Purpose – Switzerland boasts arguably the highest density of green properties in the world. In 2008, more than 15 percent of total new construction received the Swiss energy building label Minergie. The spatial distribution of these green buildings, however, is highly heterogeneous. In some...

We analyze the investment behavior of private clients concerning structured products. To ascertain their stated and revealed preferences, we use a questionnaire and a field experiment, respectively. The real product issued in the field experiment is comparable to one product in the questionnaire...

We examine the quantification of operational risk for banks. We adopt a financial-economics approach and interpret operational risk management as a means of optimizing the profitability of an institution along its value chain. We start by defining operational risk and then propose a...

We propose a simple and implementable model of credit contagion where we in-clude macro- and microstructural dependencies among the debtors within a creditportfolio. We show that, even for diversified portfolios, moderate microstructuraldependencies have already a significant impact on the tails...

The paper investigates how buyer-supplier firm-specific relationships affect security prices. Starting from the empirical inconsistencies associated with some standard structural models we propose a structural model of firm dependence in a vertically connected network of firms based on cash flow...

We present a multi-period mean-variance optimization program which allows for a joint optimization of the balance and off-balance sheet. Our first finding is the proof of a conjecture of Li and Ng (cf. [LN00]), Leippold, Trojani and Vanini (cf. [LTV04], [LTV03]) about the equivalence of the...

We propose a new continuous time framework to study asset prices under learning and ambiguity aversion. In a partial information Lucas economy with time additive power utility, a discount for ambiguity arises if and only if the elasticity of intertemporal substitution (EIS) is above one. Then,...
