Document Details : Title: Average Value-at-Risk Minimizing Reinsurance under Wang's Premium Principle with Constraints Author(s): CHEUNG, K.C. , LIU, F. , YAM, S.C.P. Journal: ASTIN Bulletin Volume: 42 Issue: 2 Date: 2012 Pages: 575-600 DOI: 10.2143/AST.42.2.2182809 Abstract : In the present work, we study the optimal reinsurance decision problem in which the Average Value-at-Risk of the retained loss is minimized under Wang’s premium principle and is also subject to either (1) a budget constraint on reinsurance premium, or (2) a reinsurer’s probabilistic benchmark constraint of his potential loss. We show that the optimal reinsurance is a single-insurance layer under Constraint (1), and a cap insurance or a double-insurance layer under Constraint (2); moreover, under Constraint (2), we further establish that under most common circumstances (see Remark after Theorem 3), a cap insurance will suffice to be optimal. Finally, some numerical illustrations will be provided. |
