Abstract
In this paper, we study the optimal reinsurance policies as the result of a two-person cooperative game. We assume that both the insurer and the reinsurer are risk averse and expected-utility maximizers. In addition, we assume that they “agree to disagree” on the distribution of the underlying losses in the contract negotiation.
In our analysis, we consider two scenarios. In the first one, the reinsurance premium is fully negotiable, whereas in the second one, the premium is determined by the reinsurer using the expected value premium principle. For both scenarios, we first derive the set of Pareto-optimal reinsurance contracts and then identify the reinsurance contract corresponding to the Nash bargaining solution as well as that corresponding to the Kalai–Smorodinsky bargaining solution.
