Bruno Jullien

Bruno Jullien serves as Senior Researcher at CNRS and Toulouse School of Economics (TSE), holding affiliations with MaCCI, CEPR, CESIfo, and CMPO as a Fellow. He currently leads research under an Advanced ERC Grant.

His academic foundation includes degrees from Ecole Polytechnique, ENSAE, and EHESS, culminating in a Harvard PhD in economics. Leadership roles encompass Directorship of GREMAQ and dual appointments as Deputy/Scientific Director of TSE.

Research centers on industrial organization with specialized focus in network economics, multi-sided platforms, and competition policy. His work critically examines digital market structures, pricing mechanisms, and regulatory frameworks for technology-driven industries, bridging theoretical models with real-world antitrust applications.

Recent publications reveal dominant trends in platform economics and competition policy, particularly analyzing personalized pricing algorithms, two-sided market dynamics, merger impacts on innovation, and privacy-security tradeoffs. These works consistently integrate microeconomic theory with contemporary regulatory challenges in digital ecosystems.

Key recognitions include:

• Fellow of the Econometric Society
• Fellow of MaCCI
• Fellow of CEPR
• Fellow of CESIfo
• Fellow of CMPO
• Advanced ERC Grant recipient

Policy engagement features membership in the European Commission's Economic Advisory Group on Competition Policy and Steering Committees of the Association of Competition Economics and EARIE. His ERC-funded research drives current investigations into platform market regulation while past leadership at TSE/GREMAQ established foundational institutional frameworks for economic research.

Through TSE's research ecosystem, Jullien contributes to collaborative networks analyzing digital transformation's economic implications, particularly influencing competition policy development for multi-sided platform markets across European regulatory bodies.
