Many decisions in firms, organizations, and everyday life are not taken by individuals, but instead jointly by the members of a group. Examples include solving complex problems, devising strategies, compliance behavior in firms and organizations, and bargaining with other parties. This project is concerned with two main research questions regarding such informal group decision-making:1.) How does group size systematically affect the decision-making of groups? The vast majority of existing experimental studies on group decisions has focused on dyads or triads (i.e. groups of two and three members respectively) and the comparison with individual decision-making. Very little is known about the systematic effects when the group size is increased from two to three members or to even larger groups. This is, however, an empirically relevant case, since teams in firms and organizations are often larger than dyads or triads. Moreover, countervailing effects are expected from increasing the group size, such that it remains unclear what an optimal group size might be.2.) How are group decisions affected by the group gender composition? There exists an extensive experimental literature on how gender differences in preferences affect individual decision-making. However, there is no systematic evidence, whether such gender differences at the individual level are amplified or attenuated in group settings. By analyzing the effects of the gender composition in relatively large groups, we can shed light on this issue and contribute to the overall agenda towards a better understanding of gender differences in behavior.By running five laboratory experiments, each including informal group decision-making with groups of different size, we want to take a first step towards narrowing the literature gaps mentioned above. We thereby want to focus on three different areas of decision-making (intellective, judgmental and strategic) to provide evidence across different task types.

企业、组织和日常生活中的许多决定不是由个人做出的，而是由一个群体的成员共同做出的。例子包括解决复杂的问题，制定战略，在公司和组织中的合规行为，以及与其他各方讨价还价。这个项目涉及两个主要的研究问题，这种非正式群体决策：1。群体规模如何系统地影响群体的决策？绝大多数关于群体决策的现有实验研究都集中在二人或三人群体（即两人和三人群体）以及与个人决策的比较。当群体规模从两个成员增加到三个成员或甚至更大的群体时，对系统性影响知之甚少。然而，这是一个经验相关的案例，因为公司和组织中的团队通常比二人组或三人组更大。此外，预计增加集团规模会产生抵消效应，因此仍不清楚最佳集团规模可能是多少。群体决策如何受到群体性别构成的影响？有大量的实验文献研究偏好的性别差异如何影响个人决策。然而，没有系统的证据表明，这种性别差异在个人层面上是否在群体环境中被放大或减弱。通过分析性别构成在相对较大的群体中的影响，我们可以阐明这一问题，并有助于更好地理解行为中的性别差异。通过运行五个实验室实验，每个实验都包括不同规模群体的非正式群体决策，我们希望迈出缩小上述文献差距的第一步。因此，我们希望专注于三个不同的决策领域（决策，判断和战略），以提供跨不同任务类型的证据。
