What is a system of an academic carrier in Your country ... ? , and which is better ... ?

I have heard about two basic known systems of the academic carrier:

1. "Parisian" - throw grades like: assistant, adjunct, professor of the university, titled professor ... , and You may get throw them in the same university (in the same building, in the same room, at the same desk ...) depending on opinions of Your supervisors,

2. "Bolognian" - only two grades: post-doc and professor of the university ... , but after a period (e.g. 4 years) every academic is fired and must take a part in a competition to be employed again (in the same or another university).

What is the role of a good/bad author law and patent law in the academic carrier ... ? , ... especially in those above systems ...

How do You think ... ?
