A Remark on Admissible Transformations for Interpersonally Comparable Utilities.

In this paper, the authors provide a characterization of the set of admissible transformations of utility profiles if it is assumed that the individual utilities are ordinally measurable and interpersonally comparable. Whereas earlier contributions (implicitly) assume that all individual utility functions have the same image, their results apply to arbitrary utility profiles. Furthermore, the authors discuss an example that demonstrates the sensitivity of some results in this area with respect to the assumptions that are made concerning the images of the individual utility functions.
