英文摘要:
We introduce a general decision tree framework to value an option to invest/divest in a project, focusing on the model risk inherent in the assumptions made by standard real option valuation methods. We examine how real option values depend on the dynamics of project value and investment costs, the frequency of exercise opportunities, the size of the project relative to initial wealth, the investor\'s risk tolerance (and how it changes with wealth) and several other choices about model structure. For instance, contrary to stylized facts from previous literature, real option values can actually decrease with the volatility of the underlying project value and increase with investment costs.

中文摘要:
我们引入了一个通用决策树框架来评估项目投资/剥离期权的价值,重点关注标准实物期权估值方法所做假设中固有的模型风险。我们研究了实物期权价值如何取决于项目价值和投资成本的动态、行使机会的频率、项目相对于初始财富的规模、投资者的风险承受能力(以及风险承受能力如何随财富变化)以及关于模型结构的其他几种选择。例如,与以往文献中的程式化事实相反,实物期权价值实际上可以随着基础项目价值的波动而减少,而随着投资成本的增加而增加。
