In Chapter 4, the pricing of Asian geometric average option under stochastic interest rates is studied, assuming CIR model for the interest rates. Asian option is strongly dependent with path, usually have a long duration, the movement of interest rates becomes more important in pricing such long-dated options. The CIR interest rate model not only considered the interest rate behavior has mean-reverting but also take into account that the fluctuation rate is direct proportion with the square root of its interest rate. Finally, the method of finite difference for the Asian geometric average option under CIR interest rate model is given.

第四章在利率满足CIR利率模型的假设下，研究了几何亚式期权的定价公式，亚式期权是强路经依赖性期权，通常有效期较长，在进行较长时期的投资时，利率的变化是非常重要的，CIR利率模型不仅考虑了利率行为具有均数回归的现象，而且还考虑其波动性的大小与利率大小的平方根成正比，最后给出了CIR利率模型下的几何亚式期权定价的有限差分法。

4Based on a fact that the price formula of Asian options can be transformed into that of vanilla European option when the time to maturity is less than or equal to the length of average, we skillfully obtain the analytical price formula for the option on the minimum or the maximum of two geometric average prices and generalize it to obtain the price formula of several average prices for the first time. We also apply the method of [121], which approximates the arithmetic average by the geometric average, to the pricing of opitons on the minimum or the maximum of two arithmetic average prices to obtain Its approximated price formula. Numerical results show that the approximated price is relatively accurate when the riskless interest rate is large or the option is in the money and the volatility of two underlying assets are high and its accuracy is a little reduced but still good when the dividends are considered. However, it is hardly affected by the sampling number.

我们基于观察到的一个事实即当离到期时间小于或等于平均期间时亚洲期权的价格可变换成普通的欧式期权的价格，从而巧妙地得到了两个几何平均价格的最小或最大值期权价格的解析公式，通过简单地推广，首次得到了多个几何平均时的价格公式；将[121]用于算术平均亚洲期权的定价方法推广到两个算术平均价格的最小或最大值期权，从而得到它的渐进公式，数值结果表明：渐进价格的准确性在无风险利率较大或期权为实值且两标的资产的波动率较小时较好，抽样的个数对它没有影响，但考虑红利时它稍有下降但仍较好。

In financial mathematics, the implied volatility of an Option contract is the volatility implied by the market price of the option based on an option pricing model.

在金融数学里，一个期权和约的隐含波动性是根据期权定价模型由市场价格所暗示的波动性。

Because of embedded option, the cash flow of callable bond is not certain. Fortunately, it has the same future cash flow as the portfolio of one long noncallable bond and one short call option on the callable payments. So under a nonarbitrage condition, the value of callable bond equals the difference of the value of noncallable bond and call option.

由于内嵌看涨期权的存在，可赎回债券的预期现金流事先并非确定，但因其未来的现金流表现与持有可比普通债券和卖空看涨期权的投资组合相同，故而可赎回债券的价格在无套利条件下应等于可比普通债券减去看涨期权的差值，也就是说用于普通债券的一般定价和度量方法并不适用于此种特殊的选择权债券。

In order to make use of the technical bonus stock distribution mechanism fully,inspire the talent of technologists,encourage their devotion to films,we have some important discussion on the technical bonus stock distribution policy,introduce the distributed models of technical bonus stock,point out the questions in the excutive course,and offer the solution correspondingly.In the third part,we discuss the technical stock option design on middle-small technical films,and consider the logical thoughtfulness in the course of reanimation as follows:the more outstanding achievement for the powered man→the more increase on special target→the lower price on technical option premium→the more profit→the more effective reanimation.In the parameter,a set of detailed program is designed,which includes establishment of incentive fund,institution of merit system for the plans grantors,award of stock option,determination of premium,so as to reduce random in the incentive course,have a great effect on the mormative management for themiddle-small technical films.
