| Research Abstract |
In this study, I provided an empirical analysis of evolving networks of successful R&D collaboration in IT industry in the United States. Firstly, I analyzed the effect of existing network structure in the process of new R&D collaboration formation. I controlled for unobserved similarities among firms based on community structures with the network, and found a significant cyclic closure and preferential attachment effects. Secondly, I estimated the effect of patent inventors' collaboration networks on their productivity and mobility using U.S. patent application database. It is found that networked inventors are more productive and have longer tenure than non-networked inventors as the standard on-the-job-search model predicts. These results are consistent with the job search and match hypothesis between inventors and firms through collaboration networks.
