We show that the constrainedequal awards rule is the unique rule satisfying strong non-manipulability via mergingand contraction independence. Replacing contraction independence with the weaker conditionof independence of redundant claims yields a new characterization. Moreover, strongnon-manipulability via merging in the above two axiomatizations can be substituted byconsistency and non-manipulability via merging. By duality, we achieve parallel characterizationsof the constrained equal losses rule.
