AI总结:

针对短期利率由非线性波动率单因子均值回复过程驱动的情况,分析了零息债券定价的解析近似公式,推导了Choi-Wirjanto近似的精度阶,并给出了高阶近似的显式公式及数值测试。

摘要:

我们分析了在短期利率由波动率非线性依赖于利率本身的单因子均值回复过程驱动的情况下,零息债券定价的解析近似公式。我们推导了Choi和Wirjanto解析近似的精度阶。此外,我们给出了高阶近似的显式公式,并针对一类单因子利率模型对两种近似进行了数值测试。

英文摘要:

We analyze analytic approximation formulae for pricing zero-coupon bonds in the case when the short-term interest rate is driven by a one-factor mean-reverting process with a volatility nonlinearly depending on the interest rate itself. We derive the order of accuracy of the analytical approximation due to Choi and Wirjanto. We furthermore give an explicit formula for a higher order approximation and we test both approximations numerically for a class of one-factor interest rate models.
