This article investigates fve safe-haven asset responses from 2014 to 2022, includ‑ ing the unprecedented COVID-19 crisis, Russian invasion of Ukraine, and sharp US inter‑ est rate increases of 2015 and 2022. We apply the unique approach of the multivariate factor stochastic volatility (MSV)...

This paper examines the long-term dependence between the Polish and German stock markets in terms of industry beta risk estimates according to the Capital Asset Pricing Model (CAPM). The main objective of this research is to compare the Polish and German beta parameters of five Polish and three...

Barndorff-Nielsen and Shephard (2001) proposed a class of stochastic volatility models in which the volatility follows the Ornstein-Uhlenbeck process driven by a positive Levy process without the Gaussian component. The parameter estimation of these models is challenging because the likelihood...
