Brief Aside On Rosenberg's Money Problems


By Diane Coyle


"In the mid-1980s I worked on monetary policy in the UK Treasury (this was before Bank of England independence), and monetary targeting was the policy of the Thatcher Government. It was based on the simplistic monetarism Professor Rosenberg criticises toward the end of his blast against economics: control monetary growth and you would control inflation as the two were supposed to be closely related. 

It didn’t work, and the reason was quickly apparent: innovations such as ATMs and credit card use were changing the ‘velocity’ of money, the speed of its circulation, so the simple relationship broke down. The lesson was absorbed; there are no simplistic monetarist models in use now, more than 30 years on. It is clear that US economists are divided about the likely inflationary impact of the Biden stimulus, but those who are forecasting inflation now are not doing so for 1980s monetarist reasons, but in general for Keynesian reasons of demand growth far exceeding the supply side potential of the economy. Larry Summers, for instance, puts his concerns in terms of the output gap. 

Students are certainly not in general taught what this piece states. See for example: here.
