Template-Type: ReDIF-Paper 1.0 Title: A Theory of Auditability for Allocation Mechanisms Author-Name: Aram Grigoryan Author-Email:ag@ucsd.edu Author-Name: Markus Möller Author-Email: mmoelle2@uni-bonn.de Classification-JEL: C78, D47, D82 Keywords: Matching and Allocation, Auditability, Deviation Detection, In centralized mechanisms and platforms, participants do not fully observe each others' type reports. Hence, if there is a deviation from the promised mechanism, participants may be unable to detect it. We formalize a notion of auditabilty that captures how easy or hard it is to detect deviations from a mechanism. We find a stark contrast between the auditabilities of prominent mechanisms. We also provide tight characterizations of maximally auditable classes of allocation mechanisms.
