One thing that occurred to me is that we should get rid of some functions for more recent years via @dates_active. I guess after 2017 or so, nobody was affected by this anymore? Or might one need it to calculate pension levels for older cohorts (do we support that?)?

Yeah, I have thought about it too. But then I thought, when we want to calculate the pension payment for someone born in say 1945 for year 2020 , then we need the function. (But I am never sure about the purpose of gettsim in this respect, we should talk about this)

Yip, this is exactly what I meant. I guess my question was whether we carry all information around so that this is possible? Could well be, I just have no idea.

Is it possible to earn Entgeltpunkte after accessing the pension? If so, this would make it impossible I suppose. Else it could work.

What do you mean by carry around? (doesn't this require to have calculated the pension in some earlier year/ or at least have observed the person? I was thinking about some cross sectional application )

Yes,it is possible to earn Entgeltpunkte after accessing the pension. (probably rarely done but possible)

Apologies, the "we" did not make much sense. What I meant is whether we can compute the pension in a backward-looking manner. I.e., if we observed cross-sectional variables in 2020 plus some others like pension start date, would it even be possible to calculate the pension of an 80-year-old who has been retired for 17 years?

Yes, it is possible to earn Entgeltpunkte after accessing the pension. (probably rarely done but possible)

And I think this case makes the above impossible. Else we'd need to distinguish between credits earned before accessing the pension and after doing so?

Thats right. That is with the current implementation we can only do this for people who have stopped working when they started to claim "Altersrente", which is the vast majority though.

Great, many thanks! Sorry for being a drag here!

No worries, improved the quality :)
