Definition of ceteris paribus. Ceteris paribus is a Latin phrase meaning âall other things remaining equalâ. The concept of ceteris paribus is important in economics because in the real world it is usually hard to isolate all the different variables. An increase in interest rates will âceteris paribusâ cause demand for loans to fall. (Higher interest rates increase the cost of borrowing so there will be less demand for loans.
Parity is a situation where two or more things are equal. An example of parity is parity in income, where two or more groups of people earn the same amount of money.
