Course Description

The course Competition and Big Tech Regulation in Europe was designed and developed as a single, coherent teaching module consisting of thirteen lectures. The curriculum blends legal, economic, and policy perspectives to explain how the EU addresses market power in digital markets through:

• Ex-post enforcement (antitrust and merger control under EU competition law), and
• Ex-ante regulation (the Digital Markets Act), increasingly complemented by platform and data governance instruments.

The curriculum uses real enforcement trajectories (Google, Apple, Amazon, Meta) to show how legal doctrines (dominance, self-preferencing, tying, leveraging, access, data advantages) map to platform business models and market structures (multi-sided markets, ecosystems, network effects).

The design of the curriculum ensured:

• Progression from core competition law concepts to DMA logic and detailed case studies.
• Integration of antitrust enforcement with DMA compliance and “state of play” in EU digital regulation.
• Policy realism, linking enforcement tools to remedies, compliance programmes, and institutional strategy.
• Comparative awareness, situating EU approaches against the US and other jurisdictions, and introducing global regulatory convergence/divergence.
