Rational choice and von Neumann-Morgenstern's stable set: the case of path-dependent procedures

Describing a procedure in which choice proceeds in a sequence, we propose two alternative ways of resolving the decision problem whenever the outcome is sequence sensitive. One way yields a rationalizable choice set, and the other way produces a weakly rationalizable choice set that is equivalent to...

Description
Summary:Describing a procedure in which choice proceeds in a sequence, we propose two alternative ways of resolving the decision problem whenever the outcome is sequence sensitive. One way yields a rationalizable choice set, and the other way produces a weakly rationalizable choice set that is equivalent to von Neumann-Morgenstern's stable set. It is shown that for quasi-transitive rationalization, the maximal set must coincide with its stable set.
