This paper considers lexical combinations of choice functions where at least one is interpreted as arising from a norm. It is shown that in for all possibilities in which a norm is present, in general final choice may be consistent with preference optimization, but that it need not be so. It is concluded therefore that a fruitful approach to understanding the effect of norms on choice is to consider particular classes of norms rather than norms in general as in the (...) work by Wulf Gaertner among others.

A generalized theory of revealed preference is formulated for choice situations where the consequences of choices from given menus are uncertain. In a nonprobabilistic framework, rational choice behavior can be defined by requiring the existence of a preference relation on the set of possible consequences and an extension rule for this relation to the power set of the set of consequences such that the chosen sets of possible outcomes are the best elements in the feasible set according to this extension (...) rule. Rational choice is characterized under various assumptions on these relations. (shrink)

This paper develops a general and unified framework to discuss individual choice behaviors that are constrained by the individual’s internalized norms. We propose a new notion of rationalizablity of a choice function that incorporates such constraints, and axiomatically study several norm-constrained choice behaviors.
