In this paper we study the relationship between inequality and social instability. While the argument that inequality can be damaging for the cohesion of a society is old, the empirical evidence is mixed. We use a novel approach to isolate the causal relationship running from inequality to...

We study the relationship between inequality and social instability. While the argument that inequality can be damaging for the cohesion of a society is well established, the empirical evidence is mixed. We use a novel approach to isolate the causal relationship running from inequality to social...

We study a model of collective decision making with endogenous information collection.Agents collect information about the consequences of a project, communicate, and then vote onthe project. We examine under what conditions communication may increase the probability thatgood decisions are made....

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...

This paper studies the assignment of decision makers to two committees that make decisions by a simple majority rule. There is an even number of decision makers at each of the various skill levels and each committee has an odd number of members. Surprisingly, even with the symmetric assumptions...

This paper studies the vulnerability of the pivotal mechanism with respect to manipulation by groups. In a lab experiment, groups decide on the implementation of various alternatives, some of which imply opposite interests for the two subgroups. We investigate the occurrence of tacit and...

We study dispute resolution in the compromise model of Börgers and Postl (2009), which provides an alternative framework for analyzing the real-world procedure of tri-offer arbitration studied in Ashenfelter et al. (1992). Two parties involved in a dispute have to choose between their...

Given an argumentation framework and a group of agents, the individuals may have divergent opinions on the status of the arguments. If the group needs to reach a common po- sition on the argumentation framework, the question is how the individual evaluations can be mapped into a collective one....
