Here’s a podcast with Robert Barro. We talk about growth, poverty, the US current account deficit and a few other things along the way. These EconTalk podcasts now have a "comments" section so feel free to discuss the Barro podcast there and any of the others.
At the end of the podcast is an economics riddle. Please use the "comments" section over there at EconTalk to try and answer it if you can. After a while, I’ll give my take on the problem.
This podcast with Barro is a little longer than the others—about 47 minutes. It would be very helpful to me to know if you like that length or prefer shorter ones in the 20-30 minute range. Just drop me a personal email and let me know.
