In Germany the right is called "Urheberrecht" which literally translates to "author's right". And while you can license your work and sign away the usage, you cannot by definition sign away the fact that you are the author of a work.
But they exist to a (very) limited extent even in the US.
Yes, Louisiana somewhat notwithstanding, the US is basically common law like the UK (and much of the Anglosphere/Commonwealth).
As a bit of trivia, the MIT License was essentially created because of issues with "just" making X public domain. https://opensource.com/article/19/4/history-mit-license

I assume Germany has something like this (possibly a EU requirement). It would cover more than just ghostwritten books.
Most software is written in a similar manner. Microsoft didn't write windows, lots of ghostwriting programmers did.
But we also the right to be named as author is not a requirement to be named as author.
