“…Studies in this category mostly explored the direct or moderating effects of board configurations, that is, duality or role separation on firms' financial outcomes using four key sets of measurements, such as return on assets and return on equity (Duru, Iyengar, & Zampelli, 2016; Gaur, Bathula, & Singh, 2015; Hadani, Dahan, & Doh, 2015; Krause et al, 2019; Naseem, Lin, Rehman, Ahmad, & Ali, 2019; Peng, Zhang, & Li, 2007; Pi & Timme, 1993; Ramdani & Witteloostuijn, 2010; Rechner & Dalton, 1991; Syriopoulos & Tsatsaronis, 2012), Tobin's Q (Elsayed, 2007; Jermias & Gani, 2014; Mínguez‐Vera & Martín‐Ugedo, 2010; Poutziouris, Savva, & Hadjielias, 2015; S. Singh, Tabassum, Darwish, & Batsakis, 2018), IPO underpricing or withdrawal (Chahine & Tohmé, 2009; Helbing, Lucey, & Vigne, 2019; Lin & Chuang, 2011), and financial performance in terms of investments and diversifications (Kim et al, 2009; Lim, 2015; Lim & McCann, 2013; D. Singh & Delios, 2017). The majority of these studies agreed that CEO duality is negatively related to firm financial performance (Duru et al, 2016; Grove, Patelli, Victoravich, & Xu, 2011; Jermias & Gani, 2014; Judge, Naoumova, & Koutzevol, 2003; Kaymak & Bektas, 2008; Naseem et al, 2019; Pi & Timme, 1993; Sanan, Jaisinghani, & Yadav, 2019; Schepker et al, 2018) and argued that role separation can facilitate better financial outcomes for companies (de Jonghe, Disli, & Schoors, 2012; De Maere et al, 2014; Li & Naughton, 2007; Rechner & Dalton, 1991; Stockmans, Lybaert, & Voordeckers, 2013; Syriopoulos & Tsatsaronis, 2012).…”
