After "The Wealth of Networks" the question if peer production is desirable and viable is answered. What remains is how to mix it with the market economy. If peer production is going to play that revolutionary role that Yochai Benkler predicts it will this shall be a crucial question for all kinds of businesses. And it is not trivial - as psychology shows (see for example: "Effort for Payment - a tale of two markets") monetary reward crowds out other incentives. We need to divide the work very carefully so that the market part does not destroy the peer production. And to make this precise division we need to know more about the psychological mechanism of incentives crowding out and also about the economic feasibility of provisioning a particular work by peer production. Even a nonprofit organisation needs pay some bills - and what are for profit business models compatible with peer production? Some first answers were worked out by the Open Source and Free Software movements (for example
Open Source Case for Business), but I have not found any more systematic treatment of that subject - a framework guiding us when evaluating not yet discovered business models.
