We study the Markov decision processes under the average-value-at-risk criterion.The state space and the action space are Borel spaces,the costs are admitted to be unbounded from above,and the discount factors are sta...

VaR Criteria for optimal limited changeloss and truncated change-loss reinsurance
《Frontiers of Mathematics in China》2013年第3期583-608,共26页Xiaojing MA Lan WU 
Reinsurance can provide an effective way for insurer to manage its risk exposure. In this paper, we further analyze the optimal reinsurance models recently proposed by J. Cai and K. S. Tan [Astin Bulletin, 2007, 37(...
