Enjoyed the podcast; as always, a stimulating discussion. Russ is at his best when he doesn’t fully agree with a guest, yet finds ways to allow both his and the guest’s point to come across. That happened a number of times during this podcast, such as during the Pigou Club debate. The back and forth between Dr. Mankiw and Russ made for great listening. I hope Russ tries to get Krugman, Galbraith or Stiglitz for future podcasts.

I was a bit disappointed about the approach on externalities, particularly with the somewhat detached perspective of both Russ and Dr. Mankiw. Assuming that there is a scientific controversy over this, or suggesting, albeit somewhat glibly, that for some people air conditioners may be the answer for global warming, was disheartening.

There is no scientific controversy. Climate change is the most important externality of our generation, and of others to follow. It is important that academic economists, particularly those with stature and share of voice, as both Russ and Dr. Mankiw have, take a more nuanced view on this.

I enjoy your econtalk podcasts and this interview of Mankiw was no exception. I have two comments. One, I was surprised at your view that moderating entitlements would become easier as we become wealthier. I wish you were right, but if anything the evidence of history goes the other way. We are far wealthier now than we were in the 50’s, or any other earlier time, but it seems to me the sense of entitlement has done nothing but grow stronger and more encompassing. In fact, entitlements seem to be self-feeding. How developed was the sense of entitlement in, say, the 19th century?

Second comment, is while the discussion and exchanges with Mankiw was stimulating, I wish you had asked him a bit about his experience as chairman of the COEA. After all, that’s an experience only a small number of economists have had. Or maybe that was a topic he wanted to stay away from, for now?

Saeed and Enronal,

Thanks for you comments. My point about global warming (and many other issues) is that our ability to deal with these challenges in a decentralized, voluntary way increases as we get wealthier. In the 1500’s, the ability of individuals to deal with climate was very limited–the only real option was migration to a more pleasant climate. Today, we have many more choices because of the technology we haveavailable. Didn’t mean to be detached or glib about air-conditioning–I meant it as an example of a general principle. I hope to write something more extensive on this topic in the next few months at econlib.org

It was my choice to stay away from Greg’s White House experience. You can find the transcript of an interview I did with him (pre-podcast) in the links related to the podcast–“Interview with Greg Mankiw,” where we talk more about his work in the White House.
