CREST Conference on Risk & Insurance 14-15 sep 2023


The objective of the conference is to bring together leading academic scientists, researchers, and research scholars to present and exchange their research results on economic and financial decisions under risk, insurance markets and related public policies. It will be also a tribute to Professor Pierre Picard, an outstanding researcher of the field, who is Emeritus Professor at École polytechnique since September 2021.

This conference is organized as a workshop, based on plenary sessions held at ENSAE (Sep. 14) and Maison internationale (Cité internationale de Paris, Sep. 15), each presentation (12 in total) being made by a leading scientist. Presentations will represent the diversity of research on economic and financial decisions under risk, insurance markets and related public policies. All presentations will be made by invited speakers.

Date: September 14 and 15, 2023.

Participation to the conference is free, but registration is required. Please, click here to register.

PhD in economics: cohesion and multidisciplinarity


At the end of the year, the doctoral students in CREST’s economics cluster organized a series of seminars for first-year doctoral students.

Cohesion & multidisciplinarity

Cohesion between doctoral students is essential. It fosters collaboration, the exchange of ideas and mutual support, creating an environment conducive to learning. Peer solidarity allows to share experiences, solve problems in groups and develop crucial skills. By fostering a team spirit, the cohesion between doctoral students contributes to their personal development and success in their doctoral studies.

These seminars provide another opportunity for first-year doctoral students to present their research. They highlight the theme of their research, as well as the specific questions they are tackling, and the methodology envisaged throughout their doctorate.

CREST doctoral students and researchers are invited to take in these seminars, where their experience in presenting their research enables young doctoral students to practice presenting their project clearly and concisely to people outside the field, thus providing a fresh and stimulating perspective.

The sessions also facilitate the establishment of links with researchers working in similar fields, giving PhD students the opportunity to obtain advice based on the experience of these researchers.

By emphasizing multidisciplinary within the same cluster, these seminars encourage doctoral students to benefit from reflections from the literature and approaches from other fields of research within CREST. This approach stimulates multidisciplinary reflection, enriching the research work of each student.
