FAQ: Aren't the NIPIs bounded?
No.
The NIPIs can go to 100. Or below zero, in theory.
Unlike the PMIs.
The NIPIs are scaled so that:
-
50 is for an equal volume of positive and negative news
-
100 (or 0) or for exceptionally strong or weak inflation newsflow, by historical standards
They should therefore be integrated variables, by construction - though they are not bounded.
100 would be like the maximum volume of inflation news seen in the history over a 30-day period but with every single news being positive.
That should have been a really rare event, but the exceptional volume of inflation news seen in recent months make it possible to go beyond 100.
Don't like the way we aggregate or scale the NIPI?
Or think this could be done in a way that better suits your needs?
We provide data as transparently as we can.
Our subscribers have access to the raw data, the basic entropy measures which we aggregate in the NIPI. Therefore, from our data, one can build indicators with different trade-offs (between noise and timeliness or between inflation perception and CPI accuracy, for instance).
Don't hesitate to reach out to discuss the details.
