Siccome ce ne siamo occupati in un recente articolo (L'accesso e la
distribuzione dei saperi scientifici -
http://newbrainframes.org/journal/art.php?id=730) credo che possa
interessare questo paper.

Using a database of all published articles in economic journals over
the last 30 years, we investigate the determinants of scientific
co-authorship. We find that, controlling for pair-wise fixed effects
and author productivity, a new collaboration emerges faster if the two
authors are more closely connected, either directly or indirectly,
through collaborations with others.
This effect is strong and robust. It is consistent with a referral
model of the formation of scientific collaborations. We also find that
large differences in research output between authors favor
co-authorship, suggesting that scientific collaboration is more likely
between authors with dissimilar ability and experience. This effect
disappears if we limit the data to highly productive authors.
