Patri Friedman featured on Afternoons with Jim Mora on National Radio on Tuesday last week. The audio is available here, but I'm not sure for how many more days the link will work. I'd held off on blogging this one because Patri's interview aired about an hour before I sent out the take-home final exam for my public choice undergraduate class. The last question on that exam asked students to evaluate the prospects for Friedman's Seasteading as compared to Paul Romer's Charter Cities.
Unfortunately, Patri's audio feed isn't as good as it could have been. But still well worth a listen. Mora's done his background research and gives a friendly, albeit somewhat bemused, interview.
