In order to incorporate recent developments in Bounded Rationality and Behavioral Economics into Choice Theory, we introduce the notion of an extended choice problem (A,f) where A is a set of alternatives and f is a frame. A frame consists of observable information that appears to be irrelevant...

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...

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...
