Postdoctoral Fellowships (x2) – Microeconomic Theory, Behavioral Economics

The LEMMA laboratory of the Université Paris-Panthéon-Assas invites applicants within the following fields:

• Microeconomic Theory / Decision Theory / Game Theory

• Behavioral Economics / Cognitive Neuroscience

Requirements

Candidates must have earned a PhD degree in Economics or related fields by the time of appointment, and no later than September 1st, 2026.

Candidates must demonstrate research excellence of the highest international caliber in one of the listed fields. Evidence may include an innovative job market paper, high-quality working papers, publications in top or field-leading journals, strong referee letters, a compelling research statement, major conference presentations, and notable awards.

Research and teaching interests should be in line with our laboratory strengths. Candidates should motivate their application considering the laboratory’s overall research profile and location.

Position details:

· Starting date September 1st, 2026.

· Duration: 1+1 (a third year is envisaged for the position in behavioral economics/cognitive neuroscience, subject to performance evaluation).

· Salary: around 2500€ / month net.

· French language is not required.

About the projects

The two postdoctoral positions are financed by prof. Lorenzo Bastianello within the CPJ « Risques nouveaux et Dynamiques d’émergence » (ISI-RIDER), and prof. Andrea FM Martinangeli within the project “BREAKING – Behavioural Responses to Inequality as a Social Ranking” (funded by the ANR - National Research Agency).

· Postdoctoral Position in Microeconomic Theory. The successful candidate will work with Prof. Lorenzo Bastianello as part of the CPJ “Risques nouveaux et Dynamiques d’émergence” (ISI-RIDER) project. We seek applicants with a strong mathematical background and research interests in microeconomic theory, particularly in decision theory and game theory. The position focuses on modeling decision-making under severe uncertainty, that is, in contexts characterized by emerging risks, limited data, and contradictory information. The project aims to produce at least one publication in a top-ranked journal.

· Postdoctoral Position in Behavioral Economics / Cognitive Neuroscience. The successful candidate will work with the project team (in close collaboration with AFM Martinangeli and/or Jean-Claude Dreher, or other team members) to develop behavioral studies allowing for cognitive analyses and which, in a second phase, can be extended to model-based fMRI investigations. The candidates’ research interests should align with the scope of the project. An overview of the projects’ scope and aims can be found on the project website: https://sites.google.com/view/project-breaking/home?authuser=1

Articles produced as part of the project are expected to be published in both economics and neurocognitive science top outlets.

Candidates can apply to one project only and should explicitly articulate how they can contribute to and strengthen the project. Any package not explicitly and clearly specifying which position the candidate is applying for will not be considered.

How to apply

The deadline for applications is February 28th 2026. Applications must be submitted online at https://econjobmarket.org/.

A complete application must include a cover letter; a current curriculum vitae; a research statement outlining current and future research interests and how the candidate’s research profile matches the fields listed in the posting; a job market paper; and three recent letters of reference (on letterhead, dated, and signed) uploaded directly by referees. Other working papers or publications are optional. Candidates are asked to specify for which project they apply.

Interviews will be conducted online, in March. We will invite a limited number of candidates for virtual job talks in early April.

About the Lemma Laboratory

The Laboratory of Mathematical Economics and Applied Microeconomics (LEMMA) was founded in 2003 by economists, mathematicians and computer scientists within the University Paris-Panthéon-Assas. LEMMA hosts about thirty permanent members (including numerous international researchers) and fifteen PhD students. Its work is organized around two research areas: Games and Decision and Applied Microeconomics. The Games and Decision area covers decision and social choice (preferences, aggregation, voting), games, learning and investment (strategic behavior under uncertainty), interdisciplinary approaches to game theory (mathematics, biology, philosophy). Applied Microeconomics focuses on monetary and banking economics (emerging payment systems, search models), evaluation of public policies and corporate practices (health, motivation, inequality), political economy and development (combining economic and political science).

For questions about these positions, please email project leaders professors Lorenzo Bastianello ([email protected]) and Andrea Martinangeli ([email protected]).
