Interpreting The Unconventional U.S. Monetary Policy Of 2007-09
This paper reviews the unconventional U.S. monetary policy responses to the financial and real crises of 2007-09, divided into three groups: interest rate policy, quantitative policy, and credit policy. To interpret interest rate policy, it compares the Federal Reserve's actions with the literature on optimal policy in a liquidity trap. This comparison suggests that policy has been in the direction indicated by theory, but it has not gone far enough. To interpret quantitative policy, the paper reviews the determination of inflation under different policy regimes.
