“…Some studies have used other measures of interconnectedness as a link in the bank network; these include credit default swap contracts (Ballester, Casu, & González-Urteaga, 2016;Gandy & Veraart, 2019;Kanno, 2018;Peltonen, Scheicher, & Vuillemey, 2014), and cross-ownership of equity shares (Cao, Gregory-Smith, & Montagnoli, 2018;Dastkhan & Gharneh, 2016, 2018Elliott et al, 2014;Elsinger, 2009). However, bank network, as defined in our study, is based on economic connections identified from stock market data (i.e., correlation network of stock return dynamics), as in Diebold and Yilmaz (2014), Brunetti et al (2015), and Candelon, Ferrara, and Joëts (2018). This view is generally accepted in the literature, as high correlations in the bank equity sector are the main source of systemic risk in the bank network.…”
