摘要
研究了Knight不确定环境下的Lévy型金融市场.假设标的股票价格服从Lévy过程,借助Lévy-Laplace指数建立了欧式期权的动态定价模型,得到了定价区间,并针对Lévy纯跳过程给出了模型的显示解.最后,利用数值分析方法,研究了Knight不确定性参数对欧式看涨期权定价区间的重要影响.
The Lévy financial market under Knight uncertainty was studied.Assuming the underlying stock asset following Lévy process,we established the supper and lower bounds model of European options by Lévy-Laplace exponent and got the interval of option price.Moreover,for pure jump Lévy process,the explicit solutions were given.Finally,the important impact of Knight uncertainty on the pricing of European options was studied through numerical analysis.
