Union negotiations: Complement-associated games

Hamiache (2001) introduced the notion of associated consistency based on the idea of “individual negotiations”. In this article, “union negotiations” instead of “individual negotiations”, we introduce a new type of associated consistency based on the idea of “union negotiations”. Using the above types of associated consistency, we provide a new characterization of the equal allocation of non-separable costs (EANSC) value. We also prove that this approach cannot be applied to the Shapley value.
