Christina Romer, economic advisor to President Obama, offers a different view about monetary policy in 2011, suggesting that monetary easing after QE II should continue. She also argues for higher stimulus. She cites the improved economy in the period 1933-1937 as an example of the advantages of monetary easing, of 1937-1940 as a period where a focus on deficits resulted in a fall back of the U.S. economy. This is a view presented also by Paul Krugman. Meltzer's and Fed Governor Hoenig's view is that excessive monetary easing in 2003 created bubbles and that QE II has not reduced unemployment. Meltzer warned in 2009 that excessive monetary easing needed to be gradually withdrawn rather than risk an excesssive contraction later on.
