Risk, efficiency and industry dynamics in the Australian banking sector

This thesis applies innovative methods to the efficiency and productivity analysis of the Australian banking system. Key areas of investigation include the impact of regulatory reforms on bank performance, the impact of firm entry and exit on industry productivity and the changing nature of banking and the role of risk in measuring bank value-added. The latter leads to the construction of a new bank production model, emphasising risk management as part of a bank’s value-added. As such, the proposed bank output framework views risk as a productive service, rather than a bad output or externality, which is often assumed in the literature. Aided with this new framework, several refinements are suggested for the treatment and measurement of bank output by researchers and statistical agencies. A unified regulatory framework combined with a greater level of harmonisation in rules in the Australian banking sector, has meant that a pooled analysis of all deposit-taking institutions has become feasible for the first time. With an enlarged dataset new insights are gained into the relative performance of deposit-taking institutions in Australia. The results challenge commonly held views of bank efficiency and the relevance of scale, size and incumbency when measuring bank efficiency. The new definition of bank output is also applied across the sector using econometric and non-parametric techniques to gauge productivity. Problems with balanced data sets and aggregation of firm level productivity are examined. A new approach to decomposing aggregate industry level productivity is introduced based on strong axiomatic grounds and its ability to attribute productivity between continuing, exiting and entering firms. The technique is applied for the first time and uses the newly developed bank output production model. The analysis provides key information on the relative performance of firms in the Australian banking sector.
