parity

Parity refers to equality of an amount or value, and it's used most often to refer to finance.

Par means "equality" — for example, something "not up to par" is not equal to what it should be. In a similar vein, parity means "equivalence." Farm parity is a system under which farm-produce prices are supported by the government to give farmers prices equal to a set level, thus supporting the farmers even if the market prices should fall.
