In this paper we explore whether the incorporation of systematic time series analyses and mathematical optimization procedures in the practical planning process has the potential to improve production program decisions. The cases of four German cash crop farms are investigated over six planning...

Es wird ein liberaler Ansatz zum Umgang mit der aktuellen Corona-Pandemie vorgestellt, der mehr auf individuellen Entscheidungen und Eigenverantwortung setzt als auf staatliche Vorgaben und Zwang, die weder besonders effektiv noch effizient sind. Die Anwendung dieses Ansatzes wird für...

Multivariate Tobit models are estimated using German cross?sectional data to test whether strategic complementarities exist between expenditures in four different types of ICT?components. If two ICT?components are complements, they are correlated (provided that agents act rationally)....

The aim of this paper is to analyse the effects of knowledge management on the innovation success of firms in Germany. Using a matching procedure on data from the German Innovation Survey of 2003 (Mannheim Innovation Panel), we pair firms applying knowledge management with twin firms with...

Cartel detection is usually viewed as a key task of either competition authorities or compliance officials in firms with an elevated risk of cartelization. We argue that customers of hard core cartels can have both incentives and possibilities to detect such agreements on their own initiative...

In the German automobile industry the vertical integration, as an indicator of value added, is on average low. Beyond the argument of relative high labour costs for manufacturing, several specific reasons for the level of vertical integration, linked to the flexibility of business administration...

Nach dem Verbot der konventionellen Käfighaltung in Deutschland stellte sich die Frage nach der Wirtschaftlichkeit von artgerechten alternativen Haltungssystemen. Über die Kleingruppenhaltung, welche relativ neu ist und wieder zur Debatte steht, liegen kaum praxisnahe Informationen vor. Diese...
