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...

We present a geometric approach to discrete time multiperiod mean variance portfolio opti-mization that largely simplifies the mathematical analysis and the economic interpretation of such model settings. We show that multiperiod mean variance optimal policies can be decom-posed in an orthogonal...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value-added output, we calculate for each state the efficient frontier for investments in the real economy. We study how rapidly...

Starting from the Merton framework for firm defaults, we provide theanalytics and robustness of the relationship between defaultprobabilities and default correlations. We show that loans with higherdefault probabilities will not only have higher variances but also highercorrelations with other...

The current financial market crisis has impressively demonstrated the importance of aneffective credit risk management for financial institutions. At the same time, the use and thevaluation of credit derivatives has been widely criticised as a result of the crisis. Over the pastdecade, credit...

Entgegen früherer Studien, die darauf hinweisen, dass der gesamte Credit Spread eines Bonds durchdas mit diesem Bond verbundene Kreditrisiko induziert ist, zeigen neuere empirische Untersuchungen,dass neben Kreditrisiken noch weitere Faktoren die Höhe des Credit Spreads determinieren.Die...
