the impact of debt and bankruptcy on managerial compensation and learning. In this model, compensation has two roles to play—providing incentives to the manager and learning about his type. We show that debt, through bankruptcy, acts as a substitute of compensation in both dimensions and derive conditions under which debt lowers average compensation, pay-performance sensitivity and increases learning. We also examine the choice of debt and show that firm value can be increased due to debt's effect on managerial compensation, abstracting from other costs and benefits of debt. Finally, we conduct comparative statics with respect to the underlying parameters.     

Agency Cost of Debt and Credit Market Imperfections: A Bargaining Approach

This paper studies the effect of credit market imperfections, measured by the relative bargaining power of banks, on the agency costs of debt finance. The threshold of obtaining loan finance is shown to be independent of the relative bargaining power of the financier. However, lower relative bargaining power of banks leads to lower lending rates and investment return distributions with lower, but less risky returns. Thus, our analysis does not support the view, presented in a large existing literature, that there would be a trade‐off between reduced credit market imperfections and higher agency costs of debt finance.     

Investment under Uncertainty, Debt and Taxes

It is common practice in financial derivative valuation to use a discount factor based on the riskless debt rate. But, to what extent is this discount factor appropriate for cash flows emerging in capital budgeting? To answer this question, we introduce a framework for real asset valuation that considers both personal and corporate taxation. We first discuss broad circumstances under which personal taxes do not affect valuation. We show that the appropriate discount rate for equity‐financed flows in a risk‐neutral setting is an equity rate that differs from the riskless debt rate by a tax wedge due to the presence of personal taxation. We extend this result to the valuation of the interest tax shield for exogenous debt policy with default risk. Interest tax shields, which accrue at a net rate corresponding to the difference between the corporate tax rate and a tax rate related to the personal tax rates, can have either positive or negative values. We also provide an illustrative real options application of our valuation approach to the case of an option to delay investment in a project, showing that the application of Black and Scholes formula may be incorrect in presence of personal taxes.     

Debt policy, corporate taxes, and discount rates

This paper applies the standard risk-neutral valuation framework to tax shields generated by dynamic debt policies. We derive a partial differential equation (PDE) for the value of the debt tax shield. For a class of dynamic debt policies that depend on the asset's free cash flows, value, and past performance, we obtain closed-form solutions for the PDE. We also derive the tax-adjusted cost of capital for free cash flows and analyze the conditions under which the weighted average cost of capital is an appropriate discount rate. Finally, we derive closed-form solutions for equity betas, which differ from the formulas that have traditionally been used to lever and unlever equity betas.     

Optimal Sovereign Debt for an Overdebted Country

In this study, the role of debt maturity is analysed in a framework that blends a number of key macro‐economic factors with a process of estimating an optimal debt maturity maximising net present value. The purpose is to reduce the real value of government liabilities for a highly indebted country, as for example in the case of Greece, over a 35‐year period. The conclusion that emerges is that management of debt maturity is an essential component of the equilibrium policy and, as such, it can play an important role both in implementing tax smoothing programmes and in reducing costs associated with debt financing.     

Correlation at First Sight

The synthetic collateralized debt obligation (CDO) market has, over the last year, seen a significant increase in liquidity and transparency. The availability of published prices such as TracX and iBoxx tranches permits the calibration of model parameters, which was not achievable a year ago. This paper details what we believe has become the market standard approach in CDO valuation. The valuation model is introduced and analysed in depth to develop a better practical understanding of its use and the implications of parameter selection and calibration. In particular, we examine the idea that correlation within a copula model can be seen to be an equivalent measure to volatility in a standard B&S option framework and, correspondingly, we seek to calibrate smile and skew.     

Management Buyouts and Firm–Level Productivity: Evidence from a Panel of UK Manufacturing Firms

This paper presents an empirical investigation of the productivity effects of UK management buyouts (MBOs) over the period 1986–1997. It is the first study to use an augmented production function approach in order to determine and quantify: the Hicks–neutral productivity, the marginal productivity of labour, and the marginal productivity of capital effects of MBOs. The main findings are consistent with MBOs providing incentive and control systems that lead to improved firm–level productivity in the post–buyout organisation via reduced agency costs, debt bonding, and monitoring by buyout specialists.     

Financial Frictions and Risky Corporate Debt

We offer clarifications on Cooley and Quadrini (2001) regarding financial frictions and risky corporate debt pricing. Even in a frictionless world, the promised rate on corporate debt is not identical across firms and across capital structures and it is not equal to the risk-free rate. Frictions are unnecessary for credit spreads to arise. Only if the macroeconomy is in actuality risk free or risk neutral do interest rates on corporate debt reflect default probabilities. To the extent that the firm's entire financial structure is traded, a bias in credit spreads introduces an exploitable arbitrage opportunity. Re-establishing no-arbitrage, firm dynamics move in the opposite direction to Cooley and Quadrini's.     

