Bachelor's degree Économie et gestionUE Microeconomics


We will examine problems in which optimising consumers or firms interact strategically and non-cooperatively, where information might be private, where some actions might not be observed, or where agents have to search for the best price or a job.

Course outline :

(1) Revision of the theory of the consumer and the firm : Constrained optimisation and the Lagrangean, value functions, duality, Slutsky decomposition.

(2) Strategic Interactions : Monopoly, Oligopoly, Cournot and Bertrand competition.

(3) Introduction to the economics of information : Hidden information (asymmetric information), hidden action (moral hazard).

(4) Decentralised markets : Introduction to Search Theory. Application to models of the labour market.

(5) Introduction to Game Theory : Normal form games, extensive form games, equilibrium notions.

Professional skills

We will develop the ability to formalise economic problems using appropriate models, and to solve these in order to make predictions about behaviour using an appropriate notion of an equilibrium. Often, the problem at hand involves optimising consumers or firms that interact strategically and non-cooperatively.
