A Markov-modulated jump-diffusion risk model with randomized observation periods and threshold dividend strategy

This paper considers a Markov-modulated jump-diffusion risk model with randomized observation periods and threshold dividend. A second order integro-differential system of equations that characterizes the expected discounted dividend payments is obtained. As a closed-form solution does not exist, a numerical procedure based on the sinc function approximation through a collocation method is proposed. Finally, an example illustrating the procedure is presented.
