PhD Day

Dear PhD Students and Faculty Members,

We are happy to announce you that Léa and Julien are taking over the PhD Day.

It will be held the 7th of October in Amphi 250 at 9:30,

the size of the amphitéatre will allow us to respect the norms of social distancing.


So far, the planning of the day will be similar to last year’s schedule

with a welcome speech by the new CREST’s director and vice-director,

an introduction of the new comers at CREST:

Professors and PhD candidates will present their research interests during the morning session.

The afternoon session will be dedicated to PhD students

with a presentation of the rules and expectations of the thesis,

presentation of the different fields and opportunities after the PhD.

We look forward to meeting you on this exciting day!


Note that as new professors and PhD candidates are invited to introduce themselves,

it would be nice if the interested parties could signal themselves by return of e-mail.

We would also like to receive the list of their new recruits from the people in charge of the different fields.

Do not hesitate to send us any idea that might contribute to the success of this event and feel free to contact us for any request.

Best regards,

Léa Bou Sleiman, Julien Chhor and Thomas Delemotte

Prof. Xavier d’Haultfoeuille won the 2019 AFSE Malinvaud Prize

June, 2019

Prof. Xavier d’Haultfoeuille won the 2019 AFSE Malinvaud Prize. For is paper “Fuzzy Differences-in-Differences” publised in the Review of Economic Studies (2018), co-authored with Clément de Chaisemartin.

Abstract :
Difference-in-differences (DID) is a method to evaluate the effect of a treatment. In its basic version, a “control group” is untreated at two dates, whereas a “treatment group” becomes fully treated at the second date. However, in many applications of the DID method, the treatment rate only increases more in the treatment group. In such fuzzy designs, a popular estimator of the treatment effect is the DID of the outcome divided by the DID of the treatment. We show that this ratio identifies a local average treatment effect only if the effect of the treatment is stable over time, and if the effect of the treatment is the same in the treatment and in the control group. We then propose two alternative estimands that do not rely on any assumption on treatment effects, and that can be used when the treatment rate does not change over time in the control group. We prove that the corresponding estimators are asymptotically normal. Finally, we use our results to reassess the returns to schooling in Indonesia.

Prof. Francis Kramarz Elected as Society of Labor Economists Fellow

June, 2019

Professor Francis Kramarz has been named a fellow of the Society of Labor Economists (SOLE). The honorary title is given to those who have made “contributions of unusual distinction” to the field of labor economics.

Among these contributions are Kramarz’s work with John Abowd (Cornell and Census) and Margolis (Paris I, CNRS) for the analysis of Linked Employer-Employee data and the so-called AKM model of compensation. This line of research has had an important impact on labor economics as well as fields where bipartite graphs are analyzed (students and schools, patients and hospitals…). Kramarz was also a pioneer in connecting labor markets outcomes with product market competition, including international trade, or in the study of the French minimum wage.

“I am honored to be elected a fellow of the Society of Labor Economists,” Kramarz said. “It is particularly significant to be recognized by the leaders in one’s primary field of research, the existing fellows of the Society.” Indeed, Kramarz is the second French labor economist to receive this distinction (with P.A. Chiappori being the first).

Kramarz, along with Professor Alexandre Mas (Princeton University), was elected by the current SOLE fellows for their career achievements, and their election was announced in the plenary session of the 2019 SOLE Meetings on May 3 in Arlington, Va.
