Assessing Hail Risk for Property Insurers
Hail risk is among the most challenging perils to insure and property damage due to hailstones has been on the top of the list of annual claims for most non-life insurers. In this article, we present a simple yet flexible statistical model for insurers to assess and manage hail risks from two aspects: analyzing the insurance claims arrival pattern upon occurrence of a hailstorm and quantifying the subsequent financial impact of the hailstorm. We formulate the problem using a marked point process where the reporting of insurance claims due to a hailstorm is treated as recurrent events and the claim amounts are viewed as associated marks. Using a unique data that combines the exposure data from a major U.S. insurer and the radar data from a third-party vendor, we show the proposed method help improve predictive analytics for post hailstorm claims volume, arrival rate, and severity, and thus claim management decisions for the insurer.
