Abstract
This article deals with optimal stopping of Brownian Motion when the sampling cost is linear in time and the reward upon stopping is a non-decreasing function of the cumulative maximum. This can be viewed as pricing and management of a type of look-back American put option. The case of linear reward function was studied by Dubins & Schwarz [10].
Our treatment of the problem involves a stopped Brownian Motion formula by Taylor (see Taylor [18] and Williams [19]), first exit times by Brownian Motion from open intervals, processes with dichotomous transitions and the Azéma–Yor [2] stopping time.
