Erratum

Abstract

A line of text was missing from the paragraph that begins at the bottom of page 628 and continues on page 630. The paragraph read as follows: How effective is the alternative vote in this respect? With (a) exclusively single-peaked preferences and (b) a four-party contest and (c) with no party securing a first-count majority of first preferences, the party corresponding to the preferences of the median is majority first-preference support in both communities for moderate parties, Fraenkel and Grofman (2004) show that the median party cannot be eliminated. The correct version should have read: How effective is the alternative vote in this respect? With (a) exclusively single-peaked preferences and (b) a four-party contest and (c) with no party securing a first-count majority of first preferences, the party corresponding to the preferences of the median voter must be one of the moderate parties. If, under such circumstances, there is majority first-preference support in both communities for moderate parties, Fraenkel and Grofman (2004) show that the median party cannot be eliminated
