“…In addition, there are studies showing duality to be positively related to firm performance (Berkman et al, 2010; Peng, 2004; Peng et al, 2007; Tian & Lau, 2001), contrary to the agency prediction about the impact of CEO duality. Although several studies find that duality is negatively related to board independence and executive turnover (Chen & Al-Najjar, 2012; Firth et al, 2006b; Shen & Lin, 2009; You & Du, 2012; Zhang, Ji, Tao, & Wang, 2011), their findings may have been an artifact of ownership concentration given its significant impact on the composition of the boards of directors (Chen et al, 2011; Li et al, 2012; Su et al, 2008). Overall, there is little evidence that duality increases CEO power and weakens corporate governance in the listed firms in China.…”
