Structured and Unstructured Valuation

Abstract

Economists can value things for cost-benefit analysis using either a structured or an unstructured approach. The first imposes some theoretical structure on the valuation; the second does not. This paper explains the difference between the approaches and examines the relative merits of each. Cost-benefit analysis may be aimed at finding what would be the best action, or alternatively at finding which action should be done in a democracy. The paper explains the difference, and argues that the appropriate aim is the first. Given that, it comes down in favour of the structured approach to valuation. As an example, it discusses different approaches to valuing life in economics.
