It's been a priviledge to serve in this position (if sometimes exhausting after 935 new submissions ...). The greatest part of the job is seeing how many people in the profession take the role of refereeing so diligently, and constructively, and work hard to build this community.

Junior researchers can submit a paper in economics of discrimination, gender, education & organizational #economics. Submit by 31 August. cepr.org/events/ghaza... #EconSky
To honour the memory of Ghazala Azmat, the Department of Economics of SciencesPo is creating an award in her name.

Ghazala made important contributions in a large number of fields, spanning the economics of discrimination, gender, education and organizational economics. The award will promote work in those fields by young scholars.

The first edition of this award will consist of a 5,000 euro prize for the best paper in this set of fields by junior researchers. The selection of the laureate will be carried out by a scientific committee composed of Pierre Cahuc, Alan Manning and Barbara Petrongolo.

Eligibility for the prize requires that all authors have obtained their PhD after 1 September 2018. Papers written jointly with more senior researchers will not be considered.

The prize will be awarded at SciencesPo during the event organised in memory of Ghazala on 10 December 2025. One of the authors of the prize winning paper will present the work at this event.

Applications must be submitted by 31 August 2025.
