As was first pointed out to us by John Hegeman,1 the proof of Claim 3, Theorem 1, in Dutta et al. (2007) is not correct, since it is based on interchanging two limits which is not justified without, for instance, a continuity assumption. In this note we first give an alternative proof of kj A.'.. By Claim 2 we can take u' with z(u') = aj and for simplicity u'(a) = 0 for all a ^ uj. Let 0 < s < j(kj ■ kfj) and let t?2 be so small that '<Pj(u', iijy) k'.' < e. Observe that agent l's utility in this profile is equal to <Pj(u', w?j).
