Using risk assessment, benefit-cost analysis, and real options to implement a precautionary principle

Area of Science:

• Environmental Science
• Public Health
• Economics

Background:

• Risk assessment is standard for environmental and public health.
• Benefit-cost analysis often lacks transparent variability evaluation.
• The Precautionary Principle is proposed by advocates but vaguely framed.

Purpose of the Study:

• To combine risk assessment techniques with benefit-cost analysis.
• To develop a quantifiable, case-specific, and risk-dependent "precautionary" threshold.
• To offer an alternative to standard benefit-cost approaches for decision-making under uncertainty.

Main Methods:

• Integrating quantitative risk assessment for variability characterization.
• Applying benefit-cost analysis frameworks.
• Developing decision-making criteria under uncertainty and irreversibility.

Main Results:

• A novel framework combining risk assessment and benefit-cost analysis was developed.
• A quantifiable, risk-dependent "precautionary" threshold for action was established.
• The approach offers improved transparency in evaluating variability.

Conclusions:

• The proposed method provides a more robust and transparent approach to environmental and public health decision-making.
• This framework can be applied to regulations like the Clean Air Act and genetically modified corn.
• It offers a quantifiable alternative to vague "Precautionary Principle" criteria.
