Ricardo’s difficult idea

Why intellectuals don’t understand comparative advantage
WithPaul Krugman

The title of this chapter is a play on that of an admirable recent book by the philosopher Daniel Dennett, Darwin’s Dangerous Idea: Evolution and the Meanings of Life (1995). Dennett’s book is an examination of the reasons why so many intellectuals remain hostile to the idea of evolution through natural selection-an idea that seems simple and compelling to those who understand it, but about which intelligent people somehow manage to get confused time and time again.
