Recent regulatory initiatives targeting the statutory audit regime support the notion that the audit expectation gap is still a driver of change. This study seeks to analyse causes of the gap as well as the impact of proposed changes to the current statutory audit regime using an approach that differs from those used in prior literature. This approach allows us to attribute the audit expectation gap under the current regime to a failure of the public, the standard-setter, or the auditor. Based on the questionnaire survey conducted in 2011 in Germany, we find the public to have exaggerated expectations of auditors' responsibility under current standards. Other causes of the gap relate to the public's difficulty in assessing the performance of auditors, but also to deficiencies in auditors' performance. In addition, we find that auditors are not fully aware of their responsibilities. Increasing the information content of the audit opinion is expected to narrow the gap. By contrast, recent proposed changes, such as mandatory rotation and a ban on non-audit services, may reduce the gap only to a lesser extent. Overall, it can be shown that the audit expectation gap is by its nature a persistent phenomenon comprising complex social aspects and interactions with changing accounting requirements, such as increase uncertainties in accounting estimates.
