A Behavioral Arrow Theorem
In light of research indicating that individual behavior may violate standard rationality assumptions, we introduce a model of preference aggregation in which neither individual nor collective preferences must satisfy transitivity or other coherence conditions. We introduce an ordinal rationality measure to compare preference relations in terms of their level of coherence. Using this measure, w...
متن کاملA Quantitative Arrow Theorem
Arrow’s Impossibility Theorem states that any constitution which satisfies Independence of Irrelevant Alternatives (IIA) and Unanimity and is not a Dictator has to be non-transitive. In this paper we study quantitative versions of Arrow theorem. Consider n voters who vote independently at random, each following the uniform distribution over the 6 rankings of 3 alternatives. Arrow’s theorem impl...
متن کاملA Note on the Arrow-Lind Theorem
Kenneth Arrow and Robert Lind have recently proved a theorem on risky public projects, stating that under certain conditions the social cost of the risk tends to zero as the population tends to infinity, so that projects can be evaluated on the basis of expected net benefit alone. The present note gives an alternative formulation and a short new proof of the theorem, and uses these to examine t...
متن کاملArrow ' s Theorem with a Fixed Feasible Alternative *
Arrow's Theorem, in its social choice function formulation, assumes that all nonempty finite subsets of the universal set of alternatives is potentially a feasible set. We demonstrate that the axioms in Arrow's Theorem, with weak Pareto strengthened to strong Pareto, are consistent if it is assumed that there is a prespecified alternative which is in every feasible set. We further show that if ...
متن کاملArrow ’ s theorem and the Gibbard - Satterthwaite theorem : a unified approach *
The connection between Arrow’s theorem and the Gibbard-Satterthwaite theorem is further strengthened by providing a single proof that yields both results. 2001 Elsevier Science B.V. All rights reserved.
