Jia Niannian, Xia Yunfan, Ruin Probabilities of Double Compound Poisson Risk Model under Proportional Reinsurance and Interest Force, Journal of Modern Mathematics and Statistics, Volume 6,Issue 2, 2012, Pages 10-13, ISSN 1994-5388, jmmstat.2012.10.13, (https://makhillpublications.co/view-article.php?doi=jmmstat.2012.10.13) Abstract: The researchers introduced interest force and reduced the risk of the insurance company with the proportional reinsurance under double compound Poisson risk model. Differential-Integral equations of ruin probabilities in finite and infinite time were provided. These conclusions have theoretical significance for the insurance company measuring ruin risk.
