Valuing non-marginal changes in mortality and morbidity risk.

Area of Science:

• Environmental Economics
• Health Economics
• Risk Assessment

Background:

• Stated-preference studies often struggle with scope sensitivity when estimating willingness-to-pay (WTP) for small health risk reductions.
• Small risk changes may not be perceived as meaningful by respondents, leading to inaccurate preference elicitation.
• Existing methods may not fully capture public valuation of significant health improvements.

Purpose of the Study:

• To propose a novel approach for estimating the value per statistical life (VSL) and value per statistical case (VSC).
• To address the limitations of scope sensitivity in traditional stated-preference valuation methods.
• To develop a de-biasing methodology for non-marginal risk reduction valuations.

Main Methods:

• Developing a valuation framework based on larger, percent-change risk reductions.
• Implementing a de-biasing technique to correct for biases introduced by non-marginal changes.
• Utilizing simulated stated-preference data for a proof of concept.

Main Results:

• The proposed method offers a way to estimate VSL and VSC using more comprehensible risk changes.
• The de-biasing methodology effectively addresses known biases associated with non-marginal risk valuations.
• Proof of concept demonstrates the feasibility and potential accuracy of the novel approach.

Conclusions:

• The novel approach enhances the reliability of VSL and VSC estimates by using larger risk reductions.
• This methodology provides a more robust tool for economic evaluation of health and safety policies.
• Accurate valuation of health risks is crucial for effective public policy and resource allocation.
