Claims manipulations discriminate between egalitarian rules Yin, Xiuxia Calleja, Pere Izquierdo Aznar, Josep Maria Axiomes Fusió d'empreses Axioms Consolidation and merger of corporations We provide axiomatic characterizations of the constrained equal awards and constrainedequal losses rules by imposing immunity principles such as non-manipulability via merging(splitting) and strong non-manipulability via merging (splitting). 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. 2026-01-20T14:26:09Z 2026-01-20T14:26:09Z 2026-01-20T14:26:10Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 0040-5833 https://hdl.handle.net/2445/225830 763952 eng Versió postprint del document publicat a: https://doi.org/10.1007/s11238-025-10096-2 Theory and Decision, 2025 https://doi.org/10.1007/s11238-025-10096-2 (c) Springer Verlag, 2025 info:eu-repo/semantics/openAccess 1 p. application/pdf Springer Verlag Articles publicats en revistes (Matemàtica Econòmica, Financera i Actuarial)
