Two weeks ago, the IMF organized a major research conference, in honor of Stanley Fischer, on lessons from the crisis. Here is my take. I shall focus on what I see as the lessons for monetary policy, but before I do this, let me mention two other important conclusions.
One, having your macro house in order pays off when there is an (external) crisis. In contrast to previous episodes, wise fiscal policy before this crisis gave emerging market countries the room to pursue countercyclical fiscal policies during the crisis, and this made a substantial difference.
Second, after a financial crisis, it is essential to rapidly clean up and recapitalize the banks. This did not happen in Japan in the 1990s, and was costly. But it did happen in the US in this crisis, and it helped the recovery.
Now let me now turn to monetary policy, and touch on three issues: the implications of the liquidity trap, the provision of liquidity, and the management of capital flows.
