Objectives
The main goal of this subject is to acquire special competences in actuarial science for which the main methodologies used regard the Utility Theory and the Risk Theory.
Learning outcomes and competences
The student should learn concepts of Utility Theory and Insurance and be able to use the techniques associated to the modeling of individual and collective risk for a single and extended period.
