Ostrom's analysis of Common Resource Pools can tie in to the curent 
discussion to the extent that CPR's emerge as unitended consequences 
of self interested behavior. I do not recall too much about the 
origin of CPR's in her book, it seems to focus more on their 
functions than on their origins. As I recall, the California water 
rights case study looked more at how this system originated, and it 
was not spontaneously. It would be interesting to see how other CPR 
systems, like Swiss grazing rights or Turkish fishing rights came 
into existence.
