The plausible outcomes range from the gradual and benign to the more precipitous and damaging.

This crisis is not simply a more severe version of the usual business cycle recession, the typical downturn in which economies ultimately adjust and stabilize.

The world is likely to view any temporary extension of the income tax cuts for the top two percent as a prelude to a long-term or permanent extension, and that would hurt economic recovery as well by undermining confidence that we're prepared to make a commitment today to bring down our future deficits.

The choice is between which mistake is easier to correct: underdoing it or overdoing it.

Never before in modern times has so much of the world been simultaneously hit by a confluence of economic and financial turmoil such as we are now living through.

There is a basic lesson on financial crises that governments tend to wait too long, underestimate the risks, want to do too little. And it ultimately gets away from them, and they end up spending more money, causing much more damage to the economy.

Most consequential choices involve shades of gray, and some fog is often useful in getting things done

The rest of the world needs the U.S. economy and financial system to recover in order for it to revive. We remain at the center of global economic activity with financial and trade ties to every region of the globe.

Monetary policy itself cannot sensibly be directed at reducing imbalances.

Looking past the immediate crisis, a more resilient system must be built on stronger and better designed shock absorbers, both in the major institutions and in the infrastructure of the financial system.

We have parts of our system which are overwhelmed by regulation. It wasn't the absence of regulation that was the problem. It was despite the presence of regulation you got huge risks built up.

As financial markets continue to broaden and deepen, the behavior of asset prices will play an important role in the formulation of monetary policy going forward, perhaps a more important role than in the past.

The major economic policy challenges facing the nation today - pick your favorites among the usual suspects of low public and household savings, concerns about educational quality and achievement, high and rising income inequality, the large imbalances between our social insurance commitments and resources - are not about monetary policy.

In the financial system we have today, with less risk concentrated in banks, the probability of systemic financial crises may be lower than in traditional bank-centered financial systems

The government can help, but we need to make this transition now to a recovery led by private investment.

We believe in a strong dollar. Chinese financial assets are very safe.

I believe deeply that it's very important to the United States, to the economic health of the United States, that we maintain a strong dollar.

The recognition that things that are not sustainable will eventually come to an end does not give us much of a guide to whether the transition will be calm or exciting.
