Feldstein points out that other recent recessions were of short duration because the the Fed tightenend monetary policy to get back to price stability so that the Fed had some control over duration. This time the six years of steady house price increases has created a bubble which is the cause of this recession, and to make things worse it has affected the creditworthiness of institutions, as a cloud hangs over the assets carried by financial institutions because complex securities were created with risky mortgages and dispersed throughout assets of these financial institutions. So there is only so much the Fed can do. Feldstein is pessimistic about how long this recession could last. Feldstein faults the poor supervision and bank examinations of the Fed over banks and institutions they lend to such as nonbank financial institutions.
