Heterogeneous search costs enable price discrimination, which I study in the canonical Wolinsky (1986) sequential search setting. Firms observe a public signal of a consumer's search cost before posting a personalized price. The welfare effects of search-cost-based price discrimination depend on...

The European debate over personal data trading has become trapped between two unworkable extremes: the status quo of allowing platforms unfettered access to user data, or making data sharing so difficult it is effectively banned. Neither position serves consumers' interests. Personal data...

Platformisation and the growing adoption of AI-driven systems have intensified pervasive data extraction and appropriation that bring distinct harms for both individuals and societies at large. Yet, little is known about how distinct harm perceptions shape citizens' preferences for different...

Available open access digitally under CC-BY-NC-ND licence. Mobile apps have transformed how we live, work and connect – but at what cost? This book examines the immense power Apple and Google wield over society, arising from their control of app stores as well as mobile operating systems and...

"This pioneering book examines the legal, economic, and technological foundations of the proposed digital euro, and explores the potential design of an EU Central Bank Digital Currency (CBDC). Annelieke A.M. Mooij provides insights into the suggested legal framework behind the digital euro, as...

Machine learning credit scoring expands the informational frontier of retail lending, particularly for thin file borrowers, yet it also erodes the practical meaning of disclosure duties that anchor consumer protection and prudential oversight. The central financial implication is that...

Die Problemstellung, die diesem neuen Arbeitspapier zugrunde liegt, ist die Kritik an der bisherigen Etablierung des Datenschutzes in der ESG-Dimension und die Berücksichtigung dessen in dem ESG-Score, welcher eine grundlegende Orientierung für Investitionsentscheidungen von ESG-Anlegern...

We examine the trade-off between functionality and data privacy inherent in many AI products by conducting a randomized survey experiment with 1,734 participants from the US and several European countries. Participants' willingness to adopt a hypothetical, AI-enhanced app is measured under three...

Privacy regulations like the General Data Protection Regulation aim to empower consumers with greater transparency and control over their personal data. In response, firms may exercise price discrimination in the form of versioning. This paper studies how these two aspects of privacy regulation...

The emergence of mobile applications (apps) that utilize sharing economy concepts has revolutionized multiple industries, including transportation, accommodation, healthcare, and other sectors. With the nature of massive data collection and sharing policies, these platforms create serious...

We study how privacy regulations impact information transmission. A receiver faces a decision whose payoff depends on an unknown state. A platform sends a message to her given a sensitive and a nonsensitive signal. Privacy loss occurs when the receiver updates about the former. When privacy is...

The introduction of the EU's General Data Protection Regulation (GDPR) in 2018 created conditions that could raise the cost of trading services with the EU, especially where cross-border transfers of personal data are required. This paper examines whether the GDPR has truly affected trade in...
