Fairness in Economics: An Overview and a Special Application to Water Systems

This paper provides an overview of the evolving role of fairness in economic thought and discusses how it is related to contemporary policy design. We first discuss the conceptual foundations of fairness in economics by discussing the notions of equity, justice, and efficiency and highlighting they're between differences. Acknowledging the tradeoff between fairness and allocative efficiency we discuss how the economics discipline has addressed this challenge and has provided tools that facilitate prioritizing and decision making. We then study how we can measure and capture fairness in a way that will allow us to quantify the concept and include it in our theoretical and empirical models as well as in experimental settings. Third, we highlight the policy implications associated with fairness literature. Last, the paper applies these theoretical insights to the governance of water resources-a sector where distributional conflicts, environmental constraints, and institutional complexity intersect. Relying on interdisciplinary research and policy examples, we uncover how fairness principles can shape water allocation, access, and pricing. The paper overall argues that accounting for fairness more explicitly into economic analysis can enrich both normative and practical policy frameworks, especially in resource-scarce contexts.
