Summary

The α-Fair Individual Solvent Premium (α-FISP) framework is proposed to address the complex tension between actuarial and solidarity fairness in insurance pricing. This framework formulates the pricing problem as a constrained optimization task, where actuarially fair premiums are adjusted based on budget constraints for cross-subsidization within each risk class. It yields a family of solutions parameterized by α, creating a continuum from purely actuarial to purely solidarity-based pricing. The α-FISP framework guarantees solvency, is computationally tractable, and aligns well with heterogeneous U.S. state-level regulatory requirements for fairness. This allows decision-makers to select an appropriate operating point along the fairness spectrum.

Key takeaway

For actuaries or policy makers developing insurance pricing models, the α-FISP framework offers a structured approach to navigate the inherent trade-off between actuarial and solidarity fairness. You can leverage its parameterized continuum to explicitly define and implement your desired balance, ensuring both profitability and social responsibility. Consider using this optimization-based method to align your pricing strategies with specific regulatory mandates and societal expectations for equitable risk pooling.

Key insights

The α-FISP framework offers a continuum to balance actuarial and solidarity fairness in insurance pricing while ensuring solvency.

Principles

• Insurance pricing balances actuarial fairness with solidarity fairness.
• Solvency is a non-negotiable requirement for insurance operations.
• Granular data intensifies regulatory pressure on vulnerable groups.

Method

The framework uses constrained optimization to adjust actuarially fair premiums, applying budget constraints on cross-subsidization within risk classes to generate an α-parameterized fairness continuum.

In practice

• Select an optimal operating point on the fairness spectrum.
• Align pricing models with diverse state-level fairness regulations.
