On fairness of equilibria in economies with differential information

  • Achille Basile


  • Maria Graziano


  • Marialaura Pesce


The paper proposes a notion of fairness which overcomes the conflict arising between efficiency and the absence of envy in economies with uncertainty and asymmetrically informed agents. We do it in general economies which include, as particular cases, the main models of differential information economies, providing in this framework a natural competitive equilibrium notion which satisfies the fair criterion. The analysis is conducted allowing the presence of large traders, which may cause the lack of perfect competition. Copyright Springer Science+Business Media New York 2014
