We demonstrate that only a change of sign in the utility function is sufficient for the commodity being a Giffen good as well an inferior good without any restriction imposed upon the parameters of the problemRobert Sproule (2022A) demuestra que la función de utilidad de Wold-Juréen se caracteriza por la Giffenity y bajo condiciones particulares el bien Giffen es un bien inferior.
