This paper examines the relationship between Schumpeterian patterns of innovation and the generation of breakthrough inventions. Our data source for breakthrough inventions is the “R&D 100 awards” competition organized each year by the magazine Research & Development. Since 1963, this...

We study the patterns of engagement in collaborative research among university researchers. We investigate how frequently researchers engage in collaborative research with third parties, as well as the factors that affect the probability of interacting with industry as compared to other types of...

We use patent citation networks to study the dynamics of technical change in Ethernet, a standard for data communication. We first consider the evolution of the broad technological system of local area networks (LANs) and we identify the most significant inventions within the specific subfield...
