Abstract: Reputation is a crucial concept in dynamic multiagent environments and not surprisingly has received considerable attention from researchers.However, despite the large body of related work on reputation systems, no metrics exist to directly and quantitatively evaluate and compare them.We present a common conceptual interface for reputation systems and a set of four measurable desiderata that are broadly applicable across multiple domains.These desiderata employ concepts from dynamic systems theory to measure how a reputation system reacts to a strategic agent attempting to maximize its own utility.We study a diverse set of well-known reputation models from the literature in a moral hazard setting and identify a rich variety of characteristics that they support.We discuss the implications, strengths, and limitations of our desiderata.
