We present a geometric approach to discrete time multiperiod mean variance portfolio opti-mization that largely simplifies the mathematical analysis and the economic interpretation of such model settings. We show that multiperiod mean variance optimal policies can be decom-posed in an orthogonal...

This paper compares the pricing and hedging performance of the LMM model against two spot-ratemodels, namely Hull-White and Black-Karasinski, and the more recent Swap Market Model from anAsset-Liability-Management (ALM) perspective. In contrast to previous studies in the literature, ouremphasis...

In this paper, we compare two one-factor short rate models: the Hull White model and the Black-Karasinski model. Despite their inherent shortcomings the short rate models are being used quiteextensively by the practitioners for risk-management purposes. The research, as part of...

This paper tests the co-terminal swap market model (SMM) pricing and hedging performance onBermudan swaptions. To our knowledge, the drift for SMM is derived explicitly for the first timehere, and the procedures for calibration and simulation using a collection of forward swap rates arealso...

This paper analyzes the emergence of systemic risk in a network model of interconnected bank balance sheets. Given a shock to asset values of one or several banks, systemic risk in the form of multiple bank defaults depends on the strength of balance sheets and asset market liquidity. The price...

The development of financial markets in the emerging market economies of Eastern Europe is considered one of the crucial elements of the overall reform process. Under central planning, banks used to be passive recipients of orders from the planners; they did not engage in any credit screening...

In this paper we have developed a financial model of the non-life insurer to provide assistance for the management of the insurance company in making decisions on product, investment and reinsurance mix. The model is based on portfolio theory and recognizes the stochastic nature of and the...
