BRINK LINDSEY, obviously no suckup, says that Joseph Stiglitz’s new book is very bad. This is a good argument for places like the Cato Institute, where Brink works. Stiglitz is a very famous economist, and dissing his book this way could be a damaging career move for an academic economist at many universities. At a think-tank, though, such considerations don’t exist in the same way. Think tanks, especially non-PC think tanks, thus help to promote intellectual diversity — which to me seems like a good thing.
