O ERRO DE MILTON FRIEDMAN


It’s one of Ben Bernanke’s most memorable quotes: at a conference honoring Milton Friedman on his 90th birthday, he
said:

"Let me end my talk by abusing slightly my status as an official representative of the Federal Reserve. I would like to say to Milton and Anna: Regarding the Great Depression. You’re right, we did it. We’re very sorry. But thanks to you, we won’t do it again."

He was referring to the Friedman-Schwartz argument that the Fed could have prevented the Great Depression if only it has been more aggressive in countering the fall in the money supply. This argument later mutated into the claim that the Fed caused the Depression, but its original version still packed a strong punch. Basically, it implied that no fundamental reforms of the economy were necessary; all it takes to avoid depressions is for central banks to do their job.
But can we say that recent events appear to disprove that claim? (So did Japan’s experience in the 1990s, but that lesson failed to sink in.) What we have now is a Fed that is determined not to “do it again.” It has been very aggressive about monetary expansion. Here’s one measure of that aggressiveness, banks’ excess reserves:

And yet the world economy is still falling off a cliff.
Preventing depressions, it turns out, is a lot harder than we were taught.
