Most of game theory, welfare economics, and choice theory is consequentialist in nature. What really matters in these analyses are outcomes, which are often measured in terms of utilities or monetary payoffs. Non-consequentialist features may, however, matter. The procedural aspect behind availability of alternatives may induce an individual to abstain from choosing any element at all so that the choice set becomes empty. This chapter relates the concept of choice to procedural aspects of different kinds. Availability of objects, different aspects of production as such, and shrinkages from an originally given set of options to several of its subsets are considered. Rationalizability of choice in such contexts is studied axiomatically. The chapter relates conditions to the standard consistency conditions from traditional choice theory. It finally makes a suggestion how to derive an ordering over different procedures.

Keywords:   non-consequentialist approach, procedural aspects, choice functions, rationalizability, consistency
