Michael Woodford Endorses Nominal GDP Level Targeting

% of readers think this story is Fact. Add your two cents.

Michael Woodford, arguably the top monetary economist in the world, endorsed nominal GDP level targeting today at the Jackson Hole Economic Symposium.  He did so as part of a broader critique of the Fed’s monetary policy over the past four years.  Among other things, he makes the following points in his critique:

(1)  Quantitative Easing has not been very effective because the increase in monetary base it created is not expected to be permanent.  If it were expected to permanent, then the future price level and nominal income level would also be expected to permanently increase.  Households and firms would respond to this development by increasing nominal spending today. The key point is to communicate some part of the monetary base increase will be permanent. See Bill Woolsey for more on this issue. 

(2)  The forward guidance provided by the Fed on the expected path of the target federal funds rate is doing little-to-nothing to restore robust economic growth.  When the Fed lowers the expected path of the policy interest rate in its forecast is it because the Fed is truly adding monetary stimulus or is it because the Fed now expects a weaker economy?  In the latter case, the Fed would be seen as simply maintaining the status quo of weak, anemic growth.  See here for more on this point.

(3)  Large scale asset purchases have not been effective in driving down long-term interest rates.  If anything, it is the weak economy that explains most of the decline in yields.  Exactly.  While there are long-term structural changes (e.g.. aging, saving preferences in Asia, lower expected productivity growth) that may explain some of the decline, the fact that over the span of the crisis the 10-year treasury yield has gone from above 5.1% to 1.6% suggests a cyclical story.  Simply, the ongoing expectation of weak economic growth in advanced economies is pushing down yields.  The irony here is that the Fed, through its influence on global monetary conditions, could change economic expectations for advanced economies and raise long-term yields.  In a sense, then, the Fed is responsible for the low interest rates just not in the way most observers think.  

Woodford sees a nominal GDP level target that returns nominal GDP to a pre-crisis trend path as the best way forward for the Fed.  It implemented properly, this approach would not be susceptible to the above critiques.  Here is Woodford:

He even invokes the now-popular NGDP-below-trend figure to show that NGDP is 10-15% below where it should be. By implication, then, Woodford is accusing the Fed of effectively keeping monetary policy too tight since late 2008.  There is far more to the article, but how refreshing it is to see someone of Michael Woodford’s stature to endorse what Market Monetarists have been saying for the past four years.  Moreover, it adds to the growing momentum for monetary regime change at the Fed.

P.S. No mention of Market Monetarism and the influence it has had in promoting NGDP level targeting, but that is okay (though footnote 33 was a pleasant surprise).  What matters more is to minimize that vast amount of human suffering being caused by tight monetary policy.  Woodford’s article pushes us one step closer to that goal.
