Risk Theory - 3A/MS/M2

Objective

The purpose of this course is to present the basic mathematical concepts of damage insurance. The objective of Risk Theory is to provide theoretical models of the cost and number of claims in order to deduce the associated risk and to price insurance contracts.
At the end of this course, students should be able to : 

• Use the individual and collective model of claims occurrence in non-life insurance.
• Apply the collective model to insurance
• Understanding the Poisson process and its application in ruin theory
   

Planning

1. Preliminaries - Reminders, generating functions. 
2. Insurance models - Individual model, collective model.
3. Risk comparison.
4. Premium principle and risk measurement.
5. Theory of ruin - Poisson's process, Lundberg's model, probability of ruin.
