In general, individuals will be interested in consumption of goods with “original”prices denominated in various currencies. Traditional risk management is nominally orientedand typically neglects this differentiated consumption preferences of investors. We outline therelevance of a consumption...

Investors need performance measures particularly as a means for funds selection inthe process of ex-ante portfolio optimization. Unfortunately, there are various performancemeasures recommended for different decision situations. Since an investor may be uncertainwhich kind of decision problem is...

Die Schätzung unbekannter Momente von Wertpapierrenditen ist unabdingbarfür praktische Anwendungen der Markowitz-Portfoliotheorie. Es wird gezeigt, wie dieses Datenbe-schaffungsproblem sowohl mittels mathematisch-statistischer Verfahren als auch durch die Nutzbar-machung des Expertenwissens...

The requirement of existing utility with positive first derivative only makes it pos-sible to derive a restricted two-fund separation theorem for portfolio selection problems withHARA utility replacing the original separation theorem of Cass and Stiglitz (1970). We useour findings for a brief...

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

Paradoxerweise kann sich die über das Jensen-Maß quantifizierte Performanceeines Investmentfonds verschlechtern, wenn der jeweilige Fondsmanager zusätzliche In-formationen erhält, auch wenn er diese im Interesse der Investoren zu nutzen gedenkt.Rechnerisch ist für dieses Phänomen eine...

In this paper the relation between aggregate mutual fund flows and stock market returns isanalysed with respect to three issues. First, we study the relation between fund flows andlong-term realized returns (past, current and future). Second, we find out that fund flows arenot driven by...

The requirement of positive marginal utility only makes it possible to derive a restricted twofundseparation theorem for portfolio selection problems replacing the original separation theorem ofCass 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 oneout 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...
