Say's Law
Further information: Say's LawSay's Law states that "The more goods (for which there is demand) that are produced, the more those goods (supply) can constitute a demand for other goods". Keynes summarized this "law" as asserting that "supply creates its own demand", though this interpretation has been criticized. The consumer's desire to trade causes the potential consumer to become a producer to create goods that can be exchanged for the goods of others, goods are directly or indirectly exchanged for other goods. Because goods can only be paid for by other goods, no demand can exist without prior production. Following Say's law, overproduction (in the economy as a whole, specific goods can still be overproduced) is only possible in a limited sense.

Famous quotes containing the word law:
“There is ... but one response possible from us: Force, Force to the uttermost, Force without stint or limit, the righteous and triumphant Force which shall make Right the law of the world and cast every selfish dominion down in the dust.”
—Woodrow Wilson (1856–1924)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
