Bill Mitchell — The one-trick New Keynesian ponies are back in town

I learned long ago that when you consult a surgeon the recommendation will be surgery. After about 10 or more knee operations (both legs) as a result of sporting injuries, and, then some, to undo the damage done by previous surgery, I ran into a physiotherapist who had a different take on things. He showed me ways the body can respond to different treatments and retain the capacity for high-level training and performance even with existing damage. I still run a lot and his advice was worth a lot. The point is to watch out for one-trick ponies. The analogy is not quite correct because sometimes surgeons get it right. I don’t think the same can be said for a mainstream economist, who are also one-trick ponies. If you ask a mainstream economist what to do about macroeconomic policy they recommend hiking interest rates and cutting fiscal stimulus if the CPI starts to head north, irrespective of circumstances. But the message is getting blurred by realities, especially since the GFC. More pragmatic policy makers realise that just responding in the textbook manner hasn’t provided a sustainable basis for nations to follow. In the last week, we have seen the contradiction between the one-trick ponies, who are desperate to get back into their textbook comfort zone, and those who see the data more clearly. In Britain, one part of the Bank of England, the Financial Policy Committee has indicated the way forward is going to require careful policy support for businesses because many SMEs have loaded up on debt during the pandemic and face a precarious future. In the same week, a private sector bank economist, who is also an external member of the Bank of England’s Monetary Policy Committee, called for interest rate hikes and a deeper withdrawal of fiscal support (and central bank coordination of that support) to deal with, an as yet, unclear inflation threat....
