New Derivation of Samuelson’s (1947) Utility Possibility Curve by Analogy of Konar’s (2006) Diagram for the Contribution to Economic(s) Education

Like the “production possibility curve” (PPC) of Stolper and Samuelson (1941), the “utility possibility curve” (UPC) of Samuelson (1947), is a staple tool in the literature of economic(s) education at the lower and higher levels. Among the tally of methods of the derivation of the PPC (e.g. Black 1957, Worswick 1957, Savosnick 1958, Ferguson 1962, Travis 1964, Houck 1966, Melvin 1971 and Konar 2006), the “new password” is Konar's (2006) diagrammatic method. The “newness” of the “password” lies only in its maximum simplicity. The previous methods can be treated as “easier ways” to “complicate” its derivation. But the previous methods, in which the framework of “Edgeworth-Box” is embedded, have acquired widespread acceptance and relentless success. Since the UPC is very similar in concept to the PPC, similar diagrammatic framework of Konar (2006), has been used in this article, instead of conventional Edgeworth-Box framework, for the derivation of Samuelson's (1947) UPC
