The Blockchain@X Research Center at École polytechnique invites applications for a postdoctoral fellowship under the supervision of Professor Julien Prat. This full-time, in-person position begins in summer 2026 and is offered for a duration of two years.

The fellowship focuses on research related to the digitalization of finance, with particular emphasis on blockchains, tokenization, and decentralized finance. The successful candidate will benefit from the expertise developed by our research team over the past five years and will have the opportunity to collaborate closely with researchers in economics and computer science who have a well-established track record in digital finance.

The postdoctoral fellow is expected to work closely and actively with all members of the Center. We foster a dedicated and highly interactive research community, with expectations of both collaborative work in small groups and independent research projects.

The primary selection criterion is research excellence in digital finance, along with a clear interest in contributing to the Center’s research agenda. Candidates must have a strong academic background in the field, demonstrated by a PhD in Economics or Finance.

The Blockchain@X Research Center is part of the Institut Polytechnique de Paris. Successful candidates will also be affiliated with CREST (https://crest.science/), a leading research center comprising approximately 50 economists, as well as scholars in statistics, quantitative sociology, and finance, offering a rich and stimulating interdisciplinary research environment.

The Institut Polytechnique de Paris is one of France’s most prestigious higher-education institutions in science and engineering. It brings together École polytechnique, ENSAE Paris, ENSTA Paris, Télécom Paris, Télécom SudParis, and ENPC. Within this ecosystem, the Blockchain@X Research Center at École polytechnique unites researchers in economics and computer science around the study of blockchains and related technologies.

Knowledge of French is not required for any of the positions.

The Department of Economics at the Institut Polytechnique de Paris is committed to diversity and inclusion and seeks candidates who will help create an environment that attracts students of all backgrounds, nationalities, and genders.

· 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).

Job Offer: Economist at I-MIP

The Institute for Macroeconomic and International Policies (I-MIP), located in Paris, is hosted by the Paris School of Economics (PSE) and supported by both PSE and the Center for Economic Research and Applications (CEPREMAP). I-MIP focuses on analyzing and quantitatively assessing public policies using state-of-the-art economic methodologies, with a particular emphasis on numerical techniques.

To reinforce its team, I-MIP is seeking to hire a policy-oriented macroeconomist through a competitive selection process. The ideal candidate should possess expertise in macroeconomics, dynamic and stochastic general equilibrium models (DSGE and HANK), and advanced numerical methods (in Python, Matlab, Dynare,…) for policy analysis. A particular interest in the French economy and the ability to read and understand French are an asset, as the team participates in the annual assessment of the French finance law.

Skills and role of the economist:

- Qualifications: Applicants must hold a PhD in Economics. A strong foundation in macroeconomic modeling, applied econometrics, and programming is essential. Demonstrated expertise in these areas, evidenced by publications in reputable peer-reviewed journals, will be highly valued.

- Responsibilities:

o Collaborate with other I-MIP researchers on policy evaluation projects and contribute to the enhancement and maintenance of I-MIP's quantitative tools, in particular the HANK models of the French economy.

o Engage in teamwork and cooperate with I-MIP economists and affiliated researchers.

o Contribute to the policy evaluation work conducted by I-MIP while also pursuing independent research, benefiting from the stimulating research environment at both PSE and CEPREMAP.

o Actively participate in the activities of the Paris Macro group, including attending and contributing to the PSE Seminar.

This is a permanent (open-ended) position. Compensation will be negotiated based on seniority and prior experience. This position provides a unique opportunity to work on impactful-policy oriented projects while fostering personal research interests in a stimulating academic setting.
