The term of audit expectation gap (AEG) was created nearly 50 years ago and has received the attention of many researchers. Despite a lot of research on AEG, the method of measuring AEG remains controversial. The number of studies which propose the method of measuring AEG is limited and there are many problems when applying these methods in empirical studies. Inherited from previous studies, this paper aims to develop a new method of measuring AEG and proves it by the results from the application of this method in empirical research in Vietnam. The article achieves two important results: (1) Proposing a new method of measuring AEG based on the Porter’s definition and structure of AEG; and (2) Proving the results from the application of the new method for measuring AEG by conducting empirical research in Vietnam.

This study aims to identify the determinants of the expectation gap in fraud detection between internal auditors and bankers in Indonesia. The shift in the internal audit task in the banking sector can cause the hole in audit expectations to widen. This research uses qualitative methods with an interpretive paradigm which is rarely done by previous research. The results of interviews with internal audit work units and bank managers from 4 state-owned and private banks indicate a gap in audit expectations regarding the responsibilities between internal auditors and bankers, especially in carrying out the function of examining and detecting fraud. This study recommends the financial services authorities and bank leaders be able to improve education regarding anti-fraud policies to stakeholders, especially in terms of a clear division of tasks in fraud detection in the banking sector.
