Clusters and knowledge flows are explored together with mobility within clusters followed by the
example of the Inkjet Printing Cluster in the Cambridge area. Labour mobility and knowledge spillovers in clusters are interrelated phenomena with knowledge embodied in entrepreneurs and specialised workers can spill over from one enterprise to another through labour mobility and direct revelation (Guarino and Tedeschi, 2006). It is found that knowledge diffused by the mobility of employees contributes to a cluster performing better through the generation of spinouts and the accumulation of knowledge (Dahl, 2002).
