The Underwriting Cycle and the Risk Manager
研究了财产与责任保险行业的承保周期，提出一种创新周期回归算法来判断周期是否存在，发现该行业存在六年承保周期。
This paper examined the property and liability insurance industry's underwriting cycle and proposes a methodology for determining if a cycle exists. The methodology uses an innovative cycle regression algorithm to capture the behavior of the stochastic processes which generate combined loss and expense ratios. The conclusions indicate that a six year underwriting cycle does exist for the property and liability insurance industry.
