报告简介
This talk discusses the second order asymptotic expansions for tail probabilities of discounted aggregate claims in two types of continuous-time renewal risk models with constant interest force，including continuous-time renewal risk models without and with by-claims. By firstly constructing the randomly weighted Kesten-type inequality for second order subexponential random variables, second order asymptotic formulae for these two types of continuous-time risk models are built. In comparison of the first order asymptotic formulae, our results are more superior and precise, which are demonstrated by some simple numerical studies.
