Debra Satz, Professor of Philosophy at Stanford University, talks with EconTalk host Russ Roberts about her book, Why Some Things Should Not Be For Sale: The Moral Limits of the Market. Satz argues that some markets are noxious and should not be allowed to operate freely. Topics discussed include organ sales, price spikes after natural disasters, the economic concept of efficiency and utilitarianism. The conversation includes a discussion of the possible limits of political intervention and whether it would be good to allow voters to sell their votes.
