‘MNC strategies to limit knowledge spillovers: How subsidiaries manage their knowledge source breadth to decrease spillovers’


The aim of this paper is to investigate the factors influencing the speed at which knowledge flows from foreign to domestic firms. The focus is not on whether a knowledge spillover occurs, but on the time an MNC subsidiary’s knowledge takes to spread in the surroundings. We propose a conceptual model where the speed of local knowledge diffusion is influenced by the technology sourcing strategies of subsidiaries. We then test our model using a database covering 1394 US patents from foreign MNC subsidiaries in the semiconductors sector. We find that not only the breadth of the set of subsidiary knowledge sources does slow down local knowledge diffusion, but that the delay is mainly related to the diversity of global and internal sources used by the subsidiary, hinting at strategies that MNCs can use to further protect their knowledge.


Francesco Rullani is Assistant Professor at LUISS Guido Carli in Rome (IT) and Visiting Associate Professor at Copenhagen Business School. Previously, he has been Assistant Professor at Copenhagen Business School, visiting fellow at Stanford University and Bocconi University. He received his Ph.D. from Sant’Anna School of Advanced Studies. His research focuses on knowledge production and sharing in self-organized settings such as open source software. He has also recently broaden his research interests including other settings in which knowledge is diffused, more or less formally and intentionally, and where innovation is used to generate inclusion of marginalized individuals (e.g., social enterprises). Francesco has explored these themes employing mainly quantitative techniques applied to large databases, but also theoretical elaboration and formal modeling. His research has been published in journals such as Strategic Management Journal, Research Policy, Industrial and Corporate Change, International Journal of Industrial Organization and Industry and Innovation.
