East German wages have been below the West German wage level since unification. Moreover, the East-West wage gap implied by the contractual wagesspecified in collective wage agreements is drifting ever further apart from the wagegap in terms of effective wages. This paper looks at the role of...

In this paper we introduce the dynamic semiparametric factor model (DSFM) for electricity forward curves. The biggest advantage of our approach is that it not only leads to smooth,seasonal forward curves extracted from exchange traded futures and forward electricity contracts, but also to a...

Comparing groups with respect to hypothetical constructs requires that the measurement models are equal across groups. Otherwise conclusions drawn from the observed indicators regarding differences at the latent level (mean differences, differences in the structural relations) might be severly...

E-learning plays an important role in education as it supports online education viacomputer networks and provides educational services by utilising information technologies. We present a case study describing the development of an Arabic language elearning course in statistics. Discussed are...

Integrated choice and latent variable (ICLV) models represent a promising newclass of models which merge classic choice models with the structural equation approach (SEM) for latent variables. Despite their conceptual appeal, to date applications of ICLV models in marketing are still rare. The...

High-dimensional regression problems which reveal dynamic behavior are typicallyanalyzed by time propagation of a few number of factors. The inference on thewhole system is then based on the low-dimensional time series analysis. Such highdimensional problems occur frequently in many different...

After years of stagnancy, PLS path modeling has recently attracted renewed interest from applied researchers in marketing. At the same time, the availability of software alternatives to Lohmöllers LVPLS package has considerably increased (PLS-Graph, PLS-GUI, SPAD-PLS, SmartPLS). To help the...

Many researchers seem to be unsure about how to specify formative measurement models in software programs like LISREL or AMOS and to establish identification of the corresponding structural equation model. In order to make identification easier, a new, mainly graphicallyoriented approach is...

Dieser Beitrag setzt sich mit der Leistungsfähigkeit von Strukturgleichungsmodellen bei derValiditätsprüfung von Messmodellen für hypothetische Konstrukte auseinander und geht aufausgewählte Problembereiche bei der gängigen Anwendung dieser Methodik für dieSkalenkonstruktion ein....
