q-fixed majority efficiency of committee scoring rules

Year: 2025

Type: article

Abstract: This paper introduces the q -fixed majority property for committee selection rules, which extends the traditional fixed majority principle to a flexible framework. We examine conditions under which the committee scoring rules satisfy the q -fixed majority property. Focusing on (weakly) separable rules, we find that the Bloc rule is the only which satisfies it for all q > 1 / 2 . In addition, the q -bottom majority property is introduced, highlighting conditions under which committees can be excluded based on voter consensus.
