In the basic Markowitz and Merton models, a stock's weight in efficient portfolios goes up if its expected rate of return goes up. Put differently, there are no financial Giffen goods. By an example from mortgage choice we illustrate that for more complicated portfolio problems Giffen effects do...

Homebuyers in several countries may finance the purchase of their properties using different variants of either adjustable-rate mortgages (ARMs) or fixed-rate mortgages (FRMs). The variety and complexity of these loan products poses a risk management task for mortgage bank advisors to recommend...

In the basic mean/variance framework, a stock's weight in effcient portfolios goes up if its expected rate of return goes up. In more complicated, realistic portfolio choice problems, surprising effects can occur.

This paper argues that the relation between financial analysts' earnings forecast accuracy and their recommendation profitability has to be augmented by the extent of commonality in their forecast errors. We show that while accuracy is positively related to expected performance, the correlation...

We show the practical viability of a short-term treasury management model which is formulated as a multi-stage stochastic linear program. A company minimises the Conditional Value at Risk of final wealth, subject to given future cash flows and the uncertain future development of interest rates...

We consider optimal consumption and (strategic) asset allocation of an investor with uncertain lifetime. The problem is solved using a multi-stage stochastic linear programming (SLP) model to be able to generalize the closed-form solution obtained by Richard (1975). We account for aspects of the...
