Markets Without Limits with Jason Brennan & Peter Jaworski
Jason Brennan and Peter Jaworski join Kim Krawiec, student co-hosts Joe Keys and Jake Ross, and members of UVA Law’s Taboo Trades seminar to discuss the second edition of Markets without Limits: Moral Virtues and Commercial Interests , a foundational work in the debate over the moral limits of markets. Their central claim is provocative: if you may do something for free and whether to do it is within your discretion, there is some way you may do it for money. The argument leaves room for moral duties and extensive regulation while challenging critics to explain what payment itself makes wrong. The conversation explores the burden of proof in arguments against markets, the famous Israeli daycare-fine study, and whether money corrupts our motives or changes what we learn about a situation. Examples ranging from dog breeding and education to organ markets and lifesaving rescues raise difficult questions about inequality, discretion, and the gap between moral permission and workable legal rules.
