5. CONCLUSION AND FUTURE OPPORTUNITIES
This paper reviews research in accounting and finance concerning data analytics and big data in order to better understand the use of big data techniques in auditing. We first point out the origins of big data techniques in the multivariate statistical literature and then categorize big data accounting and finance research under several research groupings. Our analysis shows that, in addition to auditing, there are influential papers across financial distress modelling, financial fraud modelling, and stock market prediction and quantitative modelling. We review each of these streams of research to ascertain their main contributions and to outline knowledge gaps. Unlike financial distress and financial fraud modelling, auditing has been slow to make use of big data techniques. Auditing would greatly benefit from embracing the use of big data techniques, regardless of whether client firms are using them or not. Findings from accounting and finance research suggest combining multiple big data models instead of applying an individual model, and using big data models to complement human experts.
