ItemOptimal Dividends under a Ruin ProbabilityConstraintDickson, David CM ; Drekic, Steve ( 2005-10)We consider a classical surplus process modified by the paymentof dividends when the insurer’s surplus exceeds a threshold. We use aprobabilistic argument to obtain general expressions for the expected present value of dividend payments, and show how these expressions can be applied for certain individual claim amount distributions. We then consider the question of maximising the expected present valueof dividend payments subject to a constraint on the insurer’s ruin probability.
ItemRuin Probabilities with a Markov Chain Interest ModelCai, Jun ; Dickson, David C. M. ( 2002-08)Ruin probabilities in two generalized discrete time risk processes with a Markov chain interest model are studied. Recursive and integrat equations for the ruin probabilities are given. Generalized Lundberg inequalities for the ruin probabilities are derived both by inductive and martingale approaches. The relationships between these inequalities are discussed. A numerical example is given to illustrate these results.
