采用实物期权与均衡定价理论,研究委托-代理冲突下的企业投融资决策问题.考虑管理者拥有企业投融资决策权时,其如何同时选择投资时机、投资规模及资本结构.分析了管理者持股与项目风险(不确定性)对企业非效率投融资的影响.数值分析表明:给定资本结构下,杠杆企业管理者决策的投资时机与投资规模变化呈现出负相关;对比于纯股权融资企业,杠杆企业管理者加速了投资期权的执行并增大了投资规模;财务杠杆率是管理者持股比例的U形函数,且管理者持股比例的增大,会加速投资期权的执行、增大投资规模与债务融资规模,并降低代理成本;项目风险的增大会导致企业投资时机、投资规模、债务融资规模和代理成本增大及财务杠杆率降低.  相似文献

本文利用我国2009~2018年2193家地方融资平台的面板数据,采用基准回归模型和中介效应模型,分析了43号文件对地方融资平台期限错配的治理效应,并进一步分析了债务治理是如何通过缓解地方融资平台期限错配最终改善企业绩效的。结果表明:(1)43号文改善了地方融资平台期限错配问题,并增加了企业绩效,这一结论在稳健性检验中也得到了验证;(2)43号文改善了省及省会(单列市)类地方融资平台的期限错配问题,并相应的改善了企业的绩效;(3)43号文改善了土木工程类和房地产类地方融资平台的期限错配问题,并相应的改善了企业的绩效。  相似文献

随着地方政府债券发行规模的扩大,地方政府债务的信用风险日益凸出。本研究以企业债信用风险缓释工具的推出为契机,借鉴结构化模型的思路和KMV模型求解违约概率的逻辑,通过Monte Carlo方法模拟地方政府的违约过程,直接测算地方政府的整体违约概率;结合简约化模型的思路测算地方政府债券的具体违约概率,计算信用风险缓释工具的理论价格,从而构建了地方政府债券信用风险缓释工具的混合定价模型。研究发现,以企业债券为标的测算出的模型理论价格与市场报价基本一致,参数的敏感性检验进一步验证了模型的理论自洽性和实证可靠性。上述结论或将为新《预算法》实施过程中地方政府债务的治理与掌控及中国区域性、系统性金融风险的防范提供新思路。  相似文献

选取2003-2015年我国沪深A股上市公司中有境外机构投资者(QFII)持股的公司作为研究样本,将QFII持股周期划分为短期、中期和长期三类,通过理论分析和实证分析研究QFII不同持股周期对上市公司治理绩效的影响,研究结果表明,QFII短期持股时,奉行财务投资理念,通过买卖价差获取投资收益,不会对公司治理绩效产生影响;QFII中期持股时,会对公司治理绩效产生影响,但影响作用较微弱;QFII长期持股时,主要奉行价值投资理念,通过积极参与公司治理影响公司治理绩效,获得高额投资收益。本文的研究结论对我国境内机构投资者和上市公司具有一定的借鉴作用,同时可以为我国引入QFII提供政策建议。  相似文献

We suggest a methodology for valuing corporate securities that allows the straightforward derivation of closed form solutions for complex scenarios. The tractability of the framework stems from its modularity-we provide a number of intuitive building blocks that are sufficient for valuation in typical situations. A further advantage of our approach is that it makes economic interpretation far easier than what is typically possible with other approaches, such as solving systems of partial differential equations. As examples we consider a corporate coupon bond with discrete payments, and debt subject to strategic debt service.  相似文献

In this paper, we study the calibration problem for the Merton–Vasicek default probability model [Robert Merton, On the pricing of corporate debt: the risk structure of interest rate, Journal of Finance 29 (1974) 449–470]. We derive conditions that guarantee existence and uniqueness of the solution. Using analytical properties of the model, we propose a fast calibration procedure for the conditional default probability model in the integrated market and credit risk framework. Our solution allows one to avoid numerical integration problems as well as problems related to the numerical solution of the nonlinear equations.  相似文献

Banks and other financial institutions issue hybrid capital as part of their risk capital. Hybrid capital has no maturity, but, similarly to most corporate debt, includes an embedded issuer’s call option. To obtain acceptance as risk capital, the first possible exercise date of the embedded call is contractually deferred by several years, generating a protection period. We value the call feature as a European option on perpetual defaultable debt. We do this by first modifying the underlying asset process to incorporate a time-dependent bankruptcy level before the expiration of the embedded option. We identify a call option on debt as a fixed number of put options on a modified asset, which is lognormally distributed, as opposed to the market value of debt. To include the possibility of default before the expiration of the option we apply barrier options results. The formulas are quite general and may be used for valuing both embedded and third-party options. All formulas are developed in the seminal and standard Black–Scholes–Merton model and, thus, standard analytical tools such as ‘the greeks’, are immediately available.  相似文献

We propose a structural model with a joint process of tangible assets (marker) and firm status for the pricing of corporate securities. The firm status is assumed to be latent or unobservable, and default occurs when the firm status process reaches a default threshold at the first time. The marker process is observable and assumed to be correlated with the latent firm status. The recovery upon default is a fraction of tangible assets at the time of default. Our model can evaluate both the corporate debt and equity to fit their market prices in a unified framework. When the two processes are perfectly correlated, our model is reduced to the seminal Black–Cox model. Numerical examples are given to support the usefulness of our model. A previous version of this paper was presented at the Tsukuba–Stanford workshop held at Stanford University on March 2006. The authors are grateful to participants of the workshop for helpful discussions.  相似文献

基于信息披露理论和公司治理理论,本文实证检验了信息披露质量对公司风险承担的影响。实证结果发现:较高的信息披露质量有助于提高公司风险承担水平,从而验证了信息披露的“治理效应”。进一步发现,管理层持股激励能够影响上市公司的信息披露行为,并提高公司风险承担水平,说明管理层持股能够加强信息披露质量与公司风险承担之间的正向关系,且这种影响关系在高管理层持股组中更显著。研究结论不仅丰富和拓展了信息披露和公司风险承担的相关研究,而且对管理层激励契约的设计和公司风险认知具有重要的启示作用和现实意义。  相似文献
