It has been argued in the economic literature that job search through informal job networks improves the employer-employee match quality. This paper argues that inventors' research collaboration networks reduce the uncertainty of firms about the match qualities of inventors prior to hiring. We estimate the effect of inventors' collaboration networks on their productivity and mobility using the U.S. patent application database. It is found that networked inventors are more productive and have longer tenure than non-networked inventors. The evidence from fixed-effect regressions shows that the higher productivity and longer tenure of networked inventors are not solely attributable to unobserved ability of inventors or unobserved characteristics of firms. These results are consistent with the job match hypothesis between inventors and firms through their collaboration networks.
