“…Recent studies on spillover effects and contagion (e.g., Apergis et al, 2019 ; Bayona & Peia, 2020 ; Bhanot et al, 2014 ; Bucci, Torre La, Liuzzi, & Marsiglio, 2019 ; Kalbaska & Gatkowski, 2012 ; Leventides, Loukaki, & Papavassiliou, 2019 ; Piccotti, 2017 ; Reboredo et al, 2016 ) tested various modifications of covolatility approaches to check for cross-country spillover effects. In the same framework, studies as Dungey et al (2020) , Guidolin, Hansen, and Pedio (2019) , Collet and Ielpo (2018) , Alter and Beyer (2014) , Claeys and Vasicek (2014) , and Jiang, Konstantinidi, and Skiadopoulos (2012) focused on VAR models to conclude for financial contagion.…”
