This study introduces a unified approach to valuing longevity gains from public policies. It integrates health preferences to consistently estimate the value of statistical life (VSL), value of statistical life year (VSLY), and willingness-to-pay for a quality-adjusted life year (WTP-QALY).
Area of Science:
- Health Economics
- Public Policy Analysis
- Biostatistics
Background:
- Public policies significantly influence individual mortality risk.
- Traditional monetization of longevity gains uses distinct metrics: VSL, VSLY, and WTP-QALY.
- Existing methods for valuing longevity gains lack a unified framework.
Purpose of the Study:
- To develop a unified approach for monetizing longevity gains from public policies.
- To integrate health and longevity preferences for consistent valuation.
- To enable the estimation of VSL, VSLY, and WTP-QALY within a single framework.
Main Methods:
- Adopting life expectancy gains as the unifying metric.
- Incorporating preference-based information on health and longevity.
- Developing a framework to conceptually link individual-level valuation measures.
Main Results:
- The proposed approach generates three conceptually linked measures: VSL, VSLY, and WTP-QALY.
- Explicit integration of health preferences allows for WTP-QALY estimation alongside VSL and VSLY.
- The framework offers advantages over existing direct and modeling methods.
Conclusions:
- The proposed framework facilitates consistent decision-making across diverse policy domains.
- It allows for ex ante regulatory assessment while respecting varied empirical estimation practices.
- This unified approach enhances the coherence of valuing longevity gains in public policy.
