Do Incentives to Review Help the Market? Evidence from a Field Experiment on Airbnb
Marketing Science (MKTGS), Volume 42, Issue 5September-October 2023, Pages 853–865https://doi.org/10.1287/mksc.2023.1439We study a field experiment of an incentivized review program on Airbnb and quantify its impact on reviewing behavior and market outcomes.
Many online reputation systems operate by asking volunteers to write reviews for free. As a result, a large share of buyers do not review, and those who do review are self-selected. This can cause the reputation system to miss important information about ...
