      Freixas Bosch, Josep (CRC Press, 2019-12-06)
      Part of book or chapter of book
      Restricted access - publisher's policy
      A value that has all the ingredients to be a generalization of the Shapley value is proposed for a large class of games called j-cooperative games which are closely related to multi-choice games. When it is restricted to ...

      Amer Ramon, Rafael; Giménez Pradales, José Miguel; Magaña Nieto, Antonio (2012-02)
      Article
      Restricted access - publisher's policy
      The aim of this paper consists of constructing accessibility measures to the nodes of directed graphs using methods of Game Theory. Since digraphs without a predefined game are considered, the main part of the paper is ...

      Bernardi, Giulia; Freixas Bosch, Josep (2019-01-01)
      Article
      Open Access
      The aim of this work is to give a characterization of the Shapley–Shubik and the Banzhaf power indices for (3,2)-simple games. We generalize to the set of (3,2)-simple games the classical axioms for power indices on simple ...
    • An equivalent formulation for the Shapley value 

      Freixas Bosch, Josep (Springer, 2018-12-30)
      Part of book or chapter of book
      Open Access
      An equivalent explicit formula for the Shapley value is provided, its equivalence with the classical one is proven by double induction. The importance of this new formula, in contrast to the classical one, is its capability ...

    • Anonymous yes-no voting with abstention and multiple levels of approval 

      Freixas Bosch, Josep; Zwicker, William S. (Academic Press, 2009-11)
      Article
      Open Access
      Els jocs simples simètrics (3, 2) serveixen de models per a sistemes de votació anònims en els quals cada votant pot votar "sí", abstenir-se, o votar "no", el resultat és "sí" o "no", i els votants juguen papers intercanviables. ...

    • Bounds for the Nakamura number 

      Freixas Bosch, Josep; Kurz, Sascha (Springer, 2019-04)
      Article
      Open Access
      The Nakamura number is an appropriate invariant of a simple game to study the existence of social equilibria and the possibility of cycles. For symmetric (quota) games its number can be obtained by an easy formula. For ...
    • Celebrity games
