Econometrics aims to understand and quantify relationships between economic variables, through the combined study of mathematical statistics, economic models, and economic data.
This includes development of new statistical tests and estimation procedures, and the study of their properties (econometric theory), as well as the application of such tools to economic data, in order to convert qualitative statements and forecasts into quantitative ones (applied econometrics).

The current research activities of the DEVI econometrics group include microeconometrics, empirical industrial organization, partial identification, and the econometrics of networks. Aside from its methodological importance, this work can provide valuable insight for policymakers and decision-makers in industry.
Particular applications developed by members of the group are the study of airline networks, the analysis of airline entry decisions, and the pricing schemes of airlines.
