If, being conservative, I estimate that 33% of all desired article
access do not
occur due to access problems then:

Kurtz, et al, JASIST 56, 36 (2004)
discussed the value of the interlinked system of electronic journals and
indices in astronomy
(which approximate a fully interlinked, local OA system) and found that
it amounts to an
efficiency increase in 6% in total research output.

A one third reduction of this benefit, due to closed access, would be 2%
of total research.
If the total R&D budget of the world is a tera-dollar then 2% is $20
billion. For comparison
the entire direct cost of publishing is normally estimated at a little
less than 1%, or $10 billion.

This says that the value of OA is twice the cost of the STM publishing

This does not include any benefit which would come from articles being
read by the public.
