“…Some researchers use accounting method variables as a proxy for the earnings quality, which is essentially only a signal of earnings quality. Other researchers use variables other than accounting methods as a proxy for accounting earnings quality, which in essence only shows signals about earnings quality, for example auditor quality variables (Okolie, 2014), broad voluntary expressions (Fernando et al, 2018), accounting conservatism (Heflin et al, 2015), earnings management (Kwag & Stephens, 2010;Suprianto et al, 2017), auditor industry specialization (Okolie, 2014), corporate governance (Ahmed, 2013;Mukhtaruddin et al, 2019), and sustainability concerns (Kim et al, 2018). This study uses a sustainability concern variable as a signal of accounting earnings quality as carried out by Kim et al (2018).…”
