Supplemental Appendix to “Identifying the Harm of Manipulable School-Choice Mechanisms”

In Dur, Hammond, and Morrill (2017), we provided evidence in favor of a novel classification methodology for identifying sincere and sophisticated students in school-choice matching mechanisms. Our approach allowed us to demonstrate support for previously untested claims in the theoretical matching literature regarding the distributional consequences of using a manipulable mechanism. In this appendix, we present additional evidence and robustness checks that complement those in the paper. First, we document the robustness of our analysis. Second, we present additional evidence supporting the classification of students into categories of sincere and sophisticated.
