Course Details:

Lecturer: Jeffrey Collamore; ph.: 3532 0782; e-mail:

Lectures: Tuesday 10-12 in Aud. 7; Thursday 10-12 in Aud. 7.
Exercises: Thursday 13-16 in Auditorium Syd, Nørre Alle 51.

Evaluation: Your grade will be based entirely on a three-hour written exam (open book).

Prerequisites: Together with the course "Quantitative Risk Management (QRM)," this forms a two-part sequence. Roughly, the prerequisites for the sequence are an introductory, bachelor-level course in non-life insurance mathematics and an introductory measure-theoretic course in probability theory.

Course material: H. Schmidli, Lecture Notes on FM2, Ch. 1-3.
J. F. Collamore, Supplementary notes on ruin with stochastic investements and related problems.
J. Paulsen, Claim reservation in non-life insurance. 30 pp.

Course description: In the first part of the course, we will focus on ruin theory. Emphasis here will be given to the proofs of the Lundberg bound (via martingale techniques), the Cramer-Lundberg estimate (via the renewal theorem), Laplace transform techniques, subexponential claims, the renewal risk model, and the numerical technique of importance sampling. We will also discuss a few modern topics; in particular, ruin with investments and its connection to certain problems in financial time series modeling. In the final part of the course, we will focus on claims reserving.
