An individual displays various preference orderings in different payoff-irrelevant circumstances. It is assumed that the variation in the observed preference orderings is the outcome of some cognitive process that distorts the underlying preferences of the individual. We introduce a framework...

We develop a framework for modelling choice in the presence of framing effects. An extended choice function assigns a chosen element to every pair (A, f) where A is a set of alternatives, and f is a frame. A frame includes observable information that is irrelevant in the rational assessment of...

The standard economic choice model assumes that the decision maker chooses from <i>sets</i> of alternatives. In contrast, we analyze a choice model in which the decision maker encounters the alternatives in the form of a <i>list</i>. We present two axioms similar in nature to the classical axioms of choice...
