Abstract
In this work, we study the optimization problem confronted by an insurance firm whose management can control its cash-balance dynamics by adjusting the under- lying premium rate. The firm’s objective is to minimize the total deviation of its cash-balance process to some pre-set target levels by selecting an appropriate pre- mium policy. We study the problem in a general framework and make two interesting inclusions; Firstly, we introduce the aspect of time delay to the system; and we replace the stan- dard expected additive utility function with a Stochastic differential utility (SDU). We reformulate the problem and obtain a semi coupled Forward-Backward Stochas- tic Differential Equation and prove that this forward-backward system admits a unique solution. The Sufficient Maximum Principle for an optimal control of such a system is established and we conclude with a case study of three particular cases which fit into our general model. Some concluding remarks are also given.
