我们推导了巨灾股票看跌期权(CatEPuts)的定价公式,假设巨灾事件遵循马尔可夫调制泊松过程(MMPP),其强度根据大西洋年代际振荡(AMO)信号的变化而变化。1960年至2007年的美国飓风事件表明,MMPP(2)下的CatEPuts定价误差比PP小30%至66%。情景分析表明,MMPP优于指数增长模式(EG),如果飓风强度是AMO信号,而EG可能优于MMPP,如果未来气候变暖迅速。
We derive the pricing formula for catastrophe equity put options (CatEPuts) by assuming catastrophic events follow a Markov Modulated Poisson process (MMPP) whose intensity varies according to the change of the Atlantic Multidecadal Oscillation (AMO) signal. U.S. hurricanes events from 1960 to 2007 show that the CatEPuts pricing errors under the MMPP(2) are smaller than the PP by 30 percent to 66 percent. The scenario analysis indicates that the MMPP outperforms the exponential growth pattern (EG) if the hurricane intensity is the AMO signal, whereas the EG may outperform the MMPP if the future climate is warming rapidly.
