The most remarkable aspect of the recent conference at the IMF was the broad consensus that the macroeconomic models that had been relied upon in the past and had informed major aspects of monetary and macro-policy had failed. They failed to predict the crisis and they provided limited guidance on how the economy should respond. There was also remarkable consensus about many elements of policy in responding to the crisis, and there were even large areas of policy consensus for the longer run. In short, the conference made an important contribution in invigorating a balanced debate about reforming macroeconomics.
