TY - JOUR T1 - On the Asymptotic Expansions for the Expected Value and Variance of the Reinsurance Surplus Process AU - Bayramov, Veli AU - Abdullayeva, Afaq AU - Aliyev, Rovshan PY - 2020 DA - December Y2 - 2020 JF - Conference Proceedings of Science and Technology PB - Murat TOSUN WT - DergiPark SN - 2651-544X SP - 207 EP - 214 VL - 3 IS - 1 LA - en AB - In this paper, we consider the reinsurance surplus process. Depending on the type of the reinsurance we obtain formulas for the distribution functions and moments of claims in reinsurance surplus process, then using these moments we give the asymptotic results for the mathematical expectation and variance in each type of the reinsurance. Then we give numerical examples to compare the values of mathematical expectation and variance when there is no reinsurance and when the insurer effects reinsurance.
