This is the legacy version of CollEc. The more
recent version is 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 46788 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.

Note that the data on this site go back to the RAS data of
2021‒02‒01. Over the rest of the year, we will calculate the
rankings and full paths. At this time, we expect the
calculations to be complete in August. On 2022‒01‒01, we will
take a new copy of RAS data and start to calculate again.

Our data is available via the RePEc rsync site.

There is some documentation.
