  1. Comparison of the Polar Decision Rules for Various Types of Distributions.Luba Sapir - 2004 - Theory and Decision 56 (3):325-343.
    We focus on the dichotomous choice model, which goes back as far as Condorcet (1785; Essai sur l'application de l'analyse a la probabilité des décisions rendues a la pluralité des voix, Paris). A group of experts is required to select one of two alternatives, of which exactly one is regarded as correct. The alternatives may be related to a wide variety of areas. A decision rule translates the individual opinions of the members into a group decision. A decision rule is (...)

  • Optimal Committee Composition: Diversity, Bias, and Size.Peter Stone & Koji Kagotani - unknown
    The Condorcet Jury Theorem, together with a large and growing literature of ancillary results, suggests two conclusions. First, large committees outperform small committees, other things equal. Second, heterogeneous committees can, under the right circumstances, outperform homogeneous ones, again other things equal. But this literature has done little to bring these two conclusions together. This paper compares the respective contributions of size and difference to optimal committee performance, and draws policy recommendations using these comparisons.

  • General Representation of Epistemically Optimal Procedures.Franz Dietrich - 2006 - Social Choice and Welfare 2 (26):263-283.
    Assuming that votes are independent, the epistemically optimal procedure in a binary collective choice problem is known to be a weighted supermajority rule with weights given by personal log-likelihood-ratios. It is shown here that an analogous result holds in a much more general model. Firstly, the result follows from a more basic principle than expected-utility maximisation, namely from an axiom (Epistemic Monotonicity) which requires neither utilities nor prior probabilities of the ‘correctness’ of alternatives. Secondly, a person’s input need not be (...)

  • Committee Decisions with Partisans and Side-Transfers.Mehmet Bac & Parimal Kanti Bag - 2002 - Theory and Decision 52 (3):267-286.
    A dichotomous decision-making context in committees is considered where potential partisan members with predetermined votes can generate inefficient decisions and buy neutral votes. The optimal voting rule minimizing the expected costs of inefficient decisions for the case of a three-member committee is analyzed. It is shown that the optimal voting rule can be non-monotonic with respect to side-transfers: in the symmetric case, majority voting is optimal under either zero, mild or full side-transfer possibilities, whereas unanimity voting may be optimal under (...)
