Now comes a very important contagion result which contains the hardest part of the proof. 1. If there is some individual J who is almost decisive for some ordered pair of alternatives (x, y), an Arrovian social welfare function f satisfying conditions U , P and I implies that J must have dictatorial power. Proof. e. for some x, y ∈ X , D(x, y). Let there be a third alternative z and let index i refer to all the other members of the society. According to condition U , we are absolutely free to choose any of the logically possible preference profiles for this society.

For all (R1 , . . , Rn ) and for any x, y ∈ X : xPy ↔ [N (xPi y) > 12 · |N | ], yPx ↔ [N (yPi x) > 12 · |N | ], and xIy otherwise. In the following example, it is argued that positive responsiveness is satisfied by the simple majority rule but not by the absolute majority rule. Consider a small society of seven voters where two individuals prefer x to y, two individuals prefer y to x and the rest is indifferent between x and y. e. xIy. Now assume that one of the hitherto indifferent voters declares a strict preference for x over y, with everyone else’s preference between x and y remaining the same.

1. The simple majority rule We have seen in Chapter 2 that any social welfare function satisfying unrestricted domain and the weak Pareto condition as well as Arrow’s independence condition and the requirement that the generated social relation be an ordering is doomed to be dictatorial. As already mentioned in Chapter 2, Arrow considered these conditions as necessary requirements in the sense that they express both rationality and the doctrines of citizens’ sovereignty in a very general way. Is this then the end of the story?
