As for "advanced technology" most of it is produced by cooperating scientists on public funding anyway :).

I don't know of case studies between cooperative and non cooperative enterprises relative performance.

There are a lot of discussions in the media about "finding the right model", French model, EU model, USA model, but none of these discussion seem to even mention cooperatives to the public attention.

Italy mentions coop in its constitution IIRC, Naomi Klein movie The Take shows workers taking back factories as coop in Argentina, Venezuela government is currently pushing to organize a massive coop movement.
