“…Finally, in studying the effect of peer group overlap on firms' competitive aggressiveness, we combine insights from accounting and strategic management. While competitive actions trigger many accounting-related issues, such as earnings management (e.g., Burgstahler and Dichev, 1997;Roychowdhury, 2006) and disclosure (e.g., Ali, Klasa, Yeung, 2014;Glaeser, 2018;Park, Sani, Shroff and White, 2019), the accounting literature has largely ignored the effect of accountingrelated choices on such actions. Given that competitive aggressiveness is an established and validated construct (see, e.g., Ferrier, 2001;Ferrier and Lyon, 2004;Ferrier et al, 1999;Nadkarni et al, 2016;Ndofor et al, 2011), this construct provides amply opportunity for future accounting research.…”
