Économie de la concurrence (Competition Economics)
Licence 2 · Spring semester · 20h lectures · Taught in French
An introduction to the economics of competition policy. The course reviews the main competition authorities (US, EU, French) and traces how economic thinking has shaped competition law, before turning to the two central categories of anticompetitive conduct: cartels and vertical agreements (Article 101 TFEU) and abuse of dominance (Article 102 TFEU). Landmark cases and current enforcement news structure the discussion throughout.
Économie industrielle (Industrial Economics)
Licence 3 · Fall semester · 24h lectures + 10.5h tutorials · Taught in French
A first full course in industrial organization, building on the microeconomics sequence. It covers market definition and the measurement of market power, static imperfect competition (Cournot, Bertrand with differentiated products, Hotelling and Salop), then dynamic extensions through sequential choices - location, quality, capacity, commitment - and free-entry models, from contestable markets to natural oligopolies. The course closes with an introduction to two-sided markets and platform pricing.
Fusions et acquisitions (Mergers and Acquisitions)
Master 1 · Fall semester · 20h lectures · Taught in French
An economic analysis of external growth strategies. The course examines the determinants of merger activity and the empirical evidence on merger effectiveness, then moves to merger control and the information asymmetry facing competition authorities, including remedy design. It closes on two current questions: the relationship between mergers and R&D, and the employment effects of consolidation. Students work on a merger case of their choice and are introduced to difference-in-differences estimation through an applied research example.
Concurrence et réglementation (Competition and Regulation)
Master 1 · Spring semester · 20h lectures · Taught in French
Where competition policy ends and sector regulation begins. Working across the US, EU, and French levels, the course covers merger control and remedies, then the public-economics rationale for regulatory intervention - externalities, public goods, natural monopolies - and the main regulatory instruments and institutional designs. A final chapter is devoted to the interface between competition policy and environmental policy, drawing on cases where the environmental dimension proved decisive.
Réglementation et marché (Regulation and Markets)
Master 1 · Spring semester · 20h lectures + 10h tutorials · Taught in French
The theoretical counterpart to the applied competition courses. Students learn to model merger and cartel strategies under imperfect competition and to assess their welfare consequences, along with the instruments available to control them. The course provides the formal foundation needed for later empirical work on market outcomes. Main textbook: Belleflamme and Peitz, Industrial Organization: Markets and Strategies.
Regulation and the Digital Era
Master 2 · Fall semester · Taught in English · Co-taught with Godefroy de Boiscuille and Frédéric Marty
How digital platforms, market concentration, and new business models are redrawing the boundary between competition policy and sector regulation. Combining industrial organization, competition law, and digital economics, the course addresses market power, data governance, innovation, and sustainability through case studies - the DMA and DSA, Big Tech antitrust proceedings, multi-sided markets, algorithms, and AI. The central question is when ex-ante regulatory tools complement, and when they substitute for, ex-post competition enforcement. Format: lectures, guided readings, and student presentations.
I supervise Master’s theses and doctoral research in industrial organization, competition policy, regulation, and transport economics. Students interested in working with me are welcome to get in touch.
