Non-life insurance econometrics
Objectives: In this course, tools are introduced that allow the evaluation of certain risks by taking into account the characteristics and history of the insured. They thus make it possible to take into account the heterogeneity of a portfolio, the evolution of a risk over time, and thus to refine the pricing techniques.
I. Generalized linear model in a priori pricing
- Formulation and estimation of parameters
- Confidence intervals and fit
- Examples and illustrations in pricing
II. Credibility theory, a posteriori pricing
- Bayesian credibility
- Linear credibility
- Hierarchical credibility
- Taking into account a time drift
- Generalities on Markov chains
- Construction of a bonus-malus system
IV. Technical provisions
- Deterministic methods
- Mack’s method and extensions
- Factor methods
- Use of generalized linear models
- Measuring uncertainty in provisions
