Audit Firm Size, Audit Fee, Audit Reputation and Audit Quality: The Case of Listed Companies in Vietnam

Audit quality is considered as an essential factor affecting the reliability of financial information. The aim of this study is to assess the effects of audit firm characteristics, including audit reputation, audit fees and audit firm size, on audit quality. A sample of 192 companies listed on Hanoi and Ho Chi Minh Stock Exchange for the period of 2006-2014 was selected. Multiple regression was used to analyze the data. The findings show that Big 4 auditors in Vietnam provide high audit quality than non-Big 4 auditors. Interestingly, in Vietnam context, except for the audit firms in the Big 4 group, the findings suggest that smaller audit firms provide better audit quality. Additionally, the results reveal that the more audit fees the auditors receive, the lower audit quality they provide. The critical role of audit quality has attracted significantly scholarly attention, however, prior studies have mainly focused on firms in developed countries. Little is known about audit quality in an emerging economy context such as Vietnam. This study adds to the limited number of studies on audit quality of listed companies in emerging economies.
