A Class of Incomplete and Ambiguity Averse Preferences

Listed author(s):
  • Leandro Nascimento
  • Gil Riella

This paper characterizes ambiguity averse preferences in the absence of the completeness axiom. We axiomatize multiple selves versions of some of the most important examples of complete and ambiguity averse preferences, and characterize when those incomplete preferences are ambiguity averse.
