基于矩匹配的、多标的实物期权估值方法研究

通过采取实物期权分析在实际使用过程中通常会对应多个标的物,利用现有方法无法求解变量和价值敏感性会影响其适用性,在本研究中将多个标的资产作为资产组合,通过采取矩匹配方式获取组合资产近似分布图,进一步能够求解多标的实物期权,通过实例分析该方法的优势。     

实物期权的资源能力基础

目前在实物期权的研究工作中,对于实物期权的资源能力基础尚缺乏研究,在实物期权产生于资源、能力与市场机会的匹配上,其价值不仅取决于执行价格、标的资产的价格等,还取决于自身的能力、资源和市场竞争等因素。     

脆弱期权定价模型

实物期权在信息经济分析中的应用——以数字图书馆为例

信息经济作为近些年来新兴起的经济形式,对社会经济的发展起到了重要的推动作用。而数字图书馆作为信息经济的载体,其产生的价值获得了众多学者的关注。实物期权的定价方法是现代期权定价理论在具有期权特性的非交易实物资产定价中的应用。近些年来,实物期权的定价方法已经在各行各业中有了广泛的应用,因此,实物期权的方法对数字图书馆项目等信息经济项目的开发决策也有着十分重要的应用价值。     

实物期权及其在风险投资中的应用

从广义的期权定义中引出实物期权的概念,对金融期权和实物期权进行比较分析;并借鉴金融期权的定价方法,得出实物期权的定价公式。通过计算风险投资项目中实物期权的价值,比较含有实物期权的风险投资项目与一般投资项目的价值,可以看出在风险投资中引入实物期权的思想,对风险投资家做出正确的投资决策,以及对风险资本的保值增值有重大的指导意义。     

基于实物期权的R＆D项目投资决策研究

实物期权是期权应用于现实资产时以期权概念定义的现实选择权,从其投资项目中含有的不确定性和决策者的灵活性可以判定出项目的真实价值.实物期权的存在对R&D项目投资决策有一定的影响,在对传统的现金流量折现法与实物期权方法进行比较后,给出基于实物期权定价方法的R&D项目投资决策模型,并通过一个扩大R&D项目投资问题进行应用研究.     

贷款定价的期权分析及对中国银行信用风险思考

贷款定价的期权分析,将有限责任体制下的厂商借款视为购买厂商资产为标的,以贷款本金为执行价格的期权,并运用期权定价模型推出风险贷款价值及利差的计算公式,指出债务程度对厂商拖欠贷款的关键影响,从而看出中国信用风险与利率管制,贷款管理,企业制度等因素有关。     

项目投资决策中的实物期权理论分析

实物期权既是项目决策中的一种灵活的定量评估方法,也是实物资产定价的一种有效方法。本文回顾了从贴现现金流到实物期权的发展,介绍了期权定价的优点、分类和影响因素,为人们提供了在真实的商业世界中进行分析思考和竞争的有力武器。     

非交易性资产的实物期权定价研究

期权定价方法最初是针对金融市场上可交易金融资产建立起来的,与通常意义上的“交易”概念相比,资产的可交易性更为严格。我们在讨论实物资产的交易性时,不可交易资产是指由于资产并不在市场上交易,因此就无法如金融期权定价那样通过构造复制资产组合为资产期权定价,即这类资产并不满足风险中性定价的假设条件。本文就这种情况提出了一种新的解决方法。

布莱克—斯科尔斯期权定价公式的推导及推广

Black-Scholes期权定价模型是金融学中广泛应用的模型之一,该模型的提出是金融理论界和实践界的一场革命。Black、Scholes和Merton引入了动态套期保值组合的概念,期权的支付可以通过基础资产的动态组合策略复制。通过对期权定价理论的历史介绍及对该公式的几种推导方法进行分析,说明在其他金融衍生产品定价中的推广应用。     

Pricing American exchange options in a jump‐diffusion model

A way to estimate the value of an American exchange option when the underlying assets follow jump‐diffusion processes is presented. The estimate is based on combining a European exchange option and a Bermudan exchange option with two exercise dates by using Richardson extrapolation as proposed by R. Geske and H. Johnson (1984). Closed‐form solutions for the values of European and Bermudan exchange options are derived. Several numerical examples are presented, illustrating that the early exercise feature may have a significant economic value. The results presented should have potential for pricing over‐the‐counter options and in particular for pricing real options. © 2007 Wiley Periodicals, Inc. Jrl Fut Mark 27:257–273, 2007     

