calibrate只是calibrate return dynamics
1。如果fully numerical做DP,那复杂的都能做,比如recursive preference, risk-
sensitive preference等等。
2。如果能解出closed-form analytical solution,utility不能任意复杂,一般CRRA
和部分扩展(比如habit formation, recursive preference)可以做到,而且同时
return dynamics也有限制。
3。如果是那种explicit characterization,但是需要numerical simulation的(比如
continuous-time Malliavin derivative),相对2来讲对于return dynamics限制较少
,但utility也不能复杂,比如recursive preference就不行,HARA就可以。

新手上路,刚刚装了MikTex,不太会,还在自己琢磨。
请问,有可能下载的到别人发表的文章的latex 模板么?我想这样可能学的快一点。
谢谢! |

听说现在数学搞得stochastic DE很多都不是用普通的ito calc 而是rough path,
malliavin calc, white noise distribution theory 什么的用在fBm, levy
processes上,实用的东西他们都不做。 |

K*****Y 发帖数: 629 | 6 Malliavin Calculus is designed for attacking such kind of problems.
Ok Google search了。。让我详细看看。。。谢谢:) |

那么的,你的目标是有一个payoff想要去replicate然后去hedge呢,还是基于
portfolio optimization的hedge?
第一种就是你把price算出来然后计算delta,gamma,vega等等,第二种就是你的
wealth process的Brownian-Poisson filtration下的wealth process的Malliavin
derivatives
其实想法和没有jump是一样的,technique不一样而已。 |

Malliavin derivatives (Nualart 1995),求起来很方便。BS假设constant vol,即使
你用implied vol加进去,在你的hedging term也不会有对未来不确定的vol的对冲项。
(本质上Mallavin derivative就是把Brownian motion perturbate一个很小的量看未
来你的process的变化,很显然假设vol是常数,那么vol就不会随着BM的变化而变化)
但用其他模型都需要calibration,我不知道业界对比较复杂一些模型的容忍度多大。
。如果你觉得有实战需要可以从价格着手,然后求portfolio。最后做historical
simulation看效果啊。 |
