Purpose The purpose of this paper is to provide a model that tests to what extent researchers’ interactions in the early stage of their collaborative network activities affect the number of collaborative outputs (COs) produced (e.g. joint publications, joint grant proposals and joint patents)....

Previous research shows that researchers’ social network metrics obtained from a collaborative output network (e.g., joint publications or co-authorship network) impact their performance determined by g-index. We use a richer dataset to show that a scholar's performance should be considered...

This paper presents a simple framework of the innovations that result from interfirm learning through exchanges of engineers in upstream-downstream relations within a production chain. To examine the framework, we empirically investigate the impact of mutual knowledge exchanges on product and...
