The arbitrage theory of the term structure of interest rates serves as the main tool for the pricing and hedging of interest rate dependent derivatives. It provides the basis for the risk management of banks and financial institutions with regard to interest-rate-dependent derivatives such as options on bonds, financial futures and interest rates (caps, floors and swaptions).
The stochastic modeling of the dynamics of a financial market and the understanding of risk management is an important subject within the education program in economics and mathematics. Strengthening the ability of economic students to understand the basic concepts in probability theory and their knowledge of stochastic process up to martingale properties is a difficult task. On the other side the knowledge about financial products, the trading motives and restrictions within a financial market are usually not considered within the mathematical education program. Emphasizing these aspects the textbook [1] serves as an attempt to combine these different areas.
Non-standard financial products with broken compounding periods, time delayed payment dates, barrier conditions or individual exercise opportunities are frequently offered by financial institutions. The valuation of these products is derived by numerical procedures. A more robust approach relies on super hedging ideas. The research agenda is to extent the ideas of super hedging and uncertain volatility to interest rate dependent claims.
Equity linked life and pension insurance contracts are related to financial risk (interest rate, price, index) as well as to non-financial risk (e.g. death and survival risk, premature exercise). The valuation and hedging of these contracts is related to the diversification technique within a cohort of insured persons and to the dynamic duplication by the financial market. Periodic premium and long time to maturity complicates the hedging problem. The research project considers robust contract specifications in the sense of super hedging strategies and model independency. The solution involves the contract design as well as the construction of the underlying financial portfolio.
The public debate has pushed compensation policy like Executives Stock Options (ESOs) at the forefront. An on-going discussion is whether ESOs have in fact encouraged the managers to take on too large risks which might improve their own benefits but jeopardize the firm. Sustainability and incentive compatibility are the main qualitative keywords. The approach is to consider non-traditional performance-based ESOs which discourage managers from excessive risk taking.
