Der wachsende Wettbewerbsdruck im Bankensektor führte in den letzten Jahren trotz eines geringen Zinsniveaus zu sinkenden Zinsmargen im Verbraucherkreditgeschäft. Hervorgerufen wird diese Änderung der Angebotspreise durch die sinkende Bedeutung der Hausbankbeziehung sowie der steigenden...

The estimation of expected security returns is one of the major tasks for the practical implementation of the Markowitz portfolio optimization. Against this background, in 1992 Black and Litterman developed an approach based on (theoretically established) expected equili-brium returns which...

The measurement of concentration risk in credit portfolios is necessary for the determination of regulatory capital under Pillar 2 of Basel II as well as for managing portfolios and allocating economic capital. Existing multi-factor models that deal with concentration risk are often inconsistent...

The most relevant practical impediment to an application of the Markowitz portfolio selection approach is the problem of estimating return moments, in particular return expectations. We analyze the consequences of using return estimates implied by analysts' dividend forecasts under the explicit...

We are considering for examination an Irreversible Investment under Uncertainty, subsidized by the government. If the government announces the termination of a form of subsidization, investors may decide to realize their investment in order to obtain the subsidy. These investors might have...

Die Immobilienbewertung von Renditeobjekten erfolgt in Deutschland derzeit überwiegend über das so genannte Ertragswertverfahren, welches gesetzlich in der Wertermittlungsverordnung (WertV) verankert ist und mit dem Discounted-Cash-Flow (DCF) Verfahren aus dem angelsächsischen Raum...

We extend the continuous Cumulative Prospect Theory (CPT) by considering piecewise con-tinuous distributions with a finite number of jump discontinuities. Such distributions are rele-vant in practice, for example, within the framework of financial engineering since cash flow distributions of...

We conduct a general analysis of the effects of inequality aversion on decisions by homogeneous players in static and dynamic games. We distinguish between direct and indirect effects of inequality aversion. Direct effects are present when a player changes his action to affect disutility caused...

The parameter loss given default (LGD) of loans plays a crucial role for risk-based decision making of banks including risk-adjusted pricing. Depending on the quality of the estimation of LGDs, banks can gain significant competitive advantage. For bank loans, the estimation is usually based on...

This study examines the lead-lag-relationship between European equity and CDS markets in the context of the financial crisis. Previous research identified the stock market to lead the CDS market in an ordinary economic environment. Against the background of our study this lead-lag-relationship...
