I just posted this at Quora in response to a question about social innovation business models (note: I have edited a couple issues, but the posts are relatively the same–at the moment this document is more extensive & insightful):
1) Association Model: Collaborative Consumption (think Zip Car & Netflix)–but a similar model is used by mobile entrepreneurs who sell use of their phones. [similar to affordable co-working spaces for new businesses & group buying in principle]
2) Association Model: training, networking, events, etc. (Social Enterprise Alliance & the B-Corporation organization). Encourage best practices. (I don’t know how lucrative Co-ops are or can be, but they are relatively similar in nature–it seems that the association model is slightly better–but I’m sure its different on a case by case basis)
