Over at Equitable Growth: In the 60 years since 1954, the Federal Reserve has been moved to cut the 3-Mo. T-Bill rate when a recession threatens by 2.0%-points or more 13 times--once every 4.6 years. There have been eight cuts of 4.0%-points or more--once every 7.5 years. There have been five cuts of 5.0%-points or more--once every 12 years.
To me that suggests that the Greenspan-Bernanke policies--aim for 2.0%/year inflation, with a 300 basis-point "natural" short-term safe real interest rate on top of that when the economy is in the growth-along-the-potential-path phase of the business cycle--were already too restrictive. Once every 12 years is too often to run into ZLB problems, unless you are a strong believer in Coibion and Gorodnichenko arguments that price inertia is due to serious costs to businesses of altering price paths.
