Abstract: Formulas for level crossing probabilities, ladder height distributions and related
characteristics of a general class of processes with stationary bounded variations and
continuous decreasing components are derived under certain mild conditions. Results for a
risk process with a constant premium rate and with a claim process generated by a
stationary marked point process are generalized to the case where the premium
rate itself can be a stochastic process and the claim arrival process can have both
jumps and continuous components. The case of infinitely many jumps in finite
intervals is not excluded. The main tool for investigating this more general class of
stochastic models in an exchange formula for Palm probabilities of stationary random
measures. Our results can be used to derive a formula for the ascending ladder
height distribution of the time-stationary workload process in single-server queues.
