本地化波动

Localizing Volatilities

Marc Atlan

摘要:

我们提出了Gyöngy(1986)的非齐次马尔可夫随机微分方程的构造的两个主要应用,该方程模拟了连续伊藤过程的一维边缘。首先证明了Dupire(1994)和Derman和Kani(1994)的结果。然后,我们提出了贝塞尔为基础的随机波动率模型,在这种关系是用来计算本地波动率的解析公式。其次,我们使用这些模仿技术,以扩展著名的本地波动率的结果,随机利率框架。

英文摘要:

We propose two main applications of Gyöngy (1986)'s construction of inhomogeneous Markovian stochastic differential equations that mimick the one-dimensional marginals of continuous Itô processes. Firstly, we prove Dupire (1994) and Derman and Kani (1994)'s result. We then present Bessel-based stochastic volatility models in which this relation is used to compute analytical formulas for the local volatility. Secondly, we use these mimicking techniques to extend the well-known local volatility results to a stochastic interest rates framework.
