This paper proposes an intuitive definition of status quo that is model-free and given in terms of observable choices only. We do not rationalize status quo-dependent preferences, to the contrary, we show that models of decision under ambiguity already predict behavioral phenomena ascribed to...

This paper considers local and global multiple-prior representations of ambiguity for preferences that are (i) monotonic, (ii) Bernoullian, i.e. admit an affine utility representation when restricted to constant acts, and (iii) locally Lipschitz continuous. We do not require either Certainty...
