Although building operating charges have turned out to be a major determinant of profitability for real estate investments, there is a noticeable lack of reports or studies that analyze these costs with state-of-the-art statistical techniques. Specifically, past studies usually assume linear...

The most widely used approaches in hedonic price modelling of real estate data and price index construction are Time Dummy and Imputation methods. Both methods, however, reveal extreme approaches regarding regression modeling of real estate data. In the time dummy approach, the data are pooled...

We apply additive mixed regression models (AMM) to estimate hedonic price equations. Non-linear effects of continuous covariates as well as a smooth time trend are modeled non-parametrically through P-splines. Unobserved district-specific heterogeneity is modeled in two ways: First, by location...

This paper analyzes house price data belonging to three hierarchical levels of spatial units. House selling prices with associated individual attributes (the elementary level-1) are grouped within municipalities (level-2), which form districts (level-3), which are themselves nested in counties...

Modeling spatial heterogeneity (SH) is a controversial subject in real estate economics. Single-family-home prices in Austria are explored to investigate the capability of global and locally weighted hedonic models. Even if regional indicators are not fully capable to model SH and technical...

The vocational training system is an important factor within the German institutionalframework. Its high output of skilled and well-educated employees provides a basis for Germany's export success and innovation. In the last few years, however,growing concern has been expressed about the...

Ein klarer Fachkräftemangel behindert das Wachstum der Informationstechnik (IT)-Branche nicht nur in Deutschland, sondern auch in anderen Ländern. In dieser Studie wird untersucht, in welchem Ausmaß Schulabgänger mit einem Studium der Informatik in fünf industrialisierten Ländern, den USA,...

Obwohl gegenwärtig viele Autoren das "Produktivitätsparadox der Informationstechnik" als ein Thema ansehen, das, zumindest in den USA, auf der Firmenebene gelöst wurde, bleiben noch einige Unklarheiten auf den Ebenen von Branchen- und Volkswirtschaft bestehen. Der vorliegende Beitrag...
