"It was a global depression, had many causes, the whole story requires you to look at the whole international system. But policy errors in United States, as well as abroad, did play an important role. And in particular as I said, the Federal Reserve failed in this first challenge in both parts of its mission. It did not use monetary policy aggressively to prevent deflation and the collapse in the economy, so it failed in its economic stability function. And it didn't adequately perform its function as lender of last resort allowing many bank failures and a resulting contraction in credit and also with the money supply. So, in that respect, again, the Fed did not fulfill its intended mission."

“We did stop the meltdown. We avoided what would have been, I think, a collapse of the global financial system. That was obviously a good thing. But one thing that I was always sure of and the Federal Reserve was always sure of was that a collapse of some of these big financial firms was going to have very serious collateral consequences. There were people arguing even as late as September 2008, “Well, why don't you just let the firms collapse? There is a system that can take care of it: bankruptcy. Why don't you let them fail?” We never thought that was a good option. Particularly, if the whole system had collapsed, we would have had extraordinarily serious consequences.”

“Let me end my talk by abusing slightly my status as an official representative of the Federal Reserve System. 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.”

“Economics is a highly sophisticated field of thought that is superb at explaining to policymakers precisely why the choices they made in the past were wrong. About the future, not so much. However, careful economic analysis does have one important benefit, which is that it can help kill ideas that are completely logically inconsistent or wildly at variance with the data. This insight covers at least 90 percent of proposed economic policies.”

“There’s no denying that a collapse in stock prices today would pose serious macroeconomic challenges for the United States. Consumer spending would slow, and the U.S. economy would become less of a magnet for foreign investors. Economic growth, which in any case has recently been at unsustainable levels, would decline somewhat. History proves, however, that a smart central bank can protect the economy and the financial sector from the nastier side effects of a stock market collapse.”

“The economic repercussions of a stock market crash depend less on the severity of the crash itself than on the response of economic policymakers, particularly central bankers.”

“To avoid large and unsustainable budget deficits, the nation will ultimately have to choose among higher taxes, modifications to entitlement programs such as Social Security and Medicare, less spending on everything else from education to defense, or some combination of the above.”
