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...

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...

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...

For a market with a finite number of agents, pairwise matching, and bargaining, it is shown that, even when the market is frictionless, the equilibrium is not necessarily competitive. It depends on the amount of information agents use. If their behavior is conditioned only on the sets of agents...
