摘要
We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can maximize it. Through the links in thecollaboration network, researchers create spillovers not only to their direct coauthorsbut also to researchers indirectly linked to them. We characterize the equilibriumwhen agents collaborate in multiple and possibly overlapping projects. We bring ourmodel to the data by analyzing the coauthorship network of economists registered inthe RePEc Author Service. We rank the authors and research institutions according totheir contribution to the aggregate research output and thus provide a novel rankingmeasure that explicitly takes into account the spillover effect generated in the coauthorship network. Moreover, we analyze funding instruments for individual researchers as well as research institutions and compare them with the economics funding program of the National Science Foundation. Our results indicate that, because current funding schemes do not take into account the availability of coauthorship network data, they are ill-designed to take advantage of the spillover effects generated in scientific knowledge production networks.
