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...

Investors need performance measures particularly as a means for funds selection in the process of exante portfolio optimization. Unfortunately, there are various performance measures recommended for different decision situations. Since an investor may be uncertain which kind of decision problem...

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...

Several attempts have been made to reduce the impact of estimation errors on the optimal portfolio composition. On the one hand, improved estimators of the necessary moments have been developed and on the other hand, heuristic methods have been generated to enhance the portfolio performance, for...

Gemäß den bisherigen Vorschlägen des zweiten Konsultationspapiers des Baseler Ausschusses (Basel II) wird sich die Eigenkapitalunterlegung der Banken an der Bonität des jeweiligen Kreditnehmers orientieren. Es ist daher zu erwarten, dass damit auch die Festlegung der Kapitalkosten in...

Gemäß den im Juni dieses Jahres endgültig verabschiedeten Rahmenrichtlinien der neuen Baseler Kapitalstandards sind Kredite im Wesentlichen mit den unerwarteten Verlusten zu unterlegen. Für erwartete Verluste sind hingegen Rückstellungen zu bilden, wobei Differenzen zwi-schen erwarteten...

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...

According to the new capital adequacy framework (Basel II) finally adopted by the Basel Committee in June 2004 the eligibility of collaterals, especially financial collaterals, is extended in comparison to the existing rules. However, financial assets are valued conservatively in the credit...

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...

In this paper we develop an optimal dividend policy in the presence of limited rational inves-tors. Concretely, investors with mental accounts for dividends and stock prices as well as emotions like disappointment and elation embody the limited rationality. Furthermore, investors evaluate...
