具有多项式报酬的Levy过程的最优停止

Optimal stopping for Levy processes with polynomial rewards

Ernesto Mordecki, Yuliya Mishura

摘要:

当具有多项式报酬函数的Levy过程的无穷时域最优停止问题的解是单侧的时,利用过程的整体上确界给出了该问题的显式解.结果是通过推广已知的结果与问题的平均函数。在多项式奖励的情况下,可以直接计算该平均函数。为了说明这一结果,一般的二次和三次多项式的例子进行了讨论的情况下,过程是布朗运动,并解决了最优停止问题的四次多项式和寇氏过程。

英文摘要:

Explicit solution of an infinite horizon optimal stopping problem for a Levy processes with a polynomial reward function is given, in terms of the overall supremum of the process, when the solution of the problem is one-sided. The results are obtained via the generalization of known results about the averaging function associated with the problem. This averaging function can be directly computed in case of polynomial rewards. To illustrate this result, examples for general quadratic and cubic polynomials are discussed in case the process is Brownian motion, and the optimal stopping problem for a quartic polynomial and a Kou's process is solved.
