Group identification refers to the problem of classifying individuals into groups (e.g., racial or ethnic classification). We consider a multinary group identification model where memberships to three or more groups are simultaneously determined based on individual opinions on who belong to what...

Zur Manipulierbarkeit der Allokation öffentlicher Güter: Theoretische Analyse und Simulationsergebnisse

Lindner, Tobias - 2011

Die vorliegende Arbeit untersucht die Aufteilung eines Budgets auf mehrere öffentliche Güter mittels einer Abstimmung. Hierzu betrachten wir Abstimmungsregeln, unter denen jeder Agent eine Budgetaufteilung vorschlägt und dann aus diesen Vorschlägen eine Budgetaufteilung (Allokation) bestimmt...

Symmetric and asymmetric committees

Ben-Yashar, Ruth; Danziger, Leif - 2011

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 various skill levels and each committee has an odd number of members. Surprisingly, even with the symmetric assumptions in...

Computational complexity in additive hedonic games

Dimitrov, Dinko; Sung, Shao-chin - 2008

We investigate the computational complexity of several decision problems in hedonic coalition formation games and demonstrate that attaining stability in such games remains NP-hard even when they are additive. Precisely, we prove that when either core stability or strict core stability is under...

Truth-Seeking Judgment Aggregation over Interconnected Issues

Bozbay, Irem - 2012

introducing the private information underlying individuals' judgments. Individuals share a common preference for reaching true … collective judgments, but hold private information about what the truth might be. Information conflicts may occur both between … lead to collective judgments that efficiently incorporate all private information. We characterize the (rare) situations in …

Voting for compromises: Alternative voting methods in polarized societies

Alós-Ferrer, Carlos; Buckenmaier, Johannes - 2021

Democratic societies have been increasingly confronted with extreme, knife-edge election outcomes that affect everybody's lives and contribute to social instability. Even if political compromises based on social conventions as equity or economic arguments as efficiency are available, polarized...

Cost Sharing in Collective Contests

Nitzan, Shmuel; Ueda, Kaoru - 2014

This paper studies collective contests with endogenous cost sharing, general effort costs and intra-group heterogeneity of prize-valuation. Our objective is to clarify the relationship between cost sharing, intra-group heterogeneity within the competing groups and the elasticity of the marginal...

When is Voting Optimal?

Ben-Yashar, Ruth; Danziger, Leif - 2014

We consider a framework where the optimal decision rule determining the collective choice depends in a simple way on the decision makers' posterior probabilities of a particular state of nature. Nevertheless, voting is generally an inefficient way to make collective choices and this paper sheds...
