Der Diskussionsbeitrag zeigt, wie der für die Unternehmensbewertung benötigte risikolose Basiszinssatz modellgestützt aus Kapitalmarktdaten gewonnen werden kann. Dies ist die Basis für eine konsistente Bewertung, die auf den unbestimmten Begriff des "landesüblichen Zinsfußes"...

Die Marktsegmentierung zählt neben der Neuproduktplanung und Preisgestaltung zu den wesentlichen Einsatzgebieten der Conjoint-Analyse. Neben traditionell eingesetzten zweistufigen Vorgehensweisen, bei denen Conjoint-Analyse und Segmentierung in zwei getrennten Schritten erfolgen, stehen heute...

For both deterministic or stochastic regressors, as well as parametric nonlinear or linear regression functions, we prove the weak consistency of the coefficient estimators for the Type I censored quantile regression model under different censoring mechanisms with censoring points depending on...

Dixit and Norman ("Theory of International Trade", Cambridge: Cambridge University Press, 1980) showed that, under certain conditions, the world economy replicates the equilibrium of the hypothetical integrated economy without national borders in the traditional trade model with perfect...

This paper proves three theorems on growth and competition in a standard increasing variety endogenous growth model and draws conclusions for second-best competition policies. First, no growth may be better than some growth, since modest positive growth potentially requires sizeable static...

A major topic in empirical finance is correlation of default risk. Correlations are the main drivers for credit risk on a portfolio basis and for banks� capital requirements under the New Basel Accord. However, empirical evidence on the magnitude of correlations is rather scarce, mainly due to...

Based on market basket data, multicategory purchase incidence models analyze demand interdependencies between product categories. We propose a finite mixture multivariate logit model to derive segment-specific intercategory effects of market basket purchase. Under the assumption that only a...

We estimate a New Keynesian DSGE model on French, German and Spanish data. The main aim of this paper is to check for the respective sets of parameters that are stable over time, making use of the ESS procedure ( ”Estimate of Set of Stable parameters“) developed by Inoue and Rossi (2011)....
