We propose a method to estimate the cost of debt in a continuous-time framework with an infinite time horizon. The approach builds on the class of well-known earnings before interest and taxes (EBIT)-based models. It extends other approaches based on option-pricing theory with a finite...

Providing a framework to integrate regret as an additional decision criterion in Markowitz's model of portfolio selection, we propose two different views on regret: An investor might feel regret with respect to the ex-post best alternative either in terms of return or in terms of preference...

We empirically assess the sensitivity of Basel risk weights to bank portfolio risk and the business cycle. With our econometric model, we distinguish between cross-sectional risk sensitivity and longitudinal risk sensitivity (cyclicality) of the regulatory standard. Employing a comprehensive...

We address the problem of minimizing the risk of an exposure (e.g., cash holdings) to a small number of defaultable counterparties based on spectral risk measures, in particular the expected shortfall. The resulting risk-minimal allocation turns out to be economically implausible in a number of...
