What is scale of preference and tie ceiling

Scale of preference refers to the ranking of human wants in order of their importance. This is necessary because human wants are unlimited, but the resources to satisfy them are scarce. Therefore, individuals and societies must prioritize which wants to satisfy first.

Tie-breaking ceiling is a concept used in situations where there are multiple equally desirable options or solutions, and a decision needs to be made. It implies a limit or a rule that helps resolve the tie, ensuring a choice is made. This could involve a predetermined criterion or a further evaluation step to break the deadlock.
