A Note on 'Resolving Conflicting Preferences in School Choice : The 'Boston Mechanism' Reconsidered'

This note corrects a result of Abdulkadiroglu et al. (2011). Assuming incomplete information, common ordinal preferences, and no school priorities in the school choice model, Abdulkadiroglu et al. (2011) prove that naive students benefit from the presence of sophisticated students. They state in their paper and formally prove in their online appendix that, if they turn to assuming complete information and strict priorities as in the standard school choice model, naive students will never benefit from the presence of sophisticated students. We show that this result is actually wrong
