Market Design Choices, Racial Discrimination, and Equitable Microentrepreneurship in Digital Marketplaces
研究了数字市场中质量认证能否减少种族歧视，发现Airbnb的超级房东认证使黑人房东受益程度是其他房东的1.5倍，且不损害非超级房东黑人房东的利益。
This study investigates the potential of market design choices, specifically quality certification, to mitigate racial discrimination in digital marketplaces. Using a regression discontinuity design (RDD) that exploits the discontinuity in Airbnb’s Superhost assignment, we find that Black hosts benefit 1.5 times more from the quality certification than other hosts. Moreover, we find compelling evidence that this disproportionate increase does not come at the expense of non-Superhost Black hosts. This suggests that quality certification can effectively reduce discrimination and promote equitable outcomes. Further, our analysis utilizing a doubly robust machine learning approach reveals that the effectiveness of quality certification persists even in the prominent presence of consumer reviews, a widely used market feature and a credible user-generated quality signal. Our research underscores the judicious use of market design in fostering equity for minority entrepreneurs in digital marketplaces. This paper was accepted by Hemant Bhargava, information systems.
