Research paper thumbnail of Continuous representability of homothetic preferences by means of homogeneous utility functions

Journal of Mathematical Economics, 2000

Our approach is based on the solution of the functional equation of homotheticity. q 2000 Elsevier Science S.A. All rights reserved. JEL classification: C60; D50

Provided that an agent's binary relation is acyclic, this is a selection of its maximal elements that can always be done when the set of alternatives is finite. In the case of semiorders, proceeding in this way is the same as using Luce's selected maximals.
