Some remarks on Brownian motion with drift

Author:

Doney R. A.,Grey D. R.

Abstract

Certain limit theorems due to Berman involve the total time spent by Brownian motion with positive drift below an independent exponentially distributed level. Imhof has calculated the density function and shown that this random variable has two interesting probabilistic properties. We give sample path arguments which explain these two facts.
