Bi-Polarization Comparisons

  • Jean-Yves Duclos
  • Damien Echevin

This note provides simple tests for first-order bi-polarization orderings of distributions of living standards. In doing so, the paper also offers an ethical basis and an interpretation for the common use of some simple measures of distances from the median. Illustrations using Luxembourg Income Study data show that several countries can be ranked by such tests of bi-polarization.
