Panglossian Tendencies in Economics: The Case of Theoretical Welfare Economics

James Yunker

Journal of Economic Issues, 2009, vol. 43, issue 3, 759-778

Abstract: Some critics allege that many if not most economists are subject to "Panglossian tendencies" — that is, they are too quick to make excuses for apparently dysfunctional aspects of the status quo. This paper examines theoretical welfare economics as a possible exemplar of "Panglossian tendencies." A major focus is on the absence from both the pedagogic and the professional literatures of two key concepts bearing upon the evaluation of Pareto efficiency and social welfare maximization as competing criteria of economic policy analysis: the "isowelfare function" and the "supra-welfare region." These concepts are explicated herein using the familiar Edgeworth-Bowley box diagram illustrating the twoindividual, two-good pure exchange model. A higher level of awareness and appreciation among economists of these concepts might serve the beneficial purpose of downgrading the perceived significance of Pareto efficiency as an operational criterion of economic performance.
