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...

Es wird dargelegt, dass das im Rahmen des Asset-Liability-Managements häufig gewählte Immunisierungsverfahren des Durationsmatch unter Verwendung der traditionellen Yieldbeta-Methode nur dann sachgerecht eingesetzt werden kann, wenn das betrachtete Unternehmen keinen sicheren realen und damit...

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...

Our main goal is the generalization of the approach of Jobson and Korkie(1984) for funds performance evaluation. Therefore, we consider the portfolio selection problem of an investor who faces short sales restrictions when choosing among F different investment funds and assume the investor's...

The requirement of positive marginal utility only makes it possible to derive a restricted twofund separation theorem for portfolio selection problems replacing the original separation theorem of Cass and Stiglitz (1970). We use our findings for a re-examination of the bias-in-beta problem in...

We consider investors with mean-variance-skewness preferences who aim at selecting one out of F different funds and combining it optimally with the riskless asset and direct stock holdings. Direct stock holdings are either exogenously or endogenously determined. In our theoretical section, we...

"Coherent" measures of a bank's whole risk capital imply a structure of a bank's optimal credit portfolio that is independent of its deposits and the expected deposit rate, of expected bankruptcy costs and of expected costs of regulatory capital. -- Basel II ; Regulatory Capital ; Coherent Risk...

We show analytically under quite general conditions that implied rates of return based on analysts' earnings forecasts are only a downward biased estimator for future expected one-period returns and therefore not suited for computing market risk premia. The extent of this bias is substantial as...

Two factors have proven to be strongly relevant for the subprime mortgage crisis. The first is the lack of screening incentives of originators, which had not been anticipated by investors. The second is that investors relied too much on credit ratings. We examine whether investors have learned...

In dem vorliegenden Beitrag wird erörtert, wie beschränkte Rationalität auf verschiedene Phasen der Gründungsfinanzierung einwirken kann. Dabei wird konkret die Venture Capital-Finanzierung als wohl bedeutendste Form einer Gründungsfinanzierung der Untersuchung zugrunde gelegt. Für diese...
