In the recent development of the sharing economy and other peer-to-peer digital markets, (ethnic) discrimination has become an important issue. Reputation systems are often put forward as the most promising solution to (ethnic) discrimination in the platform economy. This claim is based on the finding that the ethnic gap is smaller for users with reviews than for users without reviews. However, as reviews are only written after completed interactions, the chance to get a review may not be equal for all users. Hence, initial differences between users in the probability to be selected for a transaction may accumulate over time, thereby diminishing the potential of reputation systems to decrease discrimination. Previous studies have overlooked this potentially negative effect of reputation systems. In the current study we use data use data from a peer-to-peer motorcycle sharing platforms to study the relation between reputation systems and discrimination. In the current paper we do not find evidence for the potential of reputation systems to reduce the ethnic gap. Rather, we find that the ethnic gap persists even for renters with a positive rating. Regardless of the reputation of the renter, requests from renters with more non-Dutch sounding names are less likely to be accepted. This decreases their probability to get a (positive) review, which in turn negatively affects their chances to participate in future interactions.
