Normal distribution of the residuals is the traditional assumption in the classicalmultivariate time series models. Nevertheless it is not very often consistent with the real data.Copulae allows for an extension of the classical time series models to nonelliptically distributedresiduals. In this...

Modeling the portfolio credit risk is one of the crucial issues of the last yearsin the financial problems. We propose the valuation model of Collateralized DebtObligations based on a one- and two-parameter copula and default intensities estimatedfrom market data. The presented method is used to...

Numerous papers have tried to understand housing's role in the economy and have not reached an agreement. In this paper we turn to the asymmetric relationship between housing and the overall economic activity. We find that the relation between building permits and GDP is regime-dependent....

With the recent availability of high-frequency nancial data the longrange dependence of volatility regained researchers' interest and has leadto the consideration of long memory models for realized volatility. Thelong range diagnosis of volatility, however, is usually stated for long...

In klassischen Wahlmodellen wird davon ausgegangen, dass sich ein beobachtetes Verhalten durch einen nicht näher spezifizierbaren Evaluationsprozess des beobachteten Individuums ergibt. Ist die Aufdeckung dieses Prozesses von Interesse, stoßen reine Wahlmodelle schnell an ihre methodischen...

This paper shows how to identify the structural shocks of a Vector Autoregression(VAR) while at the same time estimating a dynamic stochastic generalequilibrium (DSGE) model that is not assumed to replicate the data generatingprocess. It proposes a framework to estimate the parameters of the VAR...

Context effects can have a major influence on brand choice behavior after the introduction ofa new product. Based on behavioral literature, several hypotheses about the effects of a newbrand on perception, preferences and choice behavior can be derived, but studies with realchoice data are still...

Due to its ability to allow and account for similarities between pairs of alternatives, the nested logit model is increasingly used in practical applications. However the fact that there are two different specifications of the nested logit model has not received adequate attention. The utility...

Die Berechnung des VaR führt zur Reduktion der Dimension des Raumes der Risikofaktoren. Die vorzunehmenden Vereinfachungen resultieren aus unterschiedlichen Beweggründen, z.B. technische Effizienz, Sachlogik der Ergebnisse und statistische Adäquanz des Modells. Im Kapitel 2 stellen wir drei...
