基于Wiener过程和Poisson测度的利率期限结构模型:存在性和正性

Term Structure Models Driven by Wiener Process and Poisson Measures: Existence and Positivity

Damir Filipovic, Stefan Tappe, Josef Teichmann

摘要:

在Björk-DiMasi-Kabanov-Runggaldier的理论基础上,本文研究了波动率依赖于远期曲线的由Wiener过程和Poisson测度驱动的利率期限结构模型.这包括一个完整的存在性和唯一性证明相应的Heath-Jarrow-Morton型期限结构方程。此外,我们还利用特征系数刻画了保正模型,这对于跳扩散模型是开放的。此外,我们还讨论了带跳的利率理论的Brody-Hughston方程解的存在性、唯一性和正性,我们认为这个方程对实际应用是非常有用的。在我们的调查中发挥了关键作用的方法的活动标架,它允许转换的Heath-Jarrow-Morton-Musiela方程的时间相关的时间。

英文摘要:

In the spirit of Björk-DiMasi-Kabanov-Runggaldier, we investigate term structure models driven by Wiener process and Poisson measures with forward curve dependent volatilities. This includes a full existence and uniqueness proof for the corresponding Heath--Jarrow--Morton type term structure equation. Furthermore, we characterize positivity preserving models by means of the characteristic coefficients, which was open for jump-diffusions. Additionally we treat existence, uniqueness and positivity of the Brody-Hughston equation of interest rate theory with jumps, an equation which we believe to be very useful for applications. A key role in our investigation is played by the method of the moving frame, which allows to transform the Heath--Jarrow--Morton--Musiela equation to a time-dependent SDE.
