Surplus economics is the study of economics based upon the concept that economies operate on the basis of the production of a surplus over basic needs. Economic Surplus By economic surplus is meant all production which is not essential for the continuance of existence. That is to say, all production about which there is a choice as to whether or not it is produced. The economic surplus begins when an economy is first able to produce more than it needs to survive, a surplus to its essentials. Alternative definitions are: The difference between the value of a society's annual product and its socially necessary cost of production. (Davis, p.1) The range of economic freedom at its [society's] disposal, extent able to engage in socially discretionary spending that satisfies more than the basic needs of its producers. (Dawson & Foster in Davis, p.45) Income minus essential consumption requirements. (Lippit in Davis p.81) The difference between what a society can produce and what a society must produce to reproduce itself.
