Do Nonparametric Measures Of Extreme Equity Risk Change The Parametric Ordinal Ranking? Evidence From Asia, Robert J. Powell, Duc H. Vo., Thach N. Pham
Do Nonparametric Measures Of Extreme Equity Risk Change The Parametric Ordinal Ranking? Evidence From Asia, Robert J. Powell, Duc H. Vo., Thach N. Pham
Research outputs 2014 to 2021
There has been much discussion in the literature about how central measures of equity risk such as standard deviation fail to account for extreme tail risk of equities. Similarly, parametric measures of value at risk (VaR) may also fail to account for extreme risk as they assume a normal distribution which is often not the case in practice. Nonparametric measures of extreme risk such as nonparametric VaR and conditional value at risk (CVaR) have often been found to overcome this problem by measuring actual tail risk without applying any predetermined assumptions. However, this article argues that it is not just …
The Determinants Of Capital Structure: Evidence From Thai Banks, David E. Allen, Napaporn Nilapornkul, Robert Powell
The Determinants Of Capital Structure: Evidence From Thai Banks, David E. Allen, Napaporn Nilapornkul, Robert Powell
Research outputs 2013
The aim of this study is to examine the determinants of the capital structure of Thai banks. The data spans a ten year period from 1999 – 2008. The differentiation point of this study is that, whereas most studies on capital structure focus predominantly on internal bank variables, this study, in addition to internal variables includes market-based risk variables. A range of market-based default and value at risk variables were considered which were then narrowed down to improve the model. Fixed effects panel data analysis is employed, with both market and book leverage used as dependent variables. The Thai bank …
Measuring Real Capital Adequacy In Extreme Economic Conditions: An Examination Of Swiss Banking Sector, David E. Allen, Robert Powell
Measuring Real Capital Adequacy In Extreme Economic Conditions: An Examination Of Swiss Banking Sector, David E. Allen, Robert Powell
Research outputs 2011
The global financial crisis (GFC) has placed the creditworthiness of banks under intense scrutiny. In particular, capital adequacy has been called into question. Current capital requirements make no allowance for capital erosion caused by movements in the market value of assets. This paper examines default probabilities of Swiss banks under extreme conditions using structural modeling techniques. Conditional Value at Risk (CVaR) and Conditional Probability of Default (CPD) techniques are used to measure capital erosion. Significant increase in Probability of Default (PD) is found during the GFC period. The market asset value based approach indicates a much higher PD than external …

Thoughts On Var And Cvar, David E. Allen, Robert J. Powell
Research outputs pre 2011
Value at Risk (VaR) is an important issue for banks since its adoption as a primary risk metric in the Basel Accords and the requirement that it is calculated on a daily basis. VaR calculates maximum expected losses over a given time period at a given tolerance level. Conditional Value at Risk (CVaR) measures extreme risk. It calculates the risk beyond VaR. Relative industry risk measurement is also very important to Banks in their management of risk, such as for setting risk concentration limits and developing investment and credit policy. This paper examines market Value at Risk (VaR) and Conditional …
