If You Can Do It For Free, There Is Some Way to Do It For Money

Markets without Limits defends the claim that there are no inherent limits to markets, in the sense that if something may permissibly be given away or exchanged outside of market or for free, then there is some realistic and plausible way of structuring a market that makes it morally permissible to exchange it for money. This paper reviews the basic strategy of the book, and then responds to criticisms from Geoffrey Hodgson’s recent review. Hodgson claims to have identified counterexamples to our main thesis, which we dispute.
