Abstract
Inspirándose en los fundamentos de Shapley, Myerson (1977) propuso una solución única para juegos en forma de función de partición caracterizados por tres axiomas: linealidad, simetría y el axioma del portador. Esta investigación tiene como objetivo determinar si se puede llegar a una caracterización alternativa mediante la inclusión de un axioma de nulidad. Hasta donde sabemos, no existe tal caracterización en la literatura actual. Se presenta una propuesta para una definición de jugador nulo, revelando que la caracterización derivada no es única. En cambio, se presenta una familia de soluciones parametrizadas, demostrando la diversidad de reparticiones potenciales en este contexto.
Drawing inspiration from Shapley’s foundations, Myerson (1977) proposed a unique solution for games in partition function form characterized by three axioms: linearity, symmetry, and the carrier axiom. This research aimed to determine if an alternative characterization can be reached by including a nullity axiom. As far as we know, there is not such characterization in the current literature. A proposal for a null player definition is introduced, revealing that the derived characterization is not unique. Instead, a family of parameterized solutions is presented, demonstrating the diversity of potential outcomes in this context.
