What benefit does a larger insurance pool provide regarding risk premiums?

A larger insurance pool provides the benefit of more certainty about total losses within the pool due to the principle of risk diversification. When more individuals or entities are part of the insurance pool, the wide array of risks spreads out the potential for loss. By having a larger number of insured members, the insurer can better estimate the total expected losses based on historical data and statistical analysis.

This certainty allows insurers to set premiums more accurately, reducing the risk of underpricing or overpricing insurance contracts. Essentially, with many policyholders contributing premiums and a variety of risks covered, the unpredictable nature of claims becomes more manageable, leading to more stable and predictable financial outcomes for the insurer.

The size of the pool helps to buffer against extreme losses that might affect a smaller group, as the law of large numbers suggests that with more data points, the overall expected loss becomes clearer. This understanding translates into potentially lower premiums for everyone involved, as the insurer can rely on statistical evidence to define risk more effectively.
