“…Auditor size indicates the large scale income and organization of the public accountant firm, which is now called Big 4 (including its affiliation), comprising PricewaterhouseCoopers (PwC), Deloitte Touche Tohmatsu (Deloitte), Ernst and Young (EY), and Klynveld Peat Marwick Goerdeler KPMG). Previous research had documented the correlation between audit quality being measured by a measurement proxy of a Big 4 auditor (Al-Thuneibat et al, 2011;Alzoubi, 2016;Francis and Wang, 2008;Houqe et al, 2015;Kabir et al, 2011;Wang et al, 2014;Zakaria and Daud, 2013) and the earnings quality measured by a certain proxy such as earnings response coefficient (Alzoubi, 2016;Houqe et al, 2015;Teoh and Wong, 1993;Wang et al, 2014;Zakaria and Daud, 2013), discretionary accruals (Alzoubi, 2016), and abnormal accruals (Francis and Wang, 2008;Wang et al, 2014). The Big 4 auditors have a better audit quality than small or non-Big 4 auditors arguably because large audit firms have greater resources, knowledge, technical experience, capacity, and reputation compared to small audit firms.…”
