报告摘要：

The current reinsurance market is extremely concentrated. The interconnections among reinsurers can be intertwined due to retrocession (i.e., reinsurance on reinsurance), causing reinsurance spirals. In this paper, we aim at a quantitative understanding of the role of retrocession in the health of reinsurers. To this end, we construct a static insurance–reinsurance network in which insurers purchase reinsurance and reinsurers also purchase reinsurance from each other. Through an asymptotic study of the number of defaulted reinsurers for the case of heavy-tailed primary losses, we discover that retrocession is a double-edged sword to the health of reinsurers.

This is joint work with Qihe Tang (UNSW Sydney).
