在投资、建设、运营和移交的过程中,PPP项目价值是利益各方关注的首要问题.在PPP项目全寿命期周期内,市场环境、政策以及决策者本身带来的不确定性都可能影响项目的价值,此类价值很难通过传统的评价方法计算,而需要借助实物期权的思想来获得.本文在相关研究的基础上,提出了基于模糊实物期权的PPP项目价值评估一般步骤:资料收集与整理、项目价值分析、实物期权界定与分析、项目价值计算、敏感性分析、得出结论.然后,推导出模糊实物期权价值计算模型,并应用于香港迪斯尼乐园二期项目实物期权价值评估,得出项目价值范围.最后对模型进行讨论,结果分析表明该项目价值受资产现值影响最大,建设、运营成本和建设时间次之. 相似文献

根据北京地铁4号线PPP项目遇到的实际问题构建模型,将实物期权理论引入解决车站停车场建设规模决策的问题.通过设计Excel表计算引入实物期权后不同方案的期望NPV,既解决了一般期权定价困难的问题,又将期权理论与PPP项目紧密结合,发现实物期权对于PPP项目决策过程的优化起到了非常明显的作用.特别是处理不确定性给PPP项目的谈判、决策、执行过程造成困难时,实物期权能够发挥更大的作用,可以作为决策者改善决策合理性的手段,也可以为公私双方化解核心矛盾取得一致意见提供有效帮助. 相似文献

基于价值权力的战略管理方法和模型 总被引:1,自引:0,他引:1
实物期权方法近年来在战略投资领域得到了广泛应用,但在战略管理领域中的应用却没有得到更进一步的发展。本文试图找到实现实物期权思想在战略管理领域更广泛应用的途径。通过扩展实物期权概念的内涵,本文引申出价值权力的概念,提出了基于价值权力进行战略分析和管理的思路,并进一步构建了进行价值权力分析和管理的直观工具,为在变化日益加速的不确定性环境下对企业战略进行全面的分析和管理提供了一个新的视角和相关模型。 相似文献

为突破传统实物期权在 CCS 投资决策中未考虑非随机不确定性的不足, 本文将三角模糊数和二叉树期权模型相结合, 构建 CCS 投资决策的模糊实物期权模型框架, 并通过实证分析对模型和判断规则进行可靠性验证。 研究表明: (1) 模糊实物期权框架下的 CCS 投资价值受到左展形 α、 右展形 β 和置信水平 γ 的影响; (2) 当 0≤γ≤0.68 时, 投资决策需要考虑投资者的个人主观因素。 该方法更适应于灵活多变的投资环境, 尤其是像 CCS 投资这种政策依赖性强的商业活动。 对于无法用随机性刻画的不确定性因素, 投资者可以根据风险偏好、 管理经验和内外部消息对未来进行合理预估, 从而提高投资决策的准确性和有效性。 相似文献

基于决策树和二叉树的整合模型是目前比较可行的一种实物期权定价方法。该方法把影响项目经济价值的所有不确定性分为两类——市场不确定性和技术不确定性。本文利用该方法对一个位于阿塞拜疆的实际石油项目进行了评价,识别出了对项目经济性具有较大影响的5个不确定性因素(输入变量):油价、投产初期产量(Initial Production Rate)、递减率(Decline Rate)、总投资(CAPEX)和操作成本(Variable Cost)。通过分析,该项目可能存在多种实物期权。利用该整合模型并应用DPL软件建模估算了这一石油项目的扩张期权、放弃期权和复合期权的价值。 相似文献

在油田领域,学者们对实物期权法的研究一方面集中于识别与构造油田勘探开发中的实物期权,另一方面集中于实物期权法在油田经济评价中的应用研究。国外学者在陆上油田投资、海上油田投资、油田开发时机的选择以及战略和风险投资领域对实物期权法的研究与应用方面作出了较大贡献。国内的研究机构和学者虽然进行了一些研究,但是实物期权法在国内油田勘探开发领域还没有得到足够的重视,针对油田具体实际情况进行实物期权法的应用研究很少。实物期权法在油田经济评价中的应用特点包括:重视对不确定性因素的研究,将风险评估与效益评价相结合,注重灵活性的价值,与其他方法结合使用。为了更好地在油田经济评价中应用实物期权法,需要全面推广实物期权的思想,建立一般意义上的实物期权模型,识别勘探开发项目中的实物期权,开发出简单实用的应用软件。 相似文献

