Applied macroeconomic modelling: Policies, the business cycle, and the green transition 


Objectifs du cours

Macroeconometric and DSGE models are among the most commonly used models in ministries of finance, central banks and international organizations in order to evaluate economic policies. This course introduces students to the construction, estimation and use of DSGE and macroeconometric models for policy purposes. It will in particular focus on how to bring economic theory to a practical model and how to use such models to produce recommendations for policymakers. Some applications will be presented for instance in relation to the green transition.

Acquis du cours

At the end of the course students will be able to understand the functioning of standard macroeconometric models usually used in ministries of finance, central banks and international organizations. They will notably be able to read, analyze and criticize model outputs. Students will be able to download macroeconomic data, estimate the deep parameters of DSGE models, provide policy counterfactual analysis.
