给出动态随机弹性的概念及运算性质,讨论了动态随机弹性在期权定价模型中的应用.主要结果有:(1)在波动率为常数时,期权价格对的弹性,得到了动态随机弹性服从运动,并给出了相应的经济解释;(2)由于波动率一般不是常数,也是随机过程,因此本文进一步研究了期权价格对波动率的弹性,就股票价格的波动情况给出了数学描述和金融意义上的解释.
The dynamic stochastic elasticity is introduced and its applications on the pricing option models are discussed. The main results: (1) When the volatility is constant, the pricing option to B(t)'s elasticity is follows Brown motion process and the economic explain is given; (2) The pricing option to volatility's elasticity is further discussed because the volatility is not a constant but a stochastic process. The principium explains on the finance and the mathematical descriptions according to the fluctuation of the stock price are given.
