About the BETA Days 2026
10 April 2026
On 26 and 27 March 2026, BETA members gathered for the latest edition of the BETA Days, a highlight of the laboratory’s calendar. Following Strasbourg in 2025, it was Nancy’s turn to host these two days, which were particularly rich in scientific presentations, discussions and opportunities for socialising.
Research group presentations
A cette occasion, les différents groupes de recherche du BETA ont présenté l’avancée de leurs travaux à travers six interventions.
The morning of 26 March began in the amphitheatre of the Léopold Presidency with a presentation by the 2C2I group. Sandrine Spaeter presented her work on “Insurance and targeted self-insurance of climate-related risks: Corporate financing and optimal arbitrage”, a presentation discussed by Thomas Lanzi.
Presenters from the research groups “Law and Economics” (ED) and “Creativity, Science, and Innovation” (CSI) spoke on Thursday afternoon: Franck Bien on « L’impact du regret-réjouissance sur la demande d’assurance santé dans le cadre de la théorie duale », ond Heman Khouilla on « Déterminants de la complexité économique : effets multi-dimensionnels de la capacité d’absorption et de la qualité institutionnelle ».
Friday’s presentations highlighted the work of Philippe Gillig, for the research group “Cliometrics – History of Economic Thought” (CHPE), « Comment les économistes pensent-ils la transmission patrimoniale ? Une comparaison entre 19ᵉ et 20ᵉ siècle », discussed by Samuel Ferey ; those by Océane Piétri and her co-authors, for the research group « Macroeconomics » (MACRO), “The Aggregate and Distributional Effects of Climate Policy: Adaptation and Mitigation”, discussed by Étienne Lorang ;as well as those by Émilien Macault, for the 2C2I and ED groups, “Stochastic social learning: herding behavior in open systems”, discussed by Sébastien Massoni.
Presentations of cross-cutting research on societal challenges developed at BETA
The BETA Days also provide an opportunity for researchers to present work that illustrates the laboratory’s commitment to addressing major societal issues. This year, two societal challenges were highlighted:
- Health and aging, through the research of Mathieu Lefebvre and Quitterie Roquebert, “Health-State Dependence varies with Income”;
- Gender inequalities with the presentation of Magali Grammare’s project, which aims to give a voice back to the women who “Died for France” between 1914 and 1918.
First-year PhD students in the spotlight
Traditionally, the BETA Days give a central role to newly enrolled PhD students.
This year was no exception. Five special sessions provided an opportunity to discover the backgrounds and thesis projects of: Clémence Barrey, Killian Baué, Louise Boisserie, Tanguy Boulet, Kaouthar Bouzaabia, Riccardo Buso, Émilie Cocco, Georgiana‑Ioana Coroama, Deniz Naz Demirel, Natalie Flämig, Luis Alberto Gomez, Ridwan Mahamoud Mohamed, Nathan Schild, Dorian Simon-Meslet and Jeanne Tétard.
Institutional updates…
As is customary each year, the laboratory’s management took advantage of the BETA Days to hold its General Assembly, providing the entire BETA community with a forum for collective discussion.
This unmissable event provided an opportunity to review the composition of the Board, discuss current structural issues (particularly those relating to the CNRS), revisit the 2026 recruitment campaign, and share best practices, ongoing projects and prospects for the coming months.
… and moments of conviviality
The evening of 26 March, meanwhile, offered a chance to relax and socialise, punctuated by a jazz interlude, which was much appreciated and prepared in-house by Arnaud Daymard, Thomas Lanzi and Clément Mathonnat.
We would like to extend our warmest thanks to everyone who contributed to this 2026 edition: speakers, panellists, PhD students, participants, and the organising team – Magali Jaoul-Grammare, Isabelle Maret, Serge Garcia, Emilien Macault. These Days continue to reflect BETA’s scientific vitality and the richness of its internal exchanges.
