大波动率情形下的一个新的市场模型

A new market model in the large volatility case

Yukio Hirashita

摘要:

我们将比较三种类型的价格,即理性(套期保值)价格,几何(增长率)价格和鞅(措施)价格。我们将证明,完全市场理论中的理性价格有时是与常识相反的。在连续时间的情况下,我们坚持认为,市场模型之间的小波动率的情况下,大波动率的情况下,应该有所不同。

英文摘要:

We will compare three types of prices, namely, rational (hedging) prices, geometric (growth rate) prices, and martingale (measure) prices. We will show that rational prices in the complete market theory are sometimes contrary to common sense. In the continuous-time case, we insist that the market model should differ between the small volatility case and the large volatility case.
