Description du projet
Interventions des pouvoirs publics pour une concurrence loyale sur les marchés des applications
Les marchés d’applications tels que l’App Store d’Apple ou Google Play ont fait l’objet d’un examen minutieux de la part des régulateurs parce qu’ils favorisent leurs propres applications au détriment des applications tierces, ce qui peut fausser la concurrence et nuire à l’innovation. Toutefois, il n’est pas certain que l’on puisse intervenir de manière optimale contre ce type d’autoréférence. Le projet APPMARKETS, financé par le CER, vise à évaluer l’efficacité des interventions des pouvoirs publics contre l’autoréférence. Le projet évaluera les effets et les mécanismes de plusieurs interventions mises en œuvre dans le monde entier et les comparera pour valider les théories existantes. Les résultats aideront les parties prenantes et les agences gouvernementales à élaborer des stratégies appropriées. Le projet mènera quatre études quasi-expérimentales approfondies utilisant des données au niveau des produits sur les marchés des applications mobiles et intégrera les résultats dans une compréhension holistique en utilisant des protocoles de mesure et d’analyse.
Objectif
App markets—such as Apple’s App Store or Google Play—have significant economic importance and drive digital innovation. In 2021, the App Store alone facilitated transactions worth over EUR 511 Bn, which equals the GDP of Sweden.
However, app market operators have also attracted severe scrutiny from regulators due to their integrated gatekeeper structure: they operate a marketplace while also competing within them with their own apps. This gives app market operators an incentive for self-preferencing: they promote their own apps over third-party apps, consequently distorting competition and harming app innovation.
Uncertainty remains regarding how self-preferencing can effectively be counteracted with public policy interventions. Although legislators have advanced bills to restrict self-preferencing, including the Digital Markets Act, existing theoretical models are scant, make mixed predictions, and lack empirical validation. This uncertainty is problematic because app markets represent a complex node of the digital economy where regulatory interference—if not done “right”—can likewise harm innovation.
This project will empirically evaluate which public-policy interventions against self-preferencing are effective in restoring app developers’ innovation incentives. It will (i) explain the effects, conditions, and mechanisms through which the interventions function and compare, (ii) permit a validation of existing theory, and (iii) aid stakeholders and government agencies in developing appropriate strategies.
To achieve this objective, this project will (i) conduct four in-depth quasi-experimental studies, (ii) which exploit plausibly exogenous policy-changes against self-preferencing, (iii) leverage unique time-series product-level data from mobile app markets, and (iv) integrate the findings into a holistic understanding using measurement and analyses protocols. An extensive communication plan ensures the transfer of scientific expertise into public knowledge.
