Abstract

Ever since Sen (1993) criticized the notion of internal consistency of choice, there exists a widespread perception that the standard rationalizability approach to the theory of choice has difficulties in coping with the existence of external norms. We introduce a concept of norm-conditional rationalizability and show that external norms can be made compatible with the methods underlying the rationalizability approach. This claim is substantiated by characterizing norm-conditional rationalizability by means of suitably modified revealed preference axioms in the theory of rational choice on general domains due to Richter (1966; 1971) and Hansson (1968).
