We introduce a framework that analyzes the interplay of credit risk and collateral market risk on loan pricing. That for, we decompose any loan in unsecured and secured part. We further consider explicitly the recovery process. The framework allows us to develop semi-analytical pricing formulas...

Comparing realized dividends with dividend forecasts, we propose to describe dividend risk by a truncated t-distribution. We then investigate the impact of dividend uncertainty on European and American option prices. We find that the impact of dividend uncertainty on option prices is negligible...

We present a multi-period mean-variance optimization program which allows for a joint optimization of the balance and off-balance sheet. Our first finding is the proof of a conjecture of Li and Ng (2000), Leippold, Trojani and Vanini (2004, 2003) about the equivalence of the original...

We investigate how buyer-supplier firm-specific relationships affect security prices. We propose a structural model of firm dependence in a vertically connected network of firms based on cash flow transfers between buyers and suppliers. We prove that financial market completeness in a closed...

Economists have forcefully argued for the introduction and use of property derivatives as a hedge against house price risk (e.g. Shiller and Weiss, 1999). The rationale for these financial instruments seems clear, as many households are heavily invested in housing and standard financial...

We present a multi-period mean-variance optimization program which allows for a joint optimization of the balance and off-balance sheet. We first prove a conjecture of Li and Ng (2000), Leippold et al. (2004, 2003) about the equivalence of the original non-separable mean-variance problem and its...

One of the most enduring topics in financial theory is the persistence of investment risk across time. Traditional finance lacks methods for considering and hedging non-diversifiable risks. This paper is based on the general equilibrium model of Allen and Gale (1997). We extend their model in...

We show that for a production unit of a bank with well-defined workflows operational risk can be unambiguously defined and quantitatively modelled. The results of this modelling exercise are relevant for the implementation of a risk management framework: It turns out, that only a small share of...
