In the study of Giffen behavior or "Giffenity", there remains a paradox. On the one hand, the Wold-Juréen (1953) utility function has been touted as the progenitor of a multi-decade search for those two-good, particular utility functions, which exhibit Giffenity. On the other hand, there is no...

In the study of Giffen behavior or "Giffenity", there remains a paradox. On one hand, the Wold-Juréen (Demand analysis: A study in Econometrics, 1953) utility function has been touted as the progenitor of a multi-decade search for those two-good, particular utility functions, which exhibit...

Presently, it is widely accepted that the particular utility function first reported by Wold and Juréen (1953), and later by Weber (1997), is capable of generating a Giffen good. This note challenges this view by showing that this Wold-Juréen (1953) utility function is not well-behaved, and...
