MWITA-LRO-2026-011 · Evidence A · P1
In Expedia's randomized-ranking sample, click and booking probabilities decline materially with lower position; a modeled consumer-surplus ranking would outperform Expedia's ranking by $1.205 consumer surplus and $0.084 platform revenue per impression.
What this does not establish
Ranking position is randomized in an OTA hotel choice set, not Google Maps or organic local search; optimized-ranking gains are structural-model simulations, not a deployed field-test lift or an effect of review count.
Counterevidence & uncertainty
Ranking strongly shapes discovery, but maximizing platform revenue alone lowers modeled consumer surplus by $0.3826; a simple utility ranking also loses $0.1520 revenue versus Expedia.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral or commercial outcomes.
