Abstract
In this paper, a discrete-time risk model with random income and a constant dividend barrier is considered. Under such a dividend policy, once the insurer’s reserve hits the level b b > 0 , the excess of the reserve over b is paid off as dividends. We derive a homogeneous difference equation for the expected present value of dividend payments. Corresponding solution procedures for the difference equation are invested. Finally, we give a numerical example to illustrate the applicability of the results obtained.
Highlights
Many authors focus their research interests on discrete-time risk models, which can be used as an approximation to continuous time models
Discrete-time risk models with dependent structure have received increasing attention, and the readers are referred to Liu and Bao [2] for the related studies on different kinds of dependent models
We introduce a dividend policy to the company that a certain amount of dividends will be paid to the policyholder instantly, as long as the surplus of the company at time k is higher than a constant dividend barrier b(b > 0)
Summary
Many authors focus their research interests on discrete-time risk models, which can be used as an approximation to continuous time models. For the compound binomial risk model with possible delay of claims, Xie and Zou [5] investigate the expected present value of total dividends under stochastic interest rates. We propose a discrete-time risk model with random income and a constant dividend barrier. We introduce a dividend policy to the company that a certain amount of dividends will be paid to the policyholder instantly, as long as the surplus of the company at time k is higher than a constant dividend barrier b(b > 0) It implies that the dividend payments will only possibly occur at the beginning of each period, right after receiving the premium payment.
