摘要:提出了一种基于柳树状结构快速计算带有错向风险的信用估值调整的算法, 并利用信用违约互换价差数据校准违约概率, 以几何布朗运动和跳扩散模型下欧式和百慕大股票期权的数值实验为例, 表明柳树法与现有方法相比有相同的计算精度, 但计算速度更快.



Abstract:An efficient willow tree algorithm is proposed to price CVA (credit valuation adjustment) with WWR(wrong way risk), which can also calibrate the default probability by credit swap spreads. Besides, some numerical experiments are presented to illustrate the accuracy and efficiency of the proposed method.
