We study the effect of public information on collective decision-making in committees, where members can have both common and conflicting interests. In the presence of public information, the simple and efficient vote-your-signal strategy profile no longer constitutes an equilibrium under the...

We study the effect of public information on collective decision-making in a committee with members of both common and conflicting interests. We show that the set of preferences that allow for the existence of an informative voting equilibrium can be heavily restricted by the presence of a...

This paper examines whether an institution has a differing impact on cooperation if it is introduced by a representative of the affected parties rather than exogenously imposed. The experimental design is able to control for selection effects arising from the democratic policy choice. I find...

Economic small group research points to groups as more rational decision-makers in numerous economic situations. However, no attempts have been made to investigate whether groups are affected similarly by behavioral biases that are pervasive for individuals. If groups were also able to more...

The recent literature on individual and group choices over risk has led to different results. In some studies under unanimity, groups were found to be less risk averse than individuals, while those under majority did not highlight significant differences. However, both the types of studies...

Challenges in global politics like climate change, maritime piracy and fighting highly contagious diseases concern global public goods. The related policy decisions are mostly made by teams. In contrast, economic models of global public goods typically assume a single rational decision-maker. We...

Background: Individual decision-making largely influences the effectiveness of decisions and benefits of investments. Methods: In this article, a consensus model for group decision-making (GDM), based on the analytic hierarchy process (AHP), is developed to gather group ideas and analyze the...

We study experimentally the effectiveness of communication in common value committees exhibiting publicly known heterogeneous biases. We test models assuming respectively self-interested and strategic-, joint payoff-maximizing- and cognitively heterogeneous agents. These predict varying degrees...

This paper analyzes responsibility attributions for outcomes of collective decision making processes. In particular, we ask if decision makers are blamed for being pivotal if they implement an unpopular outcome in a sequential voting process. We conduct an experimental voting game in which...

I study the distribution of voting power between different decision-makers in French river basin committees over the period 1987-2007. To do so, in the first part of the paper, I apply different power measures traditionally used in the literature as well as some other ones lesser known in this...

Kooperation stellt einen wichtigen Faktor beim Erreichen ökonomischer Ziele dar. Dient Kooperation den eigenen Interessen, lässt dies eine relativ triviale Erklärung kooperativer Handlungsweisen anhand von Eigennutz zu. Gilt dies jedoch nicht, ist eine genauere Analyse kooperativer...

It is still an open question when groups perform better than individuals in intellective tasks. We report that in an Acquiring a Company game, what prevailed when there was disagreement among group members was the median proposal and not the best proposal. This aggregation rule explains why...

A burgeoning problem facing organizations is the loss of workgroup productivity due to cyberloafing. The current paper examines how changes in the decision-making rights about what workgroup members can do on the job affect cyberloafing and subsequent work productivity. We compare two different...

We investigate the potential of transparency to influence committee decision-making. We present a model in which career concerned committee members receive private information of different type-dependent accuracy, deliberate and vote. We study three levels of transparency under which career...

This paper experimentally studies the disposition effects of teams and individuals. The disposition effect describes the phenomenon that investors are reluctant to realize losses, whereas winners are sold too early. Our experiments compare the investments of two-person teams to a setting where...

Failure to express minority views may distort the behavior of company boards, committees, juries, and other decision-making bodies. Devising a new experimental procedure to measure such conformity in a judgment task, we compare the degree of conformity in groups with varying gender composition....

Maintenance has been acknowledged by industrial management as a significant influencing factor of plant performance. Effective plant maintenance can be realized by developing a proper maintenance strategy. However, selecting an appropriate maintenance strategy is difficult because maintenance is...
