SSRJD随机强度模型下违约互换定价的精确公式
An exact formula for default swaptions' pricing in the SSRJD stochastic intensity model
摘要:
我们开发并测试了一个快速,准确的半解析公式的背景下,移位平方根跳跃扩散(SSRJD)的默认强度模型的单名默认互换。该模型可以根据CDS期限结构和一些违约掉期进行校准,以一致地定价和对冲其他信用衍生品。我们用数值实验表明,该模型隐含着合理的波动率微笑。
英文摘要:
We develop and test a fast and accurate semi-analytical formula for single-name default swaptions in the context of a shifted square root jump diffusion (SSRJD) default intensity model. The model can be calibrated to the CDS term structure and a few default swaptions, to price and hedge other credit derivatives consistently. We show with numerical experiments that the model implies plausible volatility smiles.
