Most consequential choices involve shades of gray, and some fog is often useful in getting things done.
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.
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.
Although this crisis in some ways started in the United States, it is a global crisis. We bear a substantial share of the responsibility for what has happened, but factors that made the crisis so acute and so difficult to contain lie in a broader set of global forces that built up in the years before the start of our current troubles.
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.
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.
I personally believe that there's going to be a good case for the government preserving some type of guarantee to make sure that people have the ability to borrow to finance a house even in a very damaging recession. I think there's going to be a good case for that.
This crisis exposed very significant problems in the financial systems of the United States and some other major economies. Innovation got too far out in front of the knowledge of risk.

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.
But what we're determined to do, and what the reforms will do is to make sure this system goes back to its core purpose of taking the savings of Americans and from investors around the world and allocating those to people with an idea, not just the largest companies in the country, but to small businesses with an idea and a plan for growing.
Financial crises require governments.
The substantial uncertainty about the path of asset price movements going forward necessarily reduces the case for altering policy in advance of the move.
Some think that by preparing to deal with crises you make them more likely. I think the wiser judgment is the contrary. In this area at least, if you want peace or stability, it's better to prepare for war or instability.
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.
