This week's episode with David Autor did not go as I planned. I thought we would spend most of the time on the empirical estimates he and his co-authors have made of the impact of US trade with China. Eventually, we got to those estimates along with how reliable they are and the possible implications for public policy. But along we way, we had a lengthy discussion of the fundamentals of trade, trade deficits, and the complexity of labor markets. Because this was such a lively conversation and because it is such a timely issue, I invited four blogging economists--Don Boudreaux, Arnold Kling, Adam Ozimek, and Noah Smith to respond to the conversation. You'll find their reactions below the fold. And you have a chance to respond to those reactions in the comment section.
