Abstract:

The polynomial spline model, which belongs to the static term structure model of interest rates, is studied.Every cash flow of the project is discounted relatively accurately by obtaining the discount rate from the static term structure model of interest rates.A simple basic model, which belongs to the dynamic term structure model, is studied, and the option pricing formula under changing risk-free rates is obtained by bringing it into the option pricing formula.Both dynamic and static term structure models are estimated by the use of the data of buy-back rates and the Shanghai Stock Exchange, and an example is given to compare the differences between the traditional method and the method under the changes in the interest rates and the discount rates.

研究了利率期限结构静态模型中的多项式样条模型, 并在此基础上得到折现率估计模型, 从而对项目各期现金流进行相对准确的折现计算.研究了利率期限结构动态模型中的一个简单的基本模型, 并将其纳入到期权定价公式中, 得到利率动态变化下的期权定价公式.分别利用我国银行间回购利率数据、上海证券交易所数据估计出我国利率动态基本模型和静态多项式样条模型, 给出一个实例对传统实物期权定价方法和考虑无风险利率、折现率变化时的实物期权定价方法进行了比较.
