Abstract: In property insurance claims triage, insurers often use static information to assess the severity of a claim and to identify the subsequent actions. We hypothesize that the pattern of weather conditions throughout the course of a loss event is predictive of the insured losses, and hence appropriate use of weather dynamics improves the operation of insurers’ claim management. To test this hypothesis, we propose a deep learning method to incorporate dynamic weather information in the predictive modeling of the insured losses for reported claims. The proposed method features a hierarchical network architecture to address the challenges in claims triage due to the nature of weather dynamics. In the empirical analysis, we examine a portfolio of hail damage property insurance claims obtained from a major U.S. insurance carrier. When supplemented by dynamic weather information, the deep learning method exhibits substantial improvement in the hold-out predictive performance. We further design a cost-conscious decision strategy for triaging claims using the probabilistic forecasts of the insurance claim amounts. We show that leveraging weather dynamics in claims triage leads to a reduction of up to 9% and 6% in operational costs compared to when the triaging decision is based on forecasts without any weather information and with only static weather information, respectively.
