We study the welfare effects of a merger between ad-funded platforms facing elastic consumer demand. We show that advertising fees as well as quality investment levels by the platforms fall post-merger. Interestingly, despite the lower advertising fees, advertisers may be worse off when their...

This paper introduces modern readers to ‘banking theory’, that is, to the understanding of the banking system that was held by academics and practitioners in the early years of the twentieth century. This theory contrasts with the theoretic framework that views banks as intermediaries that...

This paper introduces a novel mechanism by emphasizing benefits for firms through participation in buyer networks among firms that source the same locally produced inputs. In a first step, we utilize register-based data from Denmark to generate a firm-specific buyer network variable which relies...

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...

This working paper was prepared in 2024 and reviews developments internationally since 2021 relating to the exercise of the right to bargain collectively and the existence of collective agreements among workers in the platform economy. The paper builds upon ILO Working Paper 80, "Realizing the...

The HealthData@EU Central Platform is a pivotal digital system being developed by the European Commission to meet the requirements of the upcoming European Health Data Space Regulation. This platform hosts the Dataset Catalogue, which compiles metadata from member states, European institutions,...

This document is part of the documentation of the HealthData@EU Central Platform Release 4. The system will be developed in 9 releases. The HealthData@EU Central Platform implementation is made available by the European Commission DG SANTE as an open-source. The technical documentation is...

We examine the strategic considerations and effects of product placement services in digital content aggregators, focusing in particular on Spotify’s “Discovery Mode”. Discovery Mode introduces bias in users’ consumption bundle that content providers pay through discounted royalties, and...

This paper proposes a simple yet useful framework for evaluating vertical mergers in digital markets by distinguishing between product-specific and ecosystem-specific network effects. Vis-'a-vis no network effects, product-specific network effects amplify foreclosure and steering incentives, as...

This paper studies biased-manager hiring in a market with network externalities and product compatibility. We show that the aggressivity of a biased manager has a non-linear relationship with product compatibility; however, since both owners want to hire aggressive managers, product...

Previous research on platform ecosystems has mainly focused on the relationships between users, complementors, and platform owners. However, the growing presence of agencies within platform-based markets has received little attention. Complementors are affiliated with an agency or work...

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...

Whereas hydrogen is currently a marginal energy carrier, the aim of the EU is to trigger low-carbon hydrogen production that covers around 10 percent of EU’s energy needs by 2050. If this comes true, it will be an energy revolution. We study competition between green and blue hydrogen by...

We consider a market in which a platform hosts third-party monopolistic complementors. Users are segmented into single-use and multi-use consumers, and services exhibit network externalities. In the agency model, the presence of multi-use consumers leads complementors to set inefficiently high...
