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...

This paper investigates fair (i.e., envy free and efficient) allocations in an overlapping generations economy without production and with two - period lived agents. We show that there exists a conflict between no-envy and efficiency when all generations have identical preferences. This conflict...

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...

We consider collective decision problems where some agents have private information about alternatives and others don't. Voting takes place under strategy-proof rules. Prior to voting, informed agents may or may not disclose their private information, thus eventually influencing the preferences...

In response to recent work on the aggregation of individual judgments on logically connected propositions into collective judgments, it is often asked whether judgment aggregation is a special case of Arrowian preference aggregation. We argue the op- posite. After proving a general impossibility...

I explore a novel approach to preference and proposal aggregation theory. My approach relies on abstract algebra and elementary group theory. The use of abstract algebra and the notion of homomorphism not only enable the formalization of such concepts as "divergent preferences", "status quo...
