It will come as no surprise to those who know me that I did not argue in favor of additional monetary accommodation during our meetings last week. I have repeatedly made it clear, in internal FOMC deliberations and in public speeches, that I believe that with each program we undertake to venture further in that direction, we are sailing deeper into uncharted waters. We are blessed at the Fed with sophisticated econometric models and superb analysts. We can easily conjure up plausible theories as to what we will do when it comes to our next tack or eventually reversing course. The truth, however, is that nobody on the committee, nor on our staffs at the Board of Governors and the 12 Banks, really knows what is holding back the economy. Nobody really knows what will work to get the economy back on course. And nobody—in fact, no central bank anywhere on the planet—has the experience of successfully navigating a return home from the place in which we now find ourselves. No central bank—not, at least, the Federal Reserve—has ever been on this cruise before.
