When a user shares multi-dimensional data about themselves with a firm, the firm learns about the correlations of different dimensions of user data. We incorporate this type of learning into a model of a data market in which a firm acquires data from users with privacy concerns. User data is...

We study how a monopolist's use of consumer data for price discrimination affects welfare. To answer this question, we develop a model of market segmentation subject to residual uncertainty. We fully characterize when data usage monotonically increases or decreases welfare or when the effect is...

Customer privacy is increasingly important to marketers. High-profile breaches of databases containing sensitive customer information, and the growing need to build the infrastructure required to support analysis of big data, present nontrivial obstacles to researchers seeking individual-level...

Customer data offers monetization opportunities but also entails potential risks for many businesses because of customer privacy concerns. Despite the increasing importance of these trade offs, there is limited research of their impact on businesses. To address this gap, we develop a theoretical...

In a market where consumers choose between payment options and firms compete with products and prices, we show that payment data drives the formation of a market monopoly. A data-sharing policy can successfully restore and maintain a competitive market, but often at the expense of both...

In almost all sectors, online services play a much larger role than a few years ago. Data-driven platform models combine an ever greater degree of market power. The associated concentration effect leads to the displacement of medium-sized companies from the market. When looking at the large...

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.

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...

Kundendaten und deren Verarbeitung stellen für Unternehmen nahezu aller Branchen und Größenklassen einen zunehmend wettbewerbskritischen, jedoch gleichzeitig herausfordernden Faktor dar. Unter dem Konzept eines Daten-Netzwerkbetriebs adressiert Der Mittelstandsverbund – ZGV e.V. die...
