In the era of increasingly widespread use of electronic communication tools, constant growth of e-commerce turnover is hardly surprising. One of its mechanisms are online auctions whose turnover, on a global scale, is enormous. Consequently, there is a need for theoretical research to facilitate...

Various techniques of scale parameter estimation have been proposed in the case of alpha stable distributions. In the paper, the authors present an estimation technique that involves the k-th record theory. Although this theory is over 40 years old, its implementation in the classical extreme...

The paper presents a new method that allows adding the environmental factor (the green factor) to systemic risk measurement, as existing systemic risk measures do not quantify this risk explicitly. We propose a method to extract the green factor from the environmental score (E-score) and augment...

We investigate if all European IBOR rates are similarly susceptibile to turbulence as LIBOR rates. We also analyze systemic risk spillovers between different IBOR rates in Europe and between these rates and the studied banking systems between 2006 and now. We employ a set of innovations in...
