Description:
This paper presents a general model of cash management, viewed as an impulse control problem for a stochastic money flow process. Generalizing classical approaches, we represent this process by a superposition of a Brownian motion and a compound Poisson process, controlled by two-sided target-trigger policies. For phase-type distributions for the upward and downward jumps we determine all pertinent cost functionals explicitly. Moreover, the controlled process is studied in steady state. The closed-form results can be used to determine optimal values for the target and trigger values numerically.
