CollEc

CollEc provides rankings by co-authorship centrality for authors registered in the RePEc Author Service, as maintained by Christian Zimmermann.

We have centrality rankings.

Closeness ranking looks at how far an author is, on average, to all others economists.
Betweenness ranking looks how many times an author appears on average on shortest paths between all other economists.

You can use the authors linked to by the rankings to find paths to any of the economists in the network. If you are in the network use a RAS handle to find yourself, and from you, find the path to anybody else in the network by name searches.

Our data is available via the RePEc rsync site.

There is some documentation.
