MWITA-RCO-2026-012 · Evidence A · P1
Incentivizing first reviews increased listing attention and transaction count but did not increase nights sold or booking value.
What this does not establish
Airbnb's 2014-2016 reputation system, first-review setting and supply-constrained markets do not generalize directly to current retail review programs; publication predates the preferred 2024-2026 window.
Counterevidence & uncertainty
Higher review volume and booking count did not produce greater quantity sold or revenue, providing a direct counterexample to review-count optimization.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
