There is a natural tradeoﬀ between the beneﬁts of increasing the number of competitors in an insurance market and the drawback to the weakening of the law of large numbers due to the diminishing of average reserves. In this investigation we consider the possibility for optimal layers of reinsurance and retrocession in the design of the insurance industry. A general question which may be asked of all ﬁnancial institutions is what factors limit the number of layers of paper which can be constructed?
