Abstract:

Reputation badges are widely used in digital marketplaces. To investigate their impact on pricing, we develop a consumer search model with stochastic prominence. Under supermartingale exposure algorithms, which front-load badged sellers in search rankings, we show that badged sellers strategically lower their prices to discourage consumers from continued search. Non-badged sellers, by contrast, face less elastic demand and therefore optimally set higher prices. Empirically confirming the algorithm’s supermartingale property, we test this discount effect for Airbnb’s “Superhost” badge using a regression discontinuity design that exploits the strict host-rating threshold of 4.8. We find that obtaining the Superhost badge reduces listing prices by 16.5 percent, while losing the badge raises them by 15.5 percent.
