文摘

We characterize choice correspondences that can be rationalized by a procedure that is a refinement of the prudent choices exposed in (Houy, 2010). Our characterization is made by means of the usual expansion axiom γ and a weakening of the usual contraction axiom α. We also make a link with traditional rationality.
