最优双停时

Optimal double stopping time

Magdalena Kobylanski, Marie-Claire Quenez, Elisabeth Rouy-Mironescu

摘要:

我们考虑由$v(S)=\esssup\{E[ψ(τ_1, τ_2) | \F_S], τ_1, τ_2 \geq S \}$定义的每个停时$S$的最优双停时问题。在最优单停时问题的基础上,研究了最优停时的存在性,并给出了一种计算方法。关键点是构造{ \em新奖励} $ϕ$,使得值函数$v(S)$满足$v(S)=\esssup\{E[ϕ(τ) | \F_S], τ\geq S \}$。最后,我们给出了一个具有双倍执行时间的美式期权的例子。

英文摘要:

We consider the optimal double stopping time problem defined for each stopping time $S$ by $v(S)=\esssup\{E[ψ(τ_1, τ_2) | \F_S], τ_1, τ_2 \geq S \}$. Following the optimal one stopping time problem, we study the existence of optimal stopping times and give a method to compute them. The key point is the construction of a {\em new reward} $ϕ$ such that the value function $v(S)$ satisfies $v(S)=\esssup\{E[ϕ(τ) | \F_S], τ\geq S \}$. Finally, we give an example of an american option with double exercise time.