Investor Protections and Concentrated Ownership: Assessing Corporate Control Mechanisms in the Netherlands

Abstract. The Berle–Means problem – information and incentive asymmetries disrupting relations between knowledgeable managers and remote investors – has remained a durable issue engaging researchers since the 1930s. However, the Berle–Means paradigm – widely dispersed, helpless investors facing strong, entrenched managers – is under stress in the wake of the cross‐country evidence presented by La Porta, Lopez‐de‐Silanes, Shleifer and Vishny, and their legal approach to corporate control. This paper continues to investigate the roles of investor protections and concentrated ownership by examining firm behaviour in the Netherlands. Our within‐country analysis generates two key results. First, the role of investor protections emphasized in the legal approach is not sustained. Rather, firm performance is enhanced when the firm is freed of equity market constraints. Second, ownership concentration does not have a discernible impact on firm performance, which may reflect large shareholders' dual role in lowering the costs of managerial agency problems but raising the agency costs of expropriation.     

Bureaucratic Decision Costs and Endogenous Agency Expertise

This article analyzes the effect of the cost that an agencymust incur to adopt a new regulation (the "enactment cost")on the agency's incentive to invest in expertise. The effectof the enactment cost on agency expertise depends on whetherthe agency would regulate if it fails to acquire additionalinformation about the regulation's effects. If an uninformedagency would regulate, increasing enactment costs increasesagency expertise; if an uninformed agency would retain the statusquo, increasing enactment costs decreases agency expertise.These results may influence the behavior of an uninformed overseer,such as a court or legislature, that can manipulate the agency'senactment costs. Such an overseer must balance its interestin influencing agency policy preferences against its interestin increasing agency expertise. The article discusses the implicationsof these results for various topics in institutional design,including judicial and executive review of agency regulations,structure-and-process theories of congressional oversight, nationalsecurity, criminal procedure, and constitutional law.     

中国银行体系关系型信贷的有效性——基于宣告效应的研究

在不对称信息下,关系型银行可以利用信息优势参与借款企业治理,降低代理成本.文章实证分析了1996-2008年中国上市公司发布获得银行信贷公告后的市场反应,发现上市公司发布获得银行授信和债务重组公告引起股价显著上涨,表明中国银行体系自1996年以来有意识地建立长期稳定的银企合作关系的政策具有治理效应.文章还发现,信息不对称程度越高、公司治理越差的公司,治理效应越显著.这种效应主要体现在贷前甄别企业质量和贷后救助方面,而在贷中监督企业机会主义行为,降低代理成本方面则没有体现.     

双重代理成本与债务治理机制的有效性——来自我国上市公司的证据(1998-2006)

本文在经典观点的基础上探讨了我国转型期上市公司债务治理对双重代理成本的制衡机制.通过本文的实证研究发现,债务对代理成本Ⅰ(管理者和股东之间的代理成本)的约束作用不明显,对于国有企业而言,大量的债务甚至为管理者的在职消费提供了现金流支持.债务治理机制对于代理成本Ⅱ(控股股东与小股东之间的代理成本)具有正反两面的作用.文章说明我国上市公司的债务治理绩效依赖于公司的性质及其他治理变量,需要具体细分其机制和渠道.同时,从动态演进的角度来看,我国的上市公司债务治理机制的确也在不断优化,对企业价值逐步能够起到正向作用.这对于理解我国上市公司近年来在公司治理中存在的问题具有一定的启示意义.     

Why do firms adopt CEO stock options? Evidence from the United States

This paper examines the determinants of stock option introduction as a part of CEO compensation in listed US firms during the 1994–2004 period. The results are consistent with agency costs and recruiting considerations, suggesting that firms do not adjust CEO compensation in order to address the ‘investment horizon’ problem. The findings also suggest that CEO stock option adoption is not necessarily influenced by the same factors that have been found in the literature to affect the level of CEO stock option compensation and the adoption of broad-based stock option incentives. Overall, the findings provide evidence for several theoretical predictions, thus adding to our understanding of managerial incentives.     

A model of takeovers of foreign banks

This paper investigates the determinants of the takeover of a foreign bank by a domestic bank whereby the former becomes a branch of the latter. Each bank is initially supervised by a national agency that cares about closure costs and deposit insurance payouts, and may decide the early closure of the bank on the basis of supervisory information. Under the principle of home country control, the takeover moves responsibility for both the supervision of the foreign bank and the insurance of the foreign deposits to the domestic agency. It is shown that the takeover is more likely to happen if the foreign bank is small (relative to the foreign banking market) and its investments are risky (relative to those of the domestic bank). Moreover, the takeover is in general welfare improving for both countries.
