How can the pros and cons of collaboration networks among companies be explained by appropriate quantitative models? Mark Wipprich begins this work by making suggestions for an adequate division of work in collaboration networks. Against this backdrop, he develops appropriate models. He then analyzes the emerging network structures in the case of the decentralized or centralized coordination of companies, and focuses on the stability of emerging networks in both cases. Following this, the author verifies the application and the flexibility of the model in respect to real situations. In conclusion, he integrates competition into the quantitative modelling of collaboration networks among firms, and shows that firms can influence their competitive position by forming networks and in doing so can influence the market structure and the profits.
