Online ratings emerge from a multi-stage process that can systematically distort their informational content. We develop a unified framework decomposing the rating process into distinct components: experienced quality (driven by intrinsic quality, seller effort, and price), expectations formed...

This paper develops a theory of bargaining in firm-to-firm trade with two-sided market power. The framework accommodates flexible market structures, yielding analytical expressions for pair-specific markups and pass-through elasticities. In U.S. import data, we estimate strong importer...

The Digital Services Act (DSA) marks a paradigmatic shift in platform governance, introducing mechanisms like the Statement of Reasons (SoRs) database to foster transparency and observability of platforms' content moderation practices. This study investigates the DSA Transparency Database as a...

We investigate how new land releases affect the pricing of nearby parcels in a standardised virtual real estate market. Using 9920 secondary-market transactions from The Sandbox on the Ethereum blockchain, we implement a difference-in-differences design around expansion announcements. Nearby...

The article presents the uptake and development of instant payments across countries representing various geographies with diverse economic and social backgrounds. It identifies the critical success factors for the rapid adoption of instant payments.This study features five country cases where...

In many industries, platforms compete with incumbents that are open to all consumers, whereas platforms require user affiliation. Consequently, platforms face two layers of competition: for the market, to attract users, and in the market, to compete with incumbents. We develop a dynamic model...

The decision delivered by the European Court of Justice in Android Auto may represent a watershed moment in competition policy for digital markets. By requiring dominant platforms to accommodate third-party requests to enable interoperability, the judgment could significantly affect their design...

We incorporate the endogenous feedback loop at the core of the seminal Schelling (1969) model of segregation into a dynamic model of neighborhood choice and use it to study the forces that shaped racial and income segregation in the San Francisco Bay area from 1990 to 2004. Such an analysis...

Online platforms have evolved into powerful programmable architectures that enable heterogeneous groups of autonomous but interdependent users to interact. Based on a stratified sample of 1,380 companies from a newly developed enterprise survey in Austria, the analysis aims to reduce the lack of...

In this special issue, we refer to "content moderation" as the multi-dimensional process through which content produced by users is monitored, filtered, ordered, enhanced, monetised or deleted on social media platforms. This process encompasses a great diversity of actors who develop specific...

Market definition is essential for antitrust analysis, but challenging in settings with network effects, where substitution patterns depend on changes in network size. To address this challenge, we conduct an incentivized experiment to measure substitution patterns for TikTok, a popular social...

Marketplace platforms are central players in online retail and are in an advantageous position to leverage data generated by third-party sellers. This paper analyzes how a platform's encroachment decision - whether to enter its marketplace as a direct competitor - is shaped by regulations that...

The impact of current changes in technology, society, and the environment demand innovative research approaches that can accurately capture the increasing complexity of modern geographic data. To this end, this article provides an introduction to the use and implementation of spatial network...
