Pol Consentino (alumni) receives the 2025 AFET–La Fabrique de la Cité Prize in Transport Economics
Pol Consentino (CES PhD 2025), postdoctoral researcher at Université Paris-Dauphine, has been awarded the 2025 AFET–La Fabrique de la Cité Prize in Transport Economics.
The AFET Prize recognizes the best paper presented at the association’s annual conference by a doctoral researcher or by a researcher within five years of completing their PhD.
The prize was awarded on 19 November at the third AFET conference. The recipients of this second edition of the AFET–La Fabrique de la Cité Prize in Transport Economics are Pol Consentino and Pascale Champalaune for their paper entitled “Commuting, Air Quality and Welfare in the Paris Region.” Their research evaluates the impact of the Grand Paris Express on modal shift and land values, with a particular focus on air quality.
The award-winning paper provides an in-depth analysis of the effects of public transport investments on air quality and welfare in the Paris region. Its methodological originality lies, first, in the rigorous use of high-resolution data to measure the localized effects of tramway line openings between 2008 and 2018 on modal shares, local pollution (PM2.5), and housing prices. Second, the study develops a spatial equilibrium model that incorporates several innovative features, including the effects of pollution on residential amenities and firm productivity, as well as endogenous migration responses to changes in accessibility and environmental quality.
Together, these estimates yield rich results that shed light on the impacts of tramways, the Grand Paris Express, and new tramway lines on public transport modal share, reductions in local pollution, real estate prices, welfare gains, and their distribution across social groups.
