Economics serving society

Opening Economics Chair


Hermès and Paris School of Economics have created the "Opening Economics" Research Chair.
Led by Jean-Olivier Hairault and Jean-Marc Tallon, respectively Director and Head of Research at PSE, this chair has the ambitious objective of opening up economics to and through other disciplines.

Several activities are on the chair’s agenda:


The goal of the "Opening Economics" Research Chair is to allow economists to respond in creative and effective ways to the major questions of our times, by integrating two observations: that current challenges, complex and multifaceted as they are, demand an approach that transcends disciplinary boundaries, and that economics research must be renewed by advances made in other, related disciplines.

The chair is supported by the scientific leaders of four current research projects:

  • An integrated approach of economic decisions”. Holders: Nicolas Jacquemet and Jean-Marc Tallon. In order to understand the complexity and the constraints of the human mind in the face of change, researchers in behavioural economics and psychology work with cognitivist scientists and neurobiologists. The range of subjects in the field include memory, the emotions, perceptions, learning, and (in)attention.
  • Society and Environment”. Holders: Lucas Chancel and François Libois. Climate change, biodiversity loss, soil erosion, multiform pollutions... The social and economic sciences, together with the environmental sciences, have a major rôle to play in better identifying and measuring not only the vulnerabilities posed by these processes but also the opportunities, in order to design appropriate responses to them.
  • Economics – Philosophy”. Holders: Marc Fleurbaey and Jean-François Laslier. The potentially fruitful exchanges between economics and philosophy range over several subjects – social justice, collective choices and democracy, the rationality of decisions – and aim to produce responses to the challenges facing our societies that are democratic, inclusive and ethical.
  • "Urban economics, history and society”. Holders: Camille Hémet. Two dimensions seem particularly promising for advancing our studies of urban questions, which have been developing rapidly in recent years: the historical and social dimensions, and the interaction between the two. These elements are found at the crossroads of several disciplines, especially economics, history, sociology and geography.

Since 1837, Hermès has maintained its artisanal model and its humanist values. The freedom to create, the constant search for the most beautiful materials, the transmission of excellence in craftsmanship, and the aesthetics of function form the singularity of Hermès, a fashion house where objects are created to last. An independent family concern, Hermès is committed to keeping the bulk of its production in France, at its 51 factories and production sites, while developing a network of more than 330 shops in 45 countries. The group employs almost 17,000 people around the world, of which almost 10,600 work in France, including more than 5,600 artisans.* Since 2013, Hermès has been directed by Axel Dumas, one of the 6th generation of directors. Since 2008, the Hermès Foundation has supported projects in the fields of artistic creation, the training and transmission of artistry and skills, biodiversity and preservation of the environment.
