We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them....

There is very little replication of research in economics, particularly compared with other sciences. This paper argues that there is a dire need for studies that replicate research, that their scarcity is due to poor or negative rewards for replicators, and that this could be improved with a...

RePEc is an open bibliography project driven entirely by volunteers and without a budget. It was created to enhance the dissemination of research in economics by making it more accessible to authors, publishers, and readers: 1800 publishers participate in this initiative, and 44000 authors are...

Are users of a bibliographic database interested in learning about replications? Can we motivate them to learn? To answer these questions, we performed an experiment on a RePEc (Research Papers in Economics) website: Using randomized stratification, we allocated 324 replications and their...

This paper studies the impact of collaboration on research output. First, we build a micro founded model for scientific knowledge production, where collaboration between researchers is represented by a bipartite network. The equilibrium of the game incorporates both the complementarity effect...
