Impossibility theorems and voting paradoxes in collective choice theory
In the field of positive political theory, the term “impossibility theorem” refers to a collection of results that take as given a set of normatively appealing criteria and deductively prove that such a set of criteria are inconsistent: that is it impossible for a voting system – any voting system – to simultaneously satisfy the given set of criteria. This approach to studying voting systems is...
متن کاملImpossibility and Feasibility Results for Zero Knowledge with Public Keys
In this paper, we continue the study the round complexity of black-box zero knowledge in the bare public-key (BPK, for short) model previously started by Micali and Reyzin in [11]. Specifically we show the impossibility of 3-round concurrent (and thus resettable) black-box zeroknowledge argument systems with sequential soundness for non-trivial languages. In light of the previous state-of-the-a...
متن کاملImpossibility Results for the Equational Theory of Timed CCS
We study the equational theory of Timed CCS as proposed by Wang Yi in CONCUR’90. Common to Wang Yi’s paper, we particularly focus on a class of linearly-ordered time domains exemplified by the positive real or rational numbers. We show that, even when the set of basic actions is a singleton, there are parallel Timed CCS processes that do not have any sequential equivalent and thus improve on th...
متن کاملAggregating Sets of Judgments: Two Impossibility Results Compared1
The “doctrinal paradox” or “discursive dilemma” shows that propositionwise majority voting over the judgments held by multiple individuals on some interconnected propositions can lead to inconsistent collective judgments on these propositions. List and Pettit (2002) have proved that this paradox illustrates a more general impossibility theorem showing that there exists no aggregation procedure ...
متن کاملArrow’s Impossibility Theorem on Social Choice Systems
Social choice theory is a field that concerns methods of aggregating individual interests to determine net social preferences. Arrow’s Impossibility Theorem states that no social choice system can satisfy all requirements in a collection of “reasonable” criteria. We make the notion of “reasonable” voting systems precise by stating the four properties that voting systems must have in order to be...
