It’s only logical; NGDPT is the next big thing
Let’s filter out the noise and look at three big turning points:
1. The 1930s: A deep and prolonged deflation from 1929 to 1933 was associated with sharply higher unemployment. Economists drew the conclusion that policymakers needed to err on the side of expansionary policies, to prevent a repeat of the Great Depression. They did. And it worked.
2. The Great Inflation (1966-81): Higher and unstable inflation was associated with several problems such as unstable unemployment and distortions in capital markets. Though not as bad as the Great Depression, economists agreed that the Fed needed to hold inflation at low and stable levels. They continued to view business cycles as a significant problem, but noticed that the worst cycle in recent decades (the recession of 1981-82) was caused by a sharp slowdown in inflation. Thus inflation targeting should also stabilize growth, killing two birds with one stone. They said we needed a Taylor-Rule type policy to stabilize inflation around 2%. They succeeded. No more Great Depressions and no more Great Inflations.
3. The Great Recession: Now economists noticed that even if inflation was pretty well anchored, we could have quite a bit of real instability. Once low rates of inflation were achieved, it seemed like high and unstable unemployment was a much bigger problem than modest variations in inflation (say in the 0% to 4% range.) Now we need a nominal aggregate that will stabilize output better than an inflation target, while still producing fairly well-anchored inflation over the business cycle. That’s going to be NGDP targeting, or something closely related. It will happen. And they will once again succeed. And then no more Great Depressions and no more Great Inflations and no more Great Recessions. That’s called progress.
Economists on both the left and the right are gradually moving to NGDPT. Nick Rowe says that what convinced him is that it would have done much better in the recent severe business cycle. Severe problems are the problems you most want to prevent. NGDPT does that. Just today commenter W. Peden pointed to an endorsement of George Selgin’s (closely related) productivity norm by Allister Heath in The Telegraph. He offers a conservative version of the idea, but center-left economists like Michael Woodford, Christy Romer and Jeffrey Frankel are also switching to NGDP targeting.
This isn’t rocket science–economists learn fairly predictable lessons from each major policy failure. This one is no different. Central banks are conservative institutions so it will take a while for it to show up in the actual policy. But you can be sure they are paying attention, and know that NGDPLT would have done better than IT in 2008-09. (Of course when I talk about central banks understanding what went wrong I am excluding the ECB. There are in an entirely different category–still working on the lessons form the 1930s.)
The intellectual battle is almost over—time to consider what will go wrong under NGDPLT, and start working on the next improvement in monetary policy. I vote for nominal aggregate labor compensation (per capita) targeting as the next iteration.
