In simplified settings, optimal premium rules can be derived by classical approaches such as dynamic programming methods providing solutions to a Bellman equation. Realistic insurance settings involve features such as reporting/payment delays and fluctuations in the number of policyholders, partly in response to varying premium levels. In such settings, classical approaches are not applicable due to the size of the state space and lack of explicit expressions for transition probabilities.  

In this talk we will discuss how to design efficient algorithms in search of optimal premium rules in realistic insurance settings requiring reinforcement learning combined with function approximation. We illustrate the appropriateness of the approximate optimal premium rule compared with the true optimal premium rule in a simplified setting and further demonstrate that the approximate optimal premium rule outperforms benchmark rules in more realistic insurance settings where classical approaches fail.
