In chapter 4 we saw that the weighted sum is a simple method of aggregating preferences. However, this type of aggregation does pre-suppose a certain number of assumptions on the nature of the decision maker’s preferences; these assumptions are quite strong and by no means simple to explain, as we shall see in this chapter. The key question is: what properties must the decision maker’s preferences satisfy if they are to be expressed in the form of a sum of utility functions?
