Marc’s post reminds me that there was the EC-funded, STM-run PEER project that attempted to do exactly this comparison:
http://www.stm-assoc.org/public-affairs/resources/peer/ One of the aims of PEER was to discover the effect of Green OA on journal viability - for the journals that took part there were no negative effects on their viability.

I’m aware of two such studies, both made as part of the OAPEN initiative: one in the Netherlands and one in the UK (still ongoing, but preliminary results have been released). Interestingly, both found no measurable effect of toll-free availability on the sales. The only “effect” of toll-free access is a tremendous increase of use, as measured by summing the sales and the (much more numerous) downloads. Here also, fears that scholarly publishing is incompatible, or endangered by OA were, and still are, regularly aired. It’s possible that things are not the same for journal publishing. But, pending reliable results, we simply don’t know, and predictions as to a loss of subscriptions are nothing but speculation (or hypotheses).
