In accordance with Basel Capital Accords, the Capital Requirements (CR) for market risk exposure of banks is a nonlinear function of Value-at-Risk (VaR). Importantly, the CR is calculated based on a bank’s actual portfolio, i.e. the portfolio represented by its current holdings. To tackle...

We document a negative and asymmetric contemporaneous relation of European stock and implied volatility returns. The negative relation is significantly more pronounced at the highest quantile of the stock market return distribution (i.e. largest price decrease). The relation between stock...

We examine time-varying behavior and determinants of asset swap (ASW) spreads for 23 iBoxx European corporate bond indexes stratified by industry, credit rating and seniority. The results of a Markov switching model suggest that ASW spreads exhibit regime dependent behavior. The evidence is...

We propose a novel method of Mean-Capital Requirement portfolio optimization. The optimization is performed using a parallel framework for optimization based on the Non-dominated Sorting Genetic Algorithm II. Capital requirements for market risk include an additional stress component introduced...

This study examines the operating performance of privatized firms in three Central European Transition Economies (CEE) between 1990 and 1998. Overall, we find no evidence of a significant improvement in operating performance for the first six years after privatization. Contrary to the increasing...

We analyse stock price behaviour around the disclosure of corporate insider transactions after the introduction of the Market Abuse Directive (MAD). Ranking according to our Insider Trading Enforcement (ITE) index highlights significant differences in the MAD enforcement between French and...

We use a 3-factor Regime Switching Threshold model to study common factors in the excess returns of 18 European corporate bond indices during 2000-2014. Our results document significant time variation of the common factors across bond indices for different maturities, ratings and industries. The...

We develop a novel approach to the bond portfolio optimization in insurance companies that are subject to the new Solvency II regulation. The regulatory efficient portfolios are determined using the Non-dominated Sorting Genetic Algorithm II (NSGA-II). The characteristics of the estimated...

We examine the impact of private equity (PE) directors and their human capital on operating performance in a unique hand collected sample of 200 secondary management buyouts (SMBOs) during 2000-2015. We show that PE directors' human capital tends to play statistically and economically important...
