Benefit-cost analysis (BCA) is frequently applied to decisions involving public safety which requires analyzing risk and assessing options to manage risks. Principles and standards may assist analysts, decision-makers, and the public in developing and interpreting such BCAs. Principles and standards at best represent commonly held views among a community of practice. Such views are continually evolving with advances in the field. This paper presents a modularized format towards principles and standards that may assist in focusing discussion and decisions about whether such proposals actually reflect principles and standards within the benefit-cost analysis community of practice. Among topics covered are welfare measures, benefit or cost transfer, and valuing uncertain outcomes.
