假设股票价格服从对数正态分布,且股票价格的波动率,无风险利率均为时间的确定性连续函数,利用鞅的方法研究了连续时间下的可分离债券的定价,并得到了可分离债券的定价公式.
Suppose the stock price obeys the logarithm normal distribution and the stock price volatility and the risk-free interest rate are deterministic continuous functions of time. The martingale method is used to study the pricing of separable bonds under continuous time and the separability Bond pricing formula.
