An Example: Social Choice

In this chapter we shall apply some of the concepts presented in earlier chapters to a well-known subject, social choice theory. Social choice theory is rather closely related to group decision theory, although the exact character of the relation is hard to state. What is said here seems equally applicable to both subjects. We use the terminology from social choice theory essentially in accordance with Arrow (1951, 1963), Sen (1970) and Luce & Raiffa (1957). Our purpose is primarily to exemplify what has been said in earlier sections and not to conduct an analysis of the problem of social choice.
