Marie Laclau is a CNRS researcher in Economics and an Associate Professor of Economics and Decision Sciences at HEC Paris. A specialist in strategic communication, she develops models to help organizations better transmit, share, or filter information.
Marie Laclau’s research is aimed at decision-makers operating in decentralized environments, where coordination relies on repeated and often imperfect interactions.
She applies game theory to collective decision-making to tackle these issues: How should communication be structured within an organization? What protocols can ensure cooperation? She also examines the long-term impact of communication strategies.
At the intersection of economics and computer science, she designs protocols that meet specific cryptographic requirements—essential for understanding decentralized systems.
Marie Laclau regularly publishes in leading academic journals, including Games and Economic Behavior, Mathematics of Operations Research, Theoretical Economics, and the Journal of Economic Theory, and serves as associate editor for Theory and Decision. Her research is also covered in The Conversation and Les Echos (in French).
A PhD graduate at HEC Paris, she earned the Best Thesis Award from the French Economic Association. She then held a postdoctoral fellowship and lectured at Yale University before joining the Paris School of Economics, and later HEC Paris.
