Abuse of Dominance in the Funeral Industry

Franziska Guggi’s work on abuse of dominance in the funeral industry, which she previously presented at the ASCOLA conference in Porto in 2022, was just published. It analyses abuse of dominance in the funeral industry against the background of the essential facilities doctrine. In 2022, Franziska was awarded the Linda-Rauter-Prize by the Faculty of Law of the University of Graz for this work, which is based on her Master thesis. The prize goes to the most outstanding theses in the areas of comparative law, European law, and international law. The contribution is available here:


Computational Antitrust Tools to Detect RPM

Computational antitrust tools can help competition authorities in the detection of antitrust infringements. However, these tools require the availability of suitable data sets in order to produce reliable results. In their proof-of-concept study carried out within the realm of the DataComp project, Jan Amthauer, Jürgen Fleiß, Franziska Guggi and Vicky Robertson focus on the area of resale price maintenance. By applying web scraping to price data for washing machines in Austria from a publicly accessible price comparison website, they compiled a comprehensive data set for a period of nearly three months. Visualised with the help of interactive dashboards, this data could then be analysed using various benchmarks in order to determine whether individual washing machine manufacturers and their retailers may be engaging in resale price maintenance. They conclude that the availability of data is a strong driver for research into and the application of computational antitrust tools. If market data were publicly accessible and provided in a more structured format, researchers and competition enforcers could develop ever-more refined computational antitrust applications that would, ultimately, safeguard competition in markets.

How to Analyse the Microsoft/Activision Merger

Fabian Ziermann’s article on Microsoft’s pending acquisition of Activision Blizzard was just published in the Journal of European Competition Law & Practice as part of the third Rubén Perea Award. In his article, Fabian addresses questions regarding the delineation of video game genre markets and potential harms to innovation in game genres, game ecosystems, and metaverse development. These issues may have been overlooked by the Competition & Markets Authority and the European Commission in their respective decisions to prohibit and approve the acquisition. Fabian argues that this neglect could result in a false positive, three times the acquisition value of Facebook/WhatsApp. The article can be accessed here.

Abuse of Dominance

Anti-Competitive Rebates

In the Research Handbook on Abuse of Dominance and Monopolization, published by Edward Elgar in April 2023, Vicky Robertson contributed a chapter on rebates, detailing the antitrust rules applicable to loyalty or fidelity rebate schemes under EU competition and US antitrust law. The chapter finds that antitrust liability for a dominant company will more readily be established in the EU, where the applicability of economics-based tests is still being navigated. In the US, rebates by a monopoly player will usually be found to be anti-competitive where they constitute predatory pricing, although they might also run into antitrust liability where they constitute exclusive dealing arrangements. This divergence can be explained by the different ideological underpinnings in the two jurisdictions. Overall, however, the (case) law on loyalty rebates is still in a state of flux in both jurisdictions. In recent years, both jurisdictions have gradually moved to a little more convergence in their treatment of exclusivity rebates. At this point, however, both the US Supreme Court and the European Court of Justice will need to weigh in on the future of the antitrust assessment of loyalty-inducing rebates.

The Handbook is edited by Pınar Akman, Or Brook (both University of Leeds) and Konstantinos Stylianou (University of Glasgow). It can be found here.

Computer Law & Security Review

Computational Antitrust: The Status Quo

Cartels and other anti-competitive behaviour by companies have a tremendously negative impact on the economy and, ultimately, on consumers. To detect such anti-competitive behaviour, competition authorities need reliable tools. Recently, new data-driven approaches have started to emerge in the area of computational antitrust that can complement already established tools, such as leniency programs. In this systematic review of case studies, Jan Amthauer, Jürgen Fleiß, Franziska Guggi and Vicky Robertson show how data-driven approaches can be used to detect real-world antitrust violations. Relying on statistical analysis or machine learning, ever more sophisticated methods have been developed and applied to real-world scenarios to identify whether an antitrust infringement has taken place. The review suggests that the approaches already applied in case studies have become more complex and more sophisticated over time, and may also be transferrable to further types of cases. While computational tools may not yet be ready to take over antitrust enforcement, they are ready to be employed more fully.

This is the first paper of the DataComp project, published in volume 49 of the Computer Law & Security Review. It is available in open access here:

New Textbook

New Textbook on EU Competition Law

Edited by Aleš Ferčič of the University of Maribor, a new textbook on European Union Competition Law was just published by Europa Law Publishing. This comprehensive textbook covering all major aspects of this intriguing part of Union law. It was prepared by a group of distinguished specialists from European universities, including Nataša Samec Berghaus, Stefan Krenn, Pieter Van Cleynenbreugel, José Caramelo Gomes, Martina Repas and Matjaž Tratnik. Vicky Robertson contributed a chapter on market definition. The book covers the various pillars of EU competition law that prevent unlawful restrictions of competition within the internal  market. The focus is on anti-competitive agreements, abuses of a dominant position,  mergers and state aid measures. Both substantive and procedural issues are covered, including not only public but also private enforcement. In addition, introductory chapters allow readers to immerse themselves in general concepts of EU competition law.

World Competition

Book Review

In the latest issue of World Competition, Klaudia Majcher published a review of the book ‘How Big Barons Smash Innovation: And How to Strike Back’ co-authored by Ariel Ezrachi and Maurice E. Stucke. This timely book brings into the spotlight how toxic innovations flourish in the digital economy and what should be done to enable the emergence of valuable innovations, particularly from an antitrust perspective. Klaudia’s review is based on her comments provided at the launch of Ezrachi’s and Stucke’s book that took place during the Vienna Competition Law Days in September 2022.

Antitrust in data

Antitrust in Data-Driven Markets: Austria

Together with Gerhard Fussenegger (bpv Hügel), Vicky Robertson authored a report on how Austria deals with data-driven markets under competition law. The report was written for the Ligue internationale du droit de la concurrence (LIDC) and published by Springer. It details the Austrian transaction value threshold for mergers, which was introduced in 2017 and aimed at catching digital mergers of competition law interest, as well as outlining some major trends in competition law enforcement in digital markets.

The Market Power of Big Tech

In an interview with Austrian newspaper Salzburger Nachrichten, Vicky Robertson discusses the market power of Big Tech, their anti-competitive behaviour, the importance of data for these markets, and the merger strategies that allow online conglomerates to sweep rising start-ups off the market.
