Review of statistical actuarial risk modelling
This survey treats the problem of ruin in a risk model when assets earn investment income. In addition to a general presentation of the problem, topics covered are a presentation of the relevant integro-differential equations, exact and numerical solutions, asymptotic results, bounds on the ruin probability and also the possibility of minimizing the ruin probability by investment and possibly reinsurance control. The main emphasis is on continuous time models, but discrete time models are also covered. A fairly extensive list of references is provided, particularly of papers published after For more references to papers published before that, the reader can consult . Source Probab.

Then, we show that the expected discounted penalty function the so-called Gerber—Shiu function can describe some risk indicators. Next, the dividend problem is discussed; more precisely, the approximated optimal dividend barrier is derived and other extended dividend strategies introduced. View via Publisher.

In such models key quantities of interest are the probability of ruin, distribution of surplus immediately prior to ruin and deficit at time of ruin. The model describes an insurance company who experiences two opposing cash flows: incoming cash premiums and outgoing claims. So for an insurer who starts with initial surplus x , . The central object of the model is to investigate the probability that the insurer's surplus level eventually falls below zero making the firm bankrupt. This quantity, called the probability of ultimate ruin, is defined as. In the case where the claim sizes are exponentially distributed, this simplifies to .
