A smooth model of decision making under ambiguity

  • Peter Klibanoff


  • Massimo Marinacci


  • Sujoy Mukerji


We propose and axiomatize a new model of preferences that achieves a separation between ambiguity, identified as a characteristic of the decision maker's subjective information, and ambiguity attitude, a characteristic of the decision maker's tastes.
