Trade-offs and the precautionary principle: A lexicographic utility approach

Area of Science:

• Decision theory
• Risk management
• Environmental policy

Background:

• The precautionary principle (PP) faces criticism for its inability to guide resource allocation across diverse risks.
• Existing frameworks struggle to balance catastrophic versus non-catastrophic risks and inter-catastrophe trade-offs.

Purpose of the Study:

• To develop a formal interpretation of the precautionary principle (PP) that addresses resource allocation challenges.
• To provide a framework for maximizing lexical utility under conditions of multiple catastrophic risks.
• To demonstrate how this framework can guide resource distribution between disaster prevention and other societal needs.

Main Methods:

• Extension of a formal interpretation of the precautionary principle (PP).
• Utilizing a lexical utility framework to model decision-making under risk.
• Mathematical proofs to determine optimal resource distribution strategies.

Main Results:

• The proposed lexical utility interpretation of PP offers a method for resource distribution across multiple catastrophic risks.
• The framework proves which resource distributions maximize lexical utility under various assumptions.
• Demonstrates the capacity of the lexical utility interpretation of PP to recommend balanced resource allocation.

Conclusions:

• A formal lexical utility interpretation of the precautionary principle (PP) can resolve challenges in allocating resources for catastrophic risks.
• This approach provides a rational basis for prioritizing and distributing resources to mitigate diverse threats.
• The framework supports balanced investment in disaster prevention alongside other essential societal concerns.
