Abstract

We study an optimal dynamic control problem of an insurance company whose wealth process is modeled by a jump diffusion. The company can purchase proportional reinsurance to reduce its risk level and invest all surplus in a risk free asset. The objective is to maximize the expected value of an exponential utility of the terminal wealth. We derive explicit optimal value function and find its associated reinsurance strategy.
