  1. Shmuel Nitzan, A Further Characterization of Borda Ranking Method.
    below) is the so called Borda ranking method. Our work differs from the previous studies in three respects: First, in our model each individual's list of paired comparisons of the alternatives is assumed to be connected and asynunetric and not necessarily transitive.

  2. Ruth Ben-Yashar & Shmuel Nitzan (forthcoming). On the Significance of the Prior of a Correct Decision in Committees. Theory and Decision:1-11.
    The current note clarifies why, in committees, the prior probability of a correct collective choice might be of particular significance and possibly should sometimes even be the sole appropriate basis for making the collective decision. In particular, we present sufficient conditions for the superiority of a rule based solely on the prior relative to the simple majority rule, even when the decisional skills of the committee members are assumed to be homogeneous.

    In certain judgmental situations where a “correct” decision is presumed to exist, optimal decision making requires evaluation of the decision-makers’ capabilities and the selection of the appropriate aggregation rule. The major and so far unresolved difficulty is the former necessity. This article presents the optimal aggregation rule that simultaneously satisfies these two interdependent necessary requirements. In our setting, some record of the voters’ past decisions is available, but the correct decisions are not known. We observe that any arbitrary evaluation of (...)

    Committee decision making is examined in this study focusing on the role assigned to the committee members. In particular, we are concerned about the comparison between committee performance under specialization and non-specialization of the decision makers. Specialization (in the context of project or public policy selection) means that the decision of each committee member is based on a narrow area, which typically results in the acquirement and use of relatively high expertise in that area. When the committee members’ expertise is (...)

    Many voting rules and, in particular, the plurality rule and Condorcet-consistent voting rules satisfy the simple-majority decisiveness property. The problem implied by such decisiveness, namely, the universal disregard of the preferences of the minority, can be ameliorated by applying unbiased scoring rules such as the classical Borda rule, but such amelioration has a price; it implies erosion in the implementation of the widely accepted majority principle . Furthermore, the problems of majority decisiveness and of the erosion in the majority principle (...)

  6. Kobi Kriesler & Shmuel Nitzan (2008). Is Context-Based Choice Due to Context-Dependent Preferences? Theory and Decision 64 (1):65-80.
    The rationalization of context-based choice is usually based on the assumption that preferences are context-dependent. In this paper, we show that context-based choice can be due to the characteristics of the choice procedure applied by the individual and not to the dependence of preferences (stochastic or deterministic) on the context. Our arguments are illustrated focusing on the much-studied dominated-alternative effects.

    This paper clarifies why editors of academic journals should share with their referees the information about the number of referees they consult and the decision rule they apply. Our analysis also rationalizes the common questionable phenomenon of editors who seem to distort the yes or no recommendations of their referees. The editors request a recommendation of whether to accept or reject the paper as well as an assessment of the paper. The editors need the complete reports to make the appropriate (...)
