Shared consumer decisions, particularly those made with a relationship partner, can be very different from decisions that are made alone. Across multiple studies, we investigate how shared consumer decision making affects perceptions of power and relationship satisfaction. We integrate two streams of research to create a novel theory about consumer decision making and perceived power. Specifically, we suggest that shared consumer decision making combines two necessary components of power—an individual's influence over and a partner's engagement in the decision—and that these combined components drive power perceptions. In other words, individuals who relinquish some control and make a decision with their partner, ironically, perceive having greater power than if they had made the decision alone. We further find that shared decision making and greater perceived power lead to greater satisfaction with the relationship in which the decisions are made. By focusing on consumer decision making within relationships, the current research contributes to the literatures on decision making, social influences in consumer behavior, close relationships, consumer well-being, and power.

更好地共同决策：共同的消费者决策、感知权力和关系满意度

共同的消费者决定，尤其是与关系伙伴共同做出的决定，可能与单独做出的决定大不相同。在多项研究中，我们调查了共同的消费者决策如何影响对权力和关系满意度的感知。我们整合了两个研究流，以创建一个关于消费者决策和感知能力的新理论。具体来说，我们建议共同的消费者决策结合了权力的两个必要组成部分——个人对决策的影响和合作伙伴对决策的参与——并且这些结合的组成部分驱动权力感知。换句话说，具有讽刺意味的是，放弃一些控制权并与伴侣一起做决定的人会认为自己比单独做决定拥有更大的权力。我们进一步发现，共同决策和更大的感知权力会导致对决策关系的更大满意度。通过关注关系中的消费者决策，当前的研究有助于有关决策、消费者行为中的社会影响、亲密关系、消费者福祉和权力的文献。
