Core and Equilibria under ambiguity

  • Luciano De Castro
  • Marialaura Pesce
  • Nicolas Yannelis

This paper introduces new core and Walrasian equilibrium notions for an asymmetric information economy with non-expected utility preferences. We prove existence and incentive compatibility results for the new notions we introduce.
