At the annual conference of the Academic Society for Competition Law (ASCOLA), which took place in London from 1 to 3 July 2026, The Competition Law Hub was represented by Franziska Guggi, Klaudia Majcher and Vicky Robertson. Franziska presented a chapter of her PhD in computational antitrust – stay tuned! Klaudia presented her working paper on epistemic welfare in competition law. Vicky presented a chapter of her forthcoming book, dealing with multi-stakeholder engagement in digital competition law. She also chaired a session on antitrust foundations, and discussed Richard Bunworth’s paper on the impact of Irish merger control.

ASCOLA 2026 was also a great opportunity to catch up with former visiting fellows of The Hub, including Belle Beems, Thomas Cheng, Helena Drewes, Eva Fischer and Wendy Ng.

AI & Competition

ComplawAdmin — Wed, 08 Jul 2026 08:07:43 +0000

On 30 June 2026, Vicky Robertson participated in a Roundtable on AI and Competition, hosted by Ariel Ezrachi at Pembroke College, Oxford. It was an excellent opportunity to push the current boundaries for engagement with the many ongoing developments in AI and ecosystem envelopment. In particular, it was highlighted how various forms of AI-driven misinformation need to be countered, including through competition law. Remedies, it was emphasised, need to be carefully drafted and addressed in order to be successful – and should not only come as an afterthought.

Computational Antitrust in Action?

ComplawAdmin — Fri, 12 Jun 2026 07:22:48 +0000

At The Hub’s Jour fixe, Fanni Tuominen (Graz University of Technology) presented her research into the use of data-driven tools in the enforcement of EU competition law by the European Commission, the General Court and the Court of Justice. She created an interconnected dataset that allows for navigating instances in which the authority and the courts relied on keywords associated with computational antitrust, and also looked into ways in which topic modelling could be applied to legal documents. She carried out her interdisciplinary research with Jürgen Fleiß, Vicky Robertson and Dominik Kowald.

Merger Guidance on Democracy

ComplawAdmin — Tue, 09 Jun 2026 09:57:38 +0000

Although the European Union’s draft Merger Guidelines acknowledge that consolidation in digital platforms can harm the democratic process, they need to up their efforts to protect media competition and a quality public sphere. In a new blogpost on ProMarket, Vicky Robertson discusses three steps that could help EU merger control support liberal democracy: (i) The European Commission should assume its role as a central actor when it comes to merger control of digital media platforms; (ii) non-price parameters relevant for media pluralism should be made actionable in theories of harm; and (iii) synergies between the European Media Freedom Act and EU merger control should be identified and leveraged. The blogpost can be found here. It is part of a symposium on the draft EU Merger Guidelines.

Steering and User Choice in the DMA

ComplawAdmin — Wed, 29 Apr 2026 07:49:18 +0000

Vicky Robertson and David Führer just published a working paper version of their analysis of Articles 5(4) and 5(5) Digital Markets Act (DMA) on SSRN. These two provisions enshrine business users’ right to steer their customers away from gatekeepers’ app stores, as well as users’ right to access content they acquired off a core platform service. Articles 5(4) and 5(5) DMA need to be seen against the background of the anti-steering provisions typically included in various application stores. These have already been subject to antitrust enforcement and have now also come under DMA scrutiny in the Apple App Store (non-compliance) decision of 2025.

The contribution is forthcoming in a comprehensive commentary on the Digital Markets Act, edited by Ioannis Kokkoris.

Klaudia Majcher’s book on ‘Coherence between Data Protection and Competition Law in Digital Markets’ was awarded the Irena & Jerzy Wiszniewski Foundation Award for the best scholarly work in the field of trademarks, patents and competition law. Published by Oxford University Press in 2023, when Klaudia was Assistant Professor at WU Vienna, the book argues for a more integrated approach to enforcing competition law and data protection in digital markets.

The award was presented on 19 March 2026 during the conference ‘The Regulation of Markets in Defence of Democratic Principles’ at the University of Warsaw, co-organised by the Centre for Antitrust and Regulatory Studies, the Irena & Jerzy Wiszniewski Foundation, and the Polish Academy of Sciences’ Institute of Law Studies.

Many congratulations, Klaudia!

The Workshop was hosted by the Czech Competition Authority UOHS.

Vicky contributed to the panel on remedies and commitments in unilateral conduct cases and shared her research on data-driven tools for competition enforcement, focusing on data-driven monitoring of remedies, its opportunities and challenges. The panel was moderated by Rita Leandro Vasconcelos (Pérez-Llorca) and included fellow panelists Alexandre Barreto (Brazilian Competition Authority CADE), Marjorie Holmes (Reed Smith) and Friso Bostoen (University of Tilburg). Her contribution was based on her research on algorithmic remedies (with Jana Lasser; see here) as well as her research on data-driven tools in antitrust enforcement (with Jürgen Fleiß, Jan Amthauer, Franziska Guggi, Dominik Kowald and Valentin Forster; see here, here, here and here).

At the 6^th plenary meeting of the High-Level Group for the DMA on 20 March 2026, Vicky Robertson was invited as an academic expert to contribute to a discussion on the future of digital regulation in the European Union. In her talk, she discussed her research on coherence in EU platform regulation (with Klaudia Majcher, see here), the external benchmark approach (with Ariel Ezrachi, see here) and on the complementarity of EU competition law and the DMA (see here). The Hub’s former visiting research fellow Belle Beems and Orla Lynskey also spoke about issues affecting the future of digital regulation, including institutional coherence and the collapse of boundaries between legal fields.
