Here there is a relatively short distance--many of the questions that you will be dealing with in the next two days are those that my colleagues in the ECB, the banks of Australia, Canada, England, Japan, and on down the list, and the Fed deal with.
Policymakers probably do not deal with these questions in the same way as researchers--I have seen very few propositions proved in my five years of going to Federal Open Market Committee (FOMC) meetings. But we deal with them in our own ways and they are the same questions.
