Gaëtan Fournier

Until August 2026, I am on secondment to the CNRS, assigned to the LYSM in Rome.

I am Maître de Conférences (Assistant Professor) in applied mathematics at Aix-Marseille School of Economics. You can find my CV here. 

My research interests include location games, political economy and repeated games with incomplete information and their applications in theoretical finance.

• General distribution of consumers in pure Hotelling games. International Journal of Game Theory, 84-1, pages 33-59, 2019.

• Approachability with constraints with Eden Kuperwasser, Orin Munk, Eilon Solan and Avishay Weinbaum, European Journal of Operational Research, Volume 292, 2021.

• Location games with references with Amaury Francou. Games and Economic Behavior, Volume 142, 2023.

Work in progress:

Outreach:

• Hotelling games on networks: Diablogues économiques, also in french or in video (in french).

• Location games with references: Dialogues économiques, also in french or in video (in french).

• Location games with references: AMSE research highlights.

• Strategic flip-flopping in political competition: AMSE reseach highlights.

• Price dynamics on a risk averse market with asymmetric information: 5&5 (PSE) and Le Cercle-Les Échos.

I am co-supervising Alexandre Arnout’s PhD thesis with Antonin Macé.
