The monetary policy has been preferred to fiscal policy to fight the recession, at least for United States. While Quantitative Easing has been recurrently applied in many episodes, from QE1 to the more recent QE4, there has been less attention paid to the possible uses of fiscal policy.
There is a growing literature on what exactly the Quantitative Easing has achieved. As we are going see, there is an agreement that QE has led to both higher output and higher inflation, however, there is less agreement on the magnitude and persistence of these effects.
The Fed has recently announced that it will renounce to Quantitative Easing policy. Alan Blinder has a very interesting material that explains pretty well the rationales for why has the FED chosen this approach, how was implemented and what are the exit strategies.
