Smooth inequality measurement: Approximation theorems

Author

Listed:
  • Le Breton, Michel
  • Peluso, Eugenio

Abstract

The main purpose of this paper is to prove that smoothness is not a restrictive assumption in inequality measurement as any inequality measure (preorder) can be approximated in a well defined sense by a smooth inequality measure (preorder).
