A Reexamination of Audit Fees for Initial Audit Engagements in the Post-SOX Period
研究了2007至2010年后SOX时期，四大与非四大会计师事务所在首次审计中是否仍存在低价揽客行为，发现审计费用折扣依然普遍，对监管机构加强审计独立性有参考价值。
SUMMARY: On August 16, 2011, the Public Company Accounting Oversight Board (PCAOB) issued a concept release seeking comments on ways to enhance auditor independence. The Board notes that higher failure rates in new audit engagements might be linked to unrealistic pricing. The Board's concern is that a new auditor might be more susceptible to management pressure if initial-year audit fees are set artificially low. Prior to the Sarbanes-Oxley Act (SOX) of 2002, empirical evidence shows that auditors discounted their initial-year audit fees. This practice, known as lowballing, was expected to decrease significantly after the enactment of SOX. Indeed, findings in Huang, Raghunandan, and Rama (2009) seem to confirm that Big 4 auditors charged a fee premium on new auditor-client relationships in 2006. However, it is not clear if more recent post-SOX initial-year audits are free of lowballing. We investigate whether lowballing exists in new auditor-client relationships in an “extended” post-SOX environment for the years 2007 to 2010. Our results suggest that both Big 4 and non-Big 4 accounting firms discounted their initial-year audit fees during our sample period (2007–2010). These findings should be of interest to the PCAOB as it searches for ways to bolster auditor independence. Data Availability: Available from public sources.
