Actuaries Tackle Race in Insurance Pricing
The Casualty Actuarial Society (CAS) has developed a series of papers examining the issue of race and insurance pricing and seeking to contribute constructively to the policy discussion around it.
“Insurance pricing is a high-wire act,” CAS says. Actuaries have to quantify and differentiate among a massive variety of risk variables while avoiding unfair discrimination. “As regulation and society’s understanding of discrimination evolve, however, it is necessary for us to keep abreast of changes in the manner in which discrimination is defined and adjudicated.”
The CAS research has generated four papers – two published this week, two more to be published on March 31 – that define, quantify, and propose methods for addressing unfair discrimination where it is found to exist.
Confusion around insurance rating is understandable, given the complex predictive models being used today, which can lead to inappropriate comparisons and inaccurate conclusions. Algorithms and machine learning hold great promise for helping to ensure equitable pricing. However, research has shown these tools also can amplify biases that manage to creep into their programming.
Recent Colorado legislation requires insurers to show that their use of external data and complex algorithms don’t discriminate against protected classes, as well as other state and federal efforts to address perceived bias in pricing.
The actuarial discipline and the insurance industry are well positioned to continue helping policymakers and corporate decisionmakers understand these inequities and play a constructive role in the policy discussion.
The CAS papers published this week are:
Methods for Quantifying Discriminatory Effects on Protected Classes in Insurance
Approaches to Address Racial Bias in Financial Services: Lessons for the Insurance Industry
