借助测度变换获得数字幂型期权的一般定价公式,在利率服从扩展的Vasicek利率模型时,利用鞅理论和Girsanov定理,得到了数字幂型期权的精确定价公式.
A general pricing formula for digital power-option is derived by measurement transformation. Then an analytic pricing formula for digital power-option is given in an extended Vasicek interest rate framework by applying the martingale theory and Girsanov theorem.
