On Small Coalitions, Hierarchic Decision Making and Collective Competence

  • Sven Berg


This paper discusses the reliability of group judgment in the context of decentralized decision making systems (indirect voting). Composite majority functions are introduced and their properties studied along with coalition structures. The effects on collective competence of grouping individuals in a hierarchic system are examined. Formulas are developed to measure the loss (or gain) in judgmental competence.
