This article analyses the crucial role of user data for digital markets contestability and presents policy proposals devised to address growing concerns about the dominance of data-rich incumbents in digital markets.

Firms have ever increasing access to consumer data, which they use to personalize their advertising and to price discriminate. This raises privacy concerns. Policymakers have argued in response that consumers should be given control over their data, able to choose what to share and when. Since...

The growth of the availability and use of detailed household financial transaction microdata has dramatically expanded the ability of researchers to understand both household decision-making as well as aggregate fluctuations across a wide range of fields. This class of transaction data is...

Die Verteilung von Daten und Informationen nimmt innerhalb der Verbundgruppen eine tragende Rolle ein und ist daher bereits seit Jahren ein wichtiger Gegenstand der empirischen Kooperationsforschung. Durch eine branchenübergreifend zu beobachtende, stetig wachsende Absatzmarktorientierung...

Companies near constantly surveil their customers to collect, analyze, and profit from their private information. A prevailing concern is that the market for private data and security breaches expose consumers to financial fraud. In this study, we exploit Apple's App Tracking Transparency (ATT)...

A data intermediary pays consumers for information about their preferences and sells the information so acquired to firms that use it to tailor their products and prices. The social dimension of the individual data - whereby an individual's data are predictive of the behavior of others -...

We model social media platforms that have proprietary information about their users and sell targeted ad space to producers. Producers, who can be incumbents or entrants, compete for the attention of final consumers. We characterize equilibrium producer entry and consumer welfare in terms of...
