"Economics is a difficult subject, because we cannot conduct controlled experiments. There are not two or three Argentina's, one following the experiment that I described above, and another adopting the policies that I prefer. But we do have a wealth of experience from which to draw inferences. This wealth of experience all points in one direction: Keynes's teachings are still very much alive, and Argentina today would be in far better shape if his lessons had been taken to heart."

"Die Ökonomie ist die einzige Wissenschaft, in der sich zwei Menschen einen Nobelpreis teilen können, weil ihre Theorien sich gegenseitig widerlegen."
