Description: This is an abstract of the paper A Second Order SDE for the Force of Interest. In this paper, the author models the force of interest by a linear second order stochastic differential equation.

Description: This is the abstract of the paper Hedging of Insurance Contracts. ls the tinting of liabilities e.g. the IBNR case irrelevant to investment decisions in an insurance company? Even in the extreme case of independence between claim developments and movements in the financial markets, the assumption of constant insurers' absolute measure of risk aversion is necessary for a positive answer to the initial question.

Description: This is the abstract of the paper Risk Classification by Fuzzy Cluster. In this paper an algorithm for risk classification is proposed. This algorithm is based on the concepts of fuzzy cluster. We test our algorithm with two examples, the results are very promising.

Description: This is the abstract of the paper A Space Marching Finite Difference Algorithm for Valuing American. In this paper, the author considers the problem of valuating American options written on assets that pay continuous dividends with unknown optimal exercise boundary. The numerical solution of the associated free boundary value problem is investigated. This research has been partialy supported by the actuarial faculty fund at the Ohio State University.
