Giro alla lista perche' di interesse: effetti dell'OA sulle citazioni
- aumento di competitivita'
- aumento di citazioni solo per i lavori di qualita'
almeno cosi' pare dall'abstract
Merita lettura approfondita

Hi Folks:

Chris Snyder and I have just completed our first empirical analysis of
Open Access, as opposed to online access in general (using data from 100
Science Journals).  The results are new to this literature, and should
generate a fair amount of discussion regarding their
implications (which we have not yet begun to formally assess).  We would
appreciate your feedback too.  :-)

Regards, Mark McCabe

The Rich Get Richer and the Poor Get Poorer:  The Effect of Open
Access on Cites to Science Journals Across the Quality Spectrum


An open-access journal allows free online access to its articles,
obtaining revenue from fees charged to submitting authors. Using panel
data on science journals, we are able to circumvent some problems
plaguing previous studies of the impact of open access on citations. We
find that moving from paid to open access increases cites by 8% on average
in our sample, but the effect varies across the quality of content. Open
access increases cites to the best content (top-ranked journals or
articles in upper quintiles of citations within a volume) but reduces
cites to lower-quality content. We construct a model to explain these
findings in which being placed on a broad open-access platform can
increase the competition among articles for readers’
attention. We can find structural parameters allowing the model to fit the
quintile results quite closely.
