The Design of Feedback Revision Rules - An Experimental Study
AbstractOnline platforms often employ feedback systems and allow to revise submitted feedback under certain conditions. We experimentally study potential strategic problems in the feedback revision process and possible improvements. We document the negative effects on informativeness and market-enhancingness of feedback when feedback revision rules allow for strategic behavior. We propose small improvements to the feedback revision process that aim to address these problems. Our laboratory experiment indicates that the improved system mitigates and partly reverses the negative effects of wrongly designed revision options.
Team Competition and Driver Productivity in Ride-sharing: A Natural Field Experiment at Didi
AbstractWhile the sharing economy benefits workers with autonomy and flexibility, the lack of a strong identity from work and bonds with colleagues can lead to low engagement with the platform. To address this issue, we run a field experiment to create teams for drivers at Didi. We vary the recommender algorithm and find that drivers are most likely to join a team when the recommendation is based on hometown similarity. Once teams are formed, they enter into a week-long contest. We find that both randomly-formed teams and teams of age similarity have the highest productivity increase compared to the placebo.
