Satoshi Nakada (School of Management, Department of Business Economics, Tokyo University of Science) – Coalition and Permission Structures in TU-games: Theoretical Insights and Application to Liability Situations

This paper introduces a new framework for TU-games that combines coalition and permission structures, accounting for hierarchical relationships among a priori unions. These structures naturally arise in liability situations involving a sequence of (distinct) parties. We propose a new allocation rule, the permission-Owen value, which merges the (conjunctive) permission value with the Owen value. We provide axiomatizations for this rule based on principles of monotonicity and fairness.
