The story of a remarkably stable US NGDP trend
Today revised US GDP numbers for Q3 were released. While most commentators focused on the better than expected real GDP numbers I am on the other hand mostly impressed by just how stable the development in nominal GDP is. Just take a look at the graph below. I have earlier argued that the development in NGDP looks as if the Federal Reserve has had a 4% NGDP level target since Q3 2009. In fact at no time since 2009 has the actual level of NGDP diverged more than 1% from the 4% trend started in Q3 2009 and right now we are basically exactly on the 4% trend line. This is remarkable especially because the Fed never has made any official commitment to this target. With market expectations fully aligned to with this trend and US unemployment probably quite close to the structural level of unemployment I see no reason why the Fed should not announce this - a 4% NGDP level target - as its official target. PS I might join the hawks soon - if the trend in NGDP growth over the last couple of quarters continues in the coming quarter then we will move above the 4% NGDP trend and in that sense there is an argument for tighter monetary conditions. PPS I am not arguing that monetary policy was appropriate back in 2009 or 2010. In fact I believe that monetary policy was far too tight, but after six years of real adjustments it is time to let bygones-be-bygones and I don't think there would be anything to gain from a stepping up of monetary easing at the present time.
