How does the law of large numbers benefit insurers?

The law of large numbers is a fundamental principle in insurance that allows insurers to predict future claims more accurately by analyzing historical claims data. This statistical concept states that as the number of similar exposure units increases, the actual loss experience will more closely approximate the expected loss experience.

By having a large sample size of policies and claims, insurers can establish patterns and averages, leading to improved predictability in their risk assessments. This means that they can estimate how much they need to set aside for future claims, determine premium pricing more effectively, and ultimately ensure that they can meet their future obligations to policyholders.

The other options present valid considerations for an insurer's business operations but do not directly relate to the core benefit of the law of large numbers. For example, while investment profits can be important, they are not the direct result of the law of large numbers. Similarly, operational cost reductions and equitable coverage for policyholders are influenced by various factors, including management practices and regulatory requirements, rather than solely by the statistical principles underlying the law of large numbers.
