| Abstract: | Arrow’s theorem is based on two “vertical” aggregation conditions expressed in terms of the relative positions of two alternatives in a preference ranking. This note obtains the same result for the strict preference case using instead two “horizontal” aggregation conditions expressed in terms of the absolute position of an alternative in a preference ranking. |
