Who Forgoes Screening in Online Markets and Why? Evidence from Airbnb
研究了Airbnb房东为何自愿放弃对房客的筛选（使用即时预订功能），发现放弃筛选虽导致评分下降，但能提高入住率，且对黑人和女性房东效果更强，讨论了歧视与社会福利含义。
Screening is considered a necessary mechanism for alleviating information asymmetry but has also raised concerns about increased discrimination in online peer-to-peer market platforms. Paradoxically, providers of goods and services may also voluntarily forgo screening, even though it increases the risks and costs associated with poor matches. We examine who may choose to forgo screening and why, and its impact on their performance outcomes. Our study’s empirical context is the Airbnb platform, wherein the “Instant Book” feature enables hosts to forgo the screening of guests. Utilizing a unique panel dataset of all listings in New York City during August 2015-February 2017, we first explore the antecedents of voluntarily switching to instant booking and then causally identify the impacts of switching. Our study provides evidence of the economic benefits of forgoing screening from increased occupancy even as review ratings decline; these effects are stronger for Black and female hosts. We discuss the strategic and social welfare implications of these findings within the context of current conversations on discrimination and bias in the sharing economy.
