One is the claim that much of the progress against inflation is in some sense illusory, that underlying inflation is still well above 4 percent.
Now, there are enough measures of underlying inflation out there that if you pick and choose you can still manage to be pessimistic, but the preponderance of the evidence — plus the results of hands-free algorithms that use a consistent procedure to extract the signal from the noise — suggests underlying inflation around 3 percent and dropping.
The other is the claim that disinflation pessimists were simply applying standard economic models, so that the fault lay in the models, not themselves.
But that’s simply not true.
Standard models say that disinflation is very costly if persistent high inflation has become entrenched in expectations.
