Thanks Johannes, let me also give an example, but where the problem is
the other way around apparently (i.e., gretl is on the working end of
affairs).
Specifically, I'm talking about net financial wealth (Nettogeldvermögen)
of (German) private households in the old ESA95 system.
Here's the place on the Bundesbank website to where I have clicked my
way through the database jungle:
https://www.bundesbank.de/dynamic/action/de/statistiken/zeitreihen-datenb...
The funny thing is, I get no data displayed and an error saying "Die
Zeitreihe ist nicht gültig oder nicht verfügbar." (Invalid or not
available.)
However, now with the updated dbnomics 0.43 in gretl I am able to access
BUBA/BBK01/CE3K0I alright, with data from 1991Q1 through 2014Q4, as it
should.
What's the point here? Well, two things:
- The Bundesbank dataset Finanzierungsrechnung (financial flows) does
not seem to live in dbnomics directly (or does it?). Instead one has to
go to the catch-all BBK01 and know the code from other sources. Then it
works fine, though.
Hi Sven,
not an expert in this particular area of financial accounts, but I
probably can explain the reason, why the time series database of the
Bundesbank seems to lack data, especially in this particular area.
The main reason probably is that the Financial Accounts probably
switched away from the ESA 1995 methodology in 2014. Therefore, I
suspect that all these time series are not updated on a regular basis
anymore.
This then triggers a rule, that time series, which are not updated for,
I think, more than six months are to be removed from the website. I
assume that this was done to show to potential data users, that the data
they are using is outdated and they should switch to a newer, still
maintained, time series code.
If that makes sense in that particular case, is up for discussion.
I guess that dbnomics is storing the data and thus you are still able to
access it on their system. Nevertheless, it would be better if the
dbnomics datasets would be named more consistent.

- The Bundesbank web page data access has some gaps which do not seem
intended.
thanks
