A new RePEc service is now on-line, CollEc. The main goal of this initiative is to analyze co-authorship networks within Economics. To this end, it collects all the authorship data from the RePEc Author Service and computes the shortest path through co-authorship relationships between any two registered economists. From all this data, two “features” are computed.
First, a closeness and a betweenness score is computed for every economist. Closeness measure how close one is with everyone else. Betweenness measures how frequently shortest paths have a particular economist as a node. Of course, economists can be ranked according to both criteria.
Second, the website allows to display the shortest paths between any two economists, and one can be surprised at how short they often are. To play with this, either navigate the lists on CollEc or find the direct link to an author’s page on IDEAS (author profile, under “statistics”), then enter the name of another author.
Note that only authors registered with RePEc are considered. Also, not every registered author is part of this global network of co-authorship. For example, an author without a (registered) co-author is excluded. Also, an economist at the end of a path cannot have a betweenness score, mostly likely someone with a single (registered) co-author.
