CEO duality (Board_D) is a dichotomous variable that equals 1 when the CEO is also the board chair and 0 when the two roles are separated (Tahir et al, 2020;Turrent et al, 2020;Ain et al, 2021;Dissanayake and Dissabandara, 2021); Board size (Board_S) is measured by the total number of directors on the board (Tahir et al, 2020;Ain et al, 2021;Dissanayake and Dissabandara, 2021); Board independence (Board_I) is measured by the ratio of the number of independent directors to board size (Su and Fung, 2013;Maaloul et al, 2018) [2]; Firm size (Firm_S) is measured by the natural logarithm of total assets El Ammari, 2008, 2009;Pérez et al, 2015;Ciftci et al, 2019;Maaloul et al, 2018;Chertel et al, 2020;Niazia et al, 2021;El Ammari, 2021b); and Leverage ratio (Lev_R) is measured by the ratio of the book value of total debt (short-and long-term) to the book value of total assets (Li et al, 2008;Chen et al, 2011;Bliss and Gul, 2012;Su and Fung, 2013;Pérez et al, 2015;Bansal and Sharma, 2016;Ciftci et al, 2019;Niazia et al, 2021).…”
