“…Previous external audit research (e.g., DeAngelo, 1981; Prawitt, Sharp, & Wood, 2012) recognizes that the type of auditor plays a significant role in the quality of audit and considers the big N firms as high‐quality auditors who can constrain earnings manipulation. Recent research (e.g., Boone, Khurana, & Raman, 2010; Cassell, Giroux, Myers, & Omer, 2013; Kurniawati, Van Cauwenberge, & Vander Bauwhede, 2019) also differentiates between nonbig4 firms and describes second‐tier audit firms such as Grant and BDO as high‐quality providers who are able to curb irregular accounting practices. In the context of IAF, Prawitt, Sharp, and Wood (2012) find that big N audit firms who perform both external audit and IAF are less likely to be associated with the risk of fraudulent financial statements.…”
