Evaluating Extremal Dependence In Stock Markets Using Extreme Value Theory, Abhay K. Singh, David E. Allen, Robert J. Powell Jan 2011

Evaluating Extremal Dependence In Stock Markets Using Extreme Value Theory, Abhay K. Singh, David E. Allen, Robert J. Powell

Estimation of tail dependence between financial assets plays a vital role in various aspects of financial risk modelling including portfolio theory and hedging amongst others. Extreme Value Theory (EVT) that provides well established methods for univariate and multivariate tail distributions which are useful for forecasting financial risk or modelling the tail dependence of risky assets. This paper uses nonparametric measures based on bivariate EVT to investigate asymptotic dependence and estimate the degree of tail dependence of the ASX-All Ordinaries daily returns with four other international markets, viz., the S&P-500, Nikkei-225, DAX-30 and Heng-Seng for both right and left tails of …

Value At Risk Estimation Using Extreme Value Theory, Abhay K. Singh, David E. Allen, Robert J. Powell

A common assumption in quantitative financial risk modelling is the distributional assumption of normality in the asset’s return series, which makes modelling easy but proves to be inefficient if the data exhibit extreme tails. When dealing with extreme financial events like the Global Financial Crisis of 2007-2008 while quantifying extreme market risk, Extreme Value Theory (EVT) proves to be a natural statistical modelling technique of interest. Extreme Value Theory provides well established statistical models for the computation of extreme risk measures like the Return Level, Value at Risk and Expected Shortfall. In this paper we apply Univariate Extreme Value Theory …

The phenomenon of the occurrence of rare yet extreme events, “Black Swans” in Taleb’s terminology, seems to be more apparent in financial markets around the globe. This means there is not only a need to design proper risk modelling techniques which can predict the probability of risky events in normal market conditions but also a requirement for tools which can assess the probabilities of rare financial events; like the recent Global Financial Crisis (2007-2008). An obvious candidate, when dealing with extreme financial events and the quantification of extreme market risk is Extreme Value Theory (EVT). This proves to be a …


How Green Are Climate Change Issues?: An Auditor's Perspective, Maya Purushothaman, Ross Taplin Jan 2011

How Green Are Climate Change Issues?: An Auditor's Perspective, Maya Purushothaman, Ross Taplin

Research outputs 2011

Climate change and carbon emissions have become an important issue for companies, not only if companies are to maintain legitimacy as good corporate citizens but also financially with the regulation of carbon emissions and the impending introduction of the Australian Emission Trading Scheme (AETS). This paper investigates the role of financial auditors in the climate change debate. Content analysis of the websites of fifteen large auditors in Australia reveals different reactions to this issue, from reacting to proposed legislation to proposing initiatives proactively and providing guidelines for companies. Analysis of the websites from a random sample of companies audited by …
