Measuring the Extent of Coalition Formation in Group Decision Making
提出一种衡量群体决策中联盟形成程度的技术，通过分析N人博弈中的三人组和四人组博弈，适用于实验室实验和现实场景。
Abstract Many group decisions begin with small coalitions that recruit additional members until they satisfy a voting rule. This paper introduces a technique for measuring coalition formation in group decision making. The setting involves N players bargaining over the share distribution of an asset. The N ‐person game is analyzed as a set of triads, numerically equal to { N !/( N — 3)!}/3!. A three‐person game is presented to establish the context and to offer insights into the bargaining process. A four‐person game is also presented. The technique finds immediate application in controlled laboratory experiments but has further relevance for numerous real‐world contexts.
