Dear Allin, of course you're right.
Consider the following series for France:
-------------------------
Series: A.FR.BACK_BP6_EUR
Provider: IMF
Dataset: BOP (Balance of Payments (BOP))
Identifier: IMF/BOP/A.FR.BACK_BP6_EUR
Name: Annual – France – Net Lending (+) / Net Borrowing (-) (Balance
from Current and Capital Account), Euros
Dimensions, showing JSON mask form:
Frequency: Annual, {"FREQ":["A"]}
Reference Area: France, {"REF_AREA":["FR"]}
Indicator: Net Lending (+) / Net Borrowing (-) (Balance from Current
and Capital Account), Euros, {"INDICATOR":["BACK_BP6_EUR"]}
-------------------------
pd = 1; 20 observations, 1999 - 2018
The values range from -25286 to 48810, surely these cannot be pure
Euros, instead probably million Euros such that the maximum is 48.8bn
(in the American sense, bn=10^9). But I don't see that scaling information.
I see what you mean. It turns out that gretl isn't missing anything in
the JSON retrieved from dbnomics -- the scale is simply not stated. I
checked further and this is also the case with IMF BoP data for
countries other than for France and for currency other than Euros.
But if you go directly to the IMF you see that the numbers are indeed
in millions (Don't know if this URL is portable but I'm looking at,
e.g.,
http://data.imf.org/regular.aspx?key=60961513 )
So something is not being communicated from the IMF to dbnomics; I've
posted a comment on their forum.
