The shape and dynamics of the yield curve provide useful information in the analysis of current economic and financial developments, and market expectations. This article describes the key theoretical factors affecting the yield curve and examines their role in the developments in advanced and...

Our article discusses the 2012 European Union regulation on naked CDS positions and its effects on CDS market developments in Central and Eastern European EU Member States. Although following the adoption of the regulation in March, an adjustment period of nearly seven months was available until...

We have studied the magnetic properties of a mixed ferro–ferrimagnet composed of three different metal ions with spins 12,1, and 32 which includes both ferromagnetic and antiferromagnetic interactions. The system is considered in the frame of an Ising model in the effective-field theory with...

The mixed spin-1 and spin-32 Ising ferrimagnetic system with different anisotropies is studied within the mean-field theory based on Bogoliubov inequality for the Gibbs free energy. Global phase diagrams are obtained in the temperature-anisotropy plane. In particular we find first-order...

In the paper, we study the projections of the real exchange rate dynamics onto the string-like topology. Our approach is inspired by the contemporary movements in the string theory. The string map of data is defined here by the boundary conditions, characteristic length, real valued and the...

Many studies have shown that there are good reasons to claim very low predictability of currency returns; nevertheless, the deviations from true randomness exist which have potential predictive and prognostic power [J. James, Simple trend-following strategies in currency trading, Quantitative...
