In Fight of the Century , Hayek sings:
The economy’s not a class you can master in college
To think otherwise is the pretense of knowledge
Here is Greg Mankiw in the New York Times :
AFTER more than a quarter-century as a professional economist, I have a confession to make: There is a lot I don’t know about the economy.
Greg is the founding member of the Pigou Club . I am happy to see that he has also joined the Hayek Club.
