Are Two Better Than One? Bargaining Behavior and Outcomes in an Asymmetrical Power Relationship
研究在不对称权力关系中，讨价还价单位规模（一人或两人）如何影响经济绩效、沟通风格和事后态度，发现两人群体会放大权力操纵的效果。
Many consumer transactions are characterized by bargaining between parties holding unequal power positions. The group polarization hypothesis suggests that the effects of group size will differ for high- and low-power bargainers. Accordingly, power position and size of bargaining unit (one, two) were manipulated in a threat-vulnerable 2 × 2 game. Factor effects on economic performance, communication style, and post-bargaining attitudes were examined at the unit and system levels. Supporting the group polarization hypothesis, two-person groups tend to magnify the power manipulation—i.e., group size interacts with power position on post-bargaining attitudes and system performance.
