DEFINITION of 'Ceteris Paribus'

BREAKING DOWN 'Ceteris Paribus'

For example, when discussing the laws of supply and demand, one could say that if demand for a given product outweighs supply, ceteris paribus, prices will rise. Here, the use of "ceteris paribus" is simply saying that as long as all other factors that could affect the outcome (such as the existence of a substitute product) remain constant, prices will increase in this situation. Contrasts with "mutatis mutandis".
