I simply do not understand most of the thinking that goes on here at the Fed and I do not understand how this thinking can go on when in my view it smacks up against reality.
Please allow me to begin with methodology, I hold the view developed by such great economic thinkers as Ludwig von Mises, Friedrich Hayek and Murray Rothbard that there are no constants in the science of economics similar to those in the physical sciences.
In the science of physics, we know that water freezes at 32 degrees. We can predict with immense accuracy exactly how far a rocket ship will travel filled with 500 gallons of fuel. There is preciseness because there are constants, which do not change and upon which equations can be constructed..
There are no such constants in the field of economics since the science of economics deals with human action, which can change at any time. If potato prices remain the same for 10 weeks, it does not mean they will be the same the following day. I defy anyone in this room to provide me with a constant in the field of economics that has the same unchanging constancy that exists in the fields of physics or chemistry.
And yet, in paper after paper here at the Federal Reserve, I see equations built as though constants do exist. It is as if one were to assume a constant relationship existed between interest rates here and in Russia and throughout the world, and create equations based on this belief and then attempt to trade based on these equations. That was tried and the result was the blow up of the fund Long Term Capital Management, a blow up that resulted in high level meetings in this very building.
