COURS enseigné en FRANCAIS
The main objective of the course is to introduce students to the concept of risk and to explain how uncertainty modifies the choices of individuals and societies. At the end of the course, the students will be able to distinguish between risk lover, risk neutral and risk adverse attitudes in the different theories of risk.
The course will present the evolution of the theory of risk from the notion of expected value to the concept of expected utility. A great attention will be given to the prospect theory and to alternatives approach to risk management, such as the relational theory.
Syllabus:

Modalités
The course uses a mixed method of frontal lessons, experiments, games, and group’s works. The students will be solicited to take part in the lessons by providing their opinions on the paradox of risk theory, by betting on risky lotteries and by discussing their preference in terms of risk attitudes.
The notes will depend on the active participation of students in the lectures. Many different activities will give to students the possibility to gain additional points for the final note. 50% of the final note will come from the mid-term written exam. The remaining 50% will come from the final exam, which will take the form of a group presentation.
