To understand how to design a theoretical model of a general equilibrium, a model that must remain simple and at the same time provide answers to relevant economic questions.
To be able to model imperfections in labor and product markets and to analyze some macroeconomic consequences (the modeling is mathematical but it is the economic intuitions that are important).
The course seeks to show how small deviations from the assumptions of perfect competition (the presence of economies of scale) allow for the understanding of various macroeconomic phenomena.
The individual power of firms in product and labor markets gives them the ability to change prices and wages.
By aggregating the individual behaviors of firms, we develop a general equilibrium model (a model of monopolistic competition) that allows us to better understand observations such as regional inequalities or discrimination.
This type of modeling based on imperfect competition shows that a government can be advised to intervene in a structural way in the economy.

Oral exam, closed book.
The material covers all the slides available on Webcampus.
The objective of the exam is not to be able to reproduce the (many) calculations, ... but to be able to explain the logic of the reasoning.
● Which modeling is adequate to explain which phenomenon?
● Why is it adequate?
● What is the structure of the modeling?
