基于期权定价的基本理论，研究美式看涨期权与欧式看涨期权之间的关系；在Black-Sc holes公式假设条件下，利用鞅和停时理论，得美式看涨期权的价格与欧式看涨期权的价格相等；探讨美式看跌期权价格的数字化计算，在相关假设条件下，利用基于最优化时的变分不等式证明了美式看跌期权价格的有界性，并介绍了几种美式看跌期权价格的数字化计算方法。

A 45-percentage-point drop in the average recommended exposure level, especially in so short a period of time, suggests that by no means are we seeing the kind of stubbornly held bullishness that is a hallmark of major market tops.

众所周知，当牛市真正到达顶部的时候，在投资者当中占据统治性地位的，应该是一种不论行情如何恶化都顽固看涨的情绪，而我们现在所看到的情况显然并非如此。

The paper studies the distribution characteristics and determinants of job vacancies. The parameter estimation is based on the two-stage Tobit procedure. The main statistical results are as follows: There is a positive correlation between the hiring scale and job vacancy incidence, while there is a negative correlation between the qualification vacancy rate and the hiring scale. The higher the labor turnover rate in units, the higher the job vacancy incidences and the vacancy rates are. The 98.39% of institutions with prospects have labor needs, and 39.53% of units declining say they will hire new staff. After decomposing the Theil Index which reflects the gaps among vacancy rates, the differences among vacancy rates of different units are mainly from the inner causes of various groups, and the intergroup reasons are not main ones.

本文利用两阶段Tobit模型对国内的职位空缺统计数据进行了估计，发现：用人机构的雇佣规模与职位空缺发生率正相关，而职位空缺率则与机构的雇佣规模呈现负相关的关系；机构员工流动率越高，职位空缺发生率以及职位空缺率越高；在景气指数为"看涨"的机构中98.39%表示存在用人需求，而景气指数为"看跌"的机构里只有39.53%的机构表示会招募新员工；在对反映职位空缺率差距水平的泰尔指数分解后发现机构职位空缺率之间的不同主要是由于各类分组的组内原因导致的，而组间的原因并不是主要的。

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。

A popular strategy is selling covered calls. Mike Pera, a 65-year-old retiree in Eagle River, Wis., does that regularly by selling call options on stock he already owns.
