Well-Being Analysis vs. Cost-Benefit Analysis
Cost-benefit analysis is the primary tool used by policymakers to inform administrative decisionmaking. Yet its methodology of converting preferences (often hypothetical ones) into dollar figures, then using those dollar figures as proxies for quality of life, creates systemic errors so large as to deprive the tool of value. These problems have been lamented by many scholars, and recent calls have gone out from world leaders and prominent economists to find an alternative analytical device that would measure quality of life more directly. This Article proposes well-being analysis (WBA) as that alternative. Relying on data from the field of hedonic psychology that tracks people’s actual experience of life — data that has consistently survived scrutiny by passing the social science tests of reliability and validity — WBA is able to provide the same policy guidance as CBA without CBA’s distortionary conversion of preferences to dollars. We show how WBA can be implemented, and we catalog exhaustively its superiority over CBA. In light of this comparison, we conclude that there is no reason for CBA to continue as the decisionmaking tool of choice for administrative regulation.
