Description: This paper presents a unifying non-Bayesian statistical method for incorporating prior information into the determination of probability distributions and other finite measures and develops the statistical properties of this method together with actuarial applications. A discussion of the paper follows. From Transactions of Society of Actuaries 1991, Vol. 43.

Description: Presented at May 2002 Spring Meeting. Our lecturer presents findings from a research project relating to the Cox, Ingersoll & Ross model of interest rates, including an effective way of pricing general interest rate derivatives and pricing bonds.

Description: The main goal of the paper is to make the next edition of the textbook, 'Actuarial Mathematics' slightly better regarding the Risk Theory part. From Actuarial Research Clearing House 1993. VOL. 2.

Description: This paper proposes to put the environment into financial markets. It explains how to do it, and why the financial approach is practically the only one able to stop and invert environmental degradation. The author concentrates on deforestation which is the largest environmental problem in the third world, and explains how to start the project and what kind of optimization problems should be solved for applications of the project.

Description: The main objective of this study is to analyze and control a surplus dependent risk process, where larger surpluses allow for a wider underwriting policy. We focus here mostly on the diffusion approximation of the risk process. The results are derived in two papers Brownian motion in Risk Theory, submitted for publication, and Surplus dependent risk processes defined by stochastic differential equations, in preparation. We only include here a long summary of these papers.
