Here’s the PowerPoint presentation  that I used for my second lecture at the 2011 Cato University (held this year, btw, in one of my favorite towns: Annapolis, MD).
Because of several questions that I received after my first lecture, I began this second lecture with a brief review of the state of manufacturing in America. I used several of the great graphs that Mark Perry made available over the past few years at Carpe Diem . Of course, in my verbal remarks I explicitly acknowledged that these graphs are from Carpe Diem – and I encouraged the attendees to check out that indispensable blog.
Then I reviewed, first, Adam Smith’s explanation of the benefits of specialization, and, second, David Ricardo’s explanation (the principle of comparative advantage). I also combined Smith with Ricardo.
I concluded – after some too-quick remarks on various theories of the industrial revolution – by encouraging the attendees to read Deirdre McCloskey’s Bourgeois Dignity .
