The economic repercussions of a stock market crash depend less on the severity of the crash itself than on the response of economic policymakers, par… - Ben Bernanke

House prices have risen by nearly 25 percent over the past two years. Although speculative activity has increased in some areas, at a national level these price increases largely reflect strong economic fundamentals, including robust growth in jobs and incomes, low mortgage rates, steady rates of household formation, and factors that limit the expansion of housing supply in some areas.

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.
