严格按照期权定义,以股票期末价值和敲定价格之差大于零作为期权行权条件利用保险精算方法讨论了债券的利率和股票的预期收益率具有时间相依的情形下的广义欧式期权定价问题,推广郑红等人的结果,导出广义Black-Scholes期权定价公式为实践中合理确定期权价格提供理论参考依据.
In strict accordance with the definition of option, the difference between the final value of the stock and the finalized price is greater than zero. As an exercise condition of the option, the security actuarial method is used to discuss the interest rate of the bond and the expected return rate of the stock. With the time-dependent pricing of generalized European options, Zheng Hong et al. The results show that the generalized Black-Scholes option pricing formula can provide a theoretical basis for the reasonable determination of the option price in practice.
