Bei der Effizienzanalyse von Banken haben sich die Arbeiten bislang die Standortfaktoren vollständig vernachlässigt. In der Arbeit soll der Einfluß der Standortfaktoren einer Bank auf das Effizienzniveau untersucht werden, indem eine Integration der Faktoren in ein DEA Modell unternommen...

Für die Darstellung des Produktionsprozesses einer Bank gibt es unterschiedliche Möglichkeiten. Bisher besteht in der Literatur kein Wissen darüber, in wie weit die unterschiedlichen Ansätze zu übereinstimmenden Ergebnisse in der Effizienzanalyse kommen. In der Arbeit werden mit dem...

The problem of optimal decision among unit roots, trend stationarity, and trend stationarity with structural breaks is considered. Each class is represented by a hierarchically random process whose parameters are distributed in a non-informative way. The prior frequency for all three processes...

This paper analyzes the higher-order properties of nested pseudo-likelihood (NPL) estimators and their practical implementation for parametric discrete Markov decision models in which the probability distribution is defined as a fixed point. We propose a new NPL estimator that can achieve...

Journals favor rejection of the null hypothesis. This selection upon tests may distort the behavior of researchers. Using 50,000 tests published between 2005 and 2011 in the AER, JPE, and QJE, we identify a residual in the distribution of tests that cannot be explained by selection. The...

The occurrence of decision problems with changing roles of null and alternative hypotheses has increased interest in extending the classical hypothesis testing setup. Particularly, confirmation analysis has been in the focus of some recent contributions in econometrics. We emphasize that...

This paper presents an application of a multi-attribute aggregation methodology to the construction of a sustainability index. Sustainability is a multi-faceted issue, in which synergies or conflicts may arise among the different components, thus making it a complex concept to which multi...

In projects with a flexible project structure, the activities that have to be scheduled are not completely known beforehand. Instead, scheduling such a project includes the decision whether to carry out particular activities at all. This also effects precedence constraints between the finally...

We study single period asset allocation problems of the investor who maximizes the expected utility with respect to non-additive beliefs. The non-additive beliefs of the investor model the presence of an uncertainty and they are assumed to be consistent with the Maxmin expected utility theory of...
