The local Hurst exponent, a measure employed to detect the presence of dependence in a time series, may also be used to investigate the source of intraday variation observed in the returns in foreign exchange markets. Given that changes in the local Hurst exponent may be due to either a...

All banks must hold capital equal to the minimum regulatory requirement. However, in many cases the level of regulatory capital diverges from the actual (economic) capital held by banks. A bank's actual capital is typically linked to a target credit rating, which is in turn determined by the...

Extreme value theory (EVT) is regularly put forward by academics, practitioners and banking regulators as a methodology for measuring the likelihood of operational risk losses that have a very low probability of occurrence, but which have the potential for catastrophic outcomes in terms of...

It is somewhat ironic that while the major focus of regulators and institutions in the financial services sector over recent years has been on developing models for measuring and managing credit risk, most of the large losses in financial institutions over this time have been sourced to...

This paper develops a framework for examining the impact of changes in the solvency standard of a bank (target credit rating) on the pricing of bank assets. We show that the decision of a bank to increase its solvency standard increases the price of bank assets to the extent that a bank prices...

Within the context of a banking institution, economic capital is a statistical measure of the amount of resources required to meet unexpected losses over a specified time period and specified level of certainty. The amount of economic capital held by banks is thus a function of their target...

In June 2004 the Basel Committee on Banking Supervision of the Bank for International Settlements issued its revised framework for the international convergence of capital measurement and capital standards. In developing the framework the Committee has sought to determine risk-sensitive capital...

An increase in the credit rating on an organisation?s debt is generally perceived positively, as higher credit ratings are, in the main, associated with lower perceived volatility in the market value of the assets of the entity that has issued the debt. If banks price their assets to realise a...

The strategic importance attained by the notion of corporate social responsibility (CSR) over the past two decades has encouraged a greater understanding of the historical processes through which it has evolved and been consolidated in the corporate world. However, the role played by...

The research presented in this thesis aims to improve our knowledge regarding the impact of privatisation and deregulation of public service type infrastructure industries. In recent years, Australia's industry reform policies have critically relied on rapid deregulation of major utilities such...
