A Ignorância dos Economistas

Do famoso professor de Harvard, Gregory Mankiw:

"(...) when Olivier Blanchard, the I.M.F.’s chief economist, was asked about the possibility of the world sinking into another Great Depression, he reassuringly replied that the chance was 'nearly nil.' He added, 'We’ve learned a few things in 80 years.'

(...)

Let me be clear: Like Mr. Blanchard at the I.M.F., I am not predicting another Great Depression. We have indeed learned a lot over the last 80 years. But you should take that economic forecast, like all others, with more than a single grain of salt."
