L’Institut Polytechnique de Paris is an alliance between five engineering schools (Ecole polytechnique, ENSAE Paris, ENSTA Paris, Télécom Paris, Télécom SudParis). Our joint Department of Economics is located on the top floor of the ENSAE Paris building.

All members of the department belong to the research center CREST.

The economy is an essential lever of today’s society and understanding the phenomena that govern it at different levels is crucial for describing and analyzing the production, exchange and consumption of goods and services. Research in economics and quantitative sociology at the Institut Polytechnique de Paris is characterized by a strong attachment to quantitative methods, data culture, mathematical modeling, and the constant back-and-forth between models and empirical facts to analyze concrete economic and social issues.

The research activities of the Institut Polytechnique de Paris in economics and quantitative sociology are structured around four areas:

  • Macroeconomics and labor economics: fluctuations, probability and finance, business, political economy, unemployment theory, economics of education
  • Theoretical and applied microeconomics: industrial economics, competition, social choice theory, organization of games and economic modeling
  • Economics of sustainable development: economics of climate change, sustainable finance and responsible investment, environmental and energy economics
  • Quantitative sociology: mobility and social inequalities, demography, socio-genomics, sociology of political, economic and cultural practices, computational social sciences
