“…Furthermore, and to control for potential omitted variable bias (Gujarati and Porter, 2003;Wooldridge, 2010) and to rule out alternative explanations for the mean results (Singh et al, 1986), this study includes an extensive number of control variables, including board characteristics (i.e., board independence, board size, board meeting frequency) and firm-specific characteristics (i.e., firm size, leverage, audit firm size), and ownership structure such as ownership concentration. There is extensive theoretical and empirical literature that suggests these variables can affect CRD (Alsaeed, 2006;Abraham and Cox, 2007;Ismail and Rahman, 2011;Allegrini and Greco, 2013;Ntim et al, 2013;Elshandidy and Neri, 2015;Allini et al, 2016;Al-Maghzom et al, 2016a;Alotaibi and Hussainey, 2016;2018).…”