二叉树方法在风险投资决策中的应用

在过去的20年中,许多学者开始应用期权定价方法去估计实物资产价值,并在此基础上对公司的最优投资决策进行了大量研究。利用二叉树方法,通过对一个欧式期权与一个美式期权构成的复合期权进行定价,完成对风险投资问题的估价。主要有两个方面的内容:用实例说明怎样用二叉树方法对投资期权进行估价;把从期权模型获得的价值与用净现值方法得到的价值相关联,从而获得风险投资的最终的价值。     

法律判决经济价值效应的金融学分析

法律判决不仅体现了法律对当事人在事件中关系的判断与处置,也会由此产生对当事人乃至全社会的经济价值效应。对于前者,判决体现的是法律的判断;对于后者,传统理论普遍认为是一个零和游戏。然而,从金融学的资产定价理论出发,却发现法律判决的社会经济价值效应并非零和,而且这些价值不仅影响了社会经济活动的行为判断,还对某些资产定价的传统理论提出了挑战。     

实物期权无形资产及其价值评估研究

随着知识经济的到来及金融全球化的发展,企业无形资产的内涵和外延已拓展到智力资本及实物期权。在智力资本研究的基础上,把实物期权列入无形资产确认与计量范畴将有利于企业价值的真实反映。因此,本文将对实物期权无形资产的范畴、内涵和外延及其价值评估进行分析,以顺应新经济形势下对无形资产会计制度进行改革的现实要求。     

The Pricing of Catastrophe Equity Put Options with Default Risk

In this paper, we present a pricing model for catastrophe equity put options with default risk by assuming that the default of the option issuer may occur at any time prior to maturity of the option. Catastrophic events are assumed to occur according to a doubly stochastic Poisson process, and stock price is affected by the catastrophe losses, which follow the compound doubly stochastic Poisson process. As for default risk, we adopt typical structural approaches, and we also allow the correlation between the underlying stock and the assets of the option issuer. Under this framework, we derive a pricing formula for catastrophe equity put options with default risk. Finally, numerical analysis is presented to illustrate effects of default risk on catastrophe equity put option prices.     

项目评估法定国有资产之价

关于国有资产定价问题,各种方案从不同角度被提出并实践着,但其实际效果并不理想。追其原因,除了体制、内外环境因素等外,一个比较重要的原因就是:国有资产的价值没有真正厘定清楚。价格的确定是各种方案实施之前不容忽视的、是较难处理的问题,也将是解决国有企业、国有资产问题的关键。     

A Dynamic Investment Model with Control on the Portfolio's Worst Case Outcome

This paper considers a portfolio problem with control on downside losses. Incorporating the worst-case portfolio outcome in the objective function, the optimal policy is equivalent to the hedging portfolio of a European option on a dynamic mutual fund that can be replicated by market primary assets. Applying the Black-Scholes formula, a closed-form solution is obtained when the utility function is HARA and asset prices follow a multivariate geometric Brownian motion. The analysis provides a useful method of converting an investment problem to an option pricing model.     

Equilibrium Pricing in the Presence of Cumulative Dividends Following a Diffusion

The paper presents some security market pricing results in the setting of a security market equilibrium in continuous time. The theme of the paper is financial valuation theory when the primitive assets pay out real dividends represented by processes of unbounded variation. In continuous time, when the models are also continuous, this is the most general representation of real dividends, and it can be of practical interest to analyze such models.
Taking as the starting point an extension to continuous time of the Lucas consumption-based model, we derive the equilibrium short-term interest rate, present a new derivation of the consumption-based capital asset pricing model, demonstrate how equilibrium forward and futures prices can be derived, including several examples, and finally we derive the equilibrium price of a European call option in a situation where the underlying asset pays dividends according to an Itô process of unbounded variation. In the latter case we demonstrate how this pricing formula simplifies to known results in special cases, among them the famous Black–Scholes formula and the Merton formula for a special dividend rate process.     

CONSTANT PROPORTION PORTFOLIO INSURANCE IN THE PRESENCE OF JUMPS IN ASSET PRICES

Constant proportion portfolio insurance (CPPI) allows an investor to limit downside risk while retaining some upside potential by maintaining an exposure to risky assets equal to a constant multiple of the cushion , the difference between the current portfolio value and the guaranteed amount. Whereas in diffusion models with continuous trading, this strategy has no downside risk, in real markets this risk is nonnegligible and grows with the multiplier value. We study the behavior of CPPI strategies in models where the price of the underlying portfolio may experience downward jumps. Our framework leads to analytically tractable expressions for the probability of hitting the floor, the expected loss, and the distribution of losses. This allows to measure the gap risk but also leads to a criterion for adjusting the multiplier based on the investor's risk aversion. Finally, we study the problem of hedging the downside risk of a CPPI strategy using options. The results are applied to a jump-diffusion model with parameters estimated from returns series of various assets and indices.
