  • Fairness preferences over allocation of scarce medical resources

    Open AccessZijing Yang, Tigran Melkonyan et al.ARTICLESocial Science & Medicine2025Referências: 36

    Many argue that randomization is a fair way to allocate scarce resources. However, little is known about individual justice preferences for these mechanisms. This gap is particularly consequential, as public choices are often influenced by individual justice preferences. To address it, we propose a model using proportional probability weights for recipients' claims and conduct an empirical analysis using a longitudinal survey on allocating medica…

  • Calibration Results for Incomplete Preferences

    Zvi Safra, Uzi SegalARTICLERevue économique2020

    Dans cet article, nous démontrons que, dans le modèle d’utilité espérée, les préférences incomplètes sont sujettes à une critique similaire à celle adressée à leurs analogues complètes : même un degré modeste d’aversion à de petits risques suffit à impliquer un degré extrême et déraisonnable d’aversion à de grands risques. Nos résultats mettent ainsi en doute la pertinence théorique et pratique des préférences incomplètes dans le modèle d’utilité…

  • Generalized Utilitarianism and Harsanyi's Impartial Observer Theorem

    Open AccessSimon Grant, Atsushi Kajii et al.ARTICLEEconometrica2010

    Harsanyi's impartial observer must consider two types of lotteries: imaginary identity lotteries (“accidents of birth”) that she faces as herself and the real outcome lotteries (“life chances”) to be faced by the individuals she imagines becoming. If we maintain a distinction between identity and outcome lotteries, then Harsanyi-like axioms yield generalized utilitarianism, and allow us to accommodate concerns about different individuals' risk at…

  • Connectedness of the set of manipulable equilibria

    Open AccessZvi SafraARTICLEMathematical Social Sciences1990Referências: 11

    An equilibrium is manipulable if there exists a coalition that, by reallocating its members' endowments, can force a movement from that equilibrium to another one that is strictly preferred by every member of it. It is shown in this work that, in the framework of pure exchange economies, the set of manipulable equilibria is arc-connected (a property that is not shared by its complement)
