selection mechanisms in group decision-making. In a setting where all members of a group get the same payoff based on the group … leader's decision of how much risk to take, we study the effects of two treatment variables: (1) whether group members can …'s decision: the communicated preferences have a significant effect on the actual group decision only when the leader is appointed …

This paper studies experimentally when and how ideological motives shape outcomes in group decision-making scenarios …. Groups play a repeated coordination game in which they can agree on a payoff-dominant or a payoff-dominated but ideologically … preferred outcome, or disagree and forego all payoffs. We find that groups which disagree initially are more likely to end up …

Using an experiment with incentivized decisions of groups in the economics laboratory, I investigate the effect of … significantly higher risk taking by groups as compared to individuals. Furthermore, the only dimension of diversity with an effect …

a public good setting and how this affects the other group members. We compare an exogenous and an endogenous decision …. Our results reveal that both - the decision to extend a contract and the decision mechanism itself - affect not only the … group after the decision has been made. …

This paper experimentally studies the disposition effects of teams and individuals. The disposition effect describes … the investments of two-person teams to a setting where investors trade alone. We find that subjects investing jointly … exhibit more pronounced disposition effects than individuals. A closer look reveals that investor teams hardly realize losses …

We report that in an … best proposal. This aggregation rule explains why groups underperformed with respect to a "truth wins" benchmark and why …

Our study compares individual and team bidding in standard auction formats: first-price, second-price and ascending … teams in first-price auctions and deviate more from bidding their own value in second-price auctions.

Team decision-making prevails in modern organizations. Teams often need to decide whether to delegate or make a … decision right, which may distort the choice between delegating a decision or not. Here we examine experimentally whether teams … uncover an important heterogeneity within teams. Teams with a smooth decision making process have much lower intrinsic values …
