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...

Credit ratings are ordinal predictions for the default risk of an obligor. To evaluate the accuracy of such predictions commonly used measures are the Accuracy Ratio or, equivalently, the Area under the ROC curve. The disadvantage of these measures is that they treat default as a binary variable...

In credit default prediction models, the need to deal with time-varying covariates often arises. For instance, in the context of corporate default prediction a typical approach is to estimate a hazard model by regressing the hazard rate on time-varying covariates like balance sheet or stock...

We consider the provision of venture capital in a dynamic agency model. In particular, we focus on the interaction between venture capital financing and product market competition: A young firm with a risky innovation project attempts to enter a market where it faces two periods of price...

This paper shows that obligations from debt hinder tacit collusion if equity owners are protected by limited liability. In contrast to its advantageous commitment value in short-run competition, leverage reduces profits from infinite interaction. Contrasting uncorrelated shocks with a cyclical...

This study examines how family firm characteristics affect capital structure decisions. In our analysis we disentangle the influence of three distinct components of a family firm: ownership, supervisory and management board activities by the founding family. Thereby, we use a unique panel...

The paper analyzes internal factors which influence the use of equity - and mezzanine-based financing instruments in German privately held family firms. Based on a sample of 195 surveys of family firms, we investigate the impact of family specific goals and corporate governance structures on the...

While in the US stock-based incentives are commonly used since the 50s of the last century, in Germany they were invented only some ten years ago. Even in 1996 firms faced considerable regulatory difficulties when willing to grant such incentives. In the meantime the legal environment has...

We analyse to what extent the accrual anomaly is related to the choice of the accounting system as well as firm-level heterogeneity in corporate governance mechanisms. Using a unique dataset of listed German firms over the period 1995 to 2005 we first corroborate former results indicating that...

Around the world (with the U.S. and U.K. as exceptions) concentrated ownership structures and controlling shareholders are predominant even among listed firms. We provide novel empirical evidence how such controlling shareholders, in particular founding families, affect payout policy decisions....
