Diffusionsprozesse bei zwischenbetrieblicher Kooperation - Ein erweitertes Nelson-Winter-Modell

The simulation studies presented by Nelsen and Winter (1982) examine the modelling of industry dynamics. These studies are a prominent and unique approach visualizing innovation and imitation processes. Assuming the standard model envisages firms acting individually, this paper treats the question concerning how the dynamic of the market changes in the case of inter-firm cooperation. Thereby we refer to one of our case studies (Brunner / Voigt 2008) and reconstruct interactions between the cooperation participants. On the one hand, we extend the Nelson-Winter-model by a factor market where the cooperation is able to bundle its demand. On the other hand, the model is enlarged by interactions of the cooperation actors in terms of innovation and imitation processes. A fundamental result of the simulation studies is that the cooperation participants improve their market position due to the cooperation. In particular, this study shows how the cooperation supports and simultaneously accelerates the dissemination of innovation.
