[O]pen market operations (OMOs) and helicopter drops will only spur aggregate demand growth if they are expected to be permanent. This idea is not original to Market Monetarists and has been made by others including Paul Krugman, Michael Woodford, and Alan Auerback and Maurice Obstfeld. Market Monetarists have been advocating a NGDP level target (NGDPLT) over the past five years for this very reason. It implies a commitment to permanently increase the monetary base, if needed.
Doing so would help in the following ways:
The key reason is that it would create an expectation that some portion of the monetary base growth from the asset purchases would be permanent (and non-sterilized by IOER). That, in turn, would mean a permanently higher price level and nominal income in the future. Such knowledge would cause current investors to rebalance their portfolios away from highly liquid, low-yielding assets towards less liquid, higher yielding assets. The portfolio rebalancing, in turn, would raise asset prices, lower risk premiums, increase financial intermediation, spur more investment spending, and ultimately catalyze a robust recovery in aggregate demand. (One could also tell a New Keynesian story where the higher future price level implies a temporary bout of higher-than-normal inflation that would lower real interest rates down to their market clearing level.)
The key to the above story is that some portion of the monetary base expansion is expected to be permanent. If the public believes the Fed’s asset purchases are not going to be permanent and therefore the price level and nominal income will not be permanently higher, the rebalancing will not take place. I bring this up because this same point applies to helicopter drops or any other kind of fiscal policy stimulus.
Another way to see how the above figure reveals monetary policy failure is to compare the Fed to the Bank of Japan. It too tried temporary monetary injections but then switched to permanent ones under Abenomics:
[T]he Bernanke Fed never tried Abenomics. That is, for all the Fed has done over the past five years it never tried to do the kind of monetary regime change now being done by the Bank of Japan. A year ago, Japanese monetary authorities shook things up by credibly committing to permanently raising the nominal size of the Japanese economy. The evidence so far shows this program to be a smashing success. From the start, the Bernanke Fed took the opposite approach. It credibly committed to a temporary expansion of its balance sheet. The U.S. monetary injections, therefore, were never intended to be permanent and this makes all difference in the efficacy of monetary policy.
So for all the praise the Bernanke Fed gets for preventing the second Great Depression, it should be equally noted that it allowed the long slump. By failing to do Abenomics for the U.S. economy, the Bernanke Fed effectively kept monetary policy tight for the past five years. There is no other way to say it.Okay, maybe there is another way to say it. The Bernanke Fed failed to meaningfully address the endogenous fall in the money supply and the decrease in money velocity. The Bernanke Fed could have done an American version of Abenomics, like nominal GDP level targeting, that would have arrested these developments. Instead, it did not and passively allowed total dollar spending to remain depressed. This failure to act is no different than an explicit tightening of monetary policy in terms of damage done to the economy. The only difference is that the public is more aware of the explicit form.
So again I ask, what do you see in the above figure?
P.S. Yes, the Fed’s ad-hoc decision making contributed to this failure.
