Google skews search results in anticompetitive behavior says new study by Yelp and leading academic Tim Wu
Google's search practices come under scrutiny from leading academic Wu — Tim Wu, author of The Master Switch: The Rise and Fall of Information Empires, argues in a paper that Google …
Context & Ripple Effects
Tim Wu — whose book traced how information empires rise and fall through control of distribution — lends academic weight to a complaint Yelp has been pressing for years: that Google displays its own properties above vertical competitors in search results. This 2015 paper is the intellectual foundation of what became Yelp's six-year campaign to persuade antitrust regulators to sanction Google.
The arc matters because it did not end with the paper: Yelp's own tests of Google's EU Digital Markets Act design tweaks still found users steered away from clicking out, and in 2024 Yelp escalated to court, alleging Google abuses its dominance in general search for advantage in local search and local search advertising.
First-order effects
- Google's self-preferencing practice is now backed by named academic research rather than just a rival competitor's grievance, raising the evidentiary bar Yelp can cite before regulators.
- Regulators weighing whether to act against Google gain a ready-made scholarly framework for treating search-result placement as an abuse of dominance.
Second-order effects
- Other vertical content providers squeezed below Google's own listings gain a template for documenting harm, broadening the complaint base beyond Yelp.
- Sustained pressure forces Google to defend result design publicly, as seen when Yelp later tested and disputed the tweaks Google made to comply with the EU's DMA.
Third-order effects
- If the pattern holds, challenge-by-study matures into challenge-by-lawsuit: nearly a decade after Wu's paper, Yelp sued Google over the same general-search dominance, shifting enforcement from regulator discretion to courts.
- Search-result placement becomes a durable antitrust battleground, entrenching the view that a dominant general search engine's promotion of its own services is a structural competition issue rather than a product-design choice.
The trend: This paper is an early data point in the decade-long escalation of self-preferencing claims against dominant platforms, running from academic critique through regulatory campaigns to direct litigation.
