Economic cycles are the key credit portfolio risk driver and they are autocorrelated over time. We then show that it is economically meaningful to define risk for credit portfolios in a multi period setup. Since one period expected shortfall fails to measure risk adequately in a multi period...

Estimation of portfolio expected credit loss is required for IFRS9 regulatory purposes. It starts with the estimation of scenario loss at loan level, and then aggregated and summed up by scenario probability weights to obtain portfolio expected loss. This estimated loss can vary significantly,...

The capital asset pricing model (CAPM) receives both criticism and widespread adoption by practitioners and academics as the weighted average cost of capital (WACC) equity component. This study introduces two new costs of equity measures to address CAPM criticisms and provide new perspective on...

Using a panel of 504 Taiwanese listed firms during a 10-year period (2002-2011), this study tests whether there is an optimal level of board ownership, which maximizes firm value. This work adopts Tobin’s Q as the proxy for firm value and finds that board ownership between 11.57% and 14.35%...

Over the last two decades, a number of financial disasters have occurred due to failure in risk management procedures. If some, as the Asian financial crisis, had a very much more muted global impact (even though they sent shock waves through global financial markets, the main damage were fairly...

Previous empirical work suggests that, when using corporate bond indices, the yield spread sensitivity of corporate bonds to changes in the yield curve is negative and significant, especially for the A and BBB-rated bond categories. We use a sample of 5500 US corporate bonds to construct bond...

This article presents a generic model for pricing financial derivatives subject to counterparty credit risk. Both unilateral and bilateral types of credit risks are considered. Our study shows that credit risk should be modeled as American style options in most cases, which require a backward...

Pushing models to extremes can expose output biases that stem from underlying assumptions. In the case of industry standard option valuation models, long term, high volatility securities provide a stress test vehicle. For instance, in evaluating a stock with 60% volatility, industry standard...
