Our paper investigates spillover effects across different business segments of publicly traded financial conglomerates. We find that the investment decisions of mutual fund shareholders do not just depend on the prior performance of the mutual funds, they also depend on the prior performance of...

We consider the problem faced by an investor who must liquidate a given basket of assets over a finite time horizon. The investor's goal is to maximize the expected utility of the sales revenues over a class of adaptive strategies. We assume that the investor's utility has constant absolute risk...

Liquidation of large portfolios in practice requires a longer time and smaller relative selling speed than the liquidation of small portfolios. Mean-variance optimal liquidation however results in the same relative selling speed and time horizon for small and large positions. We discuss three...

We consider the finite-time optimal portfolio liquidation problem for a von Neumann-Morgenstern investor with constant absolute risk aversion (CARA). As underlying market impact model, we use the continuous-time liquidity model of Almgren and Chriss (2000). We show that the expected utility of...

The main strategic objective of bank-affiliated venture capital funds (BVCs) is to enhance demand of debt capital from portfolio companies. This paper investigates the channels through which banks pursue such a strategy. Using detailed data from seven Western European countries in the period...

Firms can issue stocks classified in many ways. They can be classified in respect to voting rights, dividend rights, redemption rights, conversion rights, and many others. In this study, we ask if it is desirable to give greater freedom to firms in their choices of class shares. Making use of...

In this paper we stress-test credit portfolios of 28 German banks based on a Mertontype multi-factor credit risk model. The ad-hoc stress scenario is an economic downturn in the automobile industry that constitutes an exceptional but plausible event suggested by historical data. Rather than on a...

We extend the Hidden Markov Model for defaults of Crowder, Davis, and Giampieri (2005) to include covariates. The covariates enhance the prediction of transition probabilities from high to low default regimes. To estimate the model, we extend the EM estimating equations to account for the time...

In recent years new methods and models have been developed to quantify credit risk on a portfolio basis. CreditMetrics (tm), CreditRisk+, CreditPortfolio (tm) are among the best known and many others are similar to them. At first glance they are quite different in their approaches and...

Our paper addresses firm size as a driver of systematic credit risk in loans to small and medium enterprises (SMEs). Key contributions are the use of a unique data set of SME lending by over 400 German banks and relating systematic risk to the size dependence of regulatory capital requirements....