Equilibrium Real Options Exercise Strategies with Multiple Players: The Case of Real Estate Markets 总被引:3,自引:0,他引:3
This article derives a closed-form solution for an equilibrium real options exercise model with stochastic revenues and costs for monopoly, duopoly, oligopoly and competitive markets. Our model also allows one option holder to have a greater production capacity than others. Under a monopolistic environment we find that the optimal option exercise strategy in real estate markets is dramatically opposite to that in a financial (warrant) market, indicating the importance of paying attention to the institutional details of the underlying market when analyzing option exercise strategies. Our model can be generalized to the pricing of convertible securities and capital investment decisions involving both stochastic revenues and costs under different types of market structures. 相似文献

面对日渐繁荣的中国房地产市场,房价涨幅过快、过高已经是一个不容回避的问题。房地产期权作为一种创新型投资理财工具,在欧美和亚洲金融衍生品市场几乎完全空白,能够有效对冲房价过快上涨的风险,改变中国购房者传统购房观念,间接缓解房地产价格过快上涨的压力。本文基于中国市场对以房地产价格为标的物的期权产品进行研究,以西安市房地产市场为例进行模拟分析,结果表明,房地产期权可以满足普通购房者对冲房价过快上涨的避险需求,转变传统购房观念,缓解短期购房压力,降低房地产市场的整体风险,在一定程度上促进房地产市场平稳有序的发展,具有十分显著的现实应用价值。 相似文献

Commercial Office Space: Testing the Implications of Real Options Models with Competitive Interactions 总被引:1,自引:0,他引:1
We test the implications of real option pricing models with competitive interactions for commercial real estate development. The competitive nature of a local commercial real estate market relies on a Herfindahl ratio derived from individual developers' shares of total office construction in their market. All else being equal, greater competition among local developers is associated with more building starts. Other variables suggested by the real options pricing model, including the volatility of local lease rates, are also found to be statistically important. In addition, we provide evidence consistent with greater competition attenuating the extent to which increases in volatility delay commercial real estate development. 相似文献

Research Summary: We develop a behavioral theory of real options that relaxes the informational and behavioral assumptions underlying applications of financial options theory to real assets. To do so, we augment real option theory's focus on uncertain future asset values (prospective uncertainty) with feedback learning theory that considers uncertain current asset values (contemporaneous uncertainty). This enables us to incorporate behavioral bias in the feedback learning process underlying the option execution/termination decision. The resulting computational model suggests that firms that inappropriately account for contemporaneous uncertainty and are subject to learning biases may experience substantial downside risk in undertaking real options. Moreover, contrary to the standard option result, greater uncertainty may decrease option value, making commitment to an investment path more effective than remaining flexible. Managerial Summary: Executives recognize the need to make uncertain investments to grow their business while mitigating downside risk. The analogy between financial options and real corporate investments provides an appealing method to consider the practical challenge of such investment decisions. Unfortunately, the “real options” analogy seems to break down in practice. We identify how a second form of uncertainty confounds real options intuition, leading managers to overestimate the value of uncertain investments. We present a behavioral real options model that accounts for both forms of uncertainty and suggest how uncertainty interacts with behavioral bias in the option execution/termination decision. Our model facilitates assessment of the conditions under which investments in uncertain opportunities are usefully considered as real options, and provides a means to evaluate their attractiveness. 相似文献

Real options reasoning emphasizes the strategic value of making flexible investments in a turbulent environment. Employees' investments in specific human capital are often critical to the success of a real option project, but the very flexibility that allows a firm to change course in response to new information also affects employees' incentives to make such specific human capital investments. We develop a model of real option investment that explicitly incorporates the role of employee incentives. The model suggests that the effect of investing in a real option project on employee incentives may be positive, further increasing the value of the project, or negative, sometimes more than offsetting the benefit of flexibility and resulting in reduced project value. Therefore, firms and managers should take into consideration the role of employee incentives when applying real options logic to investment decision making.

This paper considers the problems peculiar to options on real estate, because of the special set of institutional factors influencing real estate markets. It is intended to serve as a reply to Johnson and Wofford [15] as well as provide an overall critique of option-pricing models in a real estate context. Our major point is that a variety of real estate decisions, such as the abandonment decision, the option to refinance, or the option to exercise a contingent real estate purchase contract, may be modeled using option-pricing techniques. However, both the theoretical and institutional aspects of real estate markets must be taken into account in both developing and applying option models in a real estate context. 相似文献
