Biotechnology is considered as one of the key high-technology sectors in the future. It has been increasingly accepted that small, innovative businesses were the major stimulus for the development of this emerging industry. Many studies on new entrepreneurial entrants in biotechnology are mainly...

Because of the high degree of technological complexity and the increasing convergence of new technologies, it is becoming more and more difficult to develop advanced products for those companies who solely rely on their own in-house 'core competencies'. One possible response made to these rising...

Vor dem Hintergrund der hohen Bedeutung von Kooperationen in der Forschung und Entwicklung (FuE) in der Biotechnologie-Branche analysieren die Autoren mit einer empirischen Untersuchung relevante Einflussfaktoren auf die Effizienz von zwischenbetrieblichen FuE-Projekten. Basierend auf...

Vor dem Hintergrund der hohen Bedeutung von Forschungs- und Entwicklungskooperationen in der Biotechnologie analysieren die Autoren mit Hilfe einer empirischen Analyse die wesentlichen Einflussfaktoren auf das Management von zwischenbetrieblichen Entwicklungsprojekten. Basierend auf...

Unit root tests for time series with level shifts are considered. The level shift is assumed to occur at a known time point. In contrast to some other proposals the level shift is modeled as part of the intercept term of the stationary component of the data generation process which is separated...

The conditions under which European monetary policy is likely to be conducted are investigated by means of multi-variate time series modelling using aggregated data of all eleven European Monetary Union member states. A cointegration analysis identifies two stable long-run relationships within a...

It has long been recognized that aggregating time series introduces correlation between consecutive values of the aggregated observations (see Working (1960)). This paper investigates the effect of aggregation on the relation between variables assuming that the data generating process involves...
