Ceteris paribus is a Latin phrase that translates as “other things the same” and is a frequently used expression in economics. It refers to a phenomenon in which two or more variables intervene and for which it is assumed that, with the exception of the variable that is under study, the rest remain constant and stable, e.g. if the price of rice decreases, ceteris paribus, the demand for it will increase.
It is widely used in marginalism and macroeconomics, its use becoming popular thanks to the English economist Alfred Marshall.
