Infinite Time Exact Ruin Probabilities in a Stochastic Economic Environment

This article investigates the infinite-time ruin probabilities in a discrete-time stochastic economic environment platform under the assumption that the insurance risk-the total net loss within one time period is absolute-repeatedly-varying or suddenly-varying tailed, a different accurate estimates for the ruin probabilities are derived. In particular, some estimates found are standardized with respect to the time horizon, and so utilize in the case of infinite-time ruin.
