Detection of Management Fraud: A Neural Network Approach

The detection of management fraud is an important issue facing the auditing profession. A major contributor to this issue is the Loebbecke and Willingham 1988 conceptual model for the detection of management fraud. A cascaded Logit approach using the Loebbecke and Willingham model was developed in Bell et al. 1993. The present study offers an alternative approach using Artificial Neural Networks ANNs. This paper develops a successful discriminator of management fraud using both the generalized adaptive neural network architectures GANNA and the Adaptive Logic Network ALN approaches to designing neural networks. The discriminant functions can distinguish between fraudulent and non-fraudulent companies with superior accuracy to the cascaded Logit results of Bell et al. 1993. Finally, the discriminant function provides a parsimonious set of questions useful for detecting management fraud.
