Back to the future for competition policy

The frontiers of competition policy are rapidly expanding driven by deglobalization, inflation, the rise of big tech and the green transition. 

As competition authorities and anti-trust regulators navigate these fields, a revival of traditional methodologies and approaches is gaining traction. 

Recent years have seen new regulatory regimes for subsidies and digital markets which draw on existing competition policy frameworks; however, the consistency of competition policy enforcement across jurisdictions remains a question. 

Compliance requirements have also become more complex as many major jurisdictions retreat from economic effects-based approaches towards more form-based and ex-ante regulation creating an uncertain environment for international businesses and investors.

This conference, hosted in person and held under the Chatham House Rule, explores emerging competition policy trends and their impact on global innovation, investment and supply chain stability.

Subsidies, sustainability and supply chain stability

  • Do new regulatory regimes for subsidies represent equal treatment for all or discriminatory targeting of particular jurisdictions? 

  • How should the European Commission account for other jurisdictions’ policy objectives such as supply chain stability and will other jurisdictions retaliate with their own regulation of EU subsidies?

  • What theories of harm could be grounds for intervention in mergers and public tenders and what economic evidence will be relevant?

  • To what extent are subsidies for sustainability and supply chain stability objectives consistent with international trade rules? 

  • Could subsidies under the Inflation Reduction Act and the EU’s response be challenged under the World Trade Organization and/or the EU Foreign Subsidies Regulation?
