This paper presents a multilevel model that examines the determinants of individual differences in ethical attitudes (as indicated in opinions of bribery) which underpin tax compliance (Alm & Torgler, 2011). The drivers of individual ethical attitudes are fundamental when examining individual...

While modern portfolio theory grounds on the trade-off between portfolio return and portfolio variance to determine the optimal investment decision, postmodern portfolio theory uses downside risk measures instead of the variance. Prominent examples are given by the risk measures Value-at-Risk...

Stress tests with handpicked scenarios might misrepresent risks either because dangerous scenarios are not considered or because the scenarios considered are too implausible. To overcome these two pitfalls we propose a systematic search for the worst case within a relative entropy ball of...

Studies such as Lemmon, Roberts and Zender (2008) demonstrate how stable firms’capital structures are over time, and raise the question of whether new theories of capital structure are needed to explain these phenomena. In this paper, I show that trade-off theory-based empirical proxies that...

This paper provides explicit expression for the lower bound and the upper bound of the overall VaR of a portfolio of business units when the joint risks factors of each business unit follows a mixture of multivariate elliptic distributions with dynamic conditional correlation matrix. We use...

For a given set of banks, which economic and financial scenarios will lead to big losses? How big can losses in such scenarios possibly get? These are the two central questions of macro stress tests. We believe that most current macro stress testing models have deficits in answering these...

We present a simple and operational yet rigorous framework that combines current methods of bank solvency stress tests with a description of fire sales. We demonstrate the applicability of our framework to the EBA stress testing exercise. Fire sales are described by an equilibrium model which...
