In our recent publication in the Journal of Evolutionary Economics, Maureen McKelvey (University of Gothenburg), Pablo D’Este (INGENIO), and myself study which mechanisms drive the formation of new collaborative relations to knowledge translators – i.e., investigators that have basic and clinical research knowledge – in clinical trials. Our results indicate that the network of clinical trial investigators remains fragmented over time. This fragmentation is problematic as it limits opportunities for knowledge transfer which may negatively influence knowledge generation and innovation based on clinical research. With respect to the mechanisms that drive tie formation, we find that similarity in terms of research fields and investigators’ country of affiliation and dissimilarity in terms of publication output promote the formation of ties to knowledge translators. Our study can be found here.
