TSE Digital Center


The rapid development of digital technology is generating new challenges and a fundamental transformation in the daily lives of citizens and organizations, with a significant impact on individuals, governments and businesses around the world. TSE undertakes research that helps public and private sector organizations understand the opportunities and risks of the digital economy. 

Based in particular on the research activities conducted since 2015 in the framework of the Jean-Jacques Laffont Digital Chair, TSE created in 2018 a research center of excellence dedicated to the digital economy, bringing together the expertise, financial support and knowledge of private and public partners. The ambition is to establish one of the best digital economy research centers in Europe and to exercise intellectual leadership in this field.

Main activities 

Scientific production:

  • Development of new knowledge resulting in academic publications
  • Organization of scientific conferences and seminars

Dissemination of economic knowledge:

  • Production of outreach materials and the organization of events meant to inform practitioners, policy makers or a wider audience
  • Participation of researchers in the public debate in France and internationally

Research focuses

Digital platforms

  • Objective: Research in this program is centered on understanding the business models of platforms and their impact on society and welfare. We hope to shed light on the functioning of platform markets and offer policy recommendations regarding the regulation of such markets. 
  • Program leader: Doh-Shin Jeon works on industrial organization, IT, intellectual property, economics of science.

Analytics and economics of Big Data

  • Objective: With the help of mathematicians, our economists develop optimization techniques, applied econometric tools and game-theory concepts that help us to handle high-dimensional random phenomena. We study data-related issues such as privacy protection, data markets, and the impact of data on competition. 
  • Program leader: Sébastien Gadat works on applied mathematics involved in machine learning and artificial intelligence, with an emphasis on statistics and stochastic on-line optimization algorithms.

Artificial intelligence and society

  • Objective: Our objective is to investigate the ethical expectations that citizens and consumers hold to smooth the transition to the new AI society. We conduct research in the high-stakes domain of algorithmic justice and study areas in which AI and powerful algorithms can redesign the social fabric. 
  • Program leader: Jean-François Bonnefon works on decision-making and moral preferences. He explores the kind of ethics people want for self-driving cars and other machines.

Financial technologies and digital markets

  • Objective: This program analyzes the implications of key features of FinTech and cryptocurrencies, and their impact on social welfare. We study the design of markets, institutions and regulations to mitigate coordination problems, information asymmetries and other market failures.
  • Program leader: Christophe Bisière works on FinTech, blockchain and cryptocurrencies.

Intellectual property in the digital economy

  • Objective: The goal of this initiative is to offer a better understanding of intellectual property protection and transfer in the digital economy. We analyze patent litigation involving IoT players and the licensing of intellectual property to manufacturers of connected devices. Our researchers assess the economic effects of making platforms liable for intellectual property infringements by third-party users. 
  • Program leader: Yassine Lefouili works on law and economics of intellectual property, competition policy and digital economics.
